ERW Pipe Plant
- ERW (Electrical Resistance Welding) pipes are manufactured by cold forming of steel coil into a round cylindrical shape. In the initial times it was done with the low frequency A.C. current to heat the edges. Now, since 1970 the low frequency process changed to high frequency A.C. current to produce a higher quality weld.
- 24 inch dia, 16mm thick ERW pipes are formed by using continuous coil to coil joining. The machine has got 14 sets of VFD’s of various capacities.
Major Applications: Water Pipelines,Agriculture & irrigation (Water mains, industrial water pipe lines, plant piping, deep tube-wells & casing pipes, sewerage piping), Gas pipe lines,LPG and other non-toxic gas lines
