114mm Automatic erw pipe mill
Product Detailed
welded pipe mill line pipe production line pipe mill Used for making ERW pipes

I. Summary

The mill is intended for manufacturing of round pipe of Φ25mm-Φ114mm with thickness of 1.2mm–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.
