Challenges include the evaluation and selection of the most suitable chemical treatment and monitoring methodologies to be implemented for reducing damage posed by increased corrosive stagnant conditions which were more severe than experienced during normal operations. When possible the anticipated duration of the shutdown period needs to be taken into careful consideration along with downhole completion and artificial lift pumping systems before implementing the preferred treatment and monitoring programs.

Mon. 9 - 9:25am Ernest N. Morial Convention Center-New Orleans - Symposia: Achieving Intended Service Life; Corrosion Control Strategies for Reinforced Concrete Structures Comparison of Corrosion Management Strategies of RC Structures Using a Reliability-Based Approach
Qindan Huang, Siavash Sajedi, Mohammad Mohebbi - Chloride induced corrosion is one of the main causes of premature damage in steel reinforced concrete (RC) structures such as highway bridges exposed to deicing salts. Corrosion can affect the service life performance of the RC structure by reducing the diameter and yielding strength of rebar, and weakening the bond at the steel-concrete interface. These effects could change stiffness, load carrying capacity, and even failure mode of the structure, which increases the risks of sudden failure without warning. It is reported that the costs associated with monitoring, maintenance, repair, and rehabilitation of corroded RC bridges in the US are overwhelming. To ensure the serviceability and safety of the RC structure, and reduce the corrosion related costs, optimum corrosion management strategies should be utilized. Different procedures can be used to manage the corrosion related problems in RC structures (e.g., using various repair
Symposia
Mon. 9 - 9:25am Ernest N. Morial Convention Center-New Orleans - Symposia: Corrosion of Biomedical Materials and Devices In-vitro to In-vivo Correlation of Corrosion in Nitinol Cardiovascular Stents
Srinidhi Nagaraja, Stacey Sullivan - There is public health need to understand the effects of corrosion in nickel-containing implantable medical devices. Corrosion of these devices may result in adverse events such as loss of the implant’s mechanical integrity and nickel toxicity/sensitization. This is particularly important for Nitinol devices since its corrosion resistance is highly dependent on manufacturing process. The objective of this study was to assess whether current bench testing for corrosion accurately captures observed in-vivo corrosion and nickel leaching of Nitinol cardiovascular stents. Generic Nitinol stents were manufactured using one of four different surface treatments that produced stents with distinct thermal or native oxides. In-vitro assessments such as Auger surface characterization, nickel leach testing, and potentiodynamic polarization (ASTM F2129) were performed. In addition, these stent groups were implanted into minipigs in either a single stent o

Samuel Zelinka, Joseph Jakes, Grant Kirker, Stefan Vogt, Vine David - Copper based waterborne wood preservatives are frequently used to extend the service life of wood products used in outdoor environments.  While these copper based treatments protect the wood from fungal decay and insect attack, they increase the corrosion of metals embedded or in contact with the treated wood.  Over the past ten years, several studies have looked at the corrosion mechanisms for metals in contact with copper treated wood.  These studies have concluded that the most plausible corrosion mechanism involves the migration of copper ions from the wood treatment through the wood to the metal surface, where they are then reduced.   Despite this, under almost all conditions, copper has not been detected in the corrosion products as the proposed mechanism would imply.  Recently, synchrotron based X-ray fluorescence microscopy (XFM) was used to examine the wood that had been in direct contact with metal

Mon. 9 - 9:25am Ernest N. Morial Convention Center-New Orleans - Symposia: Cost of Cleaning or Not; Review of Methods and Fundamentals of Chemical and Mechanical Cleaning A Novel Non-Toxic Method for the Decontamination of Silicate Scales - A Case Study
Samar Gharaibeh, Roxanne Shank, Tom McCartney - Silicate scale formation is a technical challenge for industrial process water operators and a financial burden for all industries that use water to support their operations. Silicates are mainly present in power-generating units such as boilers and condensers, heat exchangers in refineries and petrochemical plants, water desalination, and other industrial equipment such as degreasers in paper mills. Wherever this scale is present, its removal is crucial due to the fact that it decreases thermal conductivity and fluid flow rate. The chemical nature of the silicate scale depends on the chemistry of the water, and the acceptable “industry standard” for dissolving silicates deposits is hydrofluoric acid, often delivered by adding ammonium bifluoride, NH4·HF2 to a stronger acid solution. Although, this approach is effective, it also requires meticulous attention to issues such as hazard potential (generation of HF in-situ) and acid-dr

Mon. 9 - 9:25am Ernest N. Morial Convention Center-New Orleans - Symposia: Geothermal Scaling and Corrosion Corrosion resistance of the super-austenitic stainless steel UNS S31266 for geothermal applications
Ralph Baessler, Sandra Lemanchet, Joana Sobetzki - Super-austenitic stainless steels cover grades with high chromium (20 to 27%), high nickel (18 to 31%) and high molybdenum (4 to 6%) contents. Within this family, the 6%Mo high nitrogen grade UNS S31266 was developed to combine the beneficial influence of chromium, tungsten, molybdenum and nitrogen on its mechanical and corrosion properties. Due to 22% nickel, 24% chromium and 0.4% nitrogen additions, this alloy exhibits a very stable microstructure, less prone to intermetallic phase precipitation than the other highly alloyed super-austenitic stainless steels.   This paper will deal with the corrosion resistance of UNS S31266 in artificial geothermal water with high salinity and low pH. Long-term static exposures and electrochemical tests were conducted at various temperatures to evaluate the pitting, crevice and stress corrosion cracking resistance of this material. The results show that this grade is resistant up to 220°C.

Mon. 9 - 9:25am Ernest N. Morial Convention Center-New Orleans - Symposia: Offshore Coating Technology Symposium New developments in coatings for extended lifetime for offshore wind structures
Claus Weinell, Troels Mathiesen, Peter Nielsen, Anders Black - After more than 15 years’ service life of the first large offshore wind farms in the North Sea, mostly positive experiences are reported regarding the condition of the protective coating systems. Today however, the requirements for corrosion protection for new projects are often extended to at least 25 years’ maintenance-free lifetime. In comparison, the highest durability class described in ISO 12944 is more than 15 years until first expected maintenance. Therefore, much needed committee work is in progress with the intent to update ISO 12944 with extended durability classes. In order to bring down the construction cost of the support structures for offshore wind, initiatives have been taken to industrialize the coating application process and to use standard components wherever possible. Extended pre-qualification tests are needed in order to convince owners and certifiers that new coating systems may actually hav

Mon. 9 - 9:25am Ernest N. Morial Convention Center-New Orleans - Symposia: Anodic & Cathodic Protection Influence of Anodic Current on Corrosion Protection Conditions of Buried Steel Pipeline Under Cathod
Tomoyuki Nagai, Yamanaka Hidefumi, Akinobu Nishikawa - Cathodic protection is being applied to buried steel pipelines and polarized potential of pipelines is kept less noble than the protection potential criterion, -0.85 V vs. Cu/CuSO4. However, instantaneous anodic current has been infrequently observed in some fields even though polarized potential of pipelines is kept less noble than the protection potential criterion. In this study, the influence of instantaneous anodic current on corrosion protection of buried steel pipelines under cathodic protection was evaluated and the oxidation reaction causing anodic current was investigated to some extent. As a result, it was found that most of the anodic current was not attributed to corrosion reaction and the maximum value of corrosion rate of steel was as little as 1.8 μm/year. Therefore, it was considered that there was no matter on buried steel pipelines even though the instantaneous anodic current occurred under the protection

Mon. 9 - 9:25am Ernest N. Morial Convention Center-New Orleans - Symposia: Pipeline Integrity Aim Corrosion Management: Perfect Key Performance Indicators
Sankara Papavinasam - Asset integrity management (AIM) ensures that the assets perform effectively and efficiently for the entire duration of their designed life.  Implementation of AIM process requires evaluation of all risks.  One of the risks to oil and gas infrastructures including pipelines is corrosion.  Therefore, controlling corrosion risk is a key component of AIM.  The 5-M methodology is available to develop and implement strategies to control corrosion. The 5-M methodology consists of five individual elements: modeling, mitigation, monitoring, maintenance and management. The 5-M methodology implementation requires establishment of several key performance indicators (KPIs). These KPIs track corrosion control implementation of an asset for its entire life, i.e., during design, construction, commission, operation, and abandonment stages.  This paper illustrates fifty (50) KPIs that were developed based on industry surveys and failure analysis; application of these 50

Mon. 9 - 9:25am Ernest N. Morial Convention Center-New Orleans - Symposia: Refining Industry Corrosion Evaluate Ammonium Chloride Corrosion Potential with Water Partial Pressure
Huang Lin, Vishal Lagad - Ammonium chloride (NH4Cl) salt, because of its hygroscopic characteristic, can be very corrosive and often leads to heavy pitting and localized corrosion. Even in the absence of free liquid water, at a certain high relative humidity, ammonium chloride salts start absorbing water from the vapor phase and forming a concentrated NH4Cl aqueous phase. This concentrated liquid NH4Cl solution has a low pH and can be very corrosive, causing pitting even in stainless steels and some nickel alloys.  Hydroprocessing and catalytic reforming reactor effluent streams, FCCU and coker fractionator overheads and crude tower overheads are typically subject to severe NH4Cl corrosion, especially when the crude slates have high chloride contents. The potential of NH4Cl salt deposition has been related to NH3 and HCl partial pressure. With high amounts of NH3 and chlorides in the vapor phase, a large amount of NH4Cl salt can form and might foul equipment. However, this does

Steve Sparkowich, John Banker, Paul Manning - Nickel-base HYBRID BC1 Alloy offers superior corrosion performance to established Ni-Mo and Ni-Cr-Mo alloys in several specific severe corrosive environments.  Explosion cladding of BC1 to a lower cost base metal provides significant cost reduction for pressure vessels and other process equipment requiring heavier thicknesses (typically 12mm (0.5 in) and greater).  Alloy BC1 explosion clad plate with SA-516-70 base metal was extensively evaluated for compliance with clad metal specifications, corrosion resistance, thermal stability and ability to be formed, fabricated and heat treated for ASME Code pressure vessels.   The corrosion resistance properties of the BC1 cladding layer were unchanged from typical solution annealed properties after the sequence of explosion cladding, head forming, and post weld heat treating.  Bond shear strength and product ductility of the clad plate were compliant with the requirements of SA-265.  Ultras

Mon. 9 - 9:25am Ernest N. Morial Convention Center-New Orleans - Symposia: Coatings and Inhibitors Assessment of Corrosion De-Adhesion of Marine Paints on Steel Using Scanning Kelvin Probe
Nathalie Lebozec, Andrej Nazarov, Dominique Thierry - Marine paints are complex polymeric systems containing various layers of coatings. They are heavily pigmented that leads to perfect barrier properties relatively to diffusion of water oxygen and corrosion activating ions. When paint systems including Zn rich primer are used, a sacrificial protection of the steel substrate is provided by zinc. In total, the thickness of paints is more than 300-350 mm that significantly delays the degradation and visual observation of corrosion failures. In this study, three industrial marine paints were studied. One systems was a one-layer barrier epoxy mastic while the others were full marine paint systems consisting of multi-layers of epoxy paint on one side and a system with Zn rich primer on the other side. A scanning Kelvin probe (SKP) instrument was used to study the mechanism of paint failure. This technique is sensitive to metal-polymer interface and gives a rather quick response on th

Mon. 9 - 9:25am Ernest N. Morial Convention Center-New Orleans - Symposia: Environmental Assisted Cracking - Research in Progress Environmentally Assisted Stress Corrosion Cracking of 5xxx Al Alloys in Atmospheric Environments
James Burns, Patrick Steiner - Intergranular stress corrosion cracking (IG-SCC) testing has typically been performed with specimens fully immersed in electrolytic solution due to experimental convenience. However, true atmospheric environments are often typified by salt-spray, rain, or a deliquesced thin-film electrolyte. These environments differ in the pertinent mass-transport distances and/or local ionic resistance influencing the cathodic/anodic reaction kinetics that control the crack tip hydrogen production. In this study the effect of atmospheric environments on the IG-SCC behavior of AA5083-H131 and AA5456-H116 tensile samples is studied using slow-rising displacement testing and high-fidelity monitoring of crack growth kinetics. These results are analyzed in the context of a coupled anodic dissolution and hydrogen-embrittlement mechanism, in which the observed reduction in the IG-SCC susceptibility of the atmospheric environments is cathodically limited. This would indic

