The RT76 tube mill is intended for manufacturing of round/square pipe of Φ25mm-Φ90mm with

Thickness of 1.5mm–4.0mm from cold-rolled, hot-rolled and galvanized coil strip.

Features of RT76 Pipe Making Machine

This RT76 Steel pipe making machine is used to produce industrial steel pipes 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, rectangular pipe or special pipe LTZ and D shape.
