Sun. 1 - 2pm Orange County Convention Center - S230 B Hot-Dip Galvanized Steel—Addressing the Growing Corrosion Problem—Forum
This presentation will inform and educate architects, engineers, and other specifiers about hot-dip galvanized steel and how it can address the growing corrosion problem throughout North America. Upon completion of this presentation, attendees will be able to: a. Recognize the corrosion issues confronting North America b. Describe how zinc coatings, specifically hot-dip galvanizing, can protect against steel corrosion c. Incorporate sound corrosion protection into the design of steel products that can significantly reduce maintenance costs over the life of a project Every day you see signs of the increasing corrosion problem throughout North America. It is so prevalent today, most of us don’t even notice it, as we take corrosion for granted as a natural, unavoidable, and uncontrollable condition that affects our city or community and wastes tax dollars. This presentation will examine common sights of corrosion we all see daily. Corrosion is a natural phenomenon, and thus can never be completely eliminated; however, it is a misconception that nothing can be done. Estimates show 25 to 30% of steel corrosion could be eliminated if proper corrosion protection methods were employed. Presented by Kevin Irving, AZZ Galvanizing Services

Sun. 1 - 4pm Orange County Convention Center - S230 E How to Avoid Premature Coating Failures Forum
This practical and informative tutorial will discuss how to prevent premature coating failures. Premature coating failures continue to cost contractors, facility owners, shipbuilders, and paint manufacturers substantial sums of money every year in additional labor and materials, legal fees, and in opportunity costs. These out-of-pocket costs are not budgeted items; therefore, they come directly from bottom-line profits. However, more importantly, premature coating failures often cause irreparable damage to customer relationships and future business opportunities with existing clients. This tutorial is based on real-life coating failures investigated by the presenter during his 33 years in the coatings industry. It is filled with numerous examples from approximately 30 different failure investigations with pictures of actual coating failures on steel and concrete. It will provide participants with practical knowledge, based on principles and on errors made by others, regarding how to reduce or avoid premature coating failures.

Mon. 9 - 9:25am Orange County Convention Center - S320 D Symposia: Corrosion in Nuclear Systems An Adaptive-Predictive Probabilistic Methodology for Forecasting Localized-Corrosion-Induced Damage
Pavan Shukla - This paper presents an adaptive-predictive probabilistic methodology for forecasting localized-corrosion-induced pit population and pit depth distributions. Nuclear power plant (NPP) operators are required to periodically inspect components by visual and volumetric examinations to maintain integrity and ensure safety. However, as NPPs age, more frequent inspections would be needed for maintaining component integrity. To define inspection schedules, a framework is needed that balances risk and cost and ensures safety. This paper presents a methodology including a model that could be used to predict localized corrosion-induced damage of NPP components. For example, if a component is undergoing pitting corrosion in an environment, the model predicts the pit population and the pit depth distribution as a function of time (i.e., the fraction of pits at a particular depth at a particular time). The methodology and associated model accounts for previous inspection data, ran

Mon. 9 - 9:25am Orange County Convention Center - S310 A Symposia: Corrosion Issues Related to Water Systems and the Environment THE IMPACT OF CORROSION ON MINE WATER SUPPLY SYSTEMS
Zoe Coull, Sergio Gonzalez-Arrano, María Ramírez, Rubén Muñoz, Jaime Zúñiga - Water scarcity is one of the most important challenges for the mining industry in Northern Chile. Most of the mining operations are located in a desert climate, at high altitudes, where the main local water supply is from limited, typically low quality groundwater sources. Most of the mining activities would outlast the local water reserves, and therefore many projects have considered, and continue to develop, the use of seawater or desalinated water to supply their operations. The natural corrosivity of seawater or desalinated water impacts not only on materials selection and costs but it also affects the mine process, the system availability, safety and environmental issues, among other factors. This paper discusses issues encountered with internal pipe corrosion and how the engineering design is evolving to deal with this issue in mining water supply projects.

Mon. 9 - 9:25am Orange County Convention Center - S310 G-H Symposia: Direct Assessment—The Continuing Dynamic Development of the Processes A Plant Health Assessment for a Gas Oil Separation Plant (Case Study)
Mohammed Al-Barout, Mohammed Al-Subaie - A plant health assessment was conducted for one of Saudi Aramco’s Gas Oil Separation Plants (GOSP). The assessment’s primary objective was to provide an action plan to address the likelihood of design and operational concerns, identify potential areas of improvements, and thus provide recommendations of the remedial actions necessary to maintain safe and reliable operations over the facility’s lifespan. The assessment covered different disciplines with an integrated and holistic approach. Theses disciplines included Materials and Corrosion Control, Inspection, Mechanical, Process, Instrumentation and Rotating Equipment. The paper will discuss the major findings and recommendations of this assessment pertaining to materials, corrosion control and Inspection. Frequent corrosion problems were found at Degassing Vessel and Low Pressure Production Trap (LPPT) gas outlet piping due to water carry over from these vessels. In addition, crude oil line

Mon. 9 - 9:25am Orange County Convention Center - S220 A Symposia: Advances in Materials for Oil and Gas Production Evaluation of Temp. Installed Well Zone Isolation Equip. After Long-Term Exposure to a Caesium Forma
Perry Nice, Roberto Morana, Eugenio Lo Piccolo, Lucrezia Scoppio - Well Zone Isolation Equipment or “Straddle System” was installed during a temporary well Plug and Abandonment (P&A) for a period of 448 days within a North Sea HPHT well. This “straddle system” comprises of two packers separated in between by a number of tubing joints. The two packers were manufactured from nickel alloy 718 (UNS N07718) and super martensitic stainless steel 13Cr (UNS S41425) and the tubing joints super martensitic stainless steel 13Cr grade 110 (UNS S41426). The straddle system was run and its packers installed or set whilst a 1.85 s.g. oil based mud was located in the well, thus trapping this mud system in the annular space between the well casing and the straddle systems tubing joints. In preparation for this temporary P&A of this well then the oil based drilling mud system was displaced with a 2.0 s.g. caesium formate mud. This would then leave the inner surface of the straddle system exposed to t

Mon. 9 - 9:25am Orange County Convention Center - S330 D Symposia: Fluid-Induced Degradation—Corrosion, Erosion, and Their Interactions The Influence of Steel Metallurgy on the Initiation of Localized CO2 Corrosion Caused by Varying Flo
Emad Akeer, Bruce Brown, Srdjan Nesic - The environmental conditions encountered in oil and gas wells can cause severe corrosion to carbon steel tubing and pipelines and the microstructure and chemical composition of steel are considered to be important variables that affect the resistance of steel to corrosion. Five different pipeline steels with different chemical composition and microstructure were chosen to investigate the effect of their metallurgy on the attributes of formed iron carbonate and related corrosion phenomenathat could lead to localized corrosion.The effect of a high liquid flow rate on a pre-formed iron carbonate corrosion product layer was studied at 80°C, pH 6.6, and 1.5 pCO2for each steel. Iron carbonate layers,initially formed on each steel at low shear stress (35 Pa), were exposed to high shear stress (535 Pa) for 3 days. For all tested steels, the formed iron carbonate layer reduced the general corrosion rate to less than 0.5 mm/y after 2 days, but the incr

Mon. 9 - 9:25am Orange County Convention Center - S330 F Symposia: Inhibitors—Vapor Transported and Surface Coatings/Rust Preventatives Electrochemical Noise Analysis for Different Green Corrosion Inhibitors for Mild Steel Exposed to 0.
adham ahmed - The corrosion Inhibition for mild steel exposed to 0.5 M H2SO4 has been studied using electrochemical noise analysis (ENA) and electrochemical impedance spectroscopy (EIS). Four different herbal compounds, Anise ( Pimpinella Anisum), Caraway (CARUM Carvi), Cumin (Cuminum Cyminum) and Hibiscus (Hibiscus Sabdarriffa) have been tested as green corrosion inhibitor for mild steel exposed to 0.5 M H2SO4. The comparative analysis of the results obtained showed that ENA is an effective tool for screening of new corrosion inhibitors. Analysis of noise data demonstrated the need of removal of the drifts in the potential and current fluctuations during the measurement periods. The results gathered show that the inhibition efficiency reached a maximum for an inhibitor concentration of 1 ppm for the first 48 hours of exposures. Generally, ENA showed a good correlation with EIS in this study.

Mon. 9 - 9:25am Orange County Convention Center - S330 A Symposia: Corrosion Monitoring in Subsea Installation Corrosion monitoring of a polymer coated subsea pipe with ultrasound
Ingar Stian Nerbø, Oystein Baltzersen, Harald Sleire, Ibrahim Karaga, Vegard Fiksdal, Sarbyjot Haarberg, Malfrid Guldstein - Ultrasound is a standard method in non-destructive testing to measure the wall thickness of steel pipes. By placing a measurement probe on the outside of the pipe, the wall thickness can be measured while the pipe is in operation. Permanently mounted ultrasound probes can be used for highly sensitive wall thickness monitoring, being able to detect wall thickness changes down to the micrometer. The high sensitivity allows for rapid determination of corrosion rates, which could give feedback on the effect of inhibitor chemicals. For subsea applications, steel pipes are often covered by an insulating coating. Such a coating makes thickness measurements with ultrasound more challenging, as the coating usually is of a material that absorbs ultrasound, leading to a lower signal to noise level in the measurement. The coating will also result in additional echoes in t

Mon. 9 - 9:25am Orange County Convention Center - S220 E Symposia: Deepwater Corrosion and Scale Inhibitors Barium Sulphate Kinetics on Steel Surfaces at Different Supersaturation Ratios
Benissa Tolaieb - Barium sulphate surface deposition kinetics, at different supersaturation ratios in realistic oilfield brines, were investigated in a flow system at a constant temperature of 75 ⁰C. The supersaturation ratios of the mixed brines vary over a wide range of Ba2+ ion contents (150 ppm, 100 ppm, 80 ppm, 50 ppm and 20 ppm). The expected barite formation was predicted using the Multiscale software package. The barite surface deposition pattern was monitored by a sensitive differential pressure technique tool with respect to the change of pressure across the test capillary when scaling. It was found that the barite surface induction period is inversely proportional to the supersaturation ratio and the whole process seems controlled thermodynamically at high supersaturation ratios, but this is not the case in the lowest barium contents. This was obvious when plotting the observed induction time data versus the predicted supersaturation ratios. The exponential growth period

Mon. 9 - 9:25am Orange County Convention Center - S230 A Symposia: Assessment and Control of Reinforcement Corrosion in Concrete Structures Corrosion of Underwater Reinforced Concrete Tunnel Structures
Miki Funahashi - The reinforced concrete tunnels structures located under water are generally protected from rebar corrosion using waterproof membranes as the first defence. However, once the waterproof membrane fails caused by various reasons, including poor installation, aging, the movement of the structure settlement, soil pressure, etc., seawater or blackish water gets to the concrete under the waterproof membrane, resulting in water leakage. The mechanism of the rebar corrosion caused by chloride contaminated water is quite different from the structures exposing to marine or de-icing salt environment because the leakage water travels through cracks in concrete. When a crack in concrete reaches the internal concrete surface of the roof and walls, obvious water leakages are visually detected. The salt contaminated water which reaches to the internal surface flows along the concrete surfaces, and then chlorides diffuse into the concrete. As a result, wide-spread corrosion occurs.

Mon. 9 - 9:25am Orange County Convention Center - S310 E-F Symposia: Managing Corrosion with Polymers Behavior of TPU Jacketed Tubing Versus Bare Alloy Tubing
Mike Pellegrini, Samuel Mishael, Krista Heidersbach, Robert Rettew - The historic use of bare 316 stainless tubing on offshore topsides has suffered from multiple failures across several operators and multiple geographic regions. Tubing leaks have been caused by external corrosion, vibration, and fitting leaks. Selected case histories of leaks will be presented. Properly designed polymer jacketed 316 stainless steel tubing offers an economical and reliable solution to prevent failure. Lower capital cost can also be realized when the design incorporates bundling of multiple tubes into single flat packs. Laboratory corrosion testing results of jacketed tubing will be presented. Benefits such as safety improvements, tray space cost savings and faster installation will be discussed. Product applications and successful installations will be highlighted.

Mon. 9 - 9:25am Orange County Convention Center - S220 D Symposia: Sour Corrosion Symposium SSC Resistance of 316Ti in Brine under Highly Sour Conditions
Gerit Siegmund, Josef Noga, Guenter Schmitt - The applicability of the alloy UNS S 31635 (316Ti, 1.4571) in chloride containing sour environments is presently controversially discussed. According to ISO 15156 Part 3 this material shall be used in chloride-containing media only under H2S partial pressures up to 1 bar. However, this material has been used for decades in many highly sour industrial environments without any reported failure. The ongoing discussions on the application limits of the alloy UNS S 31635 prompted new experimental work to evaluate the SSC and pitting susceptibility of this material in highly sour brines at room temperature. Round tensile specimens were subjected in triplicate for each set of conditions under 70% and 90% of the actual yield stress for 720 h fully submerged in brine with 1.000 mg/L and 30.000 mg/L chloride, respectively, in equilibrium with a gas phase containing 16 bar H2S + 16 bar CO2 and 16 bar H2S + 8 bar CO2, respectively.

