Robust integrity management plans are critical for ensuring the lifespan and preventing failures of manmade infrastructure, including the metal (carbon steel) infrastructure that dominates the oil and gas industry. In this sector and others, many types of corrosion can occur on metal infrastructure, including corrosion that involves the participation of microorganisms, commonly referred to as microbiologically influenced corrosion, or MIC. MIC can be difficult to diagnose as the cause of a given infrastructure failure because it is not a stand-alone mechanism – the physical and chemical properties of a system can influence the types of microorganisms that are present and active, while the metabolisms of these microorganisms can influence the surrounding chemistry and physical properties of a system.

Impact of Specimen Geometry on Cathodic Disbondment Testing for Protective Coatings

Product Number: 51319-13367-SG

Author: Jessica Torrey

Publication Date: 2019

$20.00

At NACE Corrosion 2018 researchers provided a side-by-side comparison of two cathodic disbondment test methodologies: NACE TM0115 and ASTM G8. During this testing the cathodic disbondment results varied based on specimen geometry contrary to previous findings which claim independence. Researchers designed a subsequent experiment to further elucidate the results of the prior study. The approach utilized NACE TM0115 test standard and a matrix of two coating systems and five sample geometries. One test set-up evaluated the following samples in immersion: 2-inch 3-inch and 4-inch diameter pipe as well as 4-inch by 6-inch flat panels. A second test set-up utilized the attached cell method. The paper presents the results of this experiment and provides recommendations to create a more robust test method for correlating cathodic disbondment testing to the selection of coatings systems to be used in conjunction with cathodic protection.

Impact of Test Method on Sulfide Stress Cracking Fracture Toughness

When dealing with the risk of Sulfide Stress Cracking (SSC) of Oil Country Tubular Goods (OCTG) as casings and tubings, two main approaches are: either the determination of the threshold stress on a smooth tensile specimen (NACE TM0177 Method A) or the fracture toughness KISSC on a Double Cantilever Beam (DCB) specimen (NACE TM0177 Method D).
Relevance of KISSC for predicting the behavior of real pipes in service has been assessed in the frame of API PRAC project Phase II.1 Hollow tensile specimens sampled in the wall of sour service seamless pipes were exposed to sour environments either on Inner Diameter (ID), Outer Diameter (OD) or both and subjected to a tensile loading (see also references

Corrosion in crude distillation unit overhead lines is primarily caused by hydrochloric acid at the dew point. Various other contaminants including air, organic acids, H2S, NH3, tramp amines, HCN, mercaptans, phenols, etc. also play a role in overhead corrosion. Mitigation strategies include process solutions such as wash water systems and temperature control, and chemical solutions including amine-based neutralizers and film-forming inhibitors. Despite implementing these strategies, corrosion is invariably observed in the overhead system. Conventional “non-volatile” filmers rely on free liquid to cover the metallurgy. However, the complex nature of overhead geometry and fluid flow make complete metal coverage challenging. This necessitates a different strategy to achieve protection. Here, we present a first of its kind Vapor Phase Corrosion Inhibitor (VPCI) for protecting overhead systems. Several VPCI candidates were studied in the lab for performance, volatility, and risks (emulsification, pentane solubility, amine salt fouling, thermal stability). Promising VPCI was field trialed in several refineries.

Impact of Very Low Concentration of Soluble Salts on Coatings Performance

Product Number: 51319-13218-SG

For offshore platform maintenance coating operation dry grit blasting is a common practice to clean the steel surface. The offshore platform steels are in a various degree of corrosion. It is well known that dry grit blasting alone cannot remove salts completely and some residual salts remain on blasted steel surface. In offshore corrosive environment grit blasted steel surfaces will quickly become rusted within a couple of hours. It is hard to keep the desired near white metal finish for 2-4 hours until the coating spray application. There are several commercial cleaning chemicals to remove residual salts and to extend the surface cleanliness time.This paper covers the testing and comparison of some of these chemicals and impact on coating performance. The evaluation was in 2 parts:1. Compare various salt removal solutions.2. Evaluate the compatibility and impact of the best salt removal solution on coating performance.In the first part of the testing tests showed that one of the products did out-perform the other chemicals to remove residual salts and maintain a desired surface pH.The second part of testing was done since there was a concern about the compatibility of the salt removal product and coatings. Thus the best salt removal product was then further tested with various coating types applied. Three (3) atmosphere coatings and three (3) tank linings (immersion grade) were selected for the compatibility study.The conclusion was that one salt removal solution did out-perform other systems and the salt removal solution was compatibility with the various coatings and improved performance of the coating.

Piping and pipeline are considered to be 60-70% of the oil and gas industry equipment. One of the most crucial factors to complete high quality projects within planned schedules is to focus on the quality of welding activities. Furthermore, the non-skilled welder is considered as a main parameter to produce welds with imperfections beyond the acceptable limits. Welders should have the required welding skills to perform the welding activities and produce sound welds, resulting in low weld rejection. On the other hand, poor welder’s performance produces low quality welds which affect the integrity of the welds and contribute to project delay and increase costs. This paper addresses methods to qualify welders and monitor their performance throughout the project lifecycle. The paper will study ISO 9606 approval testing of welders, American Welding Society (AWS) and American Society of Mechanical Engineers (ASME) Sec IX minimum requirements to qualify and certify welders. It will also illustrate the main variables that may contribute to high welding rejection rate, that are directly associated with the welders’ qualification and performance. Moreover, it will study the method of qualifying welders for different levels to properly assign welders based on load and criticality to avoid high welding rejection rate. The study shows that welders’ skill is the main parameter to produce high quality welds. Focusing on the causes of common welding defects, then educate and train the welders on the main factors causing these welding defects, will leave an influence to prevent defect recurrence
