Study of HIC and SSCC Experiment on L245A-steel Pipe in Wet H2S Environment
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 designed eight tests in accordance with L245A-steel pipe and welded joints in the different medium concentration and operating conditions, by reducing medium concentration and operation pressure in Wet H2S in the context of anti-hydrogen-induced cracking performance (HIC) and sulfide stress corrosion cracking resistance (SSCC). Through the four-Test came L245A-pipe in standard Wet H2S environment didnt 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.
