High-frequency straight seam welded steel pipes can be divided into straight seam high-frequency resistance welded steel pipes and straight seam high-frequency induction welded steel pipes according to different high-frequency welding processes. The forming process generally adopts roll bending cold forming method.
High-frequency straight seam welded steel pipes are generally produced in smaller diameters, generally less than 660mm or 26 inches in outer diameter. Its characteristics are: fast welding speed, for example, for steel pipes with an outer diameter of less than 1 inch, the welding speed can reach up to 200 m/min.
