  ERW pipes are manufactured from the longitudinal welding of steel. The welding process for ERW pipes is continuous as opposed to welding of distinct sections at intervals. ERW process uses steel coil as feedstock.

  The High Frequency Induction Technology (HFI) welding process is used for manufacturing ERW pipes. In this process the current to weld the pipe is applied by means of an induction coil around the tube. HFI is generally considered to be technically superior to “ordinary” ERW when manufacturing pipes for critical applications, such as for usage in the energy sector In addition to other uses in line pipe applications, as well as for casing and tubing.
