High speed 8-32mm Welding Pipe Round Square Tube Making Machine With Fly Saw Cutting And Water Cooling

General information

This equipment is specially used for producingΦ8-Φ32mm,δ0.5-1.5 mm High-frequency straight seam welded pipe and corresponding square pipe and special-shaped pipe(δ≤1.2mm). The composition of equipment is from decoiler to fixed length cutting saw. Rolling speed can be adjusted correspondingly within suitable range of pipe diameter and wall thickness.
