Products Description
Aluminum Extruded Finned Tubes And Tubing
Advantages of Aluminum Extruded Finned Tubes And Tubing
- Aluminum has good thermal conductivity and high heat transfer efficiency. Compared with copper or steel finned tubes, it is lightweight, which can reduce structural loads and installation costs, and is suitable for air-cooled heat exchangers in power plants and petrochemical plants.
- 3003 material features strong resistance to salt spray and marine atmosphere, suitable for offshore and ship cooling systems.
- Corrosion-resistant aluminum alloys can withstand outdoor exposure, and efficient heat transfer improves the performance of heat recovery and storage, and can be used in renewable energy systems such as solar thermal energy and biomass energy.
Applications of Aluminum Extruded Finned Tubes And Tubing
- Air-cooled heat exchangers (ACHE): power plants, petrochemical plants, compressor stations, etc.
- HVAC systems: chillers and condensers, evaporator coils, air heaters and reheaters, etc.
- Offshore and marine applications: marine engine cooling systems, marine HVAC systems, offshore platform air coolers, etc.
- Renewable energy systems: biomass boilers, geothermal recovery, solar thermal systems, etc.
- Food and chemicals: dryers, air heaters, etc.

Possible Alternative Grades
| Alternative Grade | Main Feature | Used When |
| AA 1050 / 1060 | High thermal conductivity, soft temper | For maximum heat transfer efficiency |
| AA 1350 | High electrical conductivity | When electrical and thermal transfer is needed |
| Copper (C12200) | Excellent conductivity, higher cost | When corrosion is not a primary concern |
| Carbon Steel (A179) | High strength, low cost | When weight and corrosion are less critical |
Packaging
Once the pipes have passed all inspections and tests, they are ready for packaging. They are usually packaged in bales wrapped in plastic. The pipes can be bundled and ready for delivery according to customer requirements, ensuring that the pipes are protected during transportation and prevent surface damage.
