ERW/HFW Electric Resistance Welded Steel Pipe/Tube Overview of ERW/HFW Pipes. ERW pipe is the acronym for electrical resistance welded steel pipe, and HFW pipe represents high-frequency welding (HFW) steel pipe & tube. The pipes are made from steel coil and the weld seam runs parallel to the pipe. And it is one of the most versatile tools in agriculture, industry, and construction activities.
