Product Advantages
Advantages of spiral welded pipe:
(1) Steel pipes of different diameters can be produced using strip steel of the same width, and
steel pipes of large diameter can be produced from narrow strip steel.
(2) 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.
(3) 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.
(4) 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%.
(5) The equipment is light in weight and low initial investment. It can be made into a trailer-type mobile unit to directly
produce welded pipes at the construction site where the pipeline is laid.
