摘要:
为了研究全自动焊在役管线的真实承压能力,通过水压爆破试验对全自动焊含缺陷环焊缝在役管段的承载能力进行研究。研究结果表明,全自动焊焊接工艺下环焊缝缺陷主要是未熔合缺陷,且3种含未熔合缺陷管段起爆点、爆破压力、撕裂方向大致相同;含3种未熔合缺陷环焊缝管段的真实爆破压力均大于爆破压力的理论计算值,远远满足现场运行所需要的承载能力;含缺陷环焊缝的存在并没有对在役管段的整体承载能力造成影响;管段的承载能力主要取决于母材自身的材料性能。
Abstract:
In order to study the real pressure bearing capacity of the in-service pipeline by the full automatic welding technology, the bearing capacity of the automaticwelding of the in-service pipe sections with detective girth welds is studied through the hydraulic blasting test. The results show that the main defects of the girth weld in full automatic welding process are imcomplete fusion, and the initiation point, bursting pressure and tearing direction of three kinds of the pipe sections with imcomplete fusion defects are almost the same. The real bursting pressure of the girth weld pipe section with three kinds of incomplete fusion defects is greater than the theoretical calculation value of the bursting pressure, which is far enough to meet the bearing capacity required by the field operation. The existence of the defective girth weld does not affect the overall bearing capacity of the in-service pipe section. The bearing capacity of the pipe section mainly depends on the material properties of the base metal.
