MS ERW (Mild Steel Electric Resistance Welded) pipes are produced by forming cold-rolled mild steel strips into tubes and fusing the seam via high frequency electric resistance welding . Available in diameters from �½ to 24 with wall thicknesses between 1.8- 12.7-mm, they come in standard 6-m lengths (customizable) and black mill finish, with optional galvanized coating .
These pipes deliver excellent tensile (330- 410-MPa) and yield (210- 240-MPa) strength, plus dimensional accuracy, cost efficiency, and recyclability . They are widely used in construction, water & gas distribution, industrial framing, agricultural irrigation, and automotive structures.

SV Trade has diversified into supplying & Exporting of Carbon Steel High Frequency Welded (HFW) / Electric Resistance Welded (ERW) Pipes.
HFW pipes are made from hot rolled flat steel strip, formed into tubular shape and the longitudinal seam is welded by the application of heating the edges through High Frequency Induction coil and by squeezing the edges. The weld joint is achieved without addition of any filler metal.
