直缝钢管简介直缝钢管是焊缝与钢管纵向平行的钢管。通常分为公制电焊钢管、电焊薄壁管、变压器冷却油管等等。直缝焊管生产工艺简单,生产效率高,成本低,发展较快。螺旋焊管的强度一般比直缝焊管高,能用较窄的坯料生…

直缝钢管是焊缝与钢管纵向平行的钢管。通常分为公制电焊钢管、电焊薄壁管、变压器冷却油管等等。直缝焊管生产工艺简单,生产效率高,成本低,发展较快。螺旋焊管的强度一般比直缝焊管高,能用较窄的坯料生产管径较大的焊管,还可以用同样宽度的坯料生产管径不同的焊管。但是与相同长度的直缝管相比,焊缝长度增加30~100%,而且生产速度较低。

直缝钢管的高频焊接正是利用交流电的趋肤效应和邻近效应,钢材(带钢)经滚压成型后,形成一个截面断开的圆形管坯,在管坯内靠近感应线圈中心附近旋转一个或一组阻抗器(磁棒),阻抗器与管坯开口处形成一个电磁感应回路,在趋肤效应和邻近效应的作用下,管坯开口处边缘产生强大而集中的热效应,使焊缝边缘迅速加热到焊接所需温度经压辊挤压后,熔融状态的金属实现晶间接合,冷却后形成一条牢固的对接焊缝。
