Product features

Main process features:

1. During the forming process, the steel plate is uniformly deformed, the residual stress is small, and the surface is not scratched. The processed spiral steel pipe has greater flexibility in the size and specification range of diameter and wall thickness, especially in the production of high-grade thick-walled pipe, especially small and medium-diameter thick-walled pipe, which has incomparable advantages in other processes, which can meet more requirements of users in the specification of spiral steel pipe.

2. Using the advanced double-sided submerged arc welding process, welding can be realized in the ** position, which is not easy to appear defects such as wrong edge, welding deviation and not welded through, and it is easy to control the welding quality.

3. Carry out 100* quality inspection of steel pipe, so that the whole process of steel pipe production is under effective detection and monitoring, which effectively ensures product quality.

4. All equipment of the whole production line has the function of networking with the computer data acquisition system to realize the real-time transmission of data, and the technical parameters in the production process are controlled by the ** control room.
