HF Welded Pipe Mill / ERW Pipe Line

  HF Welded Pipe Mill / ERW Pipe Line Core Value HF induction welding plus cold forming to produce high-strength pipes with a "seamless feel." Why You Need It Stronger Welds:​ Penetrates deeper than regular welding, offering pressure resistance close to seamless pipes. Smooth Inner Wall:​ Minimal burr inside ensures low fluid resistance, perfect for transmission lines. Extreme Speed:​ Welding speed exceeds 100 m/min—dozens of times faster than TIG welding. Key Selling Points Solid-State HF Power:​ 30% more energy-efficient than vacuum tube types; no warm-up needed. Induction Heating:​ Instant fusion via skin effect minimizes heat-affected zones (HAZ). Auto Scarfing:​ Inside/outside burrs automatically removed; no secondary polishing required. High-Speed Flying Saw:​ PLC synchronous tracking ensures precise cutting without pile-up. Typical Applications Fluid Pipes:​ Oil casing, gas pipelines, water supply, hydraulic support pipes. Structural Pipes:​ Highway guard…