Mon. 9 - 9:25am Orange County Convention Center - S320 G Symposia: Corrosion and Scaling in Geothermal Applications Prediction and Monitoring of Scaling and Corrosion In pH Adjusted Geothermal Brine Solutions
Keith Lichti, Kevin Brown - The risk of voluminous silica scaling limits many geothermal energy plants to steam and brine separation temperatures above the saturation limit for silica in the separated brine. The impact of these limits are compounded in the face of demand for secondary heat extraction using binary plant that can significantly increase energy efficiency from geothermal fluids. Options for additional energy extraction include increase in pH to increase the solubility limit for silica and decrease in pH to delay the time for onset of polymerisation reactions for colloidal silica sufficient to allow reinjection to a reservoir where elevated temperature will lower the silica saturation index. These two scale control methods can have significant impact on localised corrosion in chloride rich brines. The scaling and corrosion risks can be modelled theoretically to predict ideal conditions for enhanced energy production with minimal risk of corrosion, however, prudent opera

Mon. 9:25 - 9:50am Orange County Convention Center - S320 D Symposia: Corrosion in Nuclear Systems An Aspect for the mechanisms of primary stress corrosion cracking of Ni based alloys and austenitic
Nobuo Totsuka - Recently it has been reported that the basic mechanism of PWSCC is a type of HE( hydrogen emblittlement) and the role of hydrogen in the metal may be to accelerate low temperature creep, according to the results of the hump-SSRT tests and the rapid straining electrode tests using Ni based alloys and austenitic stainless steels. However there is big difference between cracking behavior of Ni based ally and austenitic stainless steel under static stress and strain condition such as constant load test or reverse U-bend test. Ni based alloy has susceptibility to PWSCC under such condition, but austenitic stainless steel does not. In this paper these difference between Ni base alloy and austenitic stainless steel will discuss based on the mechanism of PWSCC.

ROBERT POMPE, Ola Lyckfeldt, Lars Eklund, Jan-Erik Svensson, Lars-Gunnar Johansson - In the combustion of bio-based fuels the critically exposed burner parts in small boilers are typically uncooled and are usually made of FeCrNi alloys. These materials can suffer attack from the ashes because of the formation of alkali chromate. The reaction depletes the protective oxide in chromia, leading to accelerated corrosion. Selected “acidic” ceramic coatings based on Ti, Si, B and P have been evaluated for use as sacrificial layers to prevent the initial reaction of alkali and chromium. An accelerated oxidation test method including mild thermal shock has been utilized that previously proved useful to provide application-relevant results. A comparison of coated and uncoated specimens was performed with the austenitic high temperature steel 253MA as a substrate. The results indicated that the alkali released from the ash reacts with the respective “acidic” elements in the deposited coatings

Zia Chaudhary - In SABIC industrial plants, a large quantity of seawater is used in providing a cooling system for removal of exothermic heat generated in the reactors. Large size concrete cylinder pipes (CCP) are used as supply and return lines between the reinforced concrete seawater reservoirs and the plants. These CCP pipes are buried in soil, which is contaminated with chlorides due to very low seawater table. This paper describes the results of diagnostic investigations carried out to determine the condition of two (supply & return) pipelines that have been in service since 1984. The CCP pipes are manufactured conforming to AWWA C303 and consist of a 4-6 mm thick steel cylinder and 6-8 mm diameter steel bars wounded helically around the cylinder. The steel cylinder and bars are encased in 20 mm thick 1:1.5 or 1:2 cement mortar on the internal and external surfaces applied by centrifugal spraying to obtain a dense internal lining and external cover. The pipes are factory coate

Xinming Hu, Anne Neville, Kabir Raheem, Abdulmuhsen Akbar - This work has been carried out to investigate the effect of iron carbonate films formed on X65 pipeline steel on the material degradation mechanisms in erosion-corrosion. The experimental procedure includes a pre-corrosion process to form four types of corrosion films in different conditions: transparent, cementite, iron carbonate, and iron carbonate/cementite. The erosion-corrosion experiments were conducted using a recirculating impingement apparatus. In-situ corrosion rate values were monitored at a flow velocity of 7m/s, 50oC with addition of 800 mg/L sand in Forties brine saturated with CO2. The effects of the pre-formed films and the mechanisms relating to corrosion and erosion-corrosion processes have been identified and analysed using surface analysis techniques (SEM, AFM) and nano-indentation. It has been found that the erosion-corrosion conditions in this study severely damage the pre-formed corrosion films and h

Marc Lehmann - The reliance on production chemicals, such as scale and corrosion inhibitors, to provide protection for subsea systems from flow assurance and integrity management issues has led to more stringent product quality requirements as the applications have become deeper, further away (tiebacks), and more demanding with respect to product performance, stability, deliverability, and compatibility with the materials of construction. The qualification of chemicals for squeeze application in subsea wells differs from that for continuous subsea application. However, in the context of systems assurance the processes involved in product selection, testing and application for the two types of application are similar. This paper contrasts the considerations for the two types of applications with respect to; (1) how system conditions are modeled, (2) the differences in the objectives of performance testing, (3) how the method of product placement impacts performance, (4) the differen

Mon. 9:25 - 9:50am Orange County Convention Center - S330 A Symposia: Corrosion Monitoring in Subsea Installation Using permanently installed ultrasound monitoring to maximize the lifetime of a pipeline
Oystein Baltzersen, Roy Johnsen - Manual ultrasound inspection is the most common way to measure pipeline wall thickness quantitatively. By using permanently installed UT sensors and automated acquisition/processing, it is possible to improve the accuracy/resolution which can be achieved significantly compared to using manual UT. The main reason for this improved performance is that that variation due to the operator, and uncertainty in exact probe placement are removed by using an automated system. A new non-intrusive ultrasound based system has been developed for wall loss monitoring applications, and a pilot series of this system has been installed on a 24” pipeline. The pipeline is located on land, and has operating conditions which can give wall loss rates of several mm per year. It is a significant challenge to operate and maintain these pipelines effectively, and the operator has long experience with manual UT to provide decision aiding information for such activities.

Abdul Razzaq Al-Shamari, Abdulwahab Al-mithin, Surya Prakash, Tareq al-masoud, Arnab Gupta - The springs made from Inconel X-750 and used in Oxygen Scavenger service have failed by extensive corrosion within a short span of two years. The metallurgical compatibility between the material of spring and the process fluid is excellent. After through investigations including deposits analysis of deposits found inside the valve it was found that vapors of the oxygen scavenger have been carried into the spring chamber and condensed into liquid and then degraded due to constant influx of air through a breather valve connected to the tank. A detailed study of design of the chemical day tank was carried out it was found that the failure has actually occurred due to a gap of communication between the designer and supplier of the chemical day tank and the client. This paper highlights the findings of the investigation carried out and the possible recommendations that can be put in place to avoi

Ray Case, Hernan Rincon, Dale McIntyre, Shanen Hernandez - To assess the susceptibility of series 300 stainless steels to stress corrosion cracking under sour service conditions a stochastical model is developed. The model is based in the hypotesis that the critical conditions for crack initiation and propagation are satisfied by the presence of metastable pit regime found in H2S containing environment. The model determines the probability of cracking by forecasting the most likely elapsed time to achieve sustained crack growth. The boundary conditions for the stochastical model are provided by the experimental evaluation of the pit survival rate, using weak potentiostatic polarization up to 100 mV above the open circuit potential. To validate the model, service conditions similar to actual field cases of stress corrosion cracking were simulated experimentally. The model forecasts were in agreement with typical field times to failure within 95% certainty in all the occasions evaluat

Pu Gu - Boron-free E-CR glass fibers behave differently than boron-containing E-Glass fibers in acidic environment especially in strong acids.  Corrosion and stress rupture behaviors of E-Glass fibers with and without boron in acidic environment were carefully analyzed in our recent corrosion studies.  The effect of boron on E-Glass fiber acid resistance was studied using weight loss, SEM/EDS analysis, and stress rupture test methods.  The glass leaching mechanism is discussed based on a detailed analysis of E-Glass fibers with varying level of boron.  The local chemistry of boron species in E-Glass is used to explain congruent dissolution of B, Al, and Ca, which contrasts with the ion exchange mechanism as suggested by most literature.  The modified glass chemistry leads to significantly different leaching mechanism in acidic environment and results in superior acid corrosion resistance and improved mechanical performance for the boron-free E-CR glass fibers when used in a fiber re

The inhibition efficiency was found to change with variation in concentration of the inhibitor, time of immersion and temperature. The adsorption of the inhibitor molecule onto the metal surface was found to obey El-Awady kinetic thermodynamic and Frumkin adsorption isotherm. The activation energy (Ea) and other thermodynamic parameters indicate a strong interaction between the inhibitor and the mild steel surface. Polarization measurements indicate that CNP act as a mixed type inhibitor.SEM study confirmed the adsorption of inhibitor molecules on mild steel surface.

Muhamad Andhika, Jonathan banks, Simona regenspurg - Located at tectonic plate boundaries, Indonesia holds an enormous potential of geothermal resources. From estimated 27 GW potential, only 4 % electricity is currently produced from high temperature geothermal fields. The silica concentration in these high temperature geothermal brines is usually very high (several hundred mg/L). This represents one of the main obstacles for binary geothermal plant operation due to potential silica precipitation (scaling), which frequently causes operational problems by clogging the pipelines, reinjection wells, and even the pores of the near boreholereservoir region (injection site). To prevent such uncontrolled silica precipitation, this study aims in developing a method of fast silica removal from the brine. A promising tool to monitor the kinetics of scale formation is the ultrasonic probe, which allows online measurement of crystallization and crystal growth. A 0.1 M silica solution was prepar

Heather Ramsey, Thomas Johnson, Don Kelley - In order to meet more stringent EPA guidelines, the power industry must now build or retrofit their facilities with flue gas desulfurization (FGD) systems. A critical part of these systems is the FGD absorber. A common building material for the absorbers has been Duplex 2205 and 255 Alloys; however, the 2205 Alloy is showing signs of premature corrosion throughout the industry. The root cause of this corrosion is still under investigation, but with some absorbers lasting less than 18 months a repair regimen is sorely needed. This paper will discuss the issues surrounding 2205 Alloy corrosion as well as methods to rehabilitate and protect both old and new absorbers with Epoxy Vinyl Ester Polymer lining. The paper will also review the proper cleaning, surface preparation, application process, and choice of Epoxy Vinyl Ester Polymer lining to protect 2205 Alloy and prevent its premature breakdown in this environment.

Ryan Meyer - Uncertainty regarding the political viability of developing a centralized long-term repository for the storage of used nuclear fuel has increased the likelihood that used fuel will be stored in Dry Cask Storage Canisters (DCSCs) for periods much longer than originally anticipated. As a consequence, these canisters will potentially be subject to forms of degradation not considered in the original design basis. Atmospheric stress corrosion cracking (SCC) is one degradation mechanism that has the potential to occur in DCSCs as a result of extended service in marine or coastal environments. As part of a mitigation strategy, nondestructive examination (NDE) of canisters may be performed to identify and characterize atmospheric SCC flaws. This paper examines several technologies with respect to their capability for detecting and monitoring atmospheric SCC in DCSCs.

JIANYU XIONG, YongJun Tan, Nam Dang Nam, Maria Forsyth - Austenitic stainless steels are widely used in industries because of their appropriate mechanical properties, good corrosion resistance and weldability. The welding process of austenitic stainless steels leads to modifications of local composition and microstructures and thus results in localized corrosion behaviour. Standard cyclic polarization method (ASTM G61 - 86(2009) has been used to evaluate relative localized corrosion susceptibility. An indication of the susceptibility to initiation of localized corrosion in this test method is given by the potential at which the anodic current increases rapidly, i.e. the breakdown potential. An issue in cyclic polarization measurements is large scatter in the breakdown potential. This issue is even more acute in the cases of testing a welded joint where different heat affected zones exist. Techniques such as Local electrochemical cells have been developed to perform local potential

Frank Cheng - Development of high-strength steel pipeline technology would enable the pipeline industry to realize significant cost-savings by reducing the pipe wall thickness and increasing the operating pressure to satisfy the construction of long-distance, large diameter and high operating pressure pipelines. However, the pipelines experience severe environmental conditions, e.g., significant ground movement, resulting in additional stresses/strains exerting on the pipe wall. In this work, several industrial models available for assessment of failure pressure of pipelines were evaluated with respect to various grades of pipeline steel and depths of corrosion defect. Moreover, a finite element (FE) model was developed to simulate the complex stress/strain conditions potentially exerted on the high-strength steel pipelines due to the synergism of internal pressure, soil strain and local stress/strain concentration at corrosion defects. The corrosion behaviour of the steel was inves

Jean Kittel, Nicolas Ferrando, Cecile Plennevaux, Thierry Cassagne, Michel Bonis, Francois Ropital, Marion Fregonese - pH prediction represents a crucial step before selecting materials for use in sour oil and gas wells as regards weight loss corrosion and H2S cracking. Among the numerous parameters which determine the equilibrium pH, important ones are CO2 and H2S partial pressures (PCO2 and PH2S respectively), the total pressure, the ionic strength and the chemical composition of the solution, and the temperature. Most models used by oil and gas operators present a too narrow range of validity for these parameters, which makes them inappropriate for high pressure and high temperature (HPHT) fields or for CO2 reinjection. This paper presents modeling improvements which allows extending the prediction validity in temperature and pressure to respectively 200-250°C and above 200 bar of acid gases, and for an ionic strength up to 5 mol.kg-1.

Faisal Al-Mutahhar, Gusai Al-Aithan, Kenneth Roberts, Siamack Shirazi, Edmund Rybicki, John Shadley - When CO2 corrosion takes place, iron carbonate scale (FeCO3) may form under certain conditions. The role of a FeCO3 layer in reducing corrosion rates in sand–free environments has been studied by many investigators. However, the protection offered by FeCO3 scale when sand is produced is not well defined. This paper describes work conducted to characterize the resistance of iron carbonate (FeCO3) scale to erosion by solid particle impingement. Dry and wet FeCO3 scales were subjected to direct impingement by sand at various impingement angles. Scales were pre-formed in a flow loop at 65-93° C, from 6.1-6.5 pH, and 2.4 bar CO2 pressure and then removed from the flow loop for direct impingement testing. . The erosion pattern of the scale was characterized by scanning electron microscopy (SEM). Specimens with iron carbonate scale were partially eroded with sand at an impact angle of 60

Marita Berndt - Assessment of the long-term durability of concrete repairs on existing structures can provide useful data to support selection of strategies for ongoing remediation and service life extension. Condition surveys of large reinforced concrete storage sheds enabled study of repair methods for different forms of damage and deterioration. Reinforced concrete piles supporting the sheds exhibited multiple deterioration mechanisms and had undergone various repair techniques over 30 years. Deterioration included a combination of reinforcement corrosion, alkali-silica reaction and salt hydration distress (or physical salt attack). Of these, reinforcement corrosion was the greatest concern due to the impact on load bearing capacity of the piles. Floor slabs of the storage sheds had experienced different types of cracking and been exposed to sugar attack and heavy vehicle traffic.

