  • Difference between ERW and EFW Pipe

    ERW is the first letter abbreviation for electric resistance welding. ERW tube and submerged arc welding pipe significantly different, using a pressure free filler metal welding, the weld is not filled with other ingredients, relying on high frequency current skin effect and proximity effect, instantly heating the plate edge to welding temperature by squeezing rollers squeeze formed weld forging organizations.

  • ERW VS SAW Steel Pipes

    This is termed as Electric Resistance welded or ERW pipe or tubes. If this ERW is being drawn further to get desired size of tubes or pipes, in cold condition is called as Cold Drawn welded or CDW. SAW – Submerged Arc Welded Pipes or Tubes . This process is used for pipes or tubes from 24 ″ to 36 ″ i.e 610mm to 914mm OD. Flat plate is first pressed into U and later O shape.

  • ERW Pipe Electric Resistance Welded Nucor Skyline

    Electric Resistance Welded (ERW) pipe is manufactured by cold forming a flat steel strip into a rounded tube by passing it through a series of forming rollers to obtain a longitudinal seam. The two edges are then simultaneously heated with a high frequency current and squeezed together to produce a bond.
