The main technical characteristics of spiral steel pipe:
During the forming process of the spiral steel pipe, the steel plate is uniformly deformed, the residual stress is small, and there is no scratch on the surface. The processed spiral steel pipe has greater flexibility in the range of diameter and wall thickness, especially when producing high-grade thick-walled pipes, especially small and medium-diameter thick-walled pipes, its advantages are unparalleled by other processes, which can make customers satisfied. There are more requirements for spiral steel pipe specifications.
The spiral steel pipe adopts the advanced double-sided submerged arc welding process, which can realize welding at the ideal position, is not prone to defects such as edge errors, welding deflection, and insufficient welding, and is 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 tested and monitored, and the product quality is effectively guaranteed.
