(1) low springback and residual stress in the forming process of straight seam high-frequency welded steel pipe.
(2) the deformation hardening effect is small, the geometric size is accurate after the whole circle, which is conducive to ensure the construction and welding quality.
(3) the straight seam high frequency welded steel pipe has good shape, not easy to appear bite edge, internal and external welding correct medium defect.
(4) the straight seam steel pipe passes are distributed at a point on the circumference, so the welding seam can be placed in a favorable position according to the requirements of use.
