Chinese tube production machine/tube roll forming mill line

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.