Smita Jauhari - ABSTRACT  Schiff base 4-Chloro-N-[(2-chloroquinolin-3-yl)methylene]aniline was synthesized, and its inhibitive effect for mild steel in 1M HCl solution was investigated by weight loss measurement and electrochemical tests. . From the weight loss measurements and electrochemical tests, it was observed that the inhibition efficiency increases with the increase in the Schiff base concentration and reaches a maximum at the optimum concentration. This is further confirmed by the decrease in corrosion rate. It is found that the system follows Langmuir adsorption isotherm.

Jon Kvarekval, Anette Pedersen - Corrosion inhibition of carbon steel in mixtures of water and monoethylene glycol saturated with H2S and CO2 has been studied using research formulations with different active inhibitor compounds.  Experiments have been carried out in glass cells at ambient total pressure and various temperatures and ionic strength. While satisfactory inhibition of general and weight loss corrosion was possible to achieve with all the inhibitors tested, the findings demonstrate the challenges of mitigating pitting and other types of localized corrosion attacks in this enviroment. The addition of glycol to the H2S/CO2/H2O system was found to further complicate testing of corrosion inhibitors, as the steel coupons appeared to become more susceptible to localized edge and crevice attacks on areas in vicinity of the coupons holders. The test methodology and the chemical aspects of inhibitor treatment in sour glycolic environments are discussed on the basis of these and

Mon. 9:50 - 10:15am Orange County Convention Center - S320 E Symposia: High-Temperature Issues and Materials for the Process Industry Oxidation Behavior of Alumina-Forming Austenitic Steel
Bruce Pint, Kinga Unocic, Sebastien Dryepondt, Aurelie Rouaix-Vande Put, Michael Brady - Alumina-forming austenitic (AFA) stainless steels exhibit a unique combination of high temperature creep strength and corrosion resistance. By forming a protective alumina scale, AFA steels exhibit significantly better corrosion resistance than conventional, chromia-forming stainless steels and even Ni-base alloys. This improvement is a significant benefit for a number of advanced power generation and chemical process applications where materials are often limited by their oxidation resistance rather than their creep resistance. Laboratory exposures have been conducted in a number of environments at 550°-800°C including (1) wet air to simulate exhaust gas for thin-walled heat exchangers, (2) steam and (3) high C activities with and without water vapor at 1-10 bar. Oxidation rates for AFA were compared to conventional candidate alloys as well as other Fe- and Ni-base alumina-forming alloys. The

Mon. 9:50 - 10:15am Orange County Convention Center - S330 E Symposia: Control of Corrosion in Oil and Gas Production with Inhibitors Investigation of Pitting Corrosion and Inhibition in Sweet Conditions
Xinming Hu, Anne Neville, Ismarullizam Ismail - Sweet and sour pitting related failures are a prime concern in oil and gas internal pipelines. Often, these types of failure have a great impact on the safety and environmental matters and can cause severe financial consequences to the operator. Chemical inhibitors have been used to provide effective protection for the asset against both localised corrosion and general corrosion. In order to develop superior localised corrosion inhibitors a better understanding of the mechanisms of the action and interaction of pitting and the film are required. An extensive study on the inhibition of pitting corrosion of carbon steel X65 in sweet and sour conditions has been carried out. In this study, a laboratory methodology using in-situ monitoring and post-test surface analysis techniques has been developed to investigate pitting mechanisms due to localised breakdown of films formed in sweet and sour environments.

Tesfaalem Gebremedhin Haile, Sankara Papavinasam, Timothy Zintel - A model was previously developed to predict internal pitting corrosion of oil and gas pipelines. The model considers the influence of temperature, total pressure, H2S partial pressure, CO2 partial pressure, the concentrations of sulphide, bicarbonate and chloride ions and the production rates of oil, gas, water, and solids. The model was based on experiments carried out in the laboratory at high pressure and high temperature under the operating conditions of the oil and gas pipelines and was validated by field trials and using field data. The model accounts for the statistical nature of pitting corrosion. Recently a microbiologically influenced corrosion (MIC) risk model has been developed and merged with the internal pitting corrosion model so that the integrated model predicts the optimized pitting corrosion rate due to both non-MIC and MIC activities.  Twenty years field data was collected from 19 pipe sections o

Mon. 10:25 - 10:50am Orange County Convention Center - S320 D Symposia: Corrosion in Nuclear Systems Electrochemical Studies of the Effect of Solution Impurities on Stress Corrosion Cracking of Austeni
Florent Bocher - There has been a recent growing interest in studying stress corrosion cracking (SCC) of stainless steels in pressurized water reactor (PWR). This is because austenitic stainless steels have long been accepted as being far less susceptible to SCC in PWR primary water than in boiling water reactor. However, utilities are becoming more concerned because over 130 SCC events have been reported since the eighties in PWR primary water. As a result, SCC of stainless steel in primary water of PWR has been classified as a high priority issue. The objectives of this program are: (1) to measure the effect of unusual solution chemistries (e.g. chloride, boric acid, oxygen concentrations) in primary water on the electrochemical properties of austenitic stainless steels, (2) to measure the effect of those compounds on the semiconductor properties of the passive film, (3) to assess the impact of applied potential on crack initiation and growth, and (4) to correlate the changes in

Jonathan Ukpai, Xinming Hu, Anne Neville, Richard Barker - A method based on count rate of measured Acoustic Emission (AE) signals has been implemented to investigate flow-induced corrosion and erosion-corrosion of X65 carbon steel. The specimen’s corrosion behaviour under submerged impingement jet (SIJ) in saturated CO2 oilfield process brine at constant temperature of 50oC was assessed for different flow velocities (7, 10, 15 m/s) without sand for flow-induced corrosion and with sand (50, 200, 500 mg/l) for erosion-corrosion. The AE signals’ count rate during each test was measured and analysed simultaneously with the corrosion rate from linear polarization resistance (LPR). The results show a good correlation between AE count rate and corrosion rate in each test; and that AE count rate increases with increase in corrosion rate as flow velocity is increased for flow-induced corrosion as well as increase in sand loading for erosion-corrosion which is an indication that flow-induce

Stefanie Asher, Andrew Wasson, Paul Russ - Mercury is a naturally occurring component present in varying concentrations in natural gas fields all over the world. Liquid metal embrittlement (LME) involves penetration of a liquid metal into a solid metal that leads to brittle fracture. In assessing the design of a production facility, a test program was established to evaluate the susceptibility of various metallic materials to LME by mercury. The susceptibilities of the alloys were determined using: 1) slow strain rate testing (SSRT) in mercury for screening and 2) subsequent fitness for service testing based on constant load testing (4-point bending) in a simulated service environment. Materials tested included duplex 2205, alloy 625, Alloy 400, 316L stainless, MP35N, Al5083 aluminum alloy and welded alloy 625. Results from these tests indicate that Alloy 400 and Al5083 showed significant LME susceptibility with an average time-to-failure ratio of 0.60 during slow strain rate scree

Ikechukwu Ivonye, Anne Neville, Xinming Hu - ABSTRACT Corrosion study of the inhibition properties of Monoethylene glycol (MEG) in acid gas corrosion of wet gas pipeline (carbon steel) was performed. MEG is a thermodynamic hydrate preventer use in the stop hydrate formation in gas pipelines. The quest for energy encourages more offshore gas development and operation. The integrity of the entire pipeline for the transportation of gas from source to process facilities onshore is very important. With the conditions obtainable in the transportation of this gas severe corrosion can occur on the pipeline without proper inhibition by corrosion inhibitors or other corrosion method. This paper describes the efforts in preventing the corrosion of the gas pipeline in the presence of MEG using commercially available corrosion inhibitors and discusses the corrosion inhibition mechanisms. The effect of under dosing of the inhibitor is also highlighted using surface analysis techniques. The paper

Hua Guan - Siliceous scaling deposition from geothermal brine are recognised as detrimental to the smooth operation of steam generation and injection facilities, the control of such deposition is costy and less well understood. Scales normally encountered in geothermal well are often different from the conventional cases. Silica (amorphous and colloidal) and poor crystallised metal silicates are the most common scale types in geothermal applications. There are a number of ways to control this types of scaling, including both engineering (e.g. maintain pressure and temperature) and chemical means (e.g. controlled precipitation and inhibition). This paper will focus on preventative techniques by the use of chemical inhibitors. However, currently there are no standard or generally accepted laboratory test methods to study this type of fouling problems. Using a low pressure test method and testing apparatus, we are able to rank the scaling inhibition performance of several generic chem

Daham Gunawardana, John Walmsley, Anders Holmen, De Chen, Hilde Venvik - Abstract: Ni-based industrial alloy samples (Alloy 601) were subjected to different oxidation conditions, followed by exposure to a high carbon activity gaseous mixture containing 10% CO in Ar at 550 ºC in order to reveal factors critical to the initial carbon formation. Fresh and treated alloy samples were studied via optical microscopy, scanning electron microscopy (SEM), auger depth-profile analysis, transmission electron microscopy (TEM), energy dispersive microscopy (EDS) and electron probe micro-analysis. The results show that the extent of carbon formation is dependent on the oxidation parameters, since these affect both the composition and the structure of the 20-60 nm thick oxide layer formed. A high oxygen partial pressure during the oxidation step appears to promote the inclusion of Ni or Fe species in the oxide layer, which subsequently reduce and catalyze the growth of carbon filaments.

Chong Li, Fang Cao, Sanket Desai, Shiun Ling, Jorge Pacheco - Carbon steel corrosion in the presence of CO2 and H2S (referred to as CO2/H2S corrosion or sour corrosion) is a concern in the oil and gas industry. Chloride is typically present in the production fluid, but can range from part per million (ppm) for condensed water to tens of percent (%) for produced water. Currently there is a lack of understanding on the effect of chloride and/or salinity on sour corrosion. To gain this understanding, high pressure autoclave laboratory testing has been carried out to study the effect of sodium chloride concentration on carbon steel sour corrosion. In these experiments, weight loss corrosion rates were measured. Corrosion product scales were characterized using scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), x-ray diffraction (XRD), and transmission electron microscopy (TEM). Localized/pitting corrosion was also evaluated by scanning the corroded coupon surface

Sonja Richter, Ragnheidur Thorarinsdottir - Low-temperature geothermal water in Iceland generally has high pH, low conductivity, and is oxygen free, resulting in negligible corrosion. However, with ingress of oxygen, due to contamination of fresh water as an example, the corrosion rate can increase significantly. In order to establish methods of monitoring corrosion under these conditions, several corrosion monitoring methods were tested in two locations in Reykjavik, Iceland and one location in Keflavik, Iceland. It was found that electrochemical tests tended to overestimate the corrosion rate due to the slow polarization behavior of the system while weight loss techniques required too long of an exposure to provide real-time information; although they gave reliable historical data on the corrosion that had accumulated over the previous three, six or twelve month time. A differential ER-probe proved to be the most promising measurement technique for these conditions. The analysis o

Richard Barker, Xinming Hu, Susan Cushnaghan, Anne Neville - Over the last decade, significant advancements in chemical inhibition have enabled operators to use carbon steel pipework in oil and gas facilities where sand production is a concern. The ability of these chemicals to reduce both the electrochemical corrosion reactions and the mechanical damage attributed to particle impingement is well documented. This paper presents a review of five commercially available oilfield corrosion inhibitors (four standard corrosion inhibitors and one high shear inhibitor) in an effort to establish their performance in erosion-corrosion environments. Experiments were conducted at 45°C using a submerged impinging jet (SIJ) in CO2-saturated conditions with a fluid velocity of 14 m/s and a sand loading of 500 mg/L.

Pouria Ghods, Victor Paddila, Akram Alfantazi - The galvanized steel is generally used in mechanically stabilized walls to reinforce the soil because of its high corrosion resistance compared to carbon steel and also its cost effectiveness compared to stainless steel. In the galvanized steel reinforcement, steel is protected against corrosion by a tiny layer of zinc cover with the thickness of 20-40 m. The corrosion of galvanized steel in soil consists of three stages. In the first stage of corrosion, the zinc layer dissolves into soil pore solution. When the underlying rebar is exposed to the soil environment in the second stage of corrosion, a galvanic corrosion cell forms between the zinc and steel that limits the corrosion of steel reinforcement. The carbon steel reinforcement starts corroding after the depletion of the zinc layer in the last stage of corrosion. In this work, the three stages of galvanized steel corrosion were modeled using the finite element method and a nume

Frank Cheng - High density polyethylene (HDPE) is a polyolefin thermoplastic material with a favorite property combination enabling it to be used widely in various industrial applications, such as the enhanced oil recovery (EOR) process. The HDPE pipeline networks transport the alkali surfactant polymer (ASP) fluids to injection wells and the produced fluids (combination of crude oil, water and residual ASP fluids) to a central processing facility. However, HDPE pipes suffer from serious environmentally stress cracking (ESC). To date, there has been no relevant research conducted to determine the ESC resistance of HDPE pipe material in ASP service. In this work, the stress-strain behavior and mechanical properties of three types of HDPE material were measured after one month of soaking in 0.5wt% ASP fluid (pH 14) under various temperatures and pressures.

