ERW PIPES & TUBES
ERW (Electrical Resistance Welding) pipes are manufactured by cold forming of steel coil into a round cylindrical shape. ERW steel pipes and tubes are available in various qualities, wall thicknesses, finish and diameter.
Initially it was done with the low frequency A.C current to heat the edges. Now the low frequency process has changed to high frequency to produce a higher quality weld.
