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。

直缝钢管英文(Straightsteel pipe),一般焊管:一般焊管用来输送低压流体。用Q195、Q215A、Q235A钢、Q235B普碳制造 。也可采用易于焊接0317标准型号6012及钢母755软钢共同制造。钢管要进行水压、弯曲、压扁等实验,对表面质量有一定要求,通常交货长度为4-10m,常要求定尺(或倍尺)交货。焊管的规格用公称口径表示(毫米或英寸)公称口径与实际不同,焊管按规定壁厚有普通钢管和加厚钢管两种,钢管按管端形式又分带螺纹和不带螺纹两种。
