Product Description
Specification of finned tube
Economy and Energy Saving
The high-fin tube is used to advantage when gases are to be heated or cooled or when a process stream is to be air-cooled. High-fin tubes come in a wide variety of fin heights, thickness, and spacings, giving values of Ao/Ai up to 25. For corrosion protection, a mechanically bonded liner tube may be used inside the finned tube. The liner can be made of corrosion-resistant alloy, while the outer tube and fins are made of a high conductivity metal such as copper or aluminum to improve heat transfer. One major application of high-finned tubes is in air-cooled heat exchangers. Atmospheric air, like all low pressure gases, gives a very low heat transfer coefficient at normal velocities. By contrast, the tube-side fluid, usually a liquid to be sensibly cooled or a vapor to be condensed may have a coefficient up to 100 times higher, or even more. Therefore, high-finned tubes are used in these exchangers to reduce to overall size of exchanger required.
