SS ERW Pipe

SS 304 ERW pipes are welded lengthways. SS 304 ERW pipes are factory-made from Strip / Coil.ERW pipe cold shaped from a ribbon of steel force through a series of rollers and shaped into a tube that is amalgamate through a charge.

SS 304 ERW pipes are used in various industrial processes. SS 304 ERW pipes areavailable in varied qualities, wall thicknesses, and diameters of the finished pipes.ERW pipes means Electric Resistance Welded Pipes.A plate is rolled to become a pipe and welded using resistivity fastening method.
