| 摘 要： | 通过C型环试样应力腐蚀敏感性试验,评定了不同焊条焊接20号钢管在硫化氢介质中的应力腐蚀开裂的敏感性以及焊后热处理对SSCC的影响。实验结果表明：J422焊条焊接的焊接接头比J507焊条焊接的抗SSCC性能好,焊后热处理可以降低SSCC敏感性。

| Abstract: | The SSCC sensitivity of 20# steel pipes welded with different electrodes in H_2S media and the impact of PWHT on SSCC were evaluated through C ring sample SSCC sensitivity tests.The tests exhibit that the weld connections by J422 electrode are more resistant to SSCC than those by J507 electrodes.The PWHT can reduce the SSCC sensitivity. |
