Black & Galvanized [ISI] ERW Steel Tubes
EW (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 Application
- Water pipelines
- Agriculture & irrigation
- Gas pipe lines
- LPG and other non-toxic gas lines
