Helicoidal steel pipes are manufactured from steel strip coils, formed through cold extrusion, and then焊接 using the automatic double-spiral double-sided submerged arc welding process. The steel strip is fed into the pipe welding unit, where it passes through multiple roller rolls, gradually coiling into a circular billet with an open gap. The pressure of the extrusion rolls is adjusted to control the weld gap between 1~3mm, ensuring the ends of the weld are flush.

Changzhou Hengtai Pipeline Technology Co., Ltd. is one of the major enterprises in Hebei Province specializing in steel pipes and pipeline accessories. The company is registered with a capital of 50 million RMB and is located in the Zhenggang Industrial Park of Yanshan Economic Development Zone in Yanshan County, Cangzhou City, Hebei Province, known as the "China Pipeline Equipment Manufacturing Base."
