Stainless Steel SA249 TP304 1.4301 Extruded Fin Tube Oil Cooler أنبوب الزعنفة
What is fin tube? أنبوب الزعنفة
Fin Tubes are the heart of air type heat exchangers/radiators (a kind of heat exchanger applied in hot air heating, drying, cooling or heumidifying). They are used for heat exchange in a variety of industries, such as food, electronics, petrochemical, texitle and pharmaceutical industries.
Extruded Finned Tube
This fin type is formed from a bi-metallic tube consisting of an aluminum outer tube and an inner tube of almost any material.
The fin is formed by rolling material from the outside of the exterior tube to produce an integral fin with excellent heat transfer properties and longevity.
Extruded fin offers excellent corrosion protection of the base tube and excludes virtually all exposure to any outside fluid.

The importance of fin profile:
The profile of the fins has significant effect of the performance of a finned tube heat exchanger. It is important to ensure each fin has a tight connection on the tube surface to provide maximum thermal conductivity.
The larger the fins and the tighter the fin pitch, the more thermal conductivity is achieved. The trade-off may be an increase in pressure drop which may, in turn, adversely affect performance. A balance between the two opposing functions is vital for effective and optimal thermal performance and equipment function.
Our Competitive Advantage:
1. We have more than 12,000 square meters workshop, including 12 finning machines, daily extrusion capacity up to 3,500 meters.
2. The finning machines of Integral Low Fin Tubes are designed and assembled by ourselves and we can offer you finning machines and all the parts of accessories etc...
3. The Integral Low Fins are rolled out of the tube surface to increase the tubes external surface area, without affecting any others dimension.
4. Low Fins are very useful for tight condensers and exhibits high efficiency of heat transfer.
5. Economical solutions of heat exchange problems of media with different heat conduction abilities or different current conditions.
6. High chemical-, thermal- and mechanical resistance, suitable for rough operation conditions.
Applications:
-Operating temperatures less than 300°C;
-Offshore or other remote applications;
-Heat pipes;
-Dry air coolers for air, gas or oil;
-Air to air heat exchangers for HVAC applications;
-Air dehumidification in air treatment plants and
