hi there is a mistake.i asked :according to usage limitadion of nace mr 175 in refinery equepment, is there any code or standard about scc in refinery equepment?

Actually MR 0175 is applicable for upstream Oil Field Equipments and infrastructures. To facilitate material selection for downstream refinary and petrochemical plant NACE Task Group has evolved a new system MR 0130 . You can refer that. This MR 0130 has typical differences w.r.t. MR 0175. Hope this helps. regards DM

TAM Enough input has been given for the original question on sour pipe material standard. Adding further, try to look at NACE web site or u can purchase the same from NACE Houston.
