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 HFW pipe High Frequency Welding pipe. What is ERW steel pipe? ERW steel pipe is manufactured through low or high frequency resistances Electric Resistance.
Welded pipe (pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp that are formed, bent and prepared for welding. The most popular process for large diameter pipe uses a longitudinal seam weld. Spiral welded pipe is an alternative process, spiral weld construction allows large diameter pipe to be produced from narrower plates or skelp.
