Description: Straight seam high frequency welded steel pipe technology is relatively simple, rapid continuous production of the characteristics of a wide range of applications in civil construction, petrochemical, light industry and other sectors. Used for the transportation of low-pressure fluid, or made into a variety of engineering components and light industrial products.

 
Straight seam high-frequency welded steel pipe forming advanced technology, reliable quality, good welding position and stability of the welding parameters, welding speed, high output, the entire production line equipment and technology are world-class level.
Features
The rebound in the molding process (1) Straight seam high frequency welded steel pipe, the residual stress.
(2) The strain hardening effect is small, precise geometric dimensions in the whole circle, helping to ensure the quality of construction and welding.
(3) Straight seam high frequency welded steel pipe weld bead shape, not prone to biting edge, inside and outside weld misalignment defects.
(4) straight seam steel pipe weld distribution in the circumference of a point, and therefore can be used to weld on a favorable position.
