ERW Pipe Manufacturing Process - Sunny Steel

ERW Pipe Manufacturing Process. Electric resistance welded (ERW) pipe is manufactured by cold-forming a sheet of steel into a cylindrical shape. Current is then passed between the two edges of the steel to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material.ERW Steel Pipe, ERW Welded PipeEastern Steel ProductsElectric Resistance Welding Pipe (ERW steel pipe) is hot-rolled coil after forming machine, the use of high-frequency current skin effect and proximity effects, the tube edge heating and melting, squeeze roller under pressure welding to achieve production.
