Experiment Study on Safety Evaluation of L245A-Pipe Steel in Wet H<sub>2</sub>S Environment

Abstract

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.