Mon. 9:25 - 9:50am Ernest N. Morial Convention Center-New Orleans - Symposia: Environmental Assisted Cracking - Research in Progress Mitigation of Intergranular Stress Corrosion Cracking in Al-Mg by Electrochemical Potential Control
Matthew McMahon, John Scully, James Burns - The AA5xxx-series is a lightweight family of aluminum alloys utilized in marine vehicles in place of heavier steel components for increased speed and fuel efficiency [1]. Specifically, AA5456 is solid solution strengthened by a supersaturation of the Al-matrix with 5 wt. % Mg. However, mildly elevated temperatures can lead to precipitation of the β phase (Al3Mg2) on the grain boundaries. This process is termed sensitization and is often quantified by the ASTM G-67 Nitric Acid Mass Loss Test (NAMLT)).  The β phase is highly anodic to the matrix and in the presence of aggressive environments can lead to severe intergranular stress corrosion cracking  (IG-SCC) [2]. This behavior is governed by a coupled anodic dissolution process (of the β phase and under certain conditions the Al matrix), which by the hydrolytic acidification mechanism catalyzes an aggressive local crack tip chemistry. This acidic environment lowers the crack pH, which

Mon. 9:25 - 9:50am Ernest N. Morial Convention Center-New Orleans - Symposia: Offshore Coating Technology Symposium Repair coatings for TSA
Ole Knudsen - Thermally sprayed aluminium (TSA) has successfully been used for corrosion protection for several decades. Coating lifetimes of 30 years in corrosive marine atmosphere has been documented. However, it has also been found that coating TSA with thick, protective organic coatings will result in rapid corrosion of the TSA and very short lifetimes. The TSA under a protective coating corrodes in a crevice corrosion like mechanism. Corrosion of the TSA under the paint film results in formation of aluminium chloride, which hydrolyze and acidify the electrolyte. The acidification destabilizes the protective aluminium oxide and corrosion of the TSA accelerates. The problem is avoided by not covering TSA with thick organic coatings. However, in some situations it is difficult to avoid coating the TSA. E.g. when repairing damages in the TSA in the field, the repair coating often overlaps with the TSA around. Hence, a repair coating that can protect steel, but not trigger the c

Charles Marks, Marc Kreider, Michael Little, Robert Varrin - As with many heat exchangers, nuclear steam generators are subject to the accumulation of corrosion deposits on heated tube surfaces and other internal components on the secondary (shell) side.  These deposits can have adverse effects on thermal efficiency, material integrity, and in some cases plant operability.  Accordingly, plant operators routinely devote substantial resources to limiting the rate of deposit accumulation and periodically removing the deposits through various mechanical and chemical approaches.  Since the 1980s, chemical cleaning processes with solvents designed to remove all (or nearly all) of the iron- and copper-based deposit material from the SG secondary side have been employed in dozens of different units worldwide.  Although these full-bundle “hard” chemical cleaning processes have generally been quite successful in removing large fractions of the deposit mass (typically >95%), they are comple

Bedi Aydin Baykal - Over the 20th and early 21st century, pulp and paper machinery has transformed little in terms of configuration, but materials used to construct said machines has changed from carbon steel to austenitic stainless steel and then to duplex stainless steel (DSS). Even with the new material, the reliance of the industry on insufficient data on erosion-corrosion or flow induced accelerated corrosionhas led to the selection of inadequate materials and thus frequent failures in pulp mills, evaporator and concentrator tubes etc. This warrants a study of the materials in simulated environments that they will encounter in this application. In this study, the materials that are typically used in pulp mills, including 2205 DSS and 316L Austenitic SS, were subjected to simulated black liquor and flow conditions. The response in terms of both corrosion rate and repassivation kinetics were observed using a three electrode electrochemical experiment with a rotating cylinder

This study was motivated by the need for longer-lasting implant alloys because of the increasing life expectancy of patients and the need to avoid revision surgery. The purpose of this project is to quantitatively compare the corrosion behavior of candidate titanium alloys, i.e., commercially pure titanium with and without boron (CPTi and CPTi+B) as well as Ti64 with and without boron.  Previous studies in this group have shown that small additions of boron to CPTi and Ti64 reduce the rate of corrosion compared to the parent alloys in different physiological media. This study expands the earlier work to additional test solutions, hardness measurements and microstructural evaluations.

Jeffery Clark, Joshua Addis, Boyd Laurent, James Williams - An operator in North America discovered an internal corrosion failure in a wet gas system directly below the point of injection of a water soluble corrosion inhibitor (CI). Upon further investigation an inconsistency was found between the standard laboratory based carbon steel immersion corrosion rate of the neat water-soluble corrosion inhibitor and the observed corrosion rate based on the field time to failure. For this reason studies were conducted to uncover the discrepancy between the laboratory compatibility test and the observed field corrosion rate in a wet gas system. Tests using low shear rotating cage autoclaves were performed as a corrosion screening method of the neat CI. Additionally it was desired to ensure that the product would travel with the gas and provide corrosion inhibition throughout the entire system. For this reason an additional study was conducted using a dual autoclave system to study the abil

Karl Kuklenz - This paper reviews the thermal and hydrolytic stability behavior of carboxylic acid solutions commonly used in refinery feed preparation units, and if possible, will characterize their associated daughter molecules.  Crude oils are often treated with carboxylic acids to help accomplish some of the goals of feed preparation such as pH adjustment, amine removal, and metals removal.  These acids, like the crude oil itself, are subjected to the extreme temperatures of the crude furnace when they pass through the desalter dissolved in the crude oil, or as unresolved water carryover.  Often, the thermal decomposition values for a pure acid are used to indicate the level of risk to the crude unit.  The hidden assumption is that the behavior observed with an aqueous solution is the same as it would be for the neat acid.  This paper documents the solution and headspace chemistry of aqueous solutions of carboxylic acids that have been thermally stressed in a laboratory set

Rebecca Bay, Jenifer Locke - AA5xxx series Al-Mg alloys with greater than ~3.5% Mg experience an acceleration in fatigue crack growth rate as the level of sensitization increases and fatigue loading frequency decreases when loaded in 3.5 wt% NaCl.  AA5xxx series alloys, commonly used in naval applications, are known to exhibit decreased resistance to intergranular corrosion and intergranular stress corrosion cracking due to the formation of the active Al3Mg2-β phase on grain boundaries.  β phase is metallurgically undesirable and forms on grain boundaries when slightly elevated in-service temperatures are experienced for prolonged periods of time, a phenomenon known as sensitization.  Previous studies on AA5083-H131 corrosion fatigue show that fatigue crack growth rate is accelerated by an order of magnitude for Degrees of Sensitization greater than or equal to 30 mg/cm2 at a fatigue loading frequency of 10 Hz, however, practical in-service naval ship fatigue loading occurs at

Fang Cao, Yao Xiong, Shuji Luo, Shiun Ling, Mennito Anthony - Nitrogen containing surfactants (e.g. amines, amides, imidazolines, and quaternary ammonium salts) have been commonly used active corrosion inhibitors (CI) in commercial CI packages for many years to control corrosion of carbon steel pipelines in oil and gas industry. However, in the literature, not many systematic studies have been done to compare the partitioning behavior and corrosion performance of nitrogen based CIs with different functional groups, and their inhibition mechanisms are currently not fully understood. In this study, amine-based model CI compounds with different functional groups and sulfur containing synergist molecules were selected for mechanistic study. The oil-water partitioning behavior and corrosion performance of these model compounds were investigated and correlated to their chemical structures in a variety of sweet corrosion environments.

Sylvia Kessler, Alberto Sagues, Kingsley Lau - Corrosion of epoxy coated rebar (ECR) in chloride exposed concrete can be enabled by the oxygen reduction cathodic reaction taking place on steel exposed by coating breaks. The total cathodic current would be expected to increase if the reaction locus were to extend into crevices formed at disbonded coating regions around coating breaks. To examine the possible amount of this effect, distress in the form of controlled surface breaks was created on production samples of ECR, some of which were further subject to cathodic disbondment to create surrounding disbonded regions around the breaks. The samples were cast in concrete specimens kept at ~80% RH in air and fitted with electrodes to perform cyclic polarization (CYP) in the cathodic direction and electrochemical impedance spectroscopy (EIS) measurements under open circuit conditions. Measurements performed initially and after 6 years of aging showed for the disbonded specimens a

Ben-Hamu Guy - The increase in population of the world and aging has resulted in a significant growth of orthopaedic implant surgeries. Hip and knee replacement surgeries are one of the most common surgeries in the older population. Most of the joint replacements, implants, and bone plates are generic, mass-produced components, which may not always be compatible with the patients having a specific or unusual anatomy.  In these situations, custom designed implant components are required. Additive manufacturing finds its potential utilization for the manufacturing of human bone implants. However, the deep understanding of mechanical, corrosion and fatigue properties of additive manufactured implants are still lacking. The main objective of present research is to investigate the optimum part properties for two different additive manufacturing processes, selective laser melting (SLM) and electron beam melting (EBM), for their application to medical implants.

Liang He, Yushu Wang, Preet Singh - The presence of thiosulfate ions in the paper machine white water environment has been shown to increase the pitting susceptibility of stainless steels. Understanding how different grades of stainless steels behave in thiosulfate containing environments not only helps with material selection, but also contributes to the understanding of mechanisms by which thiosulfate ions affect pitting in different alloys. As new grades of lean duplex stainless steels become available as candidate materials for the pulp and paper environments, it is important to evaluate their behavior in the thiosulfate and chloride containing environments. This paper focuses on lean duplex stainless steel grades UNS S32304, UNS S32003, and LDX 2404. Electrochemical methods were used to study the stable and metastable pitting susceptibility of selected alloys in simulated white water environments.

Roxanne Shank, Tom McCartney - Vacuum Distillation is a key aspect of the petroleum refining process, with over 80% of US refineries and nearly all Canadian refineries and upgraders capitalizing on the operational benefits of this unit. A secondary processing unit, the vacuum distillation unit (VDU) receives the heavy bottoms from the atmospheric distillation unit (ADU) and further separates them with the benefit of vacuum pressure to prevent the cracking, or break down, of the oil. The VDU is composed of an outer shell, distillation columns and a fired heat exchanger. When fouled with heavy residuum, the efficiency of the heat exchange process declines, reducing throughput and flow rate, and can introduce hot spots in the system leading to coking of the oil in the VDU. Maintenance of these units is imperative to the refining process; however, potential contamination by the heavy residuum poses significant environmental and health issues when the exchanger unit is pulled from the

Mon. 9:50 - 10:15am Ernest N. Morial Convention Center-New Orleans - Symposia: Geothermal Scaling and Corrosion Geothermal Corrosion: High-temperature pitting of stainless steels and Ni-alloys
Walter Bogaerts, I. Winston - It is well recognized that geothermal environments are highly corrosive to metals and alloys. The high corrosiveness of the environment typically arises from the combination of elevated temperatures (e.g. up to 150, 200 … 300°C) with the presence of a high concentration of chloride ions, and sometimes sulfur species. Chloride-induced pitting corrosion is an imminent materials failure mechanism under these conditions. Accordingly, a major factor in the economic exploitation of geothermal resources will be the cost-effective selection of materials that have sufficient resistance to pitting, and related corrosion phenomena such as stress corrosion cracking, to maintain component integrity. In this paper we describe the temperature dependence of the pitting corrosion resistance of a number of traditional Fe-Cr-Ni and Fe-Cr-Ni-Mo materials (e.g. Type 304 & Type 316 stainless steels, Alloy 800, 825, 600, 625) in a series of high-temperature high-pressure

The two pipelines were projected to require approximately USD 50 million in repair costs over the next 10 years. In response, a software tool was developed to calculate defect-specific corrosion rates by comparing in-line inspection data from multiple pipeline inspections. Individual defect growth rates were calculated from the matched external metal loss defects. The individual defect growth rates were then applied as projected future corrosion rates for each individual defect. Around 90% of the metal loss indications were successfully matched having axial displacement of approximately 0.1 m or less. Corrosion rate and remaining life distributions for the pipelines were generated to facilitate detailed pipeline assessment. An optimal pipeline de-rating and repair strategy was develo

Yuzo Daigo, Katsuo Sugahara - Chromium is one of the most important elements that determine corrosion resistance of alloys in acidic solutions. Chromium is also the key alloying element to resist sulfurization and oxidation at elevated temperatures. A Ni-44Cr-1Mo alloy has been developed for applications in chemical process industry and coal fired coiler.

