The φ127mm welded pipe making line is used to produce steel pipes of φ48mm-127mm in OD and 1.5-5.0mm in thickness, as well as corresponding square and rectangular pipe. The welded pipe making line 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.
