ZG90 pipe or tube making machine

ZG90 pipe or tube making machine The thickness of steel strip: 1.5-4.5mm (As per GB708-88) The width of steel strip:100-320mm

1.1 Summary

This equipment is specially used for producingΦ32-Φ102mm, δ1.5-4.5mm high-frequency straight seam welded pipe and corresponding square pipe and special-shaped pipe (δ≤3.5mm). The composition of equipment is from uncoiler to fixed length cutting saw. Rolling speed can be adjusted correspondingly within suitable range of pipe diameter and wall thickness.

1.4 Product (steel pipe) process flow

Raw material (steel coil) → uncoiling → shearing and end welding → material accumulating → non-power leveling →mill-forming→ high-frequency welding → removing burrs outside of weld seam → cooling → sizing → roughly straightening → fixed length cutting → finishing pipe

1.5 Milling speed: 15-50M/min

1.6High-frequency equipment power: 300 KW (Solid state)
