Introduction To The Advantages Of Spiral Welded Steel Pipes

1. Steel pipes of different diameters can be produced using strip steel of the same width, especially narrow strip steel can be used to produce large diameter steel pipes.
2. Under the same pressure conditions, the stress endured by spiral welds is smaller than that of straight seams, which is 75% to 90% of straight seam welded pipes, so it can withstand greater pressure. Compared with straight seam welded pipes with the same outer diameter, the wall thickness can be reduced by 10% to 25% under the same pressure.
3. The dimensions are accurate. Generally, the diameter tolerance does not exceed 0.12%, the deflection is less than 1/2000, and the ovality is less than 1%. Generally, the sizing and straightening processes can be omitted.
4. It can be produced continuously. In theory, it can produce infinitely long steel pipes. The loss of head and tail cutting is small, and the metal utilization rate can be increased by 6% to 8%.
5. Compared with straight seam welded pipes, it is flexible to operate and easy to change and adjust varieties.
6. The equipment is light in weight and requires low initial investment. It can be made into a trailer-type mobile unit to produce welded pipes directly at the construction site where pipelines are laid.
7. Easy to realize mechanization and automation.
