ZG76 Pipe making machine the machine is used for producing25-80mm, 1.2-4.0mm high-frequency straight seam welded pipe

Machine unit for high-frequency straight seam welded pipe 

1.1 Summary:

This equipment is specially used for producingΦ25-Φ80mm, δ1.2-4.0mm high-frequency straight

seam welded pipe and corresponding square pipe and special-shaped pipe (δ≤3.25mm). 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.

1.2 Applicable material:

(1)Hot or cold-rolled steel strip (As per GB700-88 or GB1591-88)

(2)Material: Low-carbon steel, low alloy steelδs≤345Mpa, δb≤610Mpa

(3)The thickness of steel strip: 1.2-4.0mm (As per GB708-88)

(4)The width of steel strip: 78-250mm

(5)I.D. of steel coil: Φ450-Φ550mm

(6)O.D. of steel coil: Φ800-Φ1200mm

(7)Maximum weight coil: 2500kgs

1.3 Dimension range of processing steel pipe:

(1)O.D.: Φ25-Φ80mm

(2)Wall thickness: 1.2-4.0mm (square pipe and special-shaped pipeδ≤3.25mm)

(3)Length: 4-8M

1.4 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 → finished pipe→ run-out table
