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.Difference Between Seamless and Welded/ERW PipesPerformance and Usage: Seamless steel pipe has better pressure capacity, strength is higher than ERW welded steel pipe. So it is widely applied in high pressure equipment, and thermal, boiler industries. Generally the welding seam of the welded steel pipe is the ERW Pipe, Electric Resistance WeldedElectric Resistance Welded (ERW) pipe is manufactured by cold forming a flat steel strip into a rounded tube by passing it through a series of forming rollers to obtain a longitudinal seam. The two edges are then simultaneously heated with a high frequency current and squeezed together to produce a
