- 摘要:
- 为提高大口径管道的焊接速度和质量,研制了长输管道现场焊接所需的带铜衬垫气动内对口器,对四类衬垫材料分别进行了抗烧损试验和使用寿命焊接试验,根据试验结果,并综合现场焊接工艺要求和施工成本等因素,确定了铬锆铜和紫铜表面喷涂镍铬陶瓷两种材料较适宜用作焊接衬垫材料。
In order to boost welding speed and quality of large diameter pipelines, a pneumatic pipe inter- nal line-up clamp with copper pad has been developed for field welding of long-distance pipelines. Burnback resistance test and service life welding test for four kinds of pad materials were carried out. According to the test results and considering the field welding process requirements and construction cost, two materials were chosen as the proper welding pad material, that were CrZrCu and copper with surface coating of nickel chrome ceramic.2009,2(2): 10-12 收稿日期：2008-11-11分类号：TE973.3作者简介：吴江桥(1979-),男,浙江义乌人,2007年毕业于西南石油大学,工学硕士,主要从事管道施工装备及焊接工艺方面的研究工作.参考文献：
