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。

埋弧焊直缝钢管采用的焊接工艺为埋弧焊技术,采用填充物焊接,颗粒保护焊剂埋弧。生产的口径可以达到1500mm,LSAW是埋弧焊直缝钢管的英文简称,埋弧焊直缝钢管的生产工艺有JCOE成型技术、卷制成型埋弧焊技术。当口径较大时可能用两块钢板进行卷制,这样会形成双焊缝的现象。可以执行的标准GB/T3091-2008低压流体钢管生产标准,GB/T9711.1-2 -1997石油天然气钢管生产使用标准,还可以执行美国API 5L 管线钢管执行标准。生产材质:Q195A-Q345E;245R;Q345QA-D;L245-L485;X42-X70。承压参数主要有2ST/T ,S为屈服强度,T为壁厚。埋弧焊已经发展成为,有双丝埋弧焊,还有多丝埋弧焊,效率更进一步提高。
