HG114 welded pipe making machine

الوصف

I. Summary

The mill is intended for manufacturing of round pipe ofΦ*0mm-Φ**4mmwith thickness of 1.5mm–5.0mm 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.

The manufacturing process provides for the uses of coiled strip precut in required width sizes in slitting machine.
