Sulfide stress cracking (SSC) occurs in steel exposed to sour environments. Ni promotes the formation of a crack-like corrosion morphology (so-called stress groove or fissure), which accelerates the SSC; however, the mechanisms underlying fissure formation and growth are not fully understood. In this study, the effects of Ni on SSC and fissures were investigated. Constant-load tests were conducted at various potentials using TS 800 MPa grade steel with and without 1 % Ni addition. The fissures were formed near the corrosion potential on adding Ni. Anodic or cathodic polarization promoted SSC, suggesting that SSC was affected by both active path corrosion (APC) and hydrogen embrittlement (HE) mechanisms. In addition, the fissure shapes and crystal orientations of the microstructure were analyzed to classify the fissures as dissolution (corrosion) or mechanical cracking. Further, characteristic grooves promoted by Ni were confirmed to be APC.

Digital Twin as a Tool for Extending In-Line Inspection Intervals

Aging pipeline assets are a concern for many pipeline operators. As pipelines age, external corrosion control becomes more challenging and often results in more aggressive monitoring and maintenance activities such as more frequent in-line inspections (ILI) and direct examinations. A pipeline case study is discussed demonstrating how a digital twin based on mechanistic modeling was utilized as a proof of concept for identifying possible cathodic protection remedial actions to decrease external corrosion growth rates (CGR) with the goal of extending the ILI inspection interval from 3 to 5 years. Various remediations such as adjusting or adding cathodic protection and resolving interference are modeled and compared with the existing corrosion control configuration. An economic analysis is included to determine if theoretical remediations can reduce monitoring and maintenance costs while maintaining asset integrity.

Low Temperature Effect on Sulfide Stress Crack Initiation in Low Alloy Steels

Product Number: 51319-12856-SG

Publication Date: 2019

Exposure temperature has a known effect on sulfide stress cracking (SSC) where elevated temperatures permit the use of oil country tubular goods (OCTG) in sour conditions that would not be survivable at lower temperatures. In order to assess SSC susceptibility NACE MR0175 / ISO15156-2 and API 5CT advise or require the use of room temperature NACE exposure tests in H2S-containing brines and consequently the bulk of qualification data on OCTG has been obtained at these conditions. Previous publications have demonstrated the effect of lower temperatures e.g. 40°F testing on KISSC values of low alloy steel using double cantilever beam (DCB) tests showing a reduction on sour toughness when the temperature is lowered from 75°F to 40°F. This KISSC data provides a clear indication of SSC severity at 40°F on crack propagation; however very little data is available pertinent to crack initiation at temperatures lower than 75°F.In this work several crack initiation tests were performed in mild sour conditions and demonstrated that at low temperature crack initiation susceptibility is increased. Details of the results are discussed within the context of traditional SSC qualification tests and materials selection standards along with the theoretical understanding of SSC fundamentals. Cracking tendency and time-to-failure are reviewed within the context of environmental and material parameters that are altered by the exposure temperature including hydrogen diffusion corrosion rate dissolved H2S concentration and the behavior of hydrogen traps.

Substitution of Carbon Steels for Material SA-533 Type E for Lightweight Equipment

For many years MnMoNi alloy steels (ASME SA-533 type B or type C class 2) have been used in the substitution of carbon steels for the manufacture of equipment when weight reduction is critical. Nevertheless the use of these low alloy steels for equipment in sour service remains limited as their weldability is considered challenging. This paper aims at introducing an optimized chemical analysis based on material ASME SA-533 type E class 2. Test results on base metal and welded coupons will be described especially with respect to NACE MR0175/ISO 15156-2. Corrosion tests in amine solution done on SA-533 type E class 2 and carbon steel ASME SA-516 Gradde 65 are also be provided that show the low alloy steel behaves at least as well as the reference carbon steel.

Corrosion and corrosion inhibitor qualification testing has been the subject of many publications over the years, with various guidelines and in-house protocols produced. This has led to a rather large set of test approaches for the qualification of corrosion inhibitors (CIs) for application in oil and gas production facilities.


For challenging conditions, including severe downhole conditions, final testing is often performed via specialized autoclaves or high-pressure flow loops to allow tests to be conducted under conditions as close to those pertaining in the field: T, P, pCO2 and pH2S (or more realistically, fugacity of CO2 and H2S), and as close as can be achieved to the field hydrodynamics.

Testing of Large-Diameter Pipe Material for Resistance to SOHIC in the New Twist and Bend Test

Stress Oriented Hydrogen Induced Cracking (SOHIC) is recognized as an individual cracking mechanism in NACE MR0175/ISO 15156-2. SOHIC occurrence is rare and the mechanism not fully understood but thought to be restricted to carbon and low-alloy steels with low strength and low hardness. Several SOHIC resistance test methods have been reported but none of the test methods is currently standardized. The newly developed “twist and bend” test is currently under standardization in NACE TG 536.Within this work SOHIC resistance tests using the “twist and bend” test method were performed on SAWL large-diameter pipes of grades X52 and X65. All relevant sampling positions (base material heat-affected zone longitudinal weld) were investigated and the results were compared to standard four-point bend SSC tests without additional twist. A new test geometry using reduced specimen dimensions that allows testing of smaller specimens for weld regions has also been developed.The SOHIC performance is discussed based on grade microstructure and hardness of the investigated pipe materials. The investigated SAWL large-diameter pipes revealed excellent SOHIC resistance.