Kimberly Martinez, David Enos - Industry is being driven to adopt non-chromate conversion coatings (non-CCCs) as a replacement for chromate conversion coatings (CCCs) due to increasing regulation of hexavalent chromium.  For example, Europe's directive on the Restriction of Hazardous Substances (RoHS) is driving the elimination of hexavalent chromium worldwide and, as a result, industrial processes that rely on chromate will soon become obsolete.  As CCCs have been the standard for the corrosion protection of aluminum for decades, finding suitable replacement chemistries is of high importance.  While a wide variety of solutions are now commercially available, long term performance data for these materials is typically lacking.  Furthermore, the impact of secondary processing steps, such as thermal treatments associated with curing encapsulants and powder coatings, is poorly understood.  In this work, a series of commercially available non-CCCs were evaluated in terms of their co

Colton Spicer, Cameron Miller, John Wegand - The presence of rust staining on surface ship topside and freeboard areas has been a continuing cosmetic problem for the U.S. Naval Fleet.  In an effort to maintain the appearance of a well maintained ship, the U.S. Navy is estimated to expend more than $1.0M annually on silicone alkyd topside coatings, governed by Navy specification MIL-PRF-24635, purely for cosmetic over-coating purposes.  With the introduction of polysiloxane topside coatings, cleaning becomes a viable and more cost effective alternative to aesthetic re-coating due to polysiloxane’s superior color retention, gloss retention, and service life beyond the older silicone alkyd coatings. The focus of this paper will be on the investigation, development, and implementation of an effective corrosion stain remover that NRL conducted to reduce maintenance costs in the Navy associated with cosmetic over-coating and increase environmental compliance by reducing shipboard coat

Stephen LeBeau, Raymond Decker, Boyce Collins, Charles Sfeir - Magnesium alloys are gaining interest for biodegradable medical implant devices due to a good combination of mechanical properties and biocompatibility. Nevertheless, the fast degradation rates of magnesium and its biocompatible alloys in the aggressive physiological environment impose limitations on their clinical applications. This necessitates the development of magnesium based implants with controlled degradation rates to match the kinetics of the bone and tissue healing process and to avoid any complications or issues that might negatively impact surrounding tissues. The current study presents an overview of the application of alloy design and thermomechancial processing to optimize the mechanical and biological properties of a new proprietary Mg based alloy, BioMg 250.

Tim Burnett, Henry Holroyd, John Lewandowski, Mohsen Selfi - Investigation into the environmentally assisted cracking behaviour of AA5083-H131 has revealed two mechanistically different modes of crack propagation. Using a combination of high-resolution X-ray computed tomography and scanning electron microscopy (SEM) it has been possible to distinguish these distinct fracture modes from samples taken to failure in slow strain rate tests (SSRT) and also repeated tests that were halted just before failure. A range of sensitized AA5083-H131 round bar tensile specimens prepared in the short transverse direction were pre-exposed to 0.6M NaCl prior to testing. SSRT were conducted in laboratory air (50% RH) and very dry air. Intergranular stress corrosion cracking (IGSCC) was the crack propagation mechanism when the stress intensity factors remained in the range of 4 to 12-15 MNm-3/2.

Joao Salvado Azevedo - Concepts for “maintenance coatings”, “new construction” and “high durability” do not overlap in the offshore context. Maintenance coatings often do not aspire to “high durability” status while new construction processes, aspiring to such status, often fail to deliver such performance. The “high durability” aspiration, still, produces a divide between surface tolerant materials for maintenance operations and new construction coatings, driving the adoption of different material types, surface preparation methods and pre-qualification test protocols aimed at delivering an always illusive “high durability” performance. Facing this puzzle, four questions may come to mind of an optimistic coating formulator or a demanding offshore asset owner: 1) can a surface tolerant maintenance coating deliver high durability despite the less favorable conditions in which is applied? 2) if that is possible, could such tolerant coating technology be applied in a new construct

The methodology combines the use of field data and advanced modeling in a comprehensive approach. The first step of the method consists in collecting data on the structures using a combination of techniques such as half-cell potential and linear polarization. The field activities also include extracting cores from selected concrete elements. Samples from cores are tested to measure physical and chemical properties of the material. The data generated from the previous steps are used as input parameters in an advanced mechanistic chloride transport model to predict future performances of the structure. Depending on the results, different remediation scenarios can be modeled such as concrete repairs, sealer applications, and cathodic protection, and compared to

Jose Vera, Anchal Jatale, Mustafa Kara, Partha Sharma, Xiaoji Li, Mazdak Parsi - The rotating cage (RC) has been widely used for evaluating the performance of corrosion inhibitors in CO2 and H2S containing systems at high temperatures and pressures, under flow conditions.  The RC methodology has several practical advantages for assessing uniform and localized corrosion, and has shown to be a more stringent test than others typically used,  since some inhibitors (at a given concentration) loose effectiveness beyond a critical flow intensity.  Wall shear stress (WSS), which could be related to mass-transfer coefficient, is typically used to establish the appropriate RC velocity for simulating a field condition (e.g., pipe flow). The empirical equation included in ASTM G170-06 is commonly used for calculating the WSS of RC under homogeneous flow.  However, it has been shown using Computational Fluid Dynamic (CFD) calculations and experimental measurement that the WSS can vary signi

James Noland, David Comer, Parag Shah, Nigel Hilton, James Ondyak - It has been well documented that improved desalting efficiency reduces the risk of corrosion and vice versa.   The work life balance of the refinery corrosion engineer is frequently challenged by concerns that risk of overhead corrosion is increasing as refineries process more challenging crudes and run lengths increase.      One component of this problem is the risk of ammonia and amine salt formation.   As the concentration of the ammonia and amines increase, the risk of salt formation increases.  Computer modelling is employed to calculate this risk and to assure the selection of neutralizing amine used to control overhead pH does not also contribute to the risk of salt formation. Traditionally however, the natural level of ammonia and amines that are present in the system, meaning those not due to addition of the neutralizer, has been a “given” in the risk calculation.  They are typically monitored, but not c

The program under which this cerium-based sulfonated dichloro-diphenyl sulfone (SDCDPS) additive was developed originally targeted solutions for polymer electrolyte-based fuel cell membranes. It has since shown promise in effectively reducing the corrosion susceptibility of carbon steel substrates when added to urethane topcoats. Calcium salt of fatty acid sulfonates are commonly used corrosion inhibitors.  However, to gain effective inhibition levels, it requires higher concentration (more than 10 %) and is often challenging to formulate.  This is due to its inadequate compatibility with synthetic polymers such as epoxy and polyurethane.  In the case of cerium-based SDCDPS, ceria was complexed onto the sulfonic acid back bone to provide a novel option for additive based corrosion inhibition for solven

Helmuth Sarmiento Klapper, Elke Bozau, Anne Bartetzko, Joerg Lehr - Deep formation waters with high salinity and temperature, used for geothermal energy production, generally induce corrosion and scaling. Therefore, tailored material selection and costly chemical treatments are necessary to mitigate these. Technical facilities are adversely affected by corrosion and/or scaling, which significantly reduce their efficiency, resulting in profitability loss of the project. While monitoring corrosion and scaling directly in technical facilities increases their reliability and enables a more cost-effective use of chemical treatments, current commercially available monitoring systems are limited in terms of temperature and pressure.

A series of laboratory testing methodologies were conducted in order to further elucidate the factors which affect laboratory corrosion inhibitor performance in high temperature conditions. Under certain HT conditions, inhibitor performance may be skewed due to testing effects which may occur in closed cell testing at HT such as Fe2+ saturation and/or scaling of the test fluids which may artificially lower the overall general corrosion rate. This testing program was designed to minimize these effects and ensure that corrosion inhibition in laboratory testing is identified solely due to performance of the inhibitor. For these studies, corrosion measurements in stirred autoclaves were performed by linear polarization resistance (LPR) or with weight

Wells that have large amounts of carbon dioxide are extremely corrosive and normally thought to require continuous injection of inhibitor in all circumstances. In this paper experimental results on the effectiveness of these corrosion inhibitors are presented. The field performance of the inhibitors in wells where   the composition of carbon dioxide is as high as 95% will be presented. Use of batch treatment with th

Samin Sharifiasl, Ann Liang, David Cooke, Daniel Chapman, Benjamin Chaloner-Gill, Alexander Kuperman - Sulfidic corrosion of steels is defined as a high temperature (≥450oF) degradation phenomenon that occurs in oil containing sulfur species. Over the last few decades, many researchers have studied sulfidic corrosion; however, precisely predicting sulfidic corrosion rate is still a challenging task. In this work, the kinetics of sulfidic corrosion of carbon steel as a function of temperature, model sulfur compound concentration and test duration has been studied by the weight loss method. Hydrotreated vacuum gas oil (HVGO) was used as a solvent, and Dimethyl Disulfide (DMDS) as a model sulfur compound. DMDS is an ideal compound for this type of study, because of its high sulfur content (68%) and its decomposition temperature range of 360oF-450oF. It was found that the corrosion rate strongly depends on the concentration of sulfur species, temperature and time. The activation en

Mushaid Nauman, Roger King - Pipelines are energy lifelines, networks that deliver the nation's petroleum products within the country and across the borders. However, over the time these lifelines designed to operate reliably for 40 years or more do deteriorate. Detailed Integrity Assessment of one such veteran pipeline is carried out, having passed seven decades in operation while commissioned in 1945. This paper discusses the assessment challenges, inspection findings and recommendations given to keep this old offshore/onshore unpiggable giant in service for crude oil transportaion.  Using the complex geometry of the different pipeline sections (pigable and unpigable), ICDA and ECDA along with HAZID study have been modified for both offshore and onshore unpigable sections. ICDA methodology has been modified in view of environmental, operational and inspection data along with flow modelling study. The end result is a risk ranking of the pipeline sections susceptible to intern

Neal Berke, Kristin Ade, Peter DeNicola, Rungta Atri - Organofunctional silanes(OS) are increasingly being used to protect concrete bridge decks against chloride ingress and resulting corrosion. This paper describes the evaluation of the OS in mitigating ongoing corrosion due to chlorides or carbonation.  The procedure used for determining the mitigation of chloride-induced corrosion is a new Test Protocol M-82 developed by the U.S. Bureau of Reclamation in conjunction with the Strategic Development Council of the American Concrete Institute. The mitigation of carbonation induced corrosion was determined using a modified version of ASTM G109 in which the concrete was carbonated and then cyclically ponded with water.  The OS inhibitor was effective in mitigating both chloride induced and carbonation corrosion.  In the case of the chloride induced corrosion there was a reduction in additional chloride ingress.  Implications on the extended service life of treated structures is di

Jeremy L. Caron - N07022 is a Ni-21Cr-17Mo (wt.%) alloy that has found success in applications requiring corrosion resistance and high strength, which it achieves in the cold-worked condition.  The attributes of N07022 alloy make it an excellent candidate for many oil and gas applications.  It has been incorporated in the NACE MR0175 / ISO 15156 and NACE MR0103 / ISO 17945 standards at the highest test levels.  It has also shown resistance to the NACE Level VII environment with 5 g/L elemental sulfur at 205°C (401°F) and to the demanding conditions of 25% NaCl + 1,000 psi (6.9 MPa) CO2 + 1,000 psi (6.9 MPa) H2S at 288°C (550°F).  As higher strength alloys are becoming more common in high-pressure, high-temperature (HPHT) oil and gas service, there have been a number of reported failures involving precipitation-strengthened Ni-base alloys.  These failures were attributed to hydrogen embrittlement.  Recent results of sour gas and hydrogen embrittlement testing of cold-worked N07022

We have developed a computational design framework to predict in-service performance of corrosion-protective coating systems in order to accelerate the development cycle of new corrosion inhibitors. The framework converts multi-scale computational methods into functional materials design tools that can be linked through the molecular properties of chemical compositions to the engineering performance of the produced material system.

