RT530×13 high-frequency longitudinal welded pipe production line is mainly used for the production of round pipe φ219~φ530mm, wall thickness 4.0~13.0mm, square tube 170×170 - 400×400mm, wall thickness 4-10mm, and rectangular tube 260×130 - 400×200mm, wall thickness 4-10mm.

It adopts high-frequency induction welding and straight seam welding. Its working principle: weld the edge of the pipe when heated in a magnetic field, and then compress the edge in automatic mode, and the pipe moves continuously along the production line.

This ERW high-frequency welding pipe mill is specialized equipment to produce high frequency straight seam welded pipes for structural pipe and industrial pipe. Through optimization design, best materials choice, and accurately fabrication and rolls, the whole line can be reached high precision and high speed. Within suitable range of pipe diameter and wall thickness, pipe production speed can be adjusted.

The pipes is mostly used for petroleum, Natural gas, city gas, pipe network, chemical industry, electricity, steel truss, water and gas pipe line; it is widely used for a variety of pressure pipelines.