Sigrun Karlsdottir, Kolbrun Ragnarsdottir, Ingolfur Thorbjornsson, Thorsteinn Sigmarsson - The IDDP-1 well in the Krafla geothermal field in Iceland is the first well in the Icelandic deep drilling project (IDDP). The superheated steam from the well is extremely hot and presently shows temperatures up to 450°C at a pressure over 120 bar at the wellhead. The IDDP-1 steam contains acid gas (HCl and HF) and is highly corrosive when it condenses. Different pilot studies were setup to investigate the usability of the superheated steam for power production. This included a wet scrubbing experiment, where the wet scrubbing of the steam was performed at 10 bar and 180°C. The spraying chamber of the wet scrubbing system was made out of Inconel 625 material and the mixing zone of 254 SMO, other parts of the system such as steam and moisture separators and steam pipelines (situated before and after the mixing zone) were carbon steel materials. The results showed that the acid gas in the steam

Margit Weltschev, Anka Kohl - Resistance to oxidative degradation by nitric acid is one of the properties selected for the comparison of polyethylene grades in a European standard on suitability proof for alternative plastic resins used for packagings and intermediate bulk containers (IBCs) for the transport of dangerous goods. Measurements of IR absorption spectra of microtome slices cut from the wall of jerricans, which were pre-storage with 55 % and 70 % nitric acid for 21 and 28 days at 40 °C, with the FTIR spectrometer showed the changes in the structure of the pol-yethylene grades. The intensities of IR bands at 1565 cm 1 ( NO2), 1630 cm 1 ( C=C) and 1654 cm 1 ( O NO2) increased with rising treatment time with 55 % nitric acid as a result of the oxidative damage by the nitric acid. Therefore values of absorbance were used to compare the grades due to their resistance to oxidative degradation. The high increase of the absorbance of the ( C=C) band in the region 1630 1690 cm 1 i

Mon. 11:15 - 11:40am Orange County Convention Center - S320 E Symposia: High-Temperature Issues and Materials for the Process Industry Hot Corrosion Behavior of Protective Oxide Scales with Sodium Chloride in Chlorine Gas Environment
Syed Khalid Hasan - Sodium chloride (NaCl) is one of the prominent hot corrosion inducing constituents of salt deposits that accumulate on the alloy surface in the field. In a marine environment NaCl is ingested into a gas turbine as an aerosol of sea salt along with intake air. At high temperatures, conventional alloys are severely attacked by NaCl and protective oxide scales like Cr2O3, Al2O3 and NiO invariably deteriorate. This paper deals with the high temperature reaction kinetics of such metal oxides with NaCl in a Cl2 gas environment at atmospheric pressure. The kinetics of the reactions between NaCl and metal oxides were studied by monitoring them by thermo-gravimetric analysis. Reaction products were identified by XRD analysis and SEM studies. Water soluble metal species in the mixture were estimated with the help of atomic absorption spectroscopy and pH of aqueous solution was taken into account to establish the reaction mechanism. The result showed that the mixed oxide of

Fraser King, Peter Robinson, Claire Watson, Jenny Burrow, Cristiano Padovani - A model has been developed to assess the potential for the atmospheric corrosion behaviour of stainless steel LILW containers in storage and during the operational phase of a geological disposal facility (GDF) in the UK.  The model, Atmospheric Corrosion of Stainless Steel in Stores (ACSIS), can be used to predict the extent of localised corrosion and stress corrosion cracking (SCC) and, equally importantly, to inform store designers and operators how to avoid atmospheric corrosion through appropriate control of environmental conditions. The model accounts for the initiation and propagation of localised corrosion (either pitting or crevice corrosion) and SCC of austenitic or duplex stainless steel containers as a result of the deliquescence of surface salt contaminants.  The code first characterizes the time-dependent nature of the corrosive environment in terms of the duration of, and interval between,

Francisco Presuel-Moreno, Hariharan Balasubramanian, Yu-You Wu - Reinforced concrete pipes are frequently use as drainage pipes. Corrosion has been found on culverts at locations close to the ocean. However, modest or no corrosion of RCPs have been observed on RCP placed in soils with known high chloride concentration and high moisture content. It is frequently assumed that this is due to oxygen concentration limitations. The current research present preliminary results of an investigation being carried out to better understand and characterize on-going corrosion on RCP exposed to relevant conditions (high humidity conditions and/or to low oxygen concentration)

Juan Genesca Llongueras - The effect of turbulent flow conditions on the kinetics and mechanism of some relevant corrosion processes is studied and analyzed: CO2/H2S corrosion, inhibitors evaluation and electrochemical behavior of cathodic protection galvanic anodes. In all this cases, the rotating cylinder electrode, RCE, becomes a useful and valuable tool to study the mass transfer process involved which typically is the rate determining step of corrosion mechanism. It was found that under turbulent flow conditions, the corrosion rate linearly increased as the RCE’s rotation rate also increased and the overall electrochemical corrosion process was influenced by the oxygen mass transfer process on the cathodic kinetics.

Sytze Huizinga, Ahmed Al-Harthi, Jan deJong - A laboratory testing program was carried out for an oil & gas project in the Middle East to verify ISO15156/NACE MR0175 limits for sour service cracking resistance of UNS S31603 in oil & gas production environments. The testing program started with the validation of the ISO 15156 limit (part 3,Table A.2 - 1 bar H2S, 60C) for UNS S31603. Ripple Slow Strain Rate (RSRT) tests were conducted at a third party lab as per NACE Corrosion 1997, P97058. The test was performed on duplicate specimens of UNS S31603 stainless steel material to evaluate the cracking susceptibility and impact of small amounts of plastic strain when exposed to different sour environments. The potential test matrix included nine (9) sour environments and prescribed the testing sequence logic that indicated the order in which the testing would be performed depending on test results.

Cameron Mackenzie, Michael Lane, David Blumer, Mohsen Achour, Catherine Rowley-Williams, Fiona Mackay - Following our preceding papers on the theoretical underpinnings and laboratory development of the micelle detection method, this paper will describe a variety of case studies where it has been applied to systems to investigate the field-relevant functional dose of corrosion inhibitor. The relationship between the critical micelle concentration of surfactant-based corrosion inhibitors and inhibitory efficacy has been recognised since the early 1980's. By coupling these academic findings with recent advances in analytical hardware and chemical markers which provide the ability to detect micelles rapidly within oilfield brines, useful information can be accessed in field conditions related to the physical action of the inhibitor rather than a chemical residual. The absence of micelles can be used to diagnose an under-dosed system in situ or the enumeration of present micelles can be

Samar Saha - Abstract: The presence of hydrogen sulfide (H2S) in the oil and gas exploration and production process poses hydrogen embrittlement and sulfide stress cracking (SSC) concerns for high-strength, low-alloy (HSLA) steels commonly used in Oil Country Tubular Goods. This paper presents Critical Stress Intensity Factor (KISSC) data on two heats of standard mill-produced C110 casing (micro alloyed 4130 type steel). Double Cantilevered Beam (DCB) samples from this material were tested in NACE A solution to the requirements of NACE Standard TMO177 Method D in various sour environments (3.5%, 7.0%, 14%, 22.0%, 50%, and 100% H2S) under a range of applied loads (wedges 20, 25, 30, 35, and 40 mils thick ). A simplified approach is presented to derive and develop DCB test variables, an acceptance range for KISSC, and KISSC compliance for C110 material exposed to H2S environments that are not covered by the current NACE Standard

Masahiko Tachibana, Kazushige Ishida, Yoichi Wada, Ryosuke Shimizu, Nobuyuki Ota - Hydrogen peroxide (H2O2) is the most important oxidant to determine the corrosive environment of boiling water reactors (BWRs). Since H2O2 is unstable at high temperature and electrochemical measurement in high purity water is difficult, H2O2 polarization characteristics in the BWR environment are not well known especially at less than 10ppb. Cathodic polarization curves of the H2O2 reduction reaction were measured in simulated BWR conditions at 553K over the H2O2 concentration range of 1 to 1000ppb. The polytetrafluoroethylene chamber was set in a circulating autoclave to reduce decomposition of H2O2, and the potential step method developed for measurements under the BWR conditions was used to measure H2O2 polarization curves. The exchange current density of H2O2 (0.28μA・cm^-2) was more than tenfold higher than that of O2(1.5x10-5μA・cm^-2) at 10ppb. And, the Tafel constant (bc) of H2O2 (0.006) was 1/

Mon. 1 - 1:25pm Orange County Convention Center - S330 D Symposia: Fluid-Induced Degradation—Corrosion, Erosion, and Their Interactions A New Improved Model for Phase Wetting Prediction in Oil-Water Two Phase Flow
Sonja Richter, Xuanping Tang, Srdjan Nesic - Internal corrosion is one of the most common problems within the transportation pipelines of the oil and gas industry. Water wetting is an important issue in the prediction of internal CO2/H2S corrosion in mild steel pipelines, since the water will not corrode the steel unless it is in a direct contact with it. The water wetting is affected by water chemistry, flow regime, pipe orientation, water cut, and oil properties etc. Cai et al. (2011) proposed a mechanistic model to predict phase wetting in oil-water two-phase flow. Good agreement was achieved between experimental results and the predictions, but only for a model oil. For crude oils, the model overpredicted water wetting leading to overestimation of corrosion in the system. A new mechanistic phase wetting prediction model is proposed. In addition to considering the energy balance between the turbulence and the surface tension, the new model includes the effect of the surface wetta

The pipelines as electrochemical cells include physical characteristics (working electrode), soil conditions and environment surrounding the metallic structure (electrolyte and interface) that are not only a function of position but time. Corrosion as time dependent threat is a magnitude directly influenced by the dynamic parameters, such as the water content and drainage properties in the soils.

Helmuth Sarmiento Klapper - Geothermal drilling conditions are severe in terms of corrosion. Highly saline fluids and corrosive gases such as H2S and CO2 are typical of deep hydrothermal aquifers. The combination of this complex chemistry at high temperatures and drilling-related cyclical mechanical stresses significantly affect the performance of metallic materials. Consequently, the use of corrosion resistant alloys with appropriate mechanical properties, such as high strength stainless steels and precipitation hardening nickel-base alloys, is required for geothermal applications. As geothermal wells increase in depth and complexity, so too do temperature and cyclic bending loads increase, which in turn raise material qualification requirements. Measurements of localized corrosion resistance and corrosion fatigue strength are valuable qualification tests to ensure a safe and reliable operation. This paper outlines some recent approaches for material testing at conditions observed

Behzad Bavarian - Commercially available inhibitors were successfully investigated for their effectiveness in reducing the corrosion susceptibility of the turbo expander and steam/gas turbine industry alloys. However, due to the fact that the power generating system is complex and consists of a multi-alloy system, the investigation was expanded to study the corrosion behavior and stress corrosion susceptibility of other alloys such as, copper, brass (C36600 (38% Zn), Eco-brass (21% Zn), and red brass (8% Zn), nickel plated-copper and titanium alloys (grade 5 and grade 23) in the presence of these inhibitors. Electrochemical behavior (cyclic polarization and EIS) of these alloys in a 200 ppm Cl- solutions + different percentages of inhibitor showed significant improvement in passivity, breakdown potentials, and their critical pitting temperature.

Seong-Mo Son, Chul-Hwan Lee, Chung-Seo Park -      The internal coating of ship's cargo tanks is essential to protect steel surfaces against corrosion and to avoid contamination. Inorganic ethyl zinc silicate coatings are one of the successful solutions for corrosion protection, but there are several disadvantage in this coating system. It is easily contaminated in poros structure and has limitation in recommended film thickness caused by low crack resistance. In spite of these drawbacks, inorganic ethyl zinc silicate coatings are generally used for specified chemical products carriers because of its excellent corrision resistance.      In this study, crack resistance was evaluated and enhanced for the increase of maximum allowable dry film thickness. With this increase, low crack resistance can be improved and prevent excessive coating thickness.

Yougui Zheng, Bruce Brown, Srdjan Nesic - The internal corrosion of carbon steel in the presence of hydrogen sulfide (H2S) represents a significant problem in oil production and natural gas treatment facilities, but the true mechanism of H2S corrosion is still not clear. This lack of knowledge represents a critical problem for the prevention and/or control of corrosion related to the presence of aqueous H2S. To investigate H2S corrosion mechanisms using observations during the initial contact of [H2S]aq and mild steel, short term corrosion tests (1-2hr) were conducted in 1 wt.% NaCl solution at the different pH (pH2 to pH5), different temperature (30oC to 80oC) under various H2S/N2 concentrations (0-10%) and flow rate conditions using an X65 mild steel rotating cylinder electrode.

In the presence of the scale and bacteria, corrosion can be aggravated. A combined corrosion inhibitor (CCI-2) is developed, which provides corrosion/scale inhibition and mitigates microbially induced corrosion. A scale inhibitor with great performance and tolerance to high calcium cation is incorporated in CCI-2. Autoclave test is conducted using synthetic brine of medium total dissolved solids with a gas phase of 520 kPa H2S, 350 kPa CO2, and 735 kPa N2. CCI-2 reduces corrosion rate by 96%. Biocide test shows that CCI-2 can kill acid producing bacteria (APB). CCI-2 is successfully applied in the field gas lines with high content of CO2 and H2S.

