ASME SA213 T12 Alloy Steel HFW FIN TUBE For Waste Heat Recovery
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.
Specifications
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.
