ERW pipe manufacturing process includes HFW. ERW have low, medium, high frequency welding processes, and HFW is specially for high-frequency electric resistance welding. 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 ERW Pipe Electric Resistance WeldedElectric resistance welded (ERW) pipe is made from steel coil and the weld seam runs parallel to the pipe. The width of the coil is the same as the circumference of the pipe so diameters are limited to 24 inches. However, because the manufacturing process is fast, it is ideal for large production runs of small (<= 24 in.) diameter sections. ERW Straight Seam Welded Pipe - Permanent SteelERW straight seam welded pipe, also known as "resistance welded straight seam welded pipe", ERW straight seam welded pipe is mainly divided into two forms:ERW AC welded steel pipe and ERW DC welded steel pipe. ERW straight seam welded pipes are further divided into low frequency welding, intermediate frequency welding, ultra intermediate frequency welding and high frequency welding
