High-frequency welded fin tubes, also called solid fin tubes, use steel strips or stainless steel strips to be directly welded to the surface of the pipe through high-frequency welding. Improves heat transfer efficiency compared to bare tubes. These finned tubes are often used under vibration conditions due to the tight welding of the fins to the base tube. Fin types include serrated fins and flat fins.
