摘要
介绍了一种中小直径直缝埋弧焊管的制造方法,其主要步骤包括钢带开卷、对接、板边加工、成型、在线连续预焊、切管、埋弧自动焊精焊、精整等。该方法的关键技术在于以钢带为原料,采用HFW管的连续成型方法,尤其适合于中小直径直缝埋弧焊管的生产,且生产效率高、成本低,产品质量优良。
Elaborated in the article is a manufacturing process for smalb＇medium-sized SAWL pipes that contains such major operation steps as decoiling of strip steel, butting, plate edge processing, forming, online continuous pre-welding, pipe cutting, automatic submerged arc fine welding, and finishing. The key techniques of this process are using strip steel as raw material, and employment of the continuous forming method as used for manufacturing HFW pipes. This process is particularly suitable for production of small/medium-sized SAWL pipes, featuring high productivity, low operation cost, and excellent product quality.
