焊接鋼管采用的坯料是鋼板或帶鋼，因其焊接工藝不同而分為爐焊管、電焊(電阻焊)管和自動電弧焊管。因其（qí）焊（hàn）接形式的不同分為（wéi）直縫焊管和螺旋焊管兩種。因其端部形狀（zhuàng）又分為圓形焊（hàn）管和異型(方、扁等)焊管。焊管因其材質和用（yòng）途不同而（ér）分為如下若幹品種：
The billet used in welded steel pipe is steel plate or strip. It is divided into furnace welded pipe, electric welded pipe and automatic arc welded pipe because of different welding technology. Because of its different welding forms, it can be divided into straight welded pipe and spiral welded pipe. Because of its end shape, it can be divided into circular welded pipe and special-shaped (square, flat, etc.) welded pipe. Welded pipes can be divided into the following categories because of their different materials and uses: GB/T3091-1993(低壓流體輸送用（yòng）鍍（dù）鋅焊接鋼管)。主要用於輸（shū）送水、煤氣、空氣、油和取暖熱水或蒸汽等一般較低壓力流體和其他用途管。其代表材質Q235A級鋼。
