Why Choose Spiral Welded Pipe?

Under the same pressure conditions, the stress of the spiral welded seam is smaller than that of the straight seam, which is 75% to 90% of that of the straight seam welded pipe, so it can withstand greater pressure. Compared with the straight seam welded pipe of the same outer diameter, the wall thickness can be reduced by 10% to 25% under the same pressure. The size is accurate, the general 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 process can be omitted. Continuous production is possible. In theory, long steel pipes can be produced, with small head and tail loss, and can increase the metal utilization rate by 6% to 8%. The equipment is light in weight and low initial investment.

Advantages of spiral welded pipe
(1) It is possible to use the same width of strip steel to produce steel pipes of different diameters, and also to use narrower strips to produce large-diameter steel pipes.
(2) Under the same pressure condition, the stress of spiral welded seam is smaller than that of straight seam welded seam, which is 75% to 90% of that of straight seam welded pipe, so it can withstand greater pressure. Compared with straight seam welded pipe of the same large diameter, the wall thickness can be reduced by 10% to 25% under the same pressure.
(3) Dimensional accuracy, diameter tolerance of not more than 0.12%, deviation of less than 12,000, ellipticity of less than 1%, generally eliminate the sizing and straightening process.
(4) Continuous production, theoretically can produce long steel pipe, small head and tail loss, metal utilization can be increased by 6% to 8%.
