erw steel pipe straight to seam welded tube
Difference between Seamless & ERW Stainless Steel pipe
ERW (Electric Resistance Welded) pipes are welded longitudinally, manufactured from Strip / Coil and can be manufactured upto 24” OD. ERW pipe cold formed from a ribbon of steel pulled through a series of rollers and formed into a tube which is fused through a electric charge.

Double seam saw pipe is havening a two weld seam opposite to each other. Both the seams are welded from inside and outside of the pipe. In the case of high thickness pipe, multiple pass welding is done. In a spiral saw pipe, steel plate from the de coiler is formed in a spiral loop. This spiral loop is then welded from inside and outside of the pipe.