Yuan Ding, Bruce Brown, David Young, Marc Singer - In the present study, the effect of temperature on the adsorption kinetics and thermodynamics of diethylenetriamine talloil fatty acid imidazoline (DETA/TOFA imidazoline) is studied on a gold coated crystal using a Quartz Crystal Microbalance (QCM) in a CO2 saturated 1wt% NaCl solution. The corrosion inhibition performance of imidazoline on X65 steel is also investigated at different temperatures using Linear Polarization Resistance (LPR). QCM results show that the adsorption of imidazoline generally follows Langmuir adsorption process and the desorption of inhibitor is favored with increasing temperature. The desorption rate constant  is found to increase more with temperature than the adsorption reaction rate constant. Inhibition test results generally agree well with those obtained from QCM test and the loss of corrosion inhibition efficiency is attributed to the greater rate of desorption of inhibitor at higher temperature.

Therefore, higher level of quality is required for reduction of maintenance cost and long term service life time. In maintenance point of view, coating and surface preparation are very important factors. Especially, water soluble salts concentration on steel surface can significantly affect adhesion strength at the interface of steel and coating.   To study the effect of water soluble salts affecting long-term durability performance of carbon steels coated with epoxy paint, the carbon steel surface was contaminated by different soluble salt concentration. Based on NORSOK M-501 and ISO 20340 test method, sea water immersion test was carried out for 6 months and visual observation and pull off adhesion tests were conducted.

Masahiro Seto, Masayuki Sagara, Takahiro Osuki - Naphthenic acid corrosion is suffered in chemical plants at an atmospheric distillation unit, vacuum distillation unit and their surrounding equipments such as transfer lines and side cut pipes. The refineries for high TAN (Total acid number) crude cause the naphthenic acid corrosion of carbon steels or low alloy steels. In addition, naphthenic acid corrosion will be inevitable due to increasing of high TAN crude refineries by state-of-art crude refining technologies. Conventional austenitic stainless steels as 316L and 317L containing high molybdenum content are effective for naphthenic acid corrosion compare with carbon or low alloy steels. However, amounts of molybdenum of them are limited because of harmful influences on their metallurgical stability, formability, weldability and fablicability, etc.   In this paper, the effective elements such as molybdenum for resistance to the naphthenic acid corrosion are precisely conduc

Johannes Sonke - Application of effective Corrosion Inhibition (CI) in Oil and Gas production is needed to enable long-term use of Carbon Steels (CS) in corrosive systems. The CIs for these application need to be properly validated for the field exposures to assure operational integrity. It is thus essential to assure CI effectiveness within its needed Integrity Operating Window (IOW). CIs continue to change when facing challenges due to field maturation, new recovery approaches, and other like new field developments (e.g. higher H2S content). These needs have spurred new test protocol development. A range of CI test methods have evolved - some useful and others less so.

Ioan Pepenar - It is generally known that the steel in concrete is protected against corrosion due to the high pH-value of the pore solution of the concrete which leads to the formation of a passive oxide layer on the steel surface preventing its further corrosion. In the presence of an over critical chloride concentration in the concrete at the steel surface, this protective passive layer is locally destroyed (depassivation) and the steel corrosion starts. Therefore, understanding the mechanism of chloride induced breakdown of steel passive layer in concrete is significantly important in order to prevent the initiation of corrosion in prestressed concrete structures. The paper presents the results of research on the electrochemical behavior of prestressing steel in alkaline electrolytes, with various levels of chloride concentration by using cyclic potentiodynamic polarization technique. After each potentiodynamic polarization test which led to pitting corrosion, the steel sp

Takao Ohtsu, Masazumi Miyazawa, Kazutaka Akai, Hideaki Ootani, Ariyoshi Matsushige - The environments of chemical plant facilities are complex and multiple corrosion factors are frequently intermingled. When corrosion takes place, these factors interact and may camouflage the underlying causes of the corrosion damage, making it difficult to separate and elucidate them. However, in the continuous processing facilities, the time element is a useful additional factor that often can enable different corrosion phenomena to be tracked and their cause(s) identified. In order to take advantage of this situation, real time monitoring techniques are applied to clarify the contributory causes of corrosion attack that is sustained from time to time by the plant during normal operation. In this report of practical on-line monitoring, the use and benefits of the EN instrumentation, in combination with process chemistry analyses, were employed to monitoring operating conditions in a full-scale

Mon. 1 - 1:25pm Ernest N. Morial Convention Center-New Orleans - Symposia: Anodic & Cathodic Protection Assessment of Effects of Cavities and Narrow Channels on CP Design in the Marine Environment
Tim Froome - CP system design work in the marine environment makes use of structure surface area, required current density, and anode resistance formulae to select the number and mass of anodes required to protect a structure. The formulae cannot take account of restrictions to current flow caused by close proximity of structural surfaces to each other, and consequently CP systems which have been designed in the recommended way may sometimes not protect parts of a structure. In some situations it may be judged that cathodic protection is not required on some surfaces, but recommended practise is that current drain to such surfaces needs to be taken into account in the design. This paper first investigates the general effects caused when cavities and narrow channels/annuli are present, and attempts to identify patterns of behaviour. A series of computer-based parameter studies is performed in which, for example, separation between two structural surfaces is varied, and the extent

In Canada, the Canadian Energy Pipeline Association (CEPA), Petroleum Technology Alliance of Canada (PTAC), and the National Energy Board (NEB), have undertaken multiple studies to identify and assess the threats related to pipeline abandonment. The primary hazards typically identified across industry for pipeline abandonment are associated with long term corrosion degradation, potential for creation of water conduits, possible environmental impacts, and potential for pipeline collapse and associated soil subsidence. Unfortunately, little guidance is presently available to the industry for determining remaining structural capacity of a heavily corroded pipeline to establish likelihood, and possible timeline, of collapse, nor for determining possible subsidence magnitudes associated with

Due to a high Bottom Hole Temperature (~250oF) and moderate to high CaCO3 scaling tendencies, many wells have a strong tendency for downhole scale formation. More than 1000 wells are treated for scale/corrosion and to minimize the complexity of logistics and cost factors, the preferred control method is via the use of an innovative technology of encapsulated materials.  This material is applied downhole via batch treatments where it slowly dissolves offering long term scale or corrosion protection.  This paper will describe the management methodology that includes such factors as: statistical interpretation of the results, new laboratory method

Nevertheless commercially pure titanium may suffer localized corrosion in hot salty water ads well as acidic corrosion in fluoride containing solution or hydrogen embrittlement. Surface treatments, specifically anodic oxidation, has been considered to tune the TiO2 layer in order to increase its thickness and to obtain a mostly amorphous phase with the final aim to improve titanium corrosion resistance in highly aggressive environment.

The elastic moduli of  Ti67 and Ti3510 are closer to that of human bone ensuring a more equitable redistribution of mechanical stresses, thereby minimizing the phenomenon of stress shielding.  Direct and alternating current methods of electrochemical characterization were utilized to obtain insights into alloy behavior.

James Dante - It is becoming more widely recognized that current accelerated corrosion test exposures are insufficient for predicting corrosion behavior observed in operational environments. The result has been that promising technologies are rejected based on unrealistic failure modes and some material combinations that have been approved undergo critical failures during service. These challenges are proving to be a critical deficiency as new materials are sought to meet extreme operational needs and more stringent environmental requirements. To resolve these issues, this project seeks to develop a next generation accelerated corrosion test methodology that can be used to assess novel corrosion prevention technologies and quantify the performance of material systems. The method will incorporate representative environmental conditions, sample designs, and mechanical loading that replicate operational failure modes.

Martin Klein - Due to their low density, beneficial strength to weight ratio and good castability, magnesium alloys are very attractive for lightweight applications, e.g. in automotive industry. However, their application range is strongly limited due to their low corrosion resistance, especially in chloride containing electrolytes, which also impairs the fatigue properties under combined corrosive and fatigue load. For automotive applications, such as gearboxes and crankcases, materials have to withstand loadings at temperatures up to 200 °C, which additionally requires a good creep resistance. Currently available alloys for application temperatures up to 300 °C often contain rare earth elements as alloying elements and are therefore relatively expensive. As a result, extensive research has been carried out over the last years to develop creep-resistant magnesium alloys free from rare earth elements.

Ben-Hamu Guy - Replacement of bones by implants could solve major problems, after accidents, or because of aging. When traditional alloys are used as temporary implant devices, a second surgery is required to remove the implant after tissues have healed. Besides the cost of this surgical procedure and inconvenience to patients or risk for older patients, the traditional alloys also cause local inflammation due to potential release of cytotoxic ions. It would be very advantageous if an implant material could be identified that degraded in the physiological environment after completion of the healing process. Magnesium alloys are potential candidates for use as biodegradable temporary implant devices because they can naturally degrade in the human body environment due to their high electrochemical activity. There are many reactions that occur adjacent to the implant degradation in the body. One of these processes is Fenton reaction, common process in biological systems that is ca

Changing the functionality of DP from drilling operation to completion operation with early production in a subsea environment, requires a good critical analysis since the typical internal coating, designed for the mud abrasive and erosive actions, may not be suitable for exposure to the potentially corrosive production fluids. This paper presents failures of the internal coating of drill pipe riser (DPR) systems that operated during eight months in extended well testing (EWT) in Brazilian pre-salt fields at 1900 meters sea depth.  After two different EWT operations, blisters were seen through the internal coating of the tubes which had been in service.

Damián Vazquez - The reinforced concrete is one of the main materials used for the construction of facilities designed for the development of peaceful activities of nuclear energy. This material in addition to being structural, is a barrier for insulation and confinement of the radioactive materials. One of its degradation mechanisms is reinforcement corrosion, a frequent cause of failure in service. Consequently, it is essential to study this mechanism of degradation in formulations developed for this purpose, as well as the development and implementation of monitoring techniques for real structures.

Zhengwei Liu - The effect of corrosion coupon surface finishing processes on inhibitors’ performance was studied in CO2 environment. Two surface-finishing techniques, aluminum oxide beads blasting and sandpaper polishing, were used in this study. The resulting surfaces were characterized by white light interferometry and other techniques. The corrosion rate with and without the presence of corrosion inhibitors were evaluated using linear polarization methods. Several commercially available inhibitor products, including imidazoline, quaternary amines, phosphate ester, and mercaptans, were evaluated. It was found that the protection efficiency of mercaptans vary significantly with the coupons’ surface roughness.

Li Yan, Xin Pang, Muhammad Arafin, Sankara Papavinasam, Natashah Zaver - The regulation in Canada requires that starting from 2011 the renewable fuel content in diesel is at least 2%.  Similar USA requirements resulted in the production of more than 1.5 billion gallons of biodiesel in 2009.  Several other countries also produce large amount of biodiesel.  Two surveys were conducted in 2011 to understand the industry knowledge and experience with respect to the use of biodiesel. This paper summarises the salient features from these surveys.  This paper additionally focuses on material-biodiesel interaction at various stages between the production of biodiesel and usage. The main findings from these surveys include, Based on the experience gained so far, no major incident of material incompatibility with biodiesel of concentration up to 5% has been reported. Incidents of corrosion and microbiological influenced corrosion have been experienced in the presence of accumulated wat

Bei Wang, Lei Zhang, Qingping Li, liu yingkun, Wei Chang, Haiyuan Yao, Guang Chen, Yunan Zhang - With the development of the deep water offshore gas field in China recent years, long distance subsea gas pipelines have been built up and flow assurance becomes more and more important. The need to maintain gas production at reducing reservoir pressure had already resulted in much higher gas velocities in the field. However, higher gas velocity leads to higher wall shear stress that can be detrimental to the inhibitor adsorbing on the internal surface of pipeline, which will increase the corrosion risk especially for wet gas transportation. Corrosion is always recognized as one of the biggest flow assurance challenges of natural gas fields. During the pipeline design and maintenance, it is not enough to only use the equations of the limitation for the maximum erosional velocity from API RP 14E to deal with the balance of pipeline diameter, flow rate and the corrosion inhibitor film

