1、焊管尺寸规格表焊接钢管采用的坯料是钢板或带钢，因其焊接工艺不同而分为炉焊管、电焊（电阻焊）管和自动电弧焊管。因其焊接形式的不同分为直缝焊管和螺旋焊管两种。因其端部形状又分为圆形焊管和异型（方、扁等）焊管。焊管因其材质和用途不同而分为如下若干品种：GB/T3091-2001（低压流体输送用镀锌焊接钢管）。GB/T14291-2006（矿用流体输送焊接钢管）。GB/T14980-1994（低压流体输送用大直径电焊钢管）。GB/T12770-2002（机械结构用不锈钢焊接钢管）。GB/T12771-1991（流体输送用不锈钢焊接钢管）。装饰用焊接不锈钢管（GB/T 18705-2002），建筑装饰用
