  1. Electric Resistance Welded Pipe, ERW Steel Pipes, Electric ...

    High-frequency electric resistance welding (ERW) steel pipe production, internal weld surface treatments are generally incomplete curettage (left weld reinforcement) and complete curettage (scraping will form the inner surface of the groove) in two ways, and the results were not ideal, will affect the overall performance of the steel pipe.

  2. Electric Resistance Welded Tubing | Industrial Tube and Steel

    Electrical resistance welded tubes are produced from a hot rolled scale-free strip which is formed by rolls at room temperature into a tubular shape. Welding takes place as an electric current heats the two edges of the strip as they are pressed together.

  8. Electric resistance welding at a glance - The FABRICATOR

    Several electric resistance welding (ERW) processes are available for tube and pipe production. While each process has different characteristics, all ERW processes have one thing in common–all of them produce a forged weld.

  9. Electric resistance welding - Wikipedia

    Low-frequency electric resistance welding, LF-ERW, is an obsolete method of welding seams in oil and gas pipelines. It was phased out in the 1970s but as of 2015 some pipelines built with this method remained in service. Electric resistance welded (ERW) pipe is manufactured by cold-forming a sheet of steel into a cylindrical shape.

  10. Manufacturing Process - Standard Pipe - Steel Tube Institute

    Three principal processes—electric resistance welding, butt (continuous) welding and seamless—are used in the manufacture of Standard Pipe. The two welded processes begin with flat-rolled steel, the seamless process with steel billets. The process names are linked to an animated version of the manufacturing process.
