Abstract Cracking of Ω loop of high pressure hydrogenation heat exchanger was analyzed by means of morphology and microstructure analysis, chemical composition analysis, SEM micro-morphology analysis and EDS analysis. The results showed that the cracking of the sample was to be hydrogen sulfide stress corrosion cracking. The high working stress and a few of hydrogen sulfide in shell side induced the cracking of the Ω loop jointly.

Key words: heat exchanger &Omega loop hydrogen sulfide stress corrosion cracking