Mon. 1:25 - 1:50pm Ernest N. Morial Convention Center-New Orleans - Symposia: Pipeline Integrity A Method for Assessing Facility Pipe Integrity
Daniel Fingas, Sorin Segall - In recent years, effective techniques have been developed for conducting integrity assessments along cross-country pipelines.  In order to provide similar confidence in facility integrity, it was proposed to apply a modified external corrosion direct assessment process to a small station.  Until now, congested facility environments have not generally been considered suitable for this approach because of the added complexity associated with electrically-continuous grounding and the large number of pipes and structures in close proximity. This paper describes the technical approach which was developed in order to overcome the expected challenges.  The conventional close-interval potential and direct current voltage gradient surveys were also enhanced to allow effective application in a facility.  These enhancements are described as they relate to a variety of common conditions, and guidelines for properly interpreting survey results in a station are

Douglas Gilroy - The measurement and interpretation of cathodic protection (CP) data in plant (i.e., complex) facilities present inherent challenges where mixed metals are electrically continuous with the protected structure.  Often there is no attempt to electrically isolate the on-plot buried steel piping networks from the facility for safety and practical considerations.  Coupons can be used to assist in the evaluation of CP levels on buried steel piping in mixed-metal circuits.  However, the present industry practice of disconnecting the coupon from the mixed-metal circuit to measure the potential and polarization, as described in NACE SP0104-2014 and BS EN 14505:2005, raises concern if the instant-disconnect condition is a true representation of the CP conditions.  Another common practice of not interrupting the CP current while measuring coupon-to-soil potentials is also a concern where closely coupled impressed current anode systems are installed adjacent to the buried pip

Hanne Martinusssen, Ingar Nerbø, Ole Eek, Harald Sleire - PipeMonit® is an ultrasonic erosion and corrosion monitoring tool which provides real-time and online wall thickness data for onshore and topside piping and pipelines. It is non-invasive and is installed and operated without interfering with production. Pulse-echo ultrasound monitoring provides fast and accurate erosion and corrosion rates, making it an effective tool for feedback of corrosion inhibitor programs. A 6 month trial of ultrasonic monitoring has been performed on an 8 inch OD pipeline in a gas plant. The ultrasonic monitoring system recorded measurements 4 times per day. In addition, manual Ultrasonic Testing (UT) was performed before and after the trial period. Comparison of the results showed that the manual UT measurements overestimated the corrosion rates by more than 100% compared to ultrasonic monitoring. During the trial period, a significant increase of corrosion rate was observed. The increased corro

Sridhar Srinivasan, Richard Horvath, Russell Kane, Kwei Meng Yap - This paper summarizes results from the third phase of the joint industry program (JIP) on refinery alkaline sour water (ammonium bisulfide) corrosion. Phase III included a comprehensive engineering analysis of data from all three phases of the Sour Water JIP and the development of “tie-in plots” based on a single variable (H2S partial pressure), replacing the widely used iso-corrosion diagrams developed in Phase I and Phase II. These tie-in plots enabled corrosion rate data to be contiguously modeled across the entire range of conditions tested (six orders of magnitude of H2S partial pressure – from approximately 0.00004 psia to 150 psia), characterizing effects of H2S-dominated, NH3-dominated and intermediate sour water conditions.  The results established that in addition to H2S partial pressure, NH4HS concentration, wall shear stress, and free cyanide concentration in the aqueous phase are the most significan

Ajit Mishra - Nickel-based alloys, containing optimum amount of chromium (Cr), molybdenum (Mo) and tungsten (W) are widely used in the chemical process industries due to their tolerance to both oxidizing and reducing conditions. Surprisingly, most of the corrosion data available in literature for the corrosion-resistant alloys (CRA’s) are in individual acids which seldom replicate the field conditions. Although it is not feasible to exactly reproduce the field environment in a laboratory set-up but a better approach, to understand the materials performance in field, can be by conducting the corrosion tests in both individual and mixed acids. One of the most commonly used technique by industrial researchers to determine an alloy corrosion performance in a corrosive environment is weight change measurement method. In the present study, corrosion tests were conducted using weight loss and electrochemical techniques for B-3 (UNS N10675), HYBRID-BC1 (UNS N10362), C-276 (UNS N10276)

Bai Cui, Xiaoxing Qiu, Fei Wang, Chenfei Zhang, Michael Nastasi, Yongfeng Lu - Fe- and Ni-based austenitic alloys, which are widely used in petroleum, chemical, and nuclear industries, are susceptible to stress corrosion cracking (SCC) in corrosive water environments. Laser shock peening (LSP) is a new approach that can effectively mitigate SCC of austenitic alloys, but the fundamental mechanisms by which this occurs remain poorly understood. In the LSP process, laser-driven shock waves are generated which can penetrate into the material, inducing significant compressive residual stresses and plastic deformation in a depth of more than 1 mm from the surface. In this study, LSP has been performed on 304 steels and oxide-dispersion-strengthened 304 steels. The microstructural evolution of austenitic alloys during the LSP process has been investigated by transmission electron microscopy, the effect of LSP conditions on residual stress distribution and SCC crack growth rate has been determ

Roland Oltra - Summary Eddy current probing has been tested to follow in real-time the intergranular damage of AA2024 thin foils in chloride containing media. In immersion conditions, it was demonstrated that the intergranular damage can be monitored on real-time during a corrosion test in potentiostatic conditions. The same approach was applied to corrosion in atmospheric conditions simulated by controlled salt spray experiments. The originality of this work is based on the use of very thin foils of AA2024  (30µm in thickness) combined with a commercial system (Z-Scope*7 from Sciensoria- France) which is a conventional EC nondestructive testing instrument covering a very wide frequency range (10 kHz-40MHz) developed for determining thickness and conductivity of thin foils.

Emily Hunt, Mike Baraky - Two types of corrosion cause the majority of problems in offshore or seawater applications. These are aqueous corrosion from the alkalinity of the seawater itself and degradation from microbiologically influenced corrosion (MIC). It is well recognized that an estimated 40% of all internal pipeline corrosion in the oil and gas industry can be attributed to MIC. In this type of corrosion, microorganisms in the seawater cause corrosion and stress cracking in both metallic and non-metallic materials. When this degradation is combined with aqueous corrosion from the marine environment, it is apparent that any significant advancement in MIC mitigation would prove invaluable to asset protection programs in these conditions.  RMB Products’ rotational lining solution can apply a thick, fully bonded, vacuum resistant, monolithic liner of high-density polyethylene (HDPE) to the inner diameter of piping systems.

Sigrun Karlsdottir - In recent years there has been an increased interest in drilling deeper geothermal wells to obtain more energy output per well with the corresponding higher temperature and pressure and increased corrosiveness of the geothermal environment. To explore the potential of the high alloy austenitic stainless steel UNS S31254 in future deep geothermal wells corrosion testing was done in simulated geothermal environment at 180°C and 350°C with a pressure of 10 bar. The simulated environment was composed of steam with H2S, HCl and CO2 gases, with a pH of 3 upon condensation. The testing was done in a flow through reactor for a 1 and 3 week exposures. The UNS S31254 performed well at 180°C with negligible corrosion rate both for the 1 and 3 week test and no localized corrosion damages were detected. Interestingly large NaCl were detected on the surface after testing. After the testing at 350°C localized damage were observed on the surface of the samples and substantia

Yao Xiong, Fang Cao, David Fischer, Jorge Pacheco - Oilfield facilities are handling far more complex conditions than what was required a few decades ago. Many existing fields are being operated way over their design life, and new developments are often in harsher environments. To manage safe and reliable operations in such environments, industry heavily relies on corrosion inhibitors to protect from internal corrosion. These chemicals are usually qualified and optimized in laboratories to ensure their performance. The laboratory tests, however, are typically conducted on freshly polished or machined coupons and do not reflect the scenarios for aged pipelines which had corrosion features established over the years. In this work, the impact of pre-corrosion on corrosion inhibitor performance has been investigated by corrosion testing and advanced surface analysis. Results show that the performance of corrosion inhibitors is significantly reduced after 3-day pre-corrosion due to t

Ivan Lasa, Mohammad Islam, Matthew Duncan -      The good performance of galvanic cathodic protection (GCP) systems is well proven and recognized for the protection of corrosion related damage on reinforced concrete (RC) structures located in marine environments. However, these cathodic protection systems are typically installed in areas where the concrete has a high chloride and moisture content.  It has been observed that typically in dry conditions, galvanic anodes either passivate or do not maintain a voltage potential sufficient to drive the CP current. On the contrary, for these dry areas, impressed current cathodic protection (ICCP) systems are preferred due to their higher voltages and their ability to force the currents.  This paper discusses the installation and performance of galvanic cathodic protection systems using pre-activated zinc anodes installed over dry concrete on bridges in Florida.

Jeremy Nelson, Michael Cayard, Joe Koerner, Anthony Gerbino - Typically alkaline carbonate stress corrosion cracking (ACSCC) is associated with fluid catalytic cracking unit (FCCU) sour water streams. While it has been recognized that ACSCC risks exist outside FCC sour water services, there have been few published cases of ACSCC in other locations. This paper highlights several cases where ACSCC occurred in atypical locations, including a cold wall FCC regenerator, sour water stripper (SWS) pumparound, SWS ammonia acid gas knockout, and a mercaptan oxidation unit. These unusual failure locations highlight the need for a fundamental understanding of the ACSCC mechanism. This paper discusses work done to monitor on-going ACSCC risks through sour water sampling, chemical analysis, and ionic modeling.

Suresh Divi, Vinay Deodeshmukh, Derek Spiller - Wrought, corrosion-resistant nickel alloys offer excellent resistance to hydrochloric acid. Of particular interest in this paper is the performance of various nickel-chromium-molybdenum and nickel-molybdenum alloys in concentrations >20% of hydrochloric acid below their boiling points. In this work, the corrosion resistance of N06022, N06200, N10276, N10675, and N10362 was studied in solutions of 20-37% HCl. The goal of this test program is to identify conditions resulting in corrosion rates close to 0.5 mm/y, the accepted maximum for industrial use. Based on the available data, an attempt was made to draw iso-corrosion lines of 0.5 mm/y for selected alloys in the range 20 to 37% HCl. Additionally, the corrosion performance of selected alloys (N10362, N06022, N06200, and N10675) was also studied by electrochemical polarization behavior.

Christof Langer, Michael Dornbusch - Based on the optical appearance and the good corrosion protection in the case of conventional corrosive stress, the industrial field of application for chromium-plated plastics is large. The multilayer system for corrosion protection consists of up to four nickel- and one chromium layer on the top, in which each nickel layer has a defined different electrochemical potential. This can be realized by an adjustment of the chemical composition of the electrolyte for galvanic deposition. Adding Sulphur containing brightening additives leads e.g. to a reduction of the electrochemical potential. Thereby, a defined difference in electrochemical potential of each layer can be generated. In state of the art systems, the bright nickel layer is the most ignoble layer. This leads to a corrosive attack in deeper layers, without changing the optical properties of the plating system.

Hans Husby, Roy Johnsen, Mariano Iannuzzi, Afrooz Barnoush, Mariano Kappes, Raul Rebak - Low alloy steels (LAS) are widely used in the oil and gas industry due to their excellent combination of mechanical and technological properties and cost. ISO 15156-2 governs the use of LAS in H2S containing environments, limiting the nickel (Ni) content to a maximum of 1 wt%. The effect of Ni on sulfide stress cracking (SSC) resistance was extensively investigated in the mid-1960’s to late 1980’s. Although most researchers suggested that Ni did not play a direct role in sour service performance, part of the engineering community has yet to reach consensus as to whether the cap on nickel was scientifically justified. Because Ni improves LAS hardenability and lowers the ductile to brittle transition temperature with a moderate penalty on weldability, qualifying LAS with Ni contents above 1 wt% would be a technology enabler in developing sour reservoirs with severe temperature and pressure conditions

This alloy displays the best known mechanical properties and corrosion resistance among the existing cast low carbon Ni-Cr-Mo alloys. This work reports on the properties achievable for a centrifugally cast low carbon 46Cr-35Ni-9Mo alloy tube of 4500 mm length and 55 mm wall thickness.

The influence of the various heat treatment states on the mechanical properties as well as corrosion resistance is studied. An extensive testing program has been taken for the determination of mechanical properties on samples taken from different orientations within the centrifugally cast tube. The properties do not exhibit directionality and hence demonstrate the isotropic behavior of the cast product.

It is used to determine metal loss In-Line Inspection (ILI) re-assessment interval, flag the high growth features that requires excavation before the next ILI and predict probability of failure of an unmitigated feature. Over-estimated CGR may result in unnecessary expenditures for excavations and remediation, while under-estimated CGR could result in pipeline failure.

