1. During the forming process, the steel plate deforms uniformly, with low residual stress and no scratches on the surface. The processed spiral steel pipe has greater flexibility in the size range of diameter and wall thickness, especially in the production of high-grade thick walled pipes, especially small and medium-sized thick walled pipes, which have advantages that cannot be compared with other processes, and can meet more requirements of users in terms of spiral steel pipe specifications.
2. By adopting advanced double-sided submerged arc welding technology, welding can be achieved at the optimal position, without defects such as misalignment, welding deviation, and incomplete penetration, making it easy to control welding quality.
3. 100% quality inspection is carried out on steel pipes, ensuring that the entire production process of steel pipes is under effective inspection and monitoring, effectively ensuring product quality.
4. All equipment on the entire production line has the function of networking with the computer data acquisition system to achieve real-time data transmission, and the technical parameters during the production process are monitored by the central control room.
