| Abstract: | As a result of refining imported high sulpher crude oil in recent years, more and more interior surface stress corrosion cracks were found in oil refining spheres. The reason and the main influence factors to the stress corrosion cracking of spheres were analysed. Based on the research on the safety of pressure vessels and LPG spherical tanks, the mechanisms of stress corrosion cracking in wet Hz S environment are analyzed. The pre-fatigue crack M-WOL specimen stress corrosion cracking tests irr three H2S concentrations are performed under different welding conditions. A safety performance analysis of equipment has been made, and preventve countermeasures have been proposed. |

| Keywords: | wet sulfide hydrogen environment stress corrosion cracking high strength steel safety performance analysis |
