This specialized equipment is designed for producing high-frequency straight seam welded pipes with diameters ranging from Φ60-Φ165mm and wall thicknesses of 3-7mm, including corresponding square pipes and special-shaped pipes (δ≤2.0mm). The complete production line includes all components from the uncoiler to the fixed length cutting saw, with adjustable rolling speed optimized for different pipe diameters and wall thicknesses.
The high-frequency straight seam welded pipe production line processes steel strips through a series of precision operations: the steel strip is fed through rollers to form a tube billet, then welded using high-frequency proximity and skin effects to instantly heat the strip edges to welding temperature. The welded pipe then undergoes water cooling, sizing, and straightening to meet exact specifications.
