High Frequency Welding Fin Tube (HFW Fin Tube), also called solid type fin tube, uses steel or stainless steel strip or steel round bar directly welded on the pipe/tube surface. This type of fin tube significantly improves heat transfer efficiency compared to bare tubes. Due to the tight welding of fins to the base pipe/tube, these finned tubes are ideal for vibrating conditions.