Inhibited acid cleaning was carried out to remove the hard scales from the chokes’ beans and sections of the flowlines for wells having significant scale accumulations.   Online internal corrosion monitoring coupons were installed on the flowlines to monitor internal corrosion during acid cleaning and routine operation. Similarly, scale coupons were installed to evaluate scale inhibitor efficiency. Fluid sampling was carried out during acid cleaning to check dissolved iron (Fe) content as corrosion monitoring indicator and scaling tendency. Rad

Yun Soo Lim - Ni-based Alloy 600 (16wt%Cr-8wt%Fe), which has been used extensively for structural components in nuclear power plants, is well known to be highly susceptible to primary water stress corrosion cracking (PWSCC) in the primary side environments of a PWR. Another Ni-based Alloy 690 (Ni–30wt%Cr–10wt%Fe) has become a substitute for Alloy 600 owing to its excellent mechanical and corrosion properties. The predominant failure mode of Alloy 600 by PWSCC is known to be mostly intergranular SCC (IGSCC). Although the exact failure mechanism involved is still not well understood, there is currently rising evidence to support intergranular oxidation, in which oxygen diffusion into the grain boundaries can increase the degree of susceptibility to PWSCC. As a result, intergranular oxidation is responsible for grain boundary embrittlement, and therefore has a major contribution to IGSCC. The aim of the present study is to investigate the resistance of Alloy 600 and Alloy 690 to PWS

Karl Vidic, Gregor Mori - Automotive exhaust components have to ensure reliable performance under aggressive environmental conditions. Operating temperatures up to 900 °C, wetness and the attack of chloride‑containing de-icing salts make extensive requirements to the service life of the parts. The corrosion resistance of one ferritic stainless steel against the attack by dry, chloride‑containing alkali salt, which is deposited on the metal substrate, has been investigated by means of isothermal exposure tests in different atmospheres. Under field conditions dynamic and simultaneous variations of environmental factors influencing corrosion occur and the detailed examination of particular factors is hindered. To guarantee separate quantification of those factors an experimental plan has been established. Two layered samples, consisting of an inner steel sheet and an adjacent, salt contaminate insulation mat have been tested. To quantify the corrosive effect of dry salt deposits,

Shyama Ranade, YongJun Tan, Maria Forsyth - Coatings form an integral part of the corrosion protection system of oil and gas pipelines. It is necessary to assess and analyse the coatings for loss of integrity such as mechanically induced holidays and cracks before they are put into operation. The standard method of assessing coating’s behaviour and flexibility under mechanical strain is the mandrel bending test, wherein high voltage holiday test is normally used to determine the existences of discontinuities in coating films. A limitation of the holiday detector is that it can only detect coating defects ex-situ, i.e. after mandrel bending. A new experimental method has been proposed to perform in-situ measurement of the loss of coating integrity under the effect of combined mechanical strain and environmental exposure. The experimental setup consists of a small scale tensile rig capable of applying a mechanical strain, coupled with an electrochemical cell that is used to expos

The mechanistic information was obtained employing such electrochemical techniques as linear polarization (LPR), electrochemical frequency modulation (EFM) and potentiodynamic polarization while using a rotating cylinder electrode (RCE) system under CO2 corrosion conditions. The employed electrochemical methods allow determination of anodic, cathodic or mixed corrosion inhibition mechanisms.

Tina Tajalli, Cathleen Shargay, Karly Moore, Lionel Roberts, Jonathan Allen - Stress corrosion cracking (SCC) is one of the most prevalent root causes of stainless steel failures in the refining industry. This paper focuses on the risks of polythionic acid (PTA) and chloride SCC, and reviews the risks from both internal process services and from external atmospheric and/or wet insulation conditions. Steps can be taken to mitigate the risk of SCC, but since changes in the process or external conditions can occur over time, periodic unit reviews are beneficial. This paper also discusses setting the risk-based inspection ratings for these possible damage mechanisms, and suggested methodologies for determining these risk ratings. These methodologies are complimentary to the recommendations given in API RP 581, “Risk-Based Inspection Technology” and this paper gives separate review steps for the internal and external risks.

Fangxin Zou - There exist many well-established techniques for corrosion monitoring. These include, but are not limited to, weight measurements, linear polarisation resistance (LPR) measurements and tactile measurements. However, all of these approaches are not easy to apply to fluid conduits in the field since they require access to the interiors of components. Also, weight measurements and LPR measurements are only capable of determining mass loss rates. The corresponding calculation of wall thickness losses requires integration and the assumption of several parameters such as the area over which the measurement is taking place.             Ultrasonic measurements, which can be carried out from the exteriors of components, are much more field-deployable. It has been demonstrated that by using permanently installed transducers, a precision in the order of micro-meters in wall thickness measurements can be achieved. This means that for corrosion rates of the order of 0.1 mm/year

Marco Ormellese, Andrea Brenna, Silvia Beretta, Fabio Bolzoni - Usually cathodic protection (CP) is continuously applied to control corrosion of buried pipeline. The effect of cathodic reactions (oxygen reduction and/or hydrogen evolution) taking place on the metal surface is twofold: oxygen consumption and alkalization (pH > 10) at the metal-to-electrolyte interface leading carbon steel to work in passive condition. Aim of the research is to exploit the chemical and electrochemical condition at the metal interface to apply an intermittent CP: during the ON period oxygen is consumed and alkaline pH is established, during OFF period, the alkalinity produced in the previous phase assure passive condition until neutral condition re-establishes, then CP is switched on again. Test has been performed both in normal and overprotection condition, varying the duration of the on and off periods (6 h, 12 h and 18 h), monitoring weekly the protection potential and the protection current.

Corrosion of the steel reinforcement during the corrosion propagation was monitored on selected laboratory specimens for several years.

An electric field was applied to drive the chlorides and reach the rebar depth until it exceeded the chloride threshold. Linear polarization tests have been monitored for over 3 years on eight specimens, and for a shorter period (approx. six months) on six other specimens. The proposed study will assist in providing the Florida department of transportation with guidance as to how fast the corrosion rate will be at various chloride concentrations for rebars embedded in concrete.

Geraint Williams, Alex Nielsen, Nathan Cooze, Hamilton McMurray - Title: Atmospheric corrosion of brass under sodium chloride-containing water droplets studied using a scanning Kelvin probe Abstract: It is well known that during the atmospheric corrosion of certain metals such as iron and zinc, a differential aeration cell becomes established within a salt-water droplet [1 - 3], giving rise to the evolution of a secondary spreading phenomenon beyond the physical confines of the original droplet. The secondary zone is produced by cathodic oxygen reduction originating at the perimeter of the droplet, which in turn draws sodium ions and associated water from the droplet bulk. Thus, a thin electrolyte layer composed of dilute aqueous sodium hydroxide surrounds the primary droplet and grows radially with time. In this work a combination of in-situ, height-regulated Scanning Kelvin probe (SKP) potentiometry and time-lapse photography is used to characterise the evolution of localise

V S Raja, Mangesh Pustode, Anup Panindre, Ajay Krishnan - Film damage to induce and propagate stress corrosion cracking of metallic alloys has been widely reported in the published literature, though there is still disagreement on how the film damage leads to stress corrosion cracking and brittle fracture. Thus, the crack growth mechanism due to the slip assisted dissolution differs from that of the film induced cleavage. Interestingly, in our study we have found that the stability of the oxide films greatly influences hydrogen embrittlement of the alloys of two very reactive metals namely magnesium and titanium. As they form thick oxide films, hydrogen entry into these two alloys is significantly lowered. Our studies show that there is a need to damage the oxide films of these alloys through chemical species such as chlorides for rendering these alloys susceptible to hydrogen embrittlement.

But the electrodes in monopolar modes may introduce DC interferences on buried metallic pipelines nearby, and increase the risk of corrosion and hydrogen embrittlement. Focusing on a real case of HVDC interference, this paper aimed to study the field test, the numerical simulation calculation, and the design of mitigation. Firstly, field tests found that a natural gas pipeline system was interfered by a HVDC electrode system in Guangdong province. The pipe-to-soil on potentials along the pipe had deviations up to 300V, posing severe threats to safety operation of the pipeline system. Then, the numerical simulation technique was used to model the electrode and pipeline system based on field parameters. The interference level was computed and the results showed good agreements with the measured values, which indicated the validity of the model. Finally,

Continuous downhole injection of chemicals is increasingly required to manage challenges, such as scale formation and corrosion within the wellbore completion components. Many challenges are met when designing and qualifying chemicals for continuous downhole injection via capillary line. Discussed herein are the physical properties production chemicals injected via capillaries should possess including temperature stability, gunking, compatibility with process fluids, and efficiency.

Fujian Tang - Use of optical fiber sensors to monitor steel corrosion has attracted a lot of interests in the past two decades, due to its small size, high precision and stability, electromagnetic immunity, possibility of being employed in large structures. In this study an optical fiber corrosion sensor is developed to monitor the growth of corrosion pits in steel bars in chloride-laden concrete environment. The sensor was simply made by encasing one end of an optical fiber into a steel straw. As the corrosion penetrates through the steel straw wall, the corrosive solution and corrosion products fill in and contaminate the fiber end surface, resulting in a change in the reflectivity. The change of the optical fiber reflectivity indicates the corrosion pits depth equaling to the straw wall thickness. Therefore, by deploying corrosion sensors with different wall thicknesses in concrete structures, the corrosion pit depth at different time periods can be monitored. The steel straw

Jayant Nair, Fahmi Al Mawali, Naif Abri, Asad Al Ghafri - Residue Fluid Catalytic cracking (RFCC) is a valuable subset of the more conventional Fluid Catalytic cracking (FCC) process which generates most of the world’s gasoline pool. The critical distinction of RFCC involves the processing of “dirty” atmospheric residue (AR) directly from crude distillation and not just the more conventional use of relatively pure gasoil feedstocks. By direct catalytic cracking of “dirty” residue the refiner benefits economically by avoiding a whole intermediate process, namely vacuum distillation. Unfortunately direct FCC processing of atmospheric residue (AR) exposes the vessel internals to geological salts naturally present in crude oil but concentrated in the residue fraction during the distillation process.

Kathy Zhang - Assessment of fatigue crack growth for pipelines is critical to evaluate the effects of operation pressure acting on flaws and predict the remaining service life. Under pressure cycling, the crack propagates continuously until it reaches a critical size, resulting in pipeline leaking or rupture. For most fatigue growth models, relatively little attention has been paid is the effects of crack shape or aspect ratio on crack growth behaviors. This may result in less reliable results and thus potentially leads to an unrealistic integrity management and maintenance.  As such, developing a fully understanding of crack shape development during crack growth and estimating remaining life can be very important. In this work, the development of crack aspect ratio (crack depth/half-crack length) was studied for semi-elliptical surface crack for pipelines undergoing pressure cycling.

Amirhossein Foroozan Ebrahimy, Anatolie Anatolie Carcea, Roger Newman - Passive alloys in the NiCrFe system are normally protected by a Cr-rich oxide film. Exposure to environments containing reduced S species can result in rapid corrosion or cracking, mediated by adsorption of S on (mainly) the Ni component. This catalyzes the dissolution of Ni, removing whatever inhibiting effect it had on the dissolution, and undercutting the Cr-rich oxide. Dissolution of Fe is also catalyzed [1-4]. First-principles calculations confirm that adsorbed S in hollow sites on Ni surfaces reduces the electron density between surface Ni atoms, providing a transparent explanation for the catalysis of anodic dissolution [5, 6]. In high-temperature, high-pressure aqueous solutions, reduced forms of sulfur continue to act aggressively towards NiCrFe alloys, but additional possibilities arise – Sulfate reduction, on metal surfaces and/or catalyzed by specific minerals, perhaps involving hydrazine in b

While explicit models are available for the individual analysis of corrosion and dent features, there is significant room for research and development in the assessment of these features when they interact. Additionally, the uncertainties associated with the input variables (such as in-line inspection measurements, pipe attributes, operating conditions, etc.) are often neglected or considered within a limited scope in the analysis methods typically being implemented in the pipeline industry today.

