square tube forming machine


1. Description

This equipment is specially used for producing Φ25-Φ100mm, 1.0-4.0mm high-frequency straight seam welded tube and corresponding square tube and special-shaped tube (δ≤3.0mm). The composition of equipment is from uncoiler to fixed length cutting saw. Rolling speed can be adjusted correspondingly within suitable range of tube diameter and wall thickness.


2. Applicable material:

(1) Hot or cold-rolled steel strip

(2) Material: Q235, Q345B

(3) The thickness of steel strip: 1.0-4.0mm

(4) The width of steel strip: 80-280mm

(5) I.D. of steel coil: Φ450-Φ550mm

(6) O.D. of steel coil: Φ800-Φ1500mm

(7) Maximum weight coil: 4000kgs


3. Dimension range of processing steel tube:

(1) O.D.: Φ25-Φ100mm

(2) Wall thickness: 0.7-4.0mm (square tube and special-shaped tube δ≤3.0mm)

(3) Length: 4-8M


4. Milling speed: 20-70M/min(choose different speed as per different pipe diameter and thickness)


5. Product (steel tube) 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 tube
