Differences between ERW Steel Pipe and HFW Steel Pipe

ERW have low, medium, high frequency welding processes, and HFW is specially for high-frequency electric resistance welding . The differences between ERW and HFW steel pipe , is EFW is a type of ERW process for ordinary and thin-wall thickness steel pipes . ERW pipe Electric Resistance Welded Pipe . ERW Galvanized Steel Tubes, ERW Galvanized Steel pipes welded erw hot steel pipeSteel Pipes manufacturers and Exports huge range of ERW Galvanized Steel Tubes & Steel Pipes . For pipes or tubes size 4 inch (10.2mm) OD and below, strip is fed into a set of forming rolls which consists of horizontal and vertical rollers so placed as to gradually from the flat strip in to a tube which is then allowed to pass the welding welded erw hot steel pipe ERW Steel Pipe & ERW Casing .

permanentsteelERW Steel Pipe and Tube, ERW Welded Pipe

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.
