Teneng - Model ERW426 -Steel Pipe Making Machine
The mill is intended for manufacturing round pipe of Φ89mm-Φ273mm with thickness of 4.0mm–12.0mm 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:
{Steel Tape}→→ Double-head un-coiler→→Five-roll Flattener →→Strip-head Cutter and welder→→Horizontal spiral accumulater →→Forming section(Flattening unit +Main driving unit +Forming unit +Guide unit +High frequency induction welding unit +squeeze roller)+ De-burr frame →→seam annealer→→Cooling unit →→ Sizing unit and straightener →→Flying saw under computer-control →→ Run-out table
