Description

I. Summary

The mill is used to manufacture of round pipe of Φ8mm-Φ32mm with thickness of 0.5mm-2.5mm 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.
