摘要
介绍了采用预精焊工艺生产螺旋埋弧焊管的工艺特点及工业化生产优势。针对预精焊螺旋成型递送速度快的特点,对原材料、装备水平、成型工艺参数、调型试车质量和生产监控调整等影响成型稳定性的因素进行了系统分析,提出了有效的控制措施和解决办法,对螺旋焊管预焊技术的深化应用、预焊机组的工艺(设备)设计及预焊管现场生产具有一定的借鉴及指导意义。
In this article, it introduced technology characteristics and industrial production advantage of SAWH pipe by two-step welding process. Aiming at high-speed helical forming of two-step welding, it carried out systematic analysis on influencing forming stability factors, such as raw material, equipment level, forming parameters, commissioning quality and production monitoring adjustment etc. Some effective control measures were put forward, which provided a certain reference and guidance for further application of SAWH pipe, the pre-welding unit process（equipment）design and the pre-welding pipe production.
