摘要
通过对影响螺旋焊管拉伸试样断裂位置因素的分析,指出拉伸试样断裂点应位于试样标距中间,并介绍了试验中避免断裂点偏移标距中间的方法。
Through the analysis of factors which will effect breaking location of tensile testing of helical welding pipe,this article indicates breakpoint of tensile test shall locate in middle of sample gauge length,and also introduce the method to avoid breakpoint deviating the middle of gauge length.
