摘要: 在长输油气管道站场建设中，阀门、仪表和法兰的安装需要在主管道上开孔。高频直缝电阻焊管母材焊缝肉眼难以辨认，部分凸台安装位置距离电阻焊管焊缝很近甚至重合，因此凸台安装焊接对主管本身的影响程度需要深入研究分析。本文利用小孔法测量了高频直缝电阻焊管残余应力分布规律、凸台不同位置焊接对高频直缝电阻焊管原始残余应力的影响程度，发现电阻焊管开孔焊接凸台后，应力急剧上升，且凸台焊接对焊管纵焊缝上原始残余应力的影响远大于对管体的影响。
Abstract: During the station construction of gas and oil Pipelines, valves, instrument and flanges installation requires tapping in the main pipeline. It is hardly to identify visually the base pipe straight seam location of high frequency electric resistance welding. Some boss mounting positions are very close to electric welding pipe seam. Hence, it is very necessary to study the deep research and analysis for the boss installation influence on the base pipeline. The paper analyses the residual stress dis-tribution on the high-frequency straight seam resistance welding pipeline by hole-drilling, and original residual stress impact about the different boss welding positions on high-frequency straight seam resistance welding pipe. There is a sharp rise in stress and the longitudinal weld re-sidual stress impact after the boss installation on the electric resistance weld pipes is much larger than the mother pipeline.
