ERW pipe Electric Resistance Welded Pipe HFW pipe High Frequency Welding pipeDifferences between ERW Steel Pipe and HFW Steel PipeCarbon Steel Pipe - an overview ScienceDirect Topics

ERW pipe is made from coils that are cupped longitudinally by forming rolls and a thin-pass section of rolls that brings the ends of the coil together to form a cylinder. The ends pass through a high-frequency welder that heats the steel to 2600 °F and squeezes the ends together to form a fusion weld.Carbon Steel Tube Mill Machine or Machine ERW High frequency welded carbon steel pipes tube - ERW Pipe MillHome Products ERW Pipe Mill Carbon Steel Tube Mill Machine or Machine Unit for High-frequency Straight Seam Welded Pipe.