Sreya Dutta, Satish Mohapatra, Kevin Coscia -     With increasing demands for renewable energy to meet electricity needs, the need for alternative energy is growing rapidly. Concentrating Solar Power (CSP) provides an efficient way of converting solar energy to electricity and heat. Molten salts provide excellent high temperature media for thermal storage and heat transfer at temperatures above 500°C. High temperature and the corrosive nature of salt mixtures aggravate corrosion in these molten salt-based power plants. Using expensive high alloy materials for piping in the solar field requires an immense capital cost, so it is beneficial to use less-expensive materials while still being able to circulate the fluid at high temperatures with minimal corrosion. Molten alkali nitrate (NaNO₃-, KNO₃- based) salts cause extensive corrosion of stainless steel at temperatures above 500°C and with chlorides (combination of NaCl, KCl, ZnCl₂, LiCl, AlCl₃, MgCl₂, and CaCl₂), though the operati

Kingsley Lau, Mario Paredes - Corrosion protection of post-tensioned (PT) steel strand consisted of embedding the strand in grout material (with highly alkaline pore water) within a high density polyethylene (HDPE) duct. The highly alkaline environment ideally would promote steel passivation and the HDPE duct would prevent intrusion of external moisture and aggressive chemical species into the tendon. However, corrosion development of PT tendons has occurred. In early tendon failures in Florida, corrosion had in part been attributed to void space formation in the grout due to bleed water accumulation or improper grouting procedures. Subsequently, new grout material requirements for PT systems specify minimal bleed water formation. Yet recently, corrosion problems have occurred with these new formulation grouts as well.   Some of the first PT bridges to be constructed in Florida with the low bleed water grouts were recently found to have severe material deficiencies in the grout of p

The tests were done following a failure analysis of a broken liner from the well. The failure analysis revealed that the liner was severely corroded and parts of it situated at 1600 m depth had experienced hydrogen damage in the form of hydrogen embrittlement. The corrosion tests were done in the down-hole geothermal environment. Two identical test racks were made and exposed to the down-hole geothermal environment for two different periods of time (4 days and 14 days).  The following materials were tested: API-K55, TN-95, 13Cr, SAF 2507, 254 SMO, Sanicro 28 and SM 2550. The corrosion resistance of the alloys that were tested was measured and elongation at brake was measured to evaluate the susceptibility of the materials to hydrogen damage. The chemical composition and structure of the corrosion scales that formed on the samples during testing were an

Megan Dahl, Sarah Philo, Glenn Edgemon - Pipeline Hazardous Material Safety Administration (PHMSA) regulators do not require cathodically protected pipelines located within nuclear facilities to be assessed by External Corrosion Direct Assessment (ECDA) or any other method used to ensure integrity.  A case study is presented using the direct assessment process on pipelines in a nuclear environment.  It is essential to remove the threat of external corrosion in order to prevent nuclear contamination of the public and environment.  It was determined that the nuclear contamination threat requires sufficient historical and on-going probe/coupon monitoring data, information about the condition of each coating layer, and an understanding of historic and current cathodic protection levels in order to anticipate where corrosion may be occurring.  There is therefore a need for a fully auditable and systematic process by which the external corrosion threat can be adequately assessed.  An app

Alex Nadezhdin, Scott McQuat - The engineered wood industry involves production processes which are essentially dry in nature. Although moisture and condensation are present in steps such as flaking, drying, blending, and pressing of the wood furnish, the effect of bulk corrosion is mostly trivial and/or non-critical to the equipment. Instead, the secondary effects of corrosion such as wear and cavitation enhancement, or the hydrogen embrittlement of the high strength fasteners may have expensive consequences in terms of reliability of the overall process. The article presents typical examples of big impact caused by little, sometimes invisible, corrosion in the background.

Takao Ohtsu, Masazumi Miyazawa - There have been many studies of high temperature corrosion in process streams. The corrosion phenomena and the conditions of occurrence differ according to the material involved and environmental factors that affect its behavior. However, the basic mechanism of high temperature corrosion has been clarified by such investigations. Nevertheless, high temperature corrosion damage in chemical equipment may differ from typical examples in other applications because the corrosion mechanism and the damage morphology are attributable to the influence of organic products in the service environment. This paper discusses the investigation and measurement of high temperature corrosion of Alloy 600 and Alloy 800 heat exchanger tubing in organic chemical processing streams.

Iozsef Palencsar, Egil Gulbrandsen, Kateřina Kosorú - Corrosion inhibition as the choice for mitigating corrosion of carbon steel in oil and gas production is increasingly difficult for fields with high temperature conditions. In addition, laboratory testing of intrinsic inhibitor performance at high temperatures is a challenge in itself. Efforts aimed at both improving evaluation methodology and generating experimental data are therefore valuable. Within the framework of a Joint Industry Project the authors addressed issues highly relevant from this perspective, such as inhibitor performance, mechanistic aspects and test methodology development. This contribution presents some of the most important findings from this project.

Chul-Hwan Lee, Ki-Hoon Han - Organic coatings have been widely used to protect steels and other metals in corrosive environment due to their good physical, chemical performance and low cost. Many kinds of organic coatings have been also applied to protect ship in various corrosion environments. Especially, epoxy coating systems among various organic coatings have been mainly used to protect water ballast tank of ship from corrosion. Since the introduction of aquatic nuisance species via ship’s ballast water has raised detrimental ecological issues, numerous water ballast treatment systems that may block inflow of aquatic species are presently being studied. However, by using these treatment technologies, there have been concerns that they may have some adverse effects on the performance of coating system for ship’s ballast tank. Because coating performance especially for water ballast tank is important factor to determine ship’s lifetime, it is essential to evaluate coating performa

Homero Castaneda Lopez, Britt Minch, Ben Faber - In this work we selected different conditions to characterize the mechanisms existed at the interface level of the films used as rust preventatives for steel substrates. Rust preventatives were applied to steel samples and characterized by advanced electrochemical and standard method. Electrochemical Impedance Spectroscopy (EIS) has been used as a prime technique to quantify and characterize the mechanisms existing when corrosive environments are exposed to metal/film interfaces. This work includes the methodology to use advance electrochemical technique set up, such as EIS to qualitatively characterize films formed to produce corrosion barriers. The proposed technical method is a demonstration for different thin film samples that can guide the path forward for the most suitable selection of the corrosion preventative film, for steel substrate exposed in different environments.

Bruce Wiersma, Karthik Subramanian, Adam Hansen, John Mickalonis - Radioactive liquid waste has been stored in underground carbon steel tanks for nearly 60 years at the Savannah River Site.  The site is currently in the process of removing the waste from these tanks in order to place it into a vitrified, stable state for longer term storage.  The last stage in the removal sequence is a chemical cleaning step that breaks up an dissolves the metal oxide solids that cannot be easily pumped out of the tank.  Oxalic acid (OA) will be used to chemically clean the tank after waste retrieval is completed.  The waste tanks at SRS were constructed from carbon steel materials and thus are vulnerable to corrosion in acidic media.  In addition to structural impacts, the influence of corrosion on the hydrogen generated during the process must be assessed.  Electrochemical and coupon immersion tests were performed to investigate the corrosion mechanism at anticipated process conditions.  The test

Based on the field indirect inspection results, it was concluded that over-bends are usually prone to localized pitting corrosion but the root-cause of this phenomena is not clear and is yet to be investigated. In this study the effect of crude API density, water to oil flow-rate ratio (water-cut) as well as pipeline internal diameter, inclination angle and total flow rate on the risk for localized pitting corrosion will be investigated based on numerical simulation of the flow. The multiphase flow pattern inside the pipeline for different sets of operational conditions will be studied and sites susceptible to water and solids accumulation based on the obtaine

Jeffrey Xie, Derek Mitchell, Bill Courtney, Katy Yazdanfar - The shaft of a rotatory valve for polyethylene pellet service fractured. In order to understand the fracture mechanism and mitigate future fracture failures, the fracture was investigated in term of metallurgical, compositional and morphological characteristics on the fracture surface and cross-sections of the shaft. The characterization determined that the fracture of the rotatory valve shaft was the result of rotational bending fatigue. Fatigue cracks were initiated from multiple locations, leading to the formation of multiple ratchet marks around the shaft circumference. The torsional stress caused the ratchet marks to be roughly 45° to the fracture plane. The stress was high at the time of the fracture, inducing an overload zone to be roughly 60% of the entire fracture surface. The concave curvature of the fracture surface indicated stress concentration at the location of fracture. Microstructural analysis revealed tha

Simona Regenspurg, Elvira Feldbusch - SHighly saline geothermal fluid is produced from a Permian sandstone reservoir (4.4 km depth; 150 °C) at the geothermal in situ laboratory in Groß Schönebeck (North German Basin). The brine is of Na-Ca-Cl type and contains about 265 g/L total dissolved solids. The gas phase is predominantly marked by N2 (85 %) and CH4 (14 %) and the volume ratio of liquid to gas is, at amospheric conditions, about 1:1. During the production of the fluid an intensive monitoring of the different phases of the fluid was performed in 2011 and 2012. An on-line gas monitoring allowed to measure the amount of N2, CH4, H2, CO2, O2, He, and H2S in the gas flux, which was seperated from the fluid in the above ground installations.

Kingsley Lau, Juan Rafols, Ivan Lasa, Mario Paredes - Grout in failed post-tensioned tendons in Florida with varying extent of segregation was characterized as having different properties and chemistry which may promote corrosion activity. Although early repair procedures have been implemented in a bridge to remove the most severely segregated grout from some locations of the deficient tendons, some concerns on future corrosion progression after initial repairs have been raised.   There was interest in gauging the extent to which corrosion may develop for repaired PT systems in which void spaces have been re-grouted with dissimilar grouting materials and where differences in pore water chemistry may contribute to corrosion development. This study aims to determine the extent to which corrosion of strand in dissimilar grout materials can form. The research was to identify corrosion mechanisms that may occur in tendons with ideal and deficient/partial repair conditions.

Tomohiko Omura, Atsushi Souma, Taro Ohe, Hisashi Amaya, Masakatsu Ueda - Environmental cracking susceptibility of low alloy steel OCTG (T95, C110 and P110) in high H2S partial pressures was investigated by 4 point bend tests in autoclaves. The H2S pressures and testing temperatures were varied from 10 bar – 24oC to 100 bar – 150oC. Sour grades (T95 and C110) showed no macro-crack in all tested conditions. Small localized corrosion occurred in higher H2S with higher temperature conditions, but did not propagate after long term (3 months) immersion tests. It was concluded that the sour grades tested in this research can be used up to 100 bar H2S - 150oC with no environmental cracking. P110 suffered from SSC below 65oC at 10 bar H2S. The results correspond to the temperature limit of P110 defined in NACE MR0175 / ISO 15156-2. Mechanisms of cracking susceptibility were discussed from the viewpoints of corrosion rates and morphologies of corrosion products on the steel surface.

Mon. 1:50 - 2:15pm Orange County Convention Center - S320 F Symposia: Corrosion in Pulp, Paper, and Biomass Conversion Comparing the methodologies in ASTM G198; is there an easy way out?
Samuel Zelinka - ASTM G198, Standard test method for determining the relative corrosion performance of driven fasteners in contact with treated wood, was accepted by consensus and published in 2011. The method gives two different exposure conditions for determining fastener corrosion performance in treated wood. The first method places the wood and embedded fasteners in a chamber at 95% RH, 32°C for 120 days. The second method involves a cyclic fog, with 48 hours of fog followed by 72 h of “dry” for 120 days. The corrosion rate of embedded metals is an extremely sensitive function of the wood moisture content. While the wood moisture content is well defined, and fixed, in the constant RH test, the moisture content will fluctuate and there will be moisture gradients in the cyclic fog test. As a result, the fasteners in the cyclic fog test experience non-uniform and constantly changing conditions, which may be more or less challenging than the constant conditions test. This paper pres

Tim Whited, Robin Tems, Xianming (Andy) YU - Soil-side corrosion of the bottom plates of above ground crude oil storage tanks is a major corrosion challenge in the oil & gas industry, especially when these tanks are constructed on oiled-sand pads. Severe corrosion has been identified on tank bottoms at a crude oil tank farm in the Arabian Peninsula. Corrosion led to the costly replacement of bottom plates. The soil-side surfaces of the bottom plates were designed to be protected by a shallow anode impressed current cathodic protection (CP) system. The oily sand layer and air gaps under the bottom plates reduced CP effectiveness and resulted in severe corrosion. To reduce corrosion damage, volatile corrosion inhibitor (VCI) was injected into the air gap between the sand pad and the underside of the tank bottom during a scheduled maintenance outage. An electrical resistance (ER) probe corrosion monitoring system was also installed underneath the tank. Effectiveness of the VCI treatme

Giovanna Gabetta, Patrizia Fassina, Gazmend Hoxha, Alberto Pontarollo - The exploitation of fields with high H2S and/or CO2 content is nowadays of growing importance for oil companies. The presence of H2S and/or Sulphur in crude oil can be responsible for both general and localized corrosion. In application, users can combine experience with suggestions from standards and regulations. A good deal of knowledge is available to predict Corrosion Rate for CO2 containing hydrocarbons, but the effect of high pressure H2S is less known, also due to the difficulty of performing laboratory tests in such challenging conditions. Re-injection wells are for instance in contact with dry supercritical fluids, whose corrosion properties are not fully known.

Fletcher Surfactant and Colloid Group, Department of Chemistry, University of Hull, Hull, HU6 7RX, United Kingdom Organic corrosion inhibitors, such as the homologous series of alkylbenzyldimethylammonium chlorides (CnBDMAC), consist of a hydrophobic tail coupled to a hydrophilic headgroup and thus have surfactant functionality in addition to their corrosion inhibition action. They inhibit corrosion by adsorption to the steel-water interface to create a surface film which can act to slow the rate of corrosion by several orders of magnitude. The surfactant properties of these species can affect their efficacy as corrosion inhibitors in several ways. Firstly, they can adsorb competitively on “parasitic” surfaces such as sand which then decreases their adsorption at the steel-water surface and

Sunday Aribo, Michael Bryant, Xinming Hu, Anne Neville - Lean duplex stainless steels are becoming increasingly popular in the oilfield environments as a result of their attractive cost, good mechanical properties and relatively good corrosion resistance. One such application is in the production of carcasses of flexible pipes. For high sand production oilfields, the challenge has gone beyond mere corrosion resistance and should include erosion-corrosion resistance. During the production of carcasses, the materials is left in the cold worked condition in contrast to the solution treated condition required by NACE standard. The cold working of this alloy not only affects the surface features but also the subsurface/near-surface morphologies.

Merlin Bandeira, Rogaciano Maia Moreira, Oscar Mattos, toseli matos, ANDRE BESERRA, Sérgio Tavares, FABIO SANTOS, FABIO PIRES - Flexible pipes have been widely used in offshore applications for transportation of oil and gas. These structures are constructed with various layers of steel wires for structural reinforcement and several polymers layers to contain the internal bore fluid and protect the metallic components from the seawater. The carcass main function is to prevent collapse. Once the carcass can be exposed to external pressure on the inner liner, and the inner liner itself is not capable of carrying any particular external pressure and will therefore collapse if it is not supported on the inside. Thus, the carcass is installed to provide the inner liner with this support. Another way the inner liner is subject to external pressure is if the outer sheath is damage and sea water enters the annulus. If the pipe is unpressurised, the inner liner is subject to an external press

Florian Thebault, Anne-Sophie Bureau-Bayart, Laurent Delattre, Diana Koschel, Emmanuel Desdoit, Bertine Orlans-Joliet - NACE TM0177 Method D (DCB) test allows the determination of the critical stress intensity factor KISSC, below which the propagation of a sulfide stress crack in the material is stopped. For a given severity of the sour medium (pH, PH2S, T, [Cl-]…), KISSC is not a material constant since it depends for instance on the testing arm displacement. Recently, the Klimit concept was proposed to circumvent this issue. Klimit is a conservative KISSC value and would be more representative of the material corrosion resistance. For an accurate determination of Klimit it is necessary to know KIapplied, the KI value when the test starts. In the proposed revision of the NACE TM0177 standard, it is recommended to use the compliance of the DCB specimen and the calculated arm displacement value for the determination of KIapplied.

