During the forming process, the steel plate deforms uniformly with minimal residual stress and no surface scratches are produced. The spiral steel pipes processed offer greater flexibility in diameter and wall thickness specifications. They possess unparalleled advantages in producing high steel grade thick-walled pipes, especially medium and small diameter thick-walled pipes, and can meet customers' more diverse requirements for spiral steel pipe specifications.

b. Utilizes advanced double-sided submerged arc welding technology, allowing for spot welding with reduced risk of misalignment, welding offset, and incomplete penetration defects, making it easy to control welding quality.

c. Conduct quality inspections on steel pipes to ensure the entire production process is under effective testing and monitoring, thereby effectively guaranteeing product quality.

d. The entire production line is equipped with devices capable of connecting to a computer data collection system, enabling real-time data transmission and centralized control room monitoring of technical parameters during the production process.
