As Pipeline in Wet H2S environment must consider its anti-hydrogen-induced cracking (HIC) and sulfide stress corrosion cracking (SSCC) performance, in this paper, to ensure L245A-pipe mechanical properties qualified under the premise, according to NACE TM 0284-2003 and NACE TM 0177-2005 standard conducted a test evaluation in Wet H2S in the context of anti-hydrogen-induced cracking performance (HIC) and sulfide stress corrosion cracking resistance (SSCC) and came L245A-pipe in standard Wet H2S environment didn’t produce hydrogen-induced cracking, occurred sulfide stress corrosion cracking, the design conditions and working conditions are no stress corrosion cracking conclusions. And make recommendations on the safe operation in Wet H2S.

Sulfide Stress Corrosion Cracking

High-strength oil country tubular goods (OCTG) like C110, according to standard API 5CT (yield strength at least 758 MPa), are subject to requirements in terms of mechanical and corrosion properties. In this work, we studied the microstructure of seamless casing tubes made of class C110 high-strength steel with a 194.5 mm diameter and 19.7 mm wall thickness, and its influence on sulfide stress corrosion cracking (SSC). Casing tubes were obtained from continuous billets by screw piercing with preliminary quenching and tempering. It was shown that cracking during the tests always begins from the inner surface of the tube. Rough segregation bands were found on the inner tube surface, which occupies about a third of the thickness of the wall. To increase the resistance of 0.3C-Cr-Mn-Mo + 0.15(V + Nb + Ti) steel to SSC, primary recommendations for adjusting the chemical composition, production technology and heat treatment were developed.
