| 详细介绍：
螺旋钢管是以带钢卷板为原材料,经常温挤压成型,以自动双丝双面埋弧焊工艺焊接而成的螺旋缝钢管.
（1）原材料即带钢卷，焊丝，焊剂。在投入前都要经过严格的理化检验。
（2）带钢头尾对接，采用单丝或双丝埋弧焊接，在卷成钢管后采用自动埋弧焊补焊。
（3）成型前，带钢经过矫平、剪边、刨边，表面清理输送和予弯边处理。（4）采用电接点压力表控制输送机两边压下油缸的压力，确保了带钢的平稳输送。
（5）采用外控或内控辊式成型。
（6）采用焊缝间隙控制装置来保证焊缝间隙满足焊接要求，管径，错边量和焊缝间隙都得到严格的控制。
（7）内焊和外焊均采用美国林肯电焊机进行单丝或双丝埋弧焊接，从而获得稳定的焊接规范。
