Chinese tube production machine/tube roll forming mill line
Basic information of welded pipe Roll Forming Machine:
1. Round Pipe diameter: Φ38 –Φ102mm
Pipe Thickness: 1.0 – 5.0mm
2. Square Pipe: 20X20mm – 80X80mm
Rectangle Pipe: 20X30mm – 60X80mm
Pipe Thickness: 1.0 – 3.0mm
3. Pipe Length: 6.0m – 12.0m
4. Length Tolerance: 0-6mm
The mill is intended for manufacturing of round pipe of Φ38mm-Φ102mm with thickness of 1.0mm–3.0mm from cold-rolled and hot-rolled coil strip by means of unclosed tubular blank with its subsequent welding into tube, edge heating by means of solid state high-frequency welder, longitudinal seam welding in rolls of tube welding machine, cooling, further sizing or shaping and on-stream cutting of endless tube in measured lengths. Finished product will be of round, square or rectangular pipe.
