Main process characteristics of spiral steel pipes:

During the molding process, the steel plate deforms uniformly with minimal residual stress and no surface scratches are produced. The processed spiral steel pipes offer greater flexibility in diameter and wall thickness specifications, particularly in the production of high-grade thick-walled pipes, especially medium and small diameter thick-walled pipes, where they have advantages that other processes cannot match. They can meet customers' more varied requirements for spiral steel pipe specifications.

b. Utilizing double-sided submerged arc welding technology, welding can be achieved in position, reducing the likelihood of defects such as misalignment, weld offset, and incomplete penetration, 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 ensuring product quality.

d. The entire production line's equipment is 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.
