Product Description

Production Information : ERW (Electrical Resistance Welding) pipes are manufactured by cold forming of steel coil into a round cylindrical shape


ERW Pipes

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.


ERW pipes have various applications like fencing, line pipe, scaffolding etc. ERW steel pipes are available in various diameters, wall thickness, finish and grades


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
