During the forming process of the spiral tube, the deformation of the steel plate is uniform, the residual stress is small, and the surface is not scratched. The machined spiral steel pipe has greater flexibility in the size specification range of diameter and wall thickness. Especially in the production of high-grade steel thick-walled pipes, especially small and medium-diameter thick-walled pipes, it has incomparable advantages in other processes, and can meet more requirements of users in terms of spiral steel pipe specifications.
Using the advanced double-sided submerged arc welding process, the welding can be realized in the best position, and it is not easy to have defects such as misalignment, welding deviation and incomplete penetration, and it is easy to control the welding quality.
