Advantages of High Frequency Straight Seam Welded Pipe
(1) High frequency straight seam welded pipe forming process is small rebound, the remaining stress is small. (2) Deformation hardening effect is small, the whole circle after the geometric standard is accurate, conducive to ensuring the construction and welding quality. (3) High frequency straight seam welded pipe weld shape is good, not prone to undercut, the surface welding is not a medium defect. (4) High frequency straight seam welded pipe bead distribution in the circumference of a point, therefore, according to the requirements of the weld on the favorable position.
