Lord Fin Tube- Extruded Bimetallic Finned Tubes

The extruded bimetallic finned tubes manufactured by T.S. Industrial Co.,Ltd have definite advantages in regard to thermal stability and mechanical durability that is a direct result of using a bimetallic extrusion process. In addition, application of the bimetallic extrusion provides efficient protection against corrosion caused by the weather and thereby guarantees long-term operation under harsh weather conditions.

Due to greater stiffness finned tubes can be easily cleaned with vapour or water without any risk of bending or damaging the fins. Any metal tube withstanding the load during the finning process is suitable for use as an inner tube. The special features of the extruded finned tubes allow operation at temperature as high as 300 ºC (572 ºF).

High-fin 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.

Bimetallic finned tubes common application fileds are:

1. Heat exchangers units for power plant(electric, nuclear, thermal and geothermal power plants);

2. High corrosive systems (condensers, evaporators, sea water desalinations, fertilizing, urea systems, ammonia, gas, corrosive acids);

3. The petroleum, chemical and petrochemical industries;

4. The food processing and refrigeration industries;

5. Natural gas treatment.
