HFW Serrated Finned Tubes is short for High Frequency Welded Helical Spiral Serrated Finned Tubes.
Helical serrated finned tubes, serrated fins cut from a metal strip and then helically wound around the tubes.
The important features of this configuration are Efficiency, effective bond of fins to tubes under all conditions of temperature and pressure, and ability to withstand high fin side temperatures. This serrated fin configuration is even better to withstand the fin fouling if that is a problem in the application. This gives better heat transfer properties compared to solid fins.
