| Abstract: | Some 0Cr18Ni9 stainless steel pipe fittings corrosion cracked before and during trial run of PVC project.Through referring the material of cracked fittings and construction documents and performing metallographic examination and chemical element analysis,the cracking causes were found.The causes included ① the purchased 0Cr18Ni9 stainless steel pipe fittings didn’t comply with the design requirements;② water for pressure test contained exessive chloride ions and didn’t meet the requirements and wasn’t discharged in time;③ effective supervision and management were poor. |
