Q235 steel welded tube roll forming machine/iron pipe tube rolling machine

I. Summary

The mill is intended for manufacturing of round pipe of Φ10mm-Φ89 mm with thickness of 0.4mm–6.0mm 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.
