HG76 ERW carbon steel pipe making machine
The mill is intended for manufacturing of round pipe of Φ25mm-Φ76mm with thickness of 1.2mm–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 pipe, square and rectangle pipe.
The technical flow of the production line:
{SteelTape}→→ Double-head un-coiler →→Strip-head Cutter and welder→→Spiral accumulator→→Forming section (Flattening unit +Main driving unit +Forming unit +Guide unit +High frequency induction welding unit +squeeze roller) + De-burr frame →→Cooling unit →→ Sizing unit and straightener →→Cold saw under computer-control →→ Run-out table→→ Semi-auto Packing machine
