High frequency straight seam welded pipe production line

Performance:

The mill is intended for manufacturing of round pipe of Φ50.8mm-Φ101.6mm with thickness of 1.0mm–3.5mm 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.

II. The technical flow of the production line

{SteelTape}  →  Double-head un-coiler  →  Strip-head Cutter and welder  →  

Cage Loop  →  Forming section(Flattening unit +Main driving unit +Forming unit +Guide unit +High frequency induction welding unit +squeeze roller)+ De-burr frame  →  Zinc Pinting machine   →  Cooling unit   →   Sizing unit and straightener   →  Flying saw under computer-control  →  Run-out table
