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.