This system delivers the continuous wall thickness measurements to the corrosion engineer’s desk so that corrosion events are detected and monitored in real time while the process units are in operation.  Recent advances in processing, visualisation and analysis of the data delivered by the corrosion monitoring system have afforded previously unavailable insights into when, where and why corrosion has occurred in the refinery’s process units. In particular, the additional insights delivered has enabled this refiner to correlate very small changes to the internal surface condition – the o

Mon. 4:30 - 4:30pm Ernest N. Morial Convention Center-New Orleans - Symposia: Anodic & Cathodic Protection Protection of Deep Sea Steel Structures Using Thermally Sprayed Aluminium
Shiladitya Paul - Thermally sprayed aluminium (TSA) has been used in offshore applications for decades. Their effectiveness in mitigating corrosion of steel structures in presence of seawater has been proven over the years. However, very little work is reported on the performance of TSA when damaged. Furthermore, data on the performance of damaged TSA in deep sea is virtually non-existent. The paper addresses these knowledge gaps and reports the corrosion performance of damaged TSA in a simulated deep sea environment. Holidays amounting to 3% of the sample area were drilled to expose the underlying carbon steel and the sample was exposed to synthetic seawater at 5°C in an autoclave at 50MPa to simulate 5000m of water pressure. After testing, examination of the sample revealed the formation of calcareous deposit on the exposed steel surface with no visible steel corrosion product. Detailed microstructural characterisation of the calcareous deposit confirmed the formation of prot

Mon. 5:05 - 5:30pm Ernest N. Morial Convention Center-New Orleans - Symposia: Novel Methods of Corrosion Monitoring and Management Steel Corrosion Monitoring in Concrete Slab Using a Long Period Fiber Grating Assembly
Fujian Tang, Yizheng Chen - Steel corrosion in concrete structures is a slow process that usually takes several years to a degree that induces concrete cover cracking, and the corrosion amount or the penetration depth is hard to detect due to the presence of concrete cover. Long period fiber grating (LPFG) couples incident light from propagating core mode to co-propagating cladding mode, producing a series of attenuation bands of transmission spectrum. The resonant wavelength of the spectral attenuation bands is closely related to the effective refractive index of the medium surrounding the fiber gratings. As the chemicals in the surrounding medium change, the resonant wavelength is shifted. Therefore, it is widely used for physical, chemical and biochemical sensing.   In this study a corrosion sensing assembly to monitor steel bar corrosion in concrete slab based on the LPFG sensing principle is proposed and its performance is experimentally investigated. The assembly was made by

Ruth Wardman, Tom Champlin, Kevin Clarke, Sam Lordo - Safe processing of Naphthenic acid opportunity crudes using a combination of chemical corrosion inhibition and online continuous corrosion monitoring. Continuing economic pressures on the refining industry are forcing more refiners to evaluate the possibilities of processing lower priced, opportunity naphthenic acid crudes in order to improve margins. The processing of naphthenic acid crudes introduces significant challenges to the refiner, with the risk of high temperature naphthenic acid corrosion being one of the primary concerns. If refiners are to take full advantage of these discounted opportunity crudes, these challenges need to be addressed in order to avoid margin attrition caused by decreased equipment reliability and run length. Refiners must assess, monitor and mitigate naphthenic acid corrosion and other processing impacts associated with these crudes. One of the most critical aspects of this risk management m

Tue. 8 - 8:25am Ernest N. Morial Convention Center-New Orleans - Symposia: Corrosion Solutions for the Chemical Process Industry with Polymer Based Materials Using Ultrasonic Technique to Determine Fitness for Service of FRP Equipment for Chemical Handling A
Pradip Khaladkar - Fiberglass reinforced plastic materials are well suited to a wide variety of chemical handling equipment where resistance to corrosion is required.  A significant impediment to adoption of these materials for many suitable applications lies with the inability to do a fitness for service determination after the equipment and piping have been in service.  This is largely due to the lack of effective non-destructive and non-intrusive techniques for plastic materials. This paper presents a case study of a fiberglass reinforced plastic scrubber which was evaluated with a novel ultrasonic technique followed by a destructive evaluation for retained mechanical properties.  The results were compared which indicated a good correlation. Although the FRP unit was already discarded this study indicated that significant life had still remained.

Andrea Sanchez, Alberto Sagues, Michael T. Walsh - The potential of passive steel embedded in concrete is a key parameter on the value of the chloride corrosion threshold. The phenomenon of a potential-dependent chloride threshold (PDT) together with corrosion macrocell coupling between active and passive steel assembly components needs consideration in corrosion forecast models for reinforced concrete structures in marine service. Initial deterministic corrosion initiation-propagation models incorporating PDT projected much lower damage development in an aged system than when using the traditional potential-independent chloride threshold (PIT) assumption. In contrast, for early stages of corrosion damage the relative effect tended to be in the opposite direction. These diverse outcomes are explained by the interplay between delayed corrosion initiation and concentration of corrosion when it is localized. An expansion of that PDT forecast model case is presented here using advanc

Chukwuma Onuoha, Shamus McDonnell, Lloyd Oscar de Guzman, Robert Lennox, Eric Pozniak, Greg Zinter, Parth Iyer, Yoko Nakazato, Corina Blaga - Direct Assessment (DA), Inline Inspection (ILI) and hydrostatic testing (HT) are primary inspection tools acknowledged globally as approved pipeline integrity inspection techniques. These techniques have their merits and demerits, and each reflects a different, unique aspect of the overall integrity of the pipeline. Therefore, an integrated approach that would combine ILI and DA techniques would provide comprehensive pipeline integrity management program for pipeline operators. This paper will provide comprehensive correlation of inline and aboveground pipeline integrity data geared at ensuring overall pipeline integrity management program. ILI tools are designed to inspect the conditions of the pipeline wall with limited disruption to operations. These tools are used to identity and quantify the risk of corrosion, dents and cracks.

Jon Kvarekval - An experimental study of corrosion of carbon steel in the presence of H2S, CO2 and acetic acid has been carried out. H2S and CO2 partial pressures up to 10 bar each were applied, with temperatures of 25 and 90 deg C. The test solutions consisted of high-salinity brine (100 g/L NaCl, 150 ppm bicarbonate) and low-salinity condensed water (0.1 g/L NaCl). The duration of the tests was around 14 days. Both weight loss corrosion and localized corrosion data were obtained. The entire surfaces of the exposed coupons were scanned with a 3D profilometer, obtaining detailed data on localized corrosion morphology, pit frequency and pit depths. The results are discussed on the background of previous findings and available literature.

Charles Marks, Marc Kreider, Jean Collin, Joshua Luszcz - Initial operation of a wiped-film evaporator used in a power plant installation for waste processing led to high levels of fouling with calcium-containing particulates on various components inside the evaporator.  These fouling deposits cause reductions in evaporator thermal efficiency and availability and an increased risk of personnel contamination with airborne particles during periodic maintenance activities.  Initial attempts to remove these deposits using water-jet and manual cleaning were very labor intensive. As an alternative, the authors developed two customized, complementary cleaning systems based on the use of ultrasonic technology to remotely remove the fouling deposits.  The first system, consisting of multiple ultrasonic transducers mounted on the exterior of the evaporator shell, is designed to operate continuously online during evaporator operation (limiting deposit buildup in a critical location within

Li Yan, Jean-Philippe Gravel, Luyao Xu, Jidong Kang, Muhammad Arafin - Cathodic protection (CP) in conjunction with coating is generally recognized as the most effective mitigation method for pipeline external corrosion and stress corrosion cracking (SCC). However, if not designed properly for a given pipeline system, the applied CP can cause detrimental effects instead such as coating disbondment leading to corrosion and SCC, hydrogen induced cracking (HIC) or hydrogen embrittlement in general. It has been recognized that modern high-strength pipeline steels can be more susceptible to hydrogen embrittlement or related environment assisted cracking such as near-neutral pH SCC compared to their low-strength steels counterparts. However, the role of CP in the prevention or facilitation of such cracking is still not clear. The objective of this study is to examine the effect of CP on the initiation and propagation of SCC in two different high strength pipe steels, namely X80 and X

Sinuo Lang - Self-healing coatings have been promising due to its automatic recovering functions, which can extend the coating lifetime with lower maintenance costs. One of the most effective strategies to achieve the self-healing property is to encapsulate healing agents inside microcapsules and integrate the microcapsules into the coating matrix. In this study, linseed oil was successfully encapsulated in poly(urea-formaldehyde) (PUF) shell via in-situ polymerization. Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA) were used to characterize the chemical composition of the synthesized microcapsules. The size and morphology of the synthesized microcapsules were observed with both optical microscope and scanning electron microscope (SEM). The effects of the molecular weight of poly(vinyl alcohol) (PVA) stabilizers, stir rates, and reaction temperatures on the property of microcapsules were investigated.

Zheng Ma - Electrochemical Quartz Crystal Microbalance (EQCM) is a very accurate in-situ mass change measurement device. Besides the ability of monitoring the in-situ mass change in high resolution (on the scale of nanograms), the EQCM also allows to conduct electrochemical measurement simultaneously. In this work, the EQCM has been used to investigate the kinetics of FeCO3 precipitation in an aqueous CO2 corrosion environment. Three different substrates were used to conduct the FeCO3 precipitation experiments: gold-coated quartz crystal with cathodic polarization, iron-coated quartz crystal with and without cathodic protection, at varied system temperatures (60°C-80°C). Precipitation rates of FeCO3 obtained by using EQCM were compared with calculations using a model developed by Sun and Nesic in 2008 and a good agreement was obtained.

A failure analysis was carried out including non-destructive and destructive tests on received tubes. Feedwater, drum water and live steam qualities were evaluated based on plant authority provided data. The results obtained through this study indicate a mechanism of caustic gouging inducing hydrogen Embritlment. The root causes determined were improper carryover control, and waterlines creation by low flow and/or high blowdown rate. Therefore, it was recommended to conduct a total inspection of the boiler to determine the extent of damage. As preventive maintenance, a more strict control of the carryover is necessary through the monitoring of sodium/phosphate ratio, reduction in the oxygen allowed level, fixation of the chemical boiler treatment dozing problems.

Zitao Jiang, Yanxia Du, Xiuyun Wang, Caigang Ge, Guofei Cao, Qinglin Gu - While the high voltage direct current (HVDC) system runs in monopole-ground mode, thousands of amperes direct current will flow into earth through its earth electrode. This current may cause serious interference on buried pipeline even though it is far away from the earth electrode. Field testing results indicate that this interference may arrive beyond one hundred kilometers, and induce hundreds of volt interference potential on the pipeline. In this work, numerical simulation were used to study the mechanism of HVDC interference and analyze influencing factors. The results indicated that while a large direct current flowed into the soil, it could create a strong electric field and induce serious interference on the pipeline. In addition, influencing factors study indicated that the better the pipeline coating was, the higher interference the pipeline suffered from. Soil structure and soil resistivity ha

Atef Cheaitani - Impressed current cathodic protection (CP) for reinforced concrete structures is a proven technology which can provide long term corrosion prevention for marine structures if properly designed and installed. This technology has been applied to large a number of concrete structures in Australia over the past 30 years and it is the technology of choice for many asset owners for the protection of structures susceptible to chloride induced corrosion. While this technology has proven to be highly effective in providing corrosion protection to embedded steel reinforcement, in some cases, the maintenance and monitoring costs have been relatively high and this is often due to defects during the design and construction stage of the system. The review of performance of many operating CP systems in Australia has led to the conclusion that there are many areas of improvement which can be implemented to optimise the long term performance of impressed current CP systems.