Yasuyoshi Tomoe - Inhibitor evaluation on a Cr bearing steel was carried out studying effective active ingredients of potential inhibitors and the beneficial effects of co-existence of small amount of liquid hydrocarbon which has been experienced for carbon steel. Because of the pressure lowering of a gas-condensate field, the gathering line temperature will be estimated to reach at nearly 150 oC in sweet corrosive conditions, the use of 13%Cr material is considered to be one option. However, the corrosion resistance of 13%Cr is known to deteriorate at about 125 oC and higher. It was vital to initiate to study potential inhibitor effectiveness for 13%Cr steel before the employment of the alloy for the particular lines. It was found that amines were not effective for 13%Cr steel but carboxilic acids showed some protection even at 150 oC. The addition of small anount of liquid hydrocarbons markedly increased the inhibitor performance.

The steam methane reformer is widely used in the oil industry to make hydrogen.  The development of super-alloys for high temperature service applications, e.g., nickel-iron-chromium alloys in wrought form (UNS N08810/N08811) for reformer outlet pigtails and header, became industry standard materials in the 1970s. Usually, even after the intended design life (100,000 hours), creep failure is less common in reformer outlet header compared to catalyst tubes. On-stream isolation by nipping is a commonly used maintenance practice in the event of reformer catalyst tube rupture to sustain H2 production. The failure of an outlet header can result not only in a plant shutdown, but will also take a longer time to be put back into service. In this paper, an

Abdul Hameed Al-Hashem, Hasan Tarish - An ultrasonically induced cavitation facility was used to study the cavitation corrosion behavior of UNS G1095 alloy in seawater. The work included measurements of free corrosion potentials, and mass loss in the presence and absence of cavitation.  The cavitation tests were made at a frequency of 20 KHz and at temperatures of 250C.  Cavitation conditions caused an active shift in the free corrosion potential for UNS G1095 alloy. Cavitation also increased the rate of mass loss of this alloy by several orders of magnitude with respect to stagnant conditions.  Another set of cavitation experiments was also carried out for this alloy in a nonconductive medium in order to distinguish between the mechanical and electrochemical factors that contribute to metal loss. Results indicated that the mechanical factor has an over riding role in metal loss of this alloy.  However, the electrochemical factor was concentrated on the mirogalvanic actitivities be

Joseph Fernandez, Alberto Sagues - High strength stainless steels are increasingly receiving consideration for prestressed concrete applications. While resistance of these materials to pitting corrosion is expected to be high, susceptibility to stress corrosion cracking (SCC) is a concern given the high levels of operating stress. There is very limited information on this issue at present for conditions relevant to service in concrete. Moreover, there is little availability of stainless steels strand material.  A preliminary evaluation of SCC performance was conducted with three alloys that had potential for commercial production: a common austenitic stainless steel (316L), an austenitic stainless steel with nickel substituted by manganese (XM29), and a duplex ferritic-austenitic alloy (2205), and that were available in strand wire form at strength levels >1.24 GPa. The alloys were evaluated bent to over the yield strength in neutral and in simulated concrete pore water solutions,

This paper details the findings of an evaluation of C125 performance in a variety of sour environments. C125 OCTG grades used in this study are from recently developed, proprietary grades. The SSC resistance was evaluated using TM 0177-Method D. The testing environments are in Region 2 and 3 as specified in NACE MR0175/ISO 15156. The SSC resistance of C125 was found to be more affected by H2S partial pressure than by pH. The SSC resistance and behavior of C125 in mild sour environments was observed to be very different from that in severe sour environments. Baseline

Amela Keserovic - Geothermal energy is considered one of a few alternatives ideal for replacing conventional polluting fossil fuels due to its cleanliness, consistency, reliability and the ability to provide baseload power. Despite the expensiveness of the project development, long-term costs of running a geothermal power station are extremely low. One of the major impacts on overall expenses has the constructional material. Due to the highly concentrated solutions of corrosive salts at high temperatures and pressures present in geothermal systems, a huge risk of equipment degradation and failure is present if inadequate and insufficient measures regarding the material selection are taken. This could not only lead to the curtailment in power plant energy production, but also, in the worst case, to the complete plant shutdown. Therefore it is of crucial importance to choose suitable materials which would in the same time withstand such aggressive environments and still be cost-effec

Sunder Ramachandran, Vladimir Jovancicevic, Greg Boyce, Christina Zeadow - As shallow onshore and offshore oil fields mature, new discoveries will occur in deeper reservoirs with higher temperatures and velocities that could present severe materials problems. There are several systems made of mild steel where the flow rates of gas, water and oil are high and the systems experience high velocity corrosion, such as electrical submersible pump (ESP) systems. For these systems a high shear corrosion inhibitor with high temperature stability is needed to prevent corrosion. Often the high shear corrosion inhibitors have a negative impact on produced water quality. In this paper, the development and field trial of a new high shear corrosion inhibitor is described. The new product demonstrates improved water quality relative to traditional corrosion inhibitors that work under high shear conditions up to 350◦F.

Ezeddin Busba, Alberto Sagues - Corrosion of steel in concrete causes cracking of the concrete cover C, when the metal loss reaches a critical penetration depth Xcrit. The value of Xcrit is important to formulate reliable models of the propagation stage. Corrosion of steel in concrete is commonly localized especially in high quality concrete structures. Localized corrosion can occur due to preexisting cracks in cover concrete, concrete joints or defects in steel coatings. It has been shown previously that the value of Xcrit increases as corrosion becomes more localized, but scarce data did not enable reasonable extrapolation to the case of small corroding lengths as may be encountered at the intersection of rebar with preexisting narrow cracks. This investigation determines Xcrit for cases of small corroding lengths (L), down to L/C=0.2, including tests with conditions overlapping those of the earlier work to provide the basis for a more precisely established relationship.

Nacéra Sabrina Meck, Tanmay Anand, Brian Chambers, Russell Kane, James Skogsberg - Modern, high-strength martensitic stainless steel (MSS) oil country tubular goods (OCTG) including modified 13Cr (95, 110 and 115 ksi grade) and 15Cr (125 ksi grade) grades are frequently considered as possible replacements to conventional 13Cr steel and duplex stainless steel tubulars for the completion of high-temperature, high-pressure (HTHP) wells. These alloys have demonstrated corrosion resistance in HTHP well conditions but are susceptible to environmentally assisted cracking (EAC) due to the interplay of depassivation due to chlorides and hydrogen uptake due to the presence of hydrogen sulfide. General caution and the need to perform extensive qualification tests on these alloys have historically limited their service in sour oil and gas production. Even though there is significant test data and published papers on modified 13Cr grades of MSS OCTG, particularly on 13Cr-5Ni-2Mo materials, major

After 25 years of service, many of the concrete tanks and other structures at a wastewater treatment plant in Arizona are experiencing corrosion of embedded reinforcing steel. An in-depth assessment of a tower trickling filter was performed to determine the cause and extent of corrosion-related deterioration and develop appropriate repair and corrosion control strategies. Non-destructive evaluation techniques used for the assessment included half-cell potential, corrosion rate, and concrete cover measurements, as well as thorough visual and sounding surveys. Laboratory evaluation of extracted concrete cores included petrographic analysis, chloride content testing to obtain concentration profiles, and rapid chloride permeability testing. The assessment showed steel reinforcing corrosion was driven by residual chloride present

Todd Mintz, Xihua He, Roberto Pabalan, Yi-Ming Pan, Leonardo Caseres, Greg Oberson, Darrell Dunn - Some U.S. nuclear power plants are storing spent nuclear fuel in dry cask storage systems (DCSS). In many cases, the DCSS consists of a metal storage canister inside a concrete vault or overpack for radiation shielding. Most of the canisters are made out of austenitic stainless steel (SS), including UNS S30400 (304 SS), UNS S30403 (304L SS), and UNS S31603 (316L SS). The concrete vault or overpack is vented to the atmosphere for passive cooling, allowing interaction between the canister and the ambient environment. In coastal environments, airborne salts could deposit and accumulate on the surface of the canisters over time. Deliquescence of these salts in a humid environment could create a chloride-rich brine on the canister surface. This, in addition to the presence of residual tensile stresses, could make the canister susceptible to chloride induced stress corrosion cracking. The ob

Bill Amend, Jeffrey Yee - The Kawerau geothermal power generating station in New Zealand uses pH modification to mitigate scaling in flashed brine piping and injection wells. After less than 2 years of operation, significant metal loss was observed in various areas of the steel piping and pressure vessels. The metal loss was generally localized and most extreme in areas of high velocity and turbulence. Corrosion allowance was exceeded in as little as X months in localized areas. While root cause analyses and planning for alterations to key areas of the process continued, corrosion mitigation strategies that focused on localized use of corrosion resistant alloys were tested in localized areas of the plant piping and equipment. The strategies included localized application of: • Stainless steel or NiCrMo weld metal overlays • Application of stainless steel plates and platelets welded to corrosion-susceptible areas • NiCrMo alloys applied by thermal spraying (high velocity arc spraying

Ben Faber, Britt Minch, Pedro Velis, DAVE BOOTHE, Raymond Hsu, Gregory Moran, Frank Kroto III, Vic Stanislawcyzk - Waterborne acrylic-based systems for corrosion protection End-users are constantly seeking flexibility with corrosion protection in order to maximize productivity without compromising on performance. One of the drawbacks to current industry standard technologies is that the films left on the metal surface after application of the rust preventatives are waxy or oily. These waxy or oily films can be easily damaged and require special handling to provide maximum protection, but they have the advantage of being easily removed. In order to increase the productivity of the end-users, a dry-to-touch waterborne rust preventative was developed based on an acrylic resin. The film left by this acrylic-based rust preventative allows for more rigorous handling while maintaining ease of removal.

Sherman Kung, Lara Morello - Erosion corrosion is a common cause of failure in hydro-transport pipelines. While there have been extensive studies on the erosive nature of silica sand, very little work has been done examining and understanding the mitigation of the erosion-corrosion of metals in oil sand environments. This is a complex problem due to a number of factors such as the fluid properties, flow rate, sand size and shape, and sand loading. In this study, a transparent glass vessel with a rotating cage assembly was used to evaluate erosion corrosion. The transparent vessel allowed for observation of the distribution and flow characteristics of the sand under varying rotation rates. Commercial and field sand at a 0 to 20 % loading were examined in synthetic brine/oil mixtures at 40 to 80 °C. The erosion corrosion rates were quantified by weight loss measurements for both inhibited and uninhibited systems. The metal surfaces were examined using a high magnification microscope.

Marita Berndt - Service environments for piping used in geothermal applications are chemically and physically complex and typically aggressive. Cement mortar linings are applied to provide corrosion protection to steel pipes used for transportation of geothermal fluids. However, the linings are susceptible to deterioration and have a finite life. Research was undertaken to improve the durability of cementitious linings and thereby increase the service life of lined pipes. Samples of mortar were exposed to simulated hypersaline geothermal brine at elevated temperatures. The mortar mix proportions and chemistry were varied and the performance compared. Protective treatments to the mortar were also explored. This paper describes the results of preliminary testing and provides recommendations on improvements.

Alberto Sagues - Some instances of local corrosion of steel containment liners have taken place on the liner surface that is in contact with the external concrete shell. The corrosion has been associated with foreign material left at the steel-concrete interface, creating a region where passivity breakdown is promoted on the steel surface. Local corrosion is expected to have been aggravated by the formation of a macrocell with a large cathodic surface area provided by the rest of the liner surface and additional embedded reinforcement. A corrosion multiscale finite element model is used to aid in evaluating the relative importance of the parameters that determine the rate of local corrosion, and to improve long term performance forecasting. The model assumes Butler-Volmer kinetics for the corrosion reactions and includes transport terms for the species responsible for the cathodic reaction. System geometry accounts for spatial distribution of the liner and embedded reinforcement. V

Mon. 4:15 - 4:40pm Orange County Convention Center - S230 A Symposia: Assessment and Control of Reinforcement Corrosion in Concrete Structures Potential-Dependent Chloride Threshold in Reinforced Concrete Damage Prediction
Andrea Sanchez, Alberto Sagues - There is increasing evidence that chloride corrosion threshold increases when steel bar potentials are more cathodic than -200±50 mV (SCE). When corrosion starts at a given location, the potential drops and delays corrosion initiation of the passive steel in adjacent regions. Introduction of threshold dependence on potential (TDP) is needed for accurate forecasting, as neglecting that phenomenon can lead to erroneously high damage projections. A previous work incorporated TDP in a finite difference deterministic model of a partially submerged reinforced concrete column. Corrosion was assumed to start when the chloride corrosion threshold was reached in an active steel zone of a given size. The model served to demonstrate feasibility of the concept but damage prediction was found to be highly sensitive to the assumed corrosion activation zone size. As the number of nodes used for the model increased, resulting in smaller activation zones, the total p

Mon. 4:40 - 5:05pm Orange County Convention Center - S220 A Symposia: Advances in Materials for Oil and Gas Production Custom Cold Working of Nickel Alloy Tubulars for Size, Strength, and Corrosion Resistance
James Crum, Brian Baker, Julian Roberts - The many diverse requirements for seamless tubular products used in oil and gas down hole applications require a wide range of custom products. The level of required corrosion resistance is determined by temperature and the corrosive nature of the environment. This requirement is satisfied by proper selection of Fe-Ni-Cr-Mo or Ni-Cr-Mo alloys with sufficient alloy content to resist attack under even extreme conditions. A high level of strength is required to withstand internal pressure as well as the inherent weight of thousands of feet of tubing in the string. In solid solution alloys, cold work is the usual method of strengthening. Cold work can be applied by pilgering, drawing and roll extrusion to the desired strength level, sometimes exceeding 160 Ksi (1,100 MPa), while maintaining good ductility and meeting limiting hardness levels.

