ZG50 tubes and pipes making machine The thickness of steel strip: 0.8-2.5mm (As per GB708-88) The width of steel strip: 50-20

Overview

This equipment is specially used for producing Φ15-Φ63.5 mm,   δ0.8-2.5mm high-frequency straight welded pipe and corresponding square pipe and special-shaped pipe (δ≤2.0mm). 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.

Applicable material

 

Hot or cold-rolled steel strip (As per GB700-88)Material: Low-carbon steel, low alloy steelThe thickness of steel strip: 0.8-2.5mm (As per GB708-88) The width of steel strip: 50-200mm I.D. of steel coil: Φ450-Φ550mmO.D. of steel coil: Φ800-Φ1200mmMaximum weight coil: 1500kg

Dimension range of processing steel pipe

 O.D.: Φ15-Φ63.5mmWall thickness: 0.8-2.5mm (square pipe and special-shaped pipeδ≤2.0 mm)  if using material Q345 (≤645Mpa, ≤380Mpa), the thickness should be: 0.8-2.0mm; square and rectangular pipe≤1.6mmLength: 4-8M

Product (steel pipe) process flow

 

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

 

Milling speed:20-80M/min

High-frequency electrics power:150 KW (solid state)
