The requirements for seamless pipes on NACE MR0175 are: the S content must not exceed 0.010%. However, the requirements for Steel Plates and welded pipes are particularly strict: S must not exceed 0.003%. Although strict requirements are imposed on the steel plate, it can pass the HIC test, but the welding seam has to pass the test, which is still a very difficult problem. Not only must we choose the good welding material, but also the skilled welding process.
