What are the main process characteristics of spiral steel tube

1. During the forming process, the steel plate has uniform deformation, small residual stress and no scratch on the surface. The processed spiral steel tube has greater flexibility in the size and specification range of diameter and wall thickness, especially in the production of high-grade thick wall steel tube, especially in the small and medium-sized thick wall steel tube, which has advantages that other processes can not match, and can meet more requirements of users in the specification of spiral steel tube.

2. The spiral steel tube adopts the advanced double-sided submerged arc welding technology, which can realize the welding at the best position, and is not easy to have defects such as staggered edge, welding deviation and incomplete penetration, and easy to control the welding quality.

3. Carry out 100% quality inspection on spiral steel tube, so that the whole process of steel tube production is under effective detection and monitoring, and effectively ensure the product quality.

4. All equipment of the whole spiral steel tube production line has the function of networking with the computer data acquisition system, realizing the real-time data transmission, and the central control room is responsible for the technical parameters in the production process.
