High-frequency welded pipes High-frequency welded pipes are generally straight-slit, but straight-slit welded steel pipes are not necessarily high-frequency welded. The large round tube mill series of Huaye is mainly designed and developed to meet the demand of customers for producing architectural structure tubes (Q235 material) less than 20mm, oil delivery tubes and other products. The high-frequency resistance welded steel pipe is different from the ordinary welded pipe welding process. The weld is made of the base material of the steel strip body, and the mechanical strength is better than that of the general welded pipe.
