ERW Pipe Production Line

Product Name: ERW Pipe production line

Specification of Round Pipe Mill: φ89

The pipe production mill is φ89， specially designed to manufacture of round pipe of Φ25mm-Φ89mm with thickness of 1.0mm-4.0mm 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.
