Alloy Steel HFW High Frequency Welded Solid Fin Tube ASME SA213 T5
T9 T11 T12 Boiler Condenser Heater Application
HFW Solid Finned Tubes short for High Frequency Welded Helical
Spiral Solid Finned Tube 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
type.
This welded steel finned tube configuration can be used for any
practically heat exchanger application, and is particularly suited
to high temperature and high pressure applications. The important
features of this configuration are efficient, effective bond of fin
to tube under all conditions of temperature and pressure, and
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.
Fin Tube Specification:
1. Add the heat exchange area and reduce the number of tubes, also
increase the fume flow section area to reduce the fume speed and
abrasion.
2. H type fin tube can be made to double H type fin tube, high
rigidness to fit long tube row.
3. H type fin economizer arranged in line to make the space into
many small zones, averaged air flow to reduce the abrasion.
4. With straight channel to gain the best ash-blowing effect.
5. The compact structure to reduce the weight and reduce the
manufacturing cost.
