| 摘 要： | 通过改进的WOL预裂纹试样应力腐蚀试验，得到了在500，1000ppm的硫化氢水溶液中，X60螺旋焊管的应力腐蚀裂纹扩展速率da／dt，结果表明，随硫化氢水溶液浓度的增加，X60螺旋缝埋弧焊管应力腐蚀裂纹扩展速率增加，焊管抗应力腐蚀的寿命越短。

| Abstract: | Through stress corrosion tests for reforming pre - cracked wedge - open loading specimens , the da/dt of X60 spiral welded pipe were gotten in 500 ppm and 1000 ppm H2S solution .The results shows that da/dt of welded material is increased , and life of stress corrosion cracking of X60 spiral welded pipe in wet H2S environment is shorter with increasing concentration of H2S in solution. |
