1. During the forming process, the steel plate deforms uniformly, with low residual stress, and no surface scratches. The manufactured spiral steel pipes offer greater flexibility in diameter and wall thickness specifications, especially in producing high-grade thick-walled pipes, particularly medium and small-diameter thick-walled pipes, providing advantages unmatched by other processes and meeting more user requirements for spiral steel pipe specifications.

2. By using advanced double-sided submerged arc welding technology, welding can be performed at the optimal position, reducing defects such as edge mismatch, weld deviation, and incomplete penetration, making it easier to control welding quality.

3. A 100% quality inspection is conducted on the steel pipes, ensuring that the entire production process is effectively monitored and controlled, thereby ensuring product quality.

4. All equipment on the production line is capable of networking with a computer data acquisition system, allowing real-time data transfer, with technical parameters of the production process controlled from a central control room.
