The mill is intended for manufacturing pipe of 50X50mm-200X200mm with thickness of 1.5mm–8.0mm 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 productwill be of square and rectangle pipe.

The Technical Flow of the Production Line

{Steeltape}→ Un-Coiler → Flattening → 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)+ Removing External Burr → Cooling Unit → Sizing Unit and Straightener → Cutting Saw Under Computer-Control → Packing Machine & Run-Out Table
