螺旋缝埋弧焊钢管产品规格为：公称外径∮219～∮2200mm,公称壁厚6～20mm,钢管长度8～12m,按API Spec 5L和GB/T9711.1标准组织生产,可采用API Spec 5L的A、B、X42～X80GB/9711的L175～L555钢种或与之等效的其它标准钢种生产。 亦可按SY/T5037-92及SY/T504092标准供应钢管，采用GB700和GB1591中Q235、Q255级或其它钢种焊制。还按用户指定的其它技术或双方协议条件组织生产。

高频直缝电阻焊钢管 （High-frequency Electrical Resistance Welded Steel Pipe, 简称ERW ） 是热轧卷板经过成型机成型后，利用高频电流的集肤效应和邻近效应，使管坯边缘加热熔化，在挤压辊的作用下进行压力焊接来实现生产。世界范围内已有近20个国家在生主ERW石油专用管、输送管、结构管，目前，在 世界焊接钢管的产量中，ERW焊管产量约占焊管总产量的80％左右。
