Difference between Seamless & ERW Stainless Steel pipe

Electric Resistance Welding (ERW) pipe is manufactured by rolling metal and then welding it longitudinally across its length. Seamless pipe is manufactured by extruding the metal to the desired length; therefore ERW pipe have a welded joint in its cross-section, while seamless pipe does not have any joint in its cross-section through-out its length.Difference between ERW, DOM and Seamless Tube | Metal erw pipes and tubes hot rollingMay 12, 2015 · This month we take a hard look at the differences between ERW, DOM and Seamless Tube.
