The tube mill is non-standard product and we can design and produce it according to your requirements. The following is some techinical parameters about one type of the mill. For more information, please feel free to contact us.
I. Summary
The mill is intended for manufacturing of round pipe of Φ89mm-Φ219mm with thickness of 2.0mm–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.