Fraser King, Miroslav Kolar, Peter Maak - The Nuclear Waste Management Organization (NWMO) is carrying out a research and development program to support implementation of Adaptive Phase Management for the long-term management of Canada’s used nuclear fuel.  The NWMO program includes technologies associated with a deep geological repository (DGR) for used fuel in a suitable geological formation, such as crystalline rock or sedimentary deposits.  Any such repository would be based on a multi-barrier design, comprising a number of natural and engineered barriers.  One of the engineered barriers would be a long-lived used-fuel container designed to provide long-term containment and isolation of used fuel for a considerable length of time.  Copper is the reference container material for the disposal of used fuel in a DGR in crystalline rock, whilst carbon steel is being considered for a repository in sedimentary host rock. The corrosion behaviour of the container will change with time as

Mon. 4:40 - 5:05pm Orange County Convention Center - S320 G Symposia: Corrosion and Scaling in Geothermal Applications The Application of Risk Based Assessment to Geothermal Energy Plant
Keith Lichti, Rosalind Julian, Monika Ko, Michael Lee - Risk Based Assessment (RBA) for inspection activities within geothermal energy plants has become commonplace in New Zealand to control the risk of premature or unexpected failure and for maintenance planning. Geothermal energy companies often administer their own pressure vessel inspection requirements following recognized standards such as AS/NZS 3788:2006, with audit and certification provided by accredited inspectors. The RBA methodology is based on the ability to predict the corrosion chemistry in key parts of the plant so that material-environment combinations can be modeled. This allows for the prediction of damage mechanisms and the most likely location in the plant for that damage to occur. The intent of the RBA process is to provide operators with a targeted approach to predict areas of potential damage, and thus the ability to focus their time and resources. The RBA provides a basis for “what and when to inspect” and a

Mon. 4:40 - 5:05pm Orange County Convention Center - S330 E Symposia: Control of Corrosion in Oil and Gas Production with Inhibitors Selection of Corr. Inhibitors Under Oil/Water/Gas Flow Conditions in Deep Offshore Catenary Risers
Cheolho Kang, KAVITHA TUMMALA, Alvaro Augusto Oliveira Magalhes - The multiphase flow characteristics can be changed with the change of pipeline topography in deep offshore oil and gas production. The increase of corrosion rate and decrease of inhibitor performance in the risers can be occurred due to the change of multiphase flow characteristics (e.g. severe slugging). For the simulation of offshore flow lines and risers, the experiments were carried out in a 44 m long, three different pipeline inclinations of 0, 3 and 45 degrees, industrial scale multiphase flow loop. In this paper, the effectiveness of the three commercial corrosion inhibitors were outlined using 25 cP oil at 80% water cut and at three different gas velocities (0.7 m/s, 3 m/s, and 6 m/s). All tests were carried out at a liquid velocity of 1.5 m/s, a system pressure of 6 bar (76 psig) using carbon dioxide gas as the gas phase, and a temperature of 50°C. Also, the effect of inclination on the flow characteristics (e

Mon. 4:40 - 5:05pm Orange County Convention Center - S230 A Symposia: Assessment and Control of Reinforcement Corrosion in Concrete Structures Early Corrosion Testing & the Importance of Interpretation to Provide Long-Term Preventive Measures
Paul Noyce, Gina Crevello - Corrosion failures account for the degradation of infrastructure causing billions of dollars in repairs annually. These failures, more importantly, cause health and safety issues which have led to the loss of human life. This has recently been brought to the attention of the broader public and congress in the Corrosion Prevention Act, March 2007 and the Bridge Life extension act March 2009. As corrosion engineers have often stressed stricter procedures on when, what and who should be assessing corrosion behaviour can curb these significant losses and monetary costs. The following paper addressed preventative maintenance and testing, proper specification of the required tests based on a multitude of factors, and the importance of accurate interpretation of this data by qualified professionals. Engineers are called in to test for corrosion behaviour once a structure has exhibited corrosion related damages. At this stage of the structure’s life, the costs o

Paul Roman, Kumar Sridharan, Todd Allen, Jacob J. Jelinek, Guoping Cao, Mark Anderson - Materials performance in supercritical carbon dioxide has been explored as part of ongoing research for the supercritical CO2 Brayton cycle. The supercritical Brayton cycle is under consideration for power conversion of nuclear process heat and other energy-related applications because it allows for a system simplification and high power conversion efficiencies. Testing was carried out in a high temperature high pressure autoclave designed and constructed for testing materials corrosion in supercritical CO2 (SC-CO2) environments at temperatures and pressures up to 650°C and 20 MPa respectively. The system is equipped with a gas chromatography mass spectroscopy (GCMS) unit for measuring inlet and outlet gas compositions to ensure consistent gas chemistry. Corrosion behavior of select alloys was studied after exposure to SC-CO2 at 450°C, 550°C, and 650°C and 20MPa for exposure duration up to 1000

Margareth Dugarte - Modeling Performance of Galvanic Point Anodes for Cathodic Prevention of Reinforcing Steel in Concrete Repairs Margareth Dugarte* and Alberto Sagues** *Universidad del Norte **University of South Florida This paper addresses projecting the performance of point anodes for patch repairs applications as function of service parameters and anode aging. Input data from a concurrent experimental test program are presented as well. Modeling of a generic patch configuration was implemented by a simplified finite differences method. The model calculates the throwing distance that could be achieved by a given number of anodes per unit perimeter of the patch, concrete thickness, concrete resistivity, amount of steel and amount of polarization needed for cathodic prevention. The model projections and aging data suggest that anode performance in likely application scenarios may derate soon even if a relatively optimistic 100 mV corrosion prevention criterion were assumed. 3D re

Tue. 8 - 8:25am Orange County Convention Center - S320 D Symposia: Corrosion in Nuclear Systems Effect of Solute Addition on Stress Corrosion Cracking Growth in Neutron-Irradiated Stainless Steels
Yugo Ashida, Peter Andresen, Gary Was - In order to understand irradiation assisted stress corrosion cracking (IASCC) mechanism and to establish strategies for IASCC mitigation, crack growth data were obtained on neutron-irradiated stainless steels with solute additions. These alloys include PS02 (316L+Hf, 9.6 dpa), IP01 (304 -C+P, 4.4 dpa), and MS01 (304+Ti, 10.7 dpa). The specimens were 8 mm round compact tension (RCT) type, which were irradiated in BOR-60 fast reactor. At the University of Michigan, crack growth rate (CGR) tests were conducted under constant K conditions in BWR NWC, BWR HWC, and PWR water at 288°C and 320°C. In addition to the CGR data, the fracture surfaces were examined using scanning electron microscopy (SEM) to identify the path of crack growth and the evidence of solute addition. Comparing to the data acquired through cooperative IASCC research (CIR) program on the solution annealed commercial alloys and the reference high purity alloy, the role of solute a

Arne Dugstad, Malgorzata Halseid - When dense phase CO2 is depressurized and forms a two phase gas/liquid system, impurities with lower solubility in the gas phase than in the liquid phase will accumulate in the liquid phase when the system is depressurized via the gas phase. Partitioning and corrosion experiments were run at 4 and 25 °C in autoclaves that were loaded with dense phase CO2 and small amounts of water, NO2, SO2 and H2S and then partly depressurized. The experiments showed that H2S, SO2, NO2 and water accumulated while O2 was depleted in the remaining liquid phase. The carbon steel specimens that were exposed in the autoclaves corroded significantly after the system was partly depressurized. Lowest corrosion (< 0.1 mm/year) rates were measured in the system with CO2 and water (500-1200 ppmv) only. The corrosion rate is reasonably low because the water phase quickly becomes saturated with corrosion products that reduce the corrosivity. The situation was different when the

Tue. 8 - 8:25am Orange County Convention Center - S220 A Symposia: Advances in Materials for Oil and Gas Production SCC Mechanism of 2205 Duplex Stainless Steel Under High H2S-CO2 Pressure with High Cl– Content
Jinhui Ding, Lei Zhang, Minxu Lu - The stress corrosion cracking(SCC) behavior of duplex stainless steel(DSS) in H2S-Cl- environment has been discussed for a long time. However, the high H2S-CO2 pressure and the high Cl- content can coordinate to cause severe pitting or SCC of DSS. There has been limited information on the mechanism of SCC of DSS under high H2S-CO2 pressure with high Cl- content. In this paper, SCC of 2205 DSS was investigated under different H2S-CO2 pressures (300kPa H2S + 200kPa CO2, 600kPa H2S + 400kPa CO2, 900kPa H2S + 600kPa CO2) with 150000ppm Cl- at 60℃. Four-point bend test method and scanning electron microscopy analysis were combined to investigate the SCC mechanism of DSS. The effect of high H2S-CO2 pressure on SCC mechanism was discussed. The results indicated that under lower H2S-CO2 pressure, cracks initiated and propagated at pitting areas which were caused by anodic dissolution mechanism. Under 900kPa H2S + 600kPa CO2, except the pitting assisted c

Tue. 8 - 8:25am Orange County Convention Center - S320 F Symposia: Advances in Materials and Corrosion Control in Fossil and Alternative Fuel Conversion and Combustion Effect of oxy-firing on corrosion rates at 650°-750°C
Bruce Pint, Jeff Thomson - Using oxygen, rather than air, in coal-fired boilers has been studied for several years as a strategy to reduce NOx and concentrate CO2 for capture. In combination with flue gas recirculation, higher levels of CO2 are expected but increased H2O and SO2 levels also may occur. In order to understand the role of substrate composition on corrosion, a combination of commercial and model alloys are being investigated both with and without the presence of synthetic coal ash. Previous work focused on 600°C with ferritic and austenitic steel coupons to simulate conditions in current boilers. Little effect was found when the synthetic ash composition was held constant and the gas changed to predominantly CO2. The current work is considering higher temperatures for advanced boiler concepts and including Ni-base alloys and weld-overlay coupons for comparison. Oxide thickness results will be presented as a function of temperature for both air- and oxy-firing condition

Feng Gui, John Beavers, Hongbo Cong, Narasi Sridhar - Carbon steel is susceptible to stress corrosion cracking (SCC) in fuel grade ethanol (FGE). The SCC can be mitigated by either adding chemical inhibitors or removing oxygen. The present work studied the performance of inhibitors under flowing condition that simulated pipe flow using crack growth rate tests. Oxygen scavenger performance was also evaluated by slow strain rate (SSR) tests and crack growth test. Large scale flow loop test was also performed to evaluate the scavenger performance. The results suggest that the inhibitors that demonstrated effective in mitigating SCC in SSR also performed well under flowing condition. The feasibility of SCC mitigation using these two methods was evaluated based on the experimental results and economic considerations. Although oxygen control was demonstrated to be effective in the laboratory tests, removing oxygen from large volume of FGE may not be a viable option to mitigate SCC. Thus,

Jeffrey Xie, Murray Butcher, Tyler Rockwell, Katy Yazdanfar, Howard Chang - Inspection revealed that tubes of a shell-and-tube heat exchanger suffered wall loss on both the inner (ID) and outer diameter (OD) surfaces to a degree of threating the operation reliability of the heat exchanger. The shell side is cooling water and the tube side is the process side. A metallurgical characterization was conducted on the heat exchanger carbon steel tubes to investigate the failure mechanism and provide potential recommendations for mitigation. Tubes and scales were characterized in term of microstructure, morphologies and compositions using SEM/EDX, TGA-FTIR and XRD techniques. The tubes were found to suffer corrosion on both ID and OD surfaces in the form of pitting corrosion. The pitting corrosion was present on the entire ID surface, but was shallower than the pitting corrosion on the OD surface. Pitting corrosion on the OD surface was predominant and would be responsible for potential le

Karly Moore, Cathleen Shargay - Duplex and super duplex stainless steels (SS) are often used in corrosive aqueous environments containing chlorides based on their excellent resistance to chloride pitting and stress corrosion cracking (SCC). However, duplex SS are not immune to these mechanisms under severe conditions and hence, the limits for successful use need to be understood. This paper correlates experiential data from case histories of duplex SS uses in refineries with research that has been done by the industry thus far on chloride SCC. These correlations are used to define application limits and to reveal gaps needing further research on this phenomenon.

Khaled Habib - A critical (steady state) value of the resistivity of different organic coatings was determined by a combination of optical shearography and electrochemical impedance spectroscopy (EIS). The behavior of organic coatings, i.e., ACE premium-gray enamel, white enamel, beige enamel (spray coatings), a yellow acrylic lacquer, and a gold nail polish on a metallic alloy, i.e., a carbon steel, was investigated over a temperature range of 20-60 0C. The value of the resistivity of coatings was determined by correlating the in-plan displacement of the coating (by shearography over a temperature range of 20-60 0C) and the value of the alternating current (A.C) impedance of the coating by EIS in 3% NaCl solution. The integrity of the coatings with respect to time was assessed by comparison the measured value of resistivity to the critical (steady state) or asymptotic value of resistivity. In other words, by shearography, measurement of coating properties could be performed indepe

Yasuhide Ishiguro, Takeshi Suzuki, Yukio Miyata, Mitsuo Kimura, Tetsu Nakahashi, Hideo Sato - Corrosion-resistant-enhanced stainless steel OCTG of 17Cr is discussed in terms of sweet and sweet-sour environments in comparison with martensitic API-13Cr, 13Cr-mod., 15Cr and duplex 22Cr or 25Cr. Especially in CO2 corrosion, the application limit temperature is 230deg.C (450deg.F) in 17Cr, which shows the highest temperature compared with 130deg.C (270deg.F) in API-13Cr, 165deg.C (330deg.F) in 13Cr-mod., 200deg.C (390deg.F) in 15Cr. Other corrosion data in 17Cr such as SSC and pitting resistance also represent better corrosion-resistant characteristics than any other martensitic stainless OCTGs of 13Cr, 13Cr-mod. and 15Cr. In addition, metallographically, OCTG of 17Cr is composed mainly of martensite and ferrite with retained austenite. Therefore, 17Cr as well as martensitic stainless steel OCTGs has high-strength at room temperature without any cold-working-based strengthening seen in d

Tue. 8:25 - 8:50am Orange County Convention Center - S320 D Symposia: Corrosion in Nuclear Systems Cracking Issues Associated with the Use of Seal Cap Enclosures on Reactor Coolant System Valves
David Alley - Due to the presence of actual leakage, or the potential for leakage, through the body to bonnet bolted connection of some reactor coolant system check valves, some pressurized water nuclear power plants in the United States have installed Seal Cap Enclosures to contain pressure boundary leakage. These enclosures are not designed to function as the pressure boundary. That function is retained by the body to bonnet to bonnet bolts. The design of the seal cap enclosures precludes the inspection of the pressure boundary bolts which are constructed from A286 stainless steel. This paper considers operating experience associated with these enclosures, the environment within the enclosures, the potential for cracking of the enclosures, the potential for cracking of the bolting material within the enclosures, and actions taken to date by the NRC and nuclear industry with respect to these enclosures.

