During the forming process of the spiral steel pipe
, the steel plate is uniformly deformed, the residual stress is small, and the surface has no scratches. The processed spiral steel pipe
has more flexibility in the diameter and wall thickness size range, especially in the production of high steel grade thick wall pipes, especially small and medium diameter thick wall pipes, its advantages are unmatched by other processes, which can make User satisfaction. There are more requirements for spiral steel pipe
The spiral steel pipe
adopts the advanced double-sided submerged arc welding process, which can realize the welding in the ideal position, and is not easy to have defects such as edge error, welding skew, insufficient welding, and easy to control the welding quality.
100% quality inspection is carried out on the steel pipe so that the whole process of steel pipe production can be effectively detected and monitored, and the product quality is effectively guaranteed.
All equipment of the entire production line has the function of networking with the computer data acquisition system to realize real-time data transmission, and the technical parameters in the production process are controlled by the central control room.
