HFW Solid Finned Tube, High Frequency Welded Solid Finned

Helical Finned Tubes provide the designer with high thermal efficiency and compact design solutions for a whole range of heat exchangers where clean flue gases are used. Helical finned Tubes are manufactured in both Solid and Serrated types.

This welded steel finned tube configuration can be used for any practical heat exchanger application and is particularly suited to high-temperature and high-pressure applications.   The important features of this configuration are efficiency, the effective bond of the fin to tube under all conditions of temperature and pressure, and the ability to withstand high fin-side temperatures.

A continuous helical fin is attached to the base tube by high-frequency electric resistance welding in order to give an efficient and thermally reliable bond.
