    ERW Pipe Manufacturering Process:


    Straight seam high frequency welded pipe (ERW steel pipe) is formed by forming a hot-rolled coil through a forming machine. The skin effect and proximity effect of high-frequency current are used to heat and melt the edge of the pipe blank. Pressure welding is carried out under the action of a squeeze roller. Realize production. Welded steel pipes have simple production process, high production efficiency, many varieties and specifications, and less equipment, but their general strength is lower than seamless steel pipes.
