Hydraulic vertical 3 roller or 7 roller copper tube coil bending machine, copper pipe coil making machine
High efficiency carbon steel Round / Square Shaped pipe making machine
The mill is intended for manufacturing of round pipe of Φ25mm-Φ76mm with thickness of 1.2mm–4.0mm 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 pipe, square and rectangle pipe.
The technical flow of the production line:
