Hebei Spiral Steel Pipe Factory Spiral steel pipes manufactured by Zhongyuan Pipeline Manufacturing Co., Ltd. have been widely adopted and are commonly used in oil and natural gas transmission pipelines. Furthermore, to better ensure… Hebei Spiral Steel Pipe Factory The spiral steel pipes manufactured by Zhongyuan Pipeline Manufacturing Co., Ltd. are, during their production process, by… Hebei Spiral Steel Pipe Factory The spiral welded steel pipes manufactured by Zhongyuan Pipeline Manufacturing Co., Ltd. meet specific requirements for the steel strip, which can enhance the weldability of the pipe. Consequently, reducing the carbon content and lowering the sulfur level in the steel helps improve the pipe’s ductility and crack‑resistance. It also minimizes the incorporation of sulfide inclusions and enhances the steel’s resistance to cracking. At the same time, it reduces sulfur content and improves the quality of the steel strip components.
Hebei Spiral Steel Pipe Factory The production process for spiral welded steel pipes manufactured by Zhongyuan Pipeline Manufacturing Co., Ltd. is as follows:
1. Inspection of raw materials: steel coils, welding wire, and welding machines.
