| Abstract: | s: The pressure gauge nozzle of quench hydrogen pipeline of the hydroprocessing unit in Tianjin Petrochemical Company's refinery ruptured in June 20, 2001. The chemical, metallographic and SEM testings confirmed that the rupture was the result of stress corrosion cracking in the wet hydrogen sulfide environment because of inappropriate material selection. The selection of austenitic stainless steel and proper protection in unit shut-down could prevent the incident. |
