Product Description:

HG76 Carbon steel tube mill for diameter 10-89mm

Summary of Carbon steel tube mill

The mill is intended for manufacturing of round pipe of Φ20mm-Φ89mm with thickness of 1.0mm–3.5mm 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.