Because dissolved oxygen concentration is known to be the most significant variable contributing to susceptibility of ethanol pipeline steels to ethanol stress corrosion cracking (eSCC), knowledge and control of dissolved oxygen levels in FGE is valuable for predicting and controlling eSCC.

Jennifer Collier, Sankara Papavinasam, Jian Li, Chao Shi, Pei Liu - The ability to use existing steel infrastructure for carbon capture, transportation and storage and (CCTS) networks is critical to their realization. As such, there is a need to understand the corrosion performance of these materials under CCTS operating conditions. While the corrosion of steels in pure, dry carbon dioxide is negligible, the carbon dioxide stream in CCTS may contain significant levels of impurities. Therefore the effect of potential impurities on the corrosion of steels exposed to the carbon dioxide stream must be investigated. In the current work the effects of impurities such as water, oxygen, sulphur dioxide (SO2) and nitrogen oxides (NOx) on the corrosion of carbon and stainless steels under supercritical carbon dioxide conditions were investigated using a high pressure rotating cage. The corrosion of the steels was analyzed by mass loss and the morphology and composition of the corrosion produc

Sophia Ekman, Jesper Flyg, Gary Carinci, Arne Bergquist, Rachel Pettersson - Condensing flue gases are highly corrosive and present severe challenges in terms of materials selection. The sulphuric acid condensation which occurs in coal-fired power plants has been long recognised as causing corrosion in FGD units, but the more complex conditions which can arise with increasing combustion or co-combustion of biomass and waste have been less thoroughly investigated. In this paper results are presented from laboratory tests designed to simulate the corrosive conditions in flue gas cleaning systems and based on analysis of actual condensate The major focus is on waste combustion, where the major condensate component is hydrochloric acid but varying amounts of H2SO4, HBr, HNO3, HF and metal ions may additionally be present.

Mauricio Olivares, Ben Brambila - Risk Based Inspection (RBI) of Above-Ground Storage Tanks is a technology for determining the optimal run length of a tank before a costly and time-consuming internal inspection is required. There are various methods for calculating appropriate inspection intervals which rely on risk models. The risk calculations are generally based on the tank’s design, operation, and corrosion/inspection history. However, there is little published material giving guidance on actual, quantitative models that can be used effectively to calculate risk. Probability and consequences of failure for tanks require a very different and widely varying set of calculations than pressure vessels and piping, and there are a number of decisions that must be made in the calculation which may have a significant impact on the results. The purpose of this paper is to overview some of the nuances associated with the calculations used to perform tank RBI. It also explains the effect o

Amer Jarragh, Sandip Kuthe, Abdulwahab Al-mithin, Sharad Londhe - Kuwait Oil Company is major player of global standing in the field of exploration, production and transportation of crude oil and gas. Effluent water, an essential byproduct of crude from the Gathering Centers where oil separation and processing takes place, was previously disposed of in evaporation pits. Effluent water disposal plants were later constructed and commissioned in east and south Kuwait fields, for treating the effluent water collected from several gathering centers and then re-injecting into the reservoir by disposal wells, to maintain the reservoir pressure. Effluent water is known for its high corrosivity due to high content of chloride. Various types of chemicals are used to control corrosion, scales and microbial growth in these waters. Though during the design stage some chemicals have been selected based on lab tests, proper field trials were not conducted in the early stages after commissioning.

Additions of other components, for ease of processing, lower cost, and other additional functionality, make their impedance even lower. The lower impedance, in connection with high water permeability and ion conductivity, indicates the proneness of a coating to blister and delaminate from a substrate. As an effort to reduce the number of and finally eliminate these defects from a commercial poly vinylidene chloride (PVDC) primer, a systematic EIS study had been conducted on films formed with incremental components from just the binder resin to a full commercial formulation. Binder resins were found determining the inherent/initial impedance of a coating. However, due to the strong interactions between binders, fillers, solvents, and additives, the final impedance of a coating after immersion in electrolyte was f

Daniel Sandana - Transporting anthropogenic CO2 in pipelines is an essential component in the realisation and implementation of Carbon Capture and Storage (CCS). Transportation of dense CO2 has generally been the preferred economic solution, but projects in the United Kingdom (UK) have also considered transportation of gaseous CO2. Whichever option is selected, provision may need to be made to mitigate or prevent internal corrosion risks. This will require identifying and defining in the CO2 specification the maximum levels of water and impurities, e.g. nitrogen oxides (NOx) and sulphur oxides (SOx), such that internal corrosion risks are maintained at an acceptable level throughout the proposed service life of a pipeline. Equally, should there be a process upset in the CO2 stream conditioning procedure (e.g. failure of dehydration unit), then potential internal corrosion risks will need to be clearly defined in order to establish an effective mitigation strategy that maintains p

Xihua He - Zirconium-based cladding material exposed to coolant water during nuclear reactor operations could absorb hydrogen up to 800 ppm. During extended dry storage, as the cladding cools with time, the hydrogen inside the cladding couldprecipitate as hydrides; furthermore, both existing and newly formed hydrides may reorient. Depending on size, distribution, and orientation, these hydrides may lead to premature fracture, as a result of hydride embrittlement or delayed hydride cracking. Because the U.S. is actively considering extended dry storage as an alternative approach to manage spent nuclear fuel and the amount of high burnup fuel with possibly high hydrogen concentration is increasing as a result of changes in plant operating conditions, there is a need for data on hydride reorientation and its influence on mechanical behavior during extended storage. This work reports (i) methods to form hydrides ofvarious concentration levels in cladding, (ii) conditions when hydrides r

Sytze Huizinga, Marc Wilms, Jan deJong, Ralph Haswell - In the past, failures have occurred of 13Cr weldable martensitic stainless steels (lean grades) in sweet service as a result of Intergranular Stress Corrosion Cracking in the Heat Affected Zone. Initial lack of understanding of the detailed mechanism has hampered application of the material, including the more resistant but not immune higher alloyed grades. A cracking mechanism for the latter grades was proposed recently based on laboratory studies. The present study aims at confirming this mechanism and unambiguously proving the effectiveness of Post Weld Heat Treatment for actual, representative field welds. By performing four point bend stress corrosion cracking tests on welded specimens from several sources, both with and without PWHT, in representative service conditions and linking the results with detailed Transmission Electron Microscope (element analysis) studies, clear evidence was found for the proposed mechanism.

Vinay Deodeshmukh, Mike Newburn, Lee Pike - Recent work by our group has shown that a relatively short-term (200h) hot corrosion exposure using two-zone furnace rig is quite useful in ranking performance of the high-temperature alloys. However, certain alloys can be susceptible to catastrophic hot corrosion after long-term exposure; moreover, long-term hot corrosion exposure may assist in discerning performance of the alloys that exhibit good hot corrosion resistance after short-term exposure. This paper is focused on the Type I hot corrosion resistance of high-temperature alloys exposed for 1050h at 900oC. The Ni-base alloys selected for this study are N06230, N06017, N07214, N06002, N12160, while Co-base alloys are R30188, R30155, and Co-Ni-Fe-Nb-Ti-rich alloy. Alloy performances were ranked by assessing weight-change behavior and metal recession measurements which includes metal loss, average internal penetration, and maximum internal penetration.

In Jun Park, Jin-Ho Kim, Taeheum Nam, Jung Kim - The application of bio-ethanol to automotive fuel is incomplete due to concerns regarding the corrosion problems that might occur in light metal components for fuel and engine system, particularly aluminum alloys. There are only a few studies on the corrosion characteristics of the automotive component materials under the bio-ethanol blended fuel conditions, especially under high temperature that might be reached in engine driving. Our previous studies verified that a thermally activated chemical reaction between aluminum and ethanol, which results in the formation of aluminum alkoxide, was found to be the key process of the aluminum corrosion in the high temperature ethanol blended fuel. However, it has not been established the appropriate electrochemical methods to evaluate corrosion characteristics of aluminum alloys, due to very low conductivity of electrolyte, high temperature and difficulty of 3-electrode cell system configurat

Amer Jarragh, Abdulwahab Al-mithin, Surya Prakash, Moavin Islam - Control and mitigation of internal corrosion in the oil and gas production sector is of paramount importance for ensuring asset integrity and projected service life of components. Conventional techniques for internal corrosion control include chemical treatments such as the use of corrosion inhibitors, environmental modification such as deaeration and pH control, protective coatings and linings, cathodic/anodic protection, using better quality materials, and design. An unconventional, non-intrusive internal corrosion mitigation technique has become available during the last 10 years which claims to solve typical problems in all types of water handling systems such as rust and corrosion, scaling and fouling, as well as microbiological problems. This technology is reported to have been developed empirically, and uses specifically modulated molecular oscillations or lattice oscillations of the fluid for its beneficial eff

Peter Ellis, Kwei Meng Yap, Sridhar Srinivasan, Richard Horvath - Sulfuric acid alkylation (SAA), the conversion of olefins and butane to high-octane alkylate using highly concentrated sulfuric acid as a catalyst, is a very profitable refinery operation. While there are powerful economic incentives to maximize SAA unit throughput, until recently there were only minimal data available for quantitative assessment of sulfuric acid corrosion rate under refining alkylation plant conditions. Thus, a joint industry program (JIP) entitled “Prediction of Corrosion in Sulfuric Acid Alkylation Units” was launched in January 2006 and completed in January 2010, to develop an empirical predictive, data-based computer model (Predict®SA) for quantification/prediction of corrosion rates of carbon steels and selected stainless steels and nickel-base alloys under SAA conditions. This model is based on the results of an extensive experimental corrosion program that generated hundreds of corrosion rate

Vincent Roche, Cécile Millet, Fernando Bonilla, Dorian Allue, Florian Schultes - UV-curable varnishes are used to protect pipes against corrosion during transport and storage prior to their final use (i.e. temporary protection). A positive aspect of these varnishes is that they are environmentally-friendly because volatile organic compounds (VOC’s) are not released during their application. In-house qualification of varnishes for temporary protection currently involves 3-6 months outdoor exposure tests at selected geographical sites, in particular at a seaside site classified C4 according to ISO 12944-2 (Dunkirk). However, requirement of a good pipe appearance for increasingly longer periods of time has lead to a continuous demand and offer of new UV-curable varnishes, and a corresponding need for longer-lasting outdoor exposure tests. It would be convenient to be able to assess new varnishes by means of short-term laboratory tests. Accordingly, neutral salt spray tests such as thos

Tue. 9 - 11am Orange County Convention Center - S230 C Basic Workshop: Proper Use of Coatings Inspection Instruments and Standards
Proper use of coatings inspection instruments, as well as knowledge of industry standards is vital for all parties involved in corrosion protection using protective coating and lining systems. Lack of knowledge of industry requirements and/or improper use of coatings inspection equipment can result in catastrophic premature coating failure and, if undetected, can cause product contamination and/or section loss of structural steel. Painting contractors, who are ultimately responsible for quality control on painting projects, must have knowledge of instrument use to prove compliance with the governing project specification. Facility owners who perform quality assurance during painting operations must have knowledge to help ensure the protection they are paying for is being performed according to the requirements of their specification. Finally, coating manufacturers need to ensure their materials are being applied properly, to well-prepared surfaces. Without knowledge of inspection equipment use and an understanding of industry standards, the contractor, facility owner and the coating manufacturer have little way of determining whether the coating system will perform. This workshop on the use of surface preparation and coating application inspection instrumentation and industry standards is comprised of an orientation to the basics of instrument and standards use, followed by a series of hands-on workshops. Small groups will work with gages and standards for: • Measuring Ambient Conditions • Measuring Surface Profile • Assessing Surface Cleanliness (SSPC Visual Guides) • Detecting Pinholes and Voids In Coatings • Detecting Surface Chlorides • Measuring Coating Thickness Co-chairs: Matthew Fajt and Rich Burgess, KTA-Tator, Inc.

Tribhuwan Kathayat, Rick Hill, Rajesh Goyal, Raghu Shant - Authors: T S Kathayat, R. T. Hill, Rajesh K. Goyal & J. Raghu Shant Abstract: The presence of severe corrosive environment along with higher external pressure in Black Sea has led to develop high strength heavy wall line pipe. The paper will cover the successful development of high strength SAWL485 SFDU (33”ODX39.5 mm WT) line pipe manufactured by the JCOE technology. Step wise preventive measures were taken during pipe manufacturing & submerged arc welding processes to control the weld & HAZ hardness, which is essential to improve the HIC & SSCC performance of line pipe in severe sour environment. Circumferential residual stress was controlled in order increase the HIC resistance. The welding parameters were closely monitored to obtain higher impact toughness at low temperature in weld and HAZ. The proper selection of wire & flux has resulted average CVN impact > 100 J at -30 °C in weld centerline. The study of weld micros
