ERW PIPE
Electric Resistance Welded (ERW)
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. However, the product is still often referred to as ERW
pipe, even though the weld may have been produced by the HFI process.
