HF Welded Pipe Making Machine



2.machine Summary

Finished product will be of round, square or rectangular pipe.The mill is intended for manufacturing of round pipe of Φ38mm-Φ127mm with thickness of 1.5mm5.0mm from cold-rolled and hot-rolled coil strip by means of un closed 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. This machine can be made into different sizes of tube by changing the molds.
