High-frequency welded pipe production line is a complete set of metal pipe production equipment that forms various metal pipe raw materials (plain carbon steel, aluminum, stainless steel, non-ferrous metals, etc.) into round pipes, square pipes, special-shaped pipes, etc. through extrusion deformation and other means, welds them using high-frequency induction welding technology, sizing the welded pipes with extrusion rollers (to produce various pipe diameters), and cutting the pipes to the required length with cold-cut flying saws to obtain metal pipe products.
