During the forming process of spiral steel pipes, the steel plate is uniformly deformed, the residual stress is small, and there are no scratches on the surface. The processed spiral steel pipe has greater flexibility in the diameter and wall thickness range, especially when producing high-grade thick-walled pipes, especially small and medium-caliber thick-walled pipes, its advantages are unparalleled. Other processes can satisfy users. There are more requirements for the specifications of spiral steel pipes.

The spiral steel pipe adopts an advanced double-sided submerged arc welding process, which can achieve welding in the ideal position, is not prone to defects such as edge errors, welding deflection, or insufficient welding, and is easy to control welding quality.

100% quality inspection of steel pipes enables the entire process of steel pipe production to be effectively detected and monitored, effectively ensuring product quality.

All equipment in the entire production line has the function of networking with the computer data acquisition system to realize the instant transmission of data, and the technical parameters in the production process are controlled by the central control room.
