ERW tube mill line

Description

The mill is designed by FF type or cage forming or rolling type forming method to manufacture round, rectangular and square tube 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.
