What is EFW steel pipe - pipelinedubai

EFW pipe.ERW Electric Resistance Welded.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 electrodes.What is a Welded Steel Pipe? About Welded or ERW Steel Electric Resistance Welded (ERW) and High Frequency Induction (HFI) Welded Pipe,originally this type of pipe,which contains a solid phase butt weld,was produced using resistance heating to make the longitudinal weld (ERW).But most pipe mills now use high frequency induction heating (HFI) for better control and consistency.
