High Precision ERW Round Tube Carbon Steel Galvanized Pipe Welded Making Machine
Summary of Pipe Welding Machine
The accurately sized strips, precut from high quality hot-rolled or cold-rolled steel coil strips in slitting machine, are fed into the tube mill, gradually formed to a round profile with open seam along its length in the forming mill.
A high-frequency induction welding technique is adopted to seam edge heat and longitudinal seam weld, form a strong continuous seam joint.
The strip is continuously seam welded while round in shape. The welded pipe passes through and external bead scarfing and cooling, further sizing and shaping to round or square or rectangular section with specified tolerance in the sizing mill.
After that, the endless welded pipe will be on-stream cut to desired and measured lengths.
Finished tubes may be of round, square or rectangular shape.
