Abstract：The sulfur stress corrosion crack (SSCC) test of weld seam of X65 UOE pipe were studied by using four point bending (FPB) specimen according to the NACE 0177 standards. The strain gauge was used for identifying target strain and loading target stress. The results show that it is efficient to build the relationship among strain, load and stress for four point bending (FPB) specimen by utilizing the method of strain gauge. The target load strain against target load stress can be obtained by the relationship. The loading of 90% actual yield stress were accomplished for the three test specimens by using the method of strain gauge, no crack was observed on the specimen surface after immersion in H2S saturate solution of 720 hours. The test materials show high resistance to the sulfur stress corrosion crack.
