...Abstract In the oil and gas industry, pipelines are exposed to wet H₂S environments (sour environments) that cause sulfide stress cracking (SSC) in low-alloy carbon steels in some cases. Recently, a judgment flowchart was proposed to determine the SSC susceptibility based...

... and qualification in the new region. H₂S sour sulfide stress cracking linepipe OCTG DCB INTRODUCTION Selection of the appropriately resistant materials for H₂S-containing conditions in oil and gas production remains a critical barrier to catastrophic incidents that might otherwise claim...

...Linepipe steels need to have a sufficient resistance to sulfide stress cracking (SSC) in a wet sour environment containing H₂S gas. In 2013, actual sour gas pipeline failure occurred due to SSC under high H₂S partial pressure condition over 1bar. One of the possible root...

... resist both sulfide stress crack (SSC) initiation and potential propagation from defects in service. A laboratory study was conducted to assess the tendency of crack propagation from two defined types of defects, electro-discharge machined (EDM) notches and fatigue cracks, simulating potential...

... the mechanisms of the formation of fissure and its growth. Following the previous paper that deals with the constant load test, this paper introduces the results from the four point bend test. Abstract Four point bend sulfide stress cracking (SSC) tests were carried out under various conditions...

...Abstract 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...

...Abstract A Sulfide Stress Cracking (SSC) qualification program was conducted for carbon steel components (piping, flanges, and fittings with SMYS 450 MPa) and its welds for an offshore facility piping system that may carry off-spec gas in the event of a temporary malfunction of the dehydration...

..., such as constant load tests, three-and four-point bending tests, and slow strain rate tests. These features can act as crack initiation sites in sulfide stress cracking (SSC) tests for material selection and qualification, often conducted at the open circuit potential. How different material, environment...

...Abstract Hydrogen embrittlement, such as sulfide stress cracking, occurs in low-alloy carbon steels under sour environments. The amount of absorbed hydrogen increases with increasing plastic strain introduced into the steel materials. The susceptibility to hydrogen embrittlement increases...

... issue has been often discussed regarding sulfide stress cracking (SSC) in severe sour environment containing H₂S gas. One of the possible root cause of SSC was assumed by formation of hard-zones in the steel pipe inner surface. Advanced-OLAC-based cooling rate control for surface and mid...

There are only limited results about the fatigue behavior of high-strength steel welded joints and, especially, in sour environments. Therefore, the performance of X80 mechanized girth weld was assessed in air and in mild sour...