Jiheon Jun, Gerald Frankel, Narasi Sridhar - The initiation, growth and repassivation of localized dissolution on Super 13Cr stainless steel (S13Cr) was studied using one-dimensional (1D) pit electrode in 0.3 and 3 M NaCl solutions for 10% H2S + 90% N2 or 100% N2 gaseous condition at 85 °C. The breakdown potential for the initiation of localized dissolution on S13Cr decreased by increasing NaCl concentration and adding 10% H2S. For the 10% H2S condition, a current increase associated with H2S oxidation was observed around -0.3 VSCE prior to passivity breakdown in both 0.3 and 3 M NaCl. The dissolution current of S13Cr 1D pit under potentiostatic polarization was comparable to transport-limited current after achieving pit depth larger than 300 um. The 1D pit dissolution current was higher in 0.3 M than 3 M NaCl, but it was not influenced by 10% H2S. A backward potentiodynamic scanning was then applied on a growing 1D pit to monitor current decay associated with deactivation/repa

Behzad Bavarian, Lisa Reiner - Corrosion is one of the primary concerns in the durability of materials and structures. Research efforts have been made to find a corrosion inhibition process to prolong the life of existing structures and minimize corrosion damages in new structures. Migrating Corrosion Inhibitor technology was developed to protect the embedded steel rebar/concrete structure. These inhibitors are based on amino carboxylate chemistry and the most effective types of inhibitor interact at the anode and cathode simultaneously. These inhibitors use compounds that work by forming a monomolecular film between the metal and the water. In the case of film forming amines, one end of the molecule is hydrophilic and the other hydrophobic. These molecules will arrange themselves parallel to one another and perpendicular to the reinforcement forming a barrier. Four types of reinforced concrete samples were prepared, control, soda ash added, and inhibitors added. Two admixture

Tony Zacharewych - FRP pipe systems that are designed to meet rigid specifications should be tested to prove that they will perform accordingly. FRP pipe systems are used for severe corrosive and erosive process streams and customers need peace of mind in knowing their design has been properly validated. ASME B31.1 “Power Piping” references ASTM D6041 that is a standard specification for contact molded pipe and fittings, and includes requirements for materials, design, and proof testing. Testing a typical fitting such as an elbow or reducer would involve pressure testing with ambient temperature water to four times the rated pressure for one hour without leakage. This paper will review what is required by ASTM D6041 as well as give an overview of our recent program to develop and proof test 290 psi (20 Bar) pipe, fittings, flanges, and laminated joints. - Tony Zacharewych P.Eng

Sumanth Cheruku - Service life estimate presents the owner with an outline of when the structure would require a corrosion related repair. This provides an owner with an option to prepare a budget plan to support future repairs and its acceptance in the industry is essential. Present service life estimates include a single value (usually the number of years) with rarely considering the uncertainty associated with each parameter in the estimation process.  The exclusion of this uncertainty induces a chance for early failure, which is a more critical case, leading to the owner hustling to accommodate the budget for early repair. The paper intends to walk through the service life estimation process for chloride-induced corrosion in reinforced concrete structures highlighting the uncertainty associated with each parameter including the use of closed-form solution for Fick’s Law, ASTM process for estimation of diffusion coefficient, the influence of new reinforcing steel and new adm

Li Yan, Jean-Philippe Gravel - The most effective method to mitigate corrosion on the external surface of a buried pipeline is to utilize a protective coating supplemented by cathodic protection (CP). Ideally, these two systems work together so that if the coating disbonds or has defects allowing ground water solution to contact the pipe steel surface the CP system will continue to function to protect the pipeline. However, the success of this approach greatly depends on the nature of coating failures. CP can only provide corrosion protection to the pipe with coating failures if sufficient CP current is able to reach the exposed pipe steel. For instance, if CP current can penetrate into a coating disbondment, then corrosion related damages may be prevented. Otherwise, the exposed pipe steel could be susceptible to corrosion and environmentally assisted cracking. Due to this very reason, disbondment of pipe coatings, especially, coatings with high impedances is considered to be

John Richardson - Scale deposition on heat transfer surfaces can seriously affect steam generation in modern boilers. Deposits can lead to a loss of efficiency, serious corrosion, short and long term overheating problems, and ultimately tube failures. Plant profitability and production losses generally cannot be recovered when tube failures occur. Production losses resulting from reduced steam capacity are far greater than the actual repair and maintenance costs incurred during the shutdown. The major problems associated with deposits and scale are corrosion and overheating. Control of iron oxide deposits by using specific polymers is key to maintaining clean heat transfer surfaces and generating passive films within an industrial boiler. This paper will focus on mechanisms that jusitfy this application.

Teresa Perez - Corrosion resistant alloys (CRA) and carbon and low alloyed steels used in the upstream oil and gas industry may be susceptible to localized corrosion. Several variables control the occurrence of localized corrosion in CRAs, including alloy composition, heat treatment and environmental effects such as temperature, chloride and other chemical species. Regarding carbon and low alloyed steels, it is recognized that even small concentrations of H2S can have an important effect on general corrosion rate when compared to environments where CO2 controlled the corrosion phenomenon. However, there are still a number of unknowns about the effect of H2S on pitting, which is the most common mode of sour service failure. The purpose of this review is to discuss the environmental effects, especially of hydrogen sulfide and carbon dioxide on pitting susceptibility of CRAs and low alloyed steels.

Sujay Math, David Kroon, Dale Lindemuth, Rick Kimpel - Trench breaker foaming systems are temporary or permanent barriers installed in pipe trenches at regular intervals to prevent trench collapse. The ability of the foaming systems to conduct or shield cathodic protection current has not been extensively studied. Investigations were conducted on trench breaker foams to understand the ability of the foaming systems to conduct cathodic protection (CP) current on an underground pipeline. Two different types of foams, open cell (low density) and closed cell (high density), were used. The testing was conducted on two FBE-coated pipelines buried in a trench with various foaming system combinations applied as breakers. Coating defects (holidays) were created at known locations on the pipeline by disrupting the coating; reference electrodes and electrical resistance (ER) probes were installed at the coating defect locations. Trench breaker foams were sprayed to embed the holidays, refer

Dewan Hossain, David Garber, Kingsley Lau - Premature strength deterioration of concrete structures caused by steel reinforcement corrosion is a concern. The presented work represents results from an experimental investigation involving testing of small scale reinforced concrete and prestressed concrete beams to correlate steel corrosion to global strain changes in the beam. Concrete beams (4inch x 4inch x 15inch) with reinforced and prestressed wire were used in aggressive corrosion environment to accelerate steel cross-section loss. Electrochemical polarization techniques was used to control and measure steel corrosion activity. The mechanical performance of the beam initially loaded in flexure considered linear elastic behavior, but testing to beam failure was also conducted. The strain profile of the loaded corroding beam was monitored by surface strain gauges at the extreme fiber and intermediate beam depths. The test results obtained from the experimental work were furthe

Lei Zhang - With the more widely application of pipeline steels higher than API X80 grade, the hydrogen embrittlement risk induced by negative cathodic polarization and hydrogen evolution effect under cathodic protection has been recognized. Since the strengthening of pipeline steel might significantly increase the hydrogen cracking sensitivity, more understandings on the different criteria of cathodic protection potential or current density compared with those of traditional pipeline steels are requried. This paper focuses on the hydrogen embrittlement behavior of API X70, X80 and X90 high strength pipeline steel under cathodic protection in soil simulation conditions. The uptake and diffusion of hydrogen in the steels under different cathodic protection level were analyzed by hydrogen permeation test and hydrogen content measurement. Slow strain rate testing (SSRT) under cathodic conditions as well as mechanical performance degradation testing after long term immersion were e

Stefano Rossi, Michele Fedel - The metallic foams, in particular based on aluminum and aluminum alloys, produced by foaming in a sponge shape, show very interesting engineering properties in particular connected with the very low density. Mechanical cutting or working could open the closed cell increasing the reactive area and producing a very complex geometry. Then, In some aggressive environments, the corrosion behavior of this material could be critical. A suitable method to increase the corrosion resistance is desirable. The use of organic or inorganic coatings could be a possible solution. The cataphoretic deposition is an interesting method to obtain a very protective and homogenous paint layer also with complex geometry. The deposition of a vitreous layer could improve the corrosion behavior maintaining the fire resistance properties. Considering the particular geometry of foam it is not easy to obtain a very performed coatings. It is necessary to individuate the optimize

Mohammed1* Richard Barker2 and Anne Neville3 1-3 Institute of Functional Surfaces, School of Mechanical Engineering, University of Leeds * mnsam@leeds.ac.uk abstract Oil and gas applications largely involve use of low carbon steel due to its low cost, available technology, ability to form protective film amongst others. Protective films could however become compromised due to a number of reasons such as mechanical, chemical or a combination of factors [1], therefore leading to localised corrosion. This takes toll on operations, economy as well as Health and Safety concerns. Pitting corrosion ranks among the highest level of corrosion defects while pitting in sweet (CO2 environment) remains the most dangerous form of localised corrosion [2, 3]. Carbon steel pitting as well occurs in sweet environment where protective film is not formed. Pitting is hard to predict [2] and could

Alberto Sagues, Jacob Bumgardner - Forecasting corrosion of steel in concrete in aggressive chloride-rich service is usually made with statistical models that consider variability in key parameters that may include not only reinforcement clear cover, surface chloride concentration, chloride ion diffusivity and  critical chloride concentration but also  the effect of aging on chloride transport, moisture exposure, mechanical resistance to corrosion induced cracking and a host of other characteristics. A classic compromise emerges then involving usefulness of outcome, model complexity, and confidence in the quality of input parameters. Using trial calculations and conisderation of the physical impact of the various phenomena involved, this work explores the relative benefits in outcome of incorporating additional variables in a forecasting model, toward establishing  rational  criteria on how to limit the number of variables to be used in practical service life estimates.

Christine BLANC, Marie-Laetitia de BONFILS-LAHOVARY, Cedric Charvillat, Lydia LAFFONT, Manon Lafouresse - Hydrogen embrittlement is suspected to play a major role in the corrosion of aluminium alloys. This work aims at determining the influence of hydrogen on the corrosion damage of AA2024 aluminium alloy, a commonly used alloy in aeronautics. A powerful way to study hydrogen embrittlement at a local scale is by combining atomic force microscope and Kelvin probe force microscope (AFM-KFM). This technique by measuring the surface potential at the nanometer scale allows the detection and localization of hydrogen in the alloy. Firstly AFM-KFM measurements were taken on model materials containing a controlled quantity of hydrogen. Hydrogen was inserted into AA2024 alloy via cathodic charging in H2SO4 through one of the short transverse (ST)/ long transverse (LT) sides. AFM-KFM images taken on the side perpendicular (ST/rolling direction (RD)) revealed a surface potential gradient o

Antoni Prieto, Raquel Morales Roset, Jose Luna - Challenging the Performance Myth of Inorganic Zinc Rich vs Organic Zinc Rich Primers Abstract Zinc rich primer coatings, both organic and inorganic, are extensively used in highly corrosive environments and they are part of a high performance coating system in the Protective Coatings Industry. During the 60’s and the 70’s, zinc rich epoxy primers dominated the market. Later, zinc ethyl silicate primers took over this role, but nowadays it appears as if zinc epoxy primers have made a comeback. Some of the advantages of zinc epoxies compared to zinc silicates are the less demanding curing conditions (epoxies will cure at low humidity), they are easier to overcoat and they are less demanding to substrate preparation prior to application. Zinc epoxies are typically formulated with high loads of zinc dust also zinc epoxies are mechanically stronger meaning that in the real life over thickness is less problematic for new generation o

Gregg Robinson, Trevor dale - Abstract Treating steam condensate systems with neutralizing and filming amines has been commonplace in industry for several decades.  Refinery steam and condensate systems are often considered “tough to treat” due to their complex configuration and uses of the steam – direct injection in furnaces and distillation towers, flash-steam reboilers, high alkalinity make-up water sources, multiple opportunities to introduce hydrocarbon contaminants, and several other factors – requiring extra attention to maintain good system protection while minimizing impact on the process.  Specifically, improper selection and application of steam neutralizing amines can contribute to salt-induced fouling and corrosion in crude overhead systems.  In response, technology development in the areas of amine performance modelling, neutralizing amine selection, and the use of volatile filming corrosion inhibitors facilitates steam system protection and avoids process syste

Jing Ning, Yougui Zheng, Bruce Brown, Srdjan Nesic - Localized corrosion in sour fields is a challenge persisting in the oil and gas industry since it has frequently been seen as a cause for catastrophic failures of upstream pipelines. However, compared to H2S general corrosion, there is minimal understanding of H2S localized corrosion. Mechanisms of H2S localized corrosion are unclear and the causes of H2S localized corrosion are uncertain. Therefore, seeking an experimental condition in the laboratory that can replicate localized corrosion in a sour environment is critical to understand mechanisms of localized corrosion. In the previous study, a strong correlation between the formation of greigite and/or pyrite and onset of localized corrosion was observed. Consequently, the formation of greigite and/or pyrite was hypothesized to play an important role in the initiation of localized corrosion. Novel experiments involving deposition of pyrite on the steel surface were then desig
