This Pipe seam welding mill machine is specially used for producing Φ16-Φ63mm, δ1.0-3.0mm high-frequency straight seam welded pipe and corresponding square pipe and special-shaped pipe (δ≤2.5mm).The composition of Pipe seam welding mill machine is from uncoiler to fixed length cutting saw. Rolling speed can be adjusted correspondingly within suitable range of pipe diameter and wall thickness.

Pipe seam welding mill machine material:
(1)Hot or cold-rolled steel strip (As per GB708-88)
(2)Material: Low-carbon steel, low alloy steel, galvanized steel.
(3)The thickness of steel strip: 1.0-3.0mm (As per GB708-88)
(4)The width of steel strip: 50-200mm
(5)I.D. of steel coil: Φ450-Φ550mm
(6)O.D. of steel coil: Φ800-Φ1200mm
(7)Maximum weight coil: 1500kgs

1.3Dimension range of processing steel pipe:
(1)D.: Φ16-Φ63mm
(2)Wall thickness: 1.0-3.0mm (square pipe and special-shaped pipe≤2.5mm)
(3)Length: 4-8m

Pipe seam welding mill machine 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
Milling speed: 20 - 60m/min
1.5High-frequency equipment power: 200 KW(Solid state)
