Hey everybody, my question is about SSC (Sulfide Stress Cracking). I would like to know what is the procedure of big oil companies for preventing SSC?

11 November 2017 1 10K Report

Is it enough to know that hardness of weld is below 22 HRC (Is hardness measurement enough)? or PWHT or Preheat is needed and when? what would be the best procedure to improve the SSC resistance?

Thanks.

Hello..been a piping materials engineer in the EPC industry for 12 years..during engineering phase, NACE docs like MR0175 and MR0103 are the go-to documents in preventing SSC.."sour" requirements are strictly delineated during design..as for plant maintenance/rehab, i believe they reference those documents too..
