...Abstract TMCP (Thermo-mechanical controlled process) large diameter linepipes have been used since a long time for high-strength and severe sour application, but recently Sulfide Stress Cracking (SSC) caused by local hard zones has become a concern. In this paper, material design concept...

...INTRODUCTION The resistance of low-alloy steel oil country tubular goods (OCTG) to sulfide stress cracking (SSC) is an important issue regarding material selection. The NACE TM0177-2016 ¹ standard describes several test methods to be used to assess the susceptibility of steels during...

...Sulfide stress Cracking Grooving Proof-Ring 4-point bend Considering the volume of solution used for the circulation the “volume of solution to specimen surface ratio” (V/S) during the test was about 250 and 750 mL/cm² for proof-ring and dead-weight respectively. The test procedure...

... was used for all testing reviewed herein. Abstract There exists a commonly-held belief that as-delivered oil country tubular goods (OCTG) possess superior resistance to sulfide stress cracking (SSC) than standardized testing for SSC may identify. This belief relies on the nature of the mill scale present...

... to define the SSC (Sulfide Stress Cracking) limits of TMCP pipes, to do a literature survey on Non-Destructive Techniques (NDT) able to detect surface hardness anomalies, and finally to reproduce hard layers through a "lab scale TMCP rolling” and point out the potential root cause of surface hardening...

... Abstract Oil country tubular goods (OCTG) are routinely evaluated for sulfide stress cracking (SSC) resistance. Historically, most qualifications relied on full sour, i.e. 1 bar H₂S, to assure sour grades of OCTG for service in the field. Over the past two decades, it has become more routine...

... toughness and hardenability and does not promote the formation of carbides that could retain hydrogen into the steels. In this work, a set of five steels with different nickel content was specially fabricated to study the effect of that element on the sulfide stress cracking (SSC) resistance. Quenching...

... conventional approaches to evaluate sulfide stress cracking susceptibility. In these environments, pitting corrosion and cracking driven by hydrogen embrittlement can simultaneously damage the surface of the steel test coupon. Subsequent coupon analysis and a pass/fail determination can be problematic...

...Abstract Steel pipelines are sometimes subjected to demanding sour environments resulting from the presence of high H₂S contents. Pipeline materials, therefore, must be resilient against sulfide stress cracking (SSC) which is caused by H₂S. Beginning in the 1980s, thermo...

...INTRODUCTION Abstract Seamless X60QOS and X65QOS linepipes are widely used for Sour Service offshore and onshore applications. Sour Service refers to the risk of hydrogen related cracking, such as by Sulfide Stress Cracking (SSC). The International standard NACE MR0175 / ISO 15156 provides...
