ERW vs CEW Steel Pipes

Manufacturing Process. Electric Resistance Welded (ERW) and Cold Drawn Electric Welded (CEW) pipes differ significantly in their manufacturing processes. ERW pipes are formed by heating the steel strip and passing it under rollers to shape it into a cylinder. The edges are then welded together using an electric charge to fuse the material.
