Embedded Finned Tube ASTM A179 with AL1060 Fins For Air Coolers and
Condensers
An Embedded Finned Tube ASTM A179 with Aluminum 1060 Fins is a
specialized heat exchanger component designed to enhance heat
transfer efficiency. It consists of a base tube made of ASTM A179
carbon steel and fins made of Aluminum 1060, which are embedded
into the tube's surface. This combination leverages the strengths
of both materials to provide high thermal performance, durability,
and corrosion resistance.
Key Components:
1. Base Tube (ASTM A179):
Material: Low-carbon steel.
Properties: High thermal conductivity, excellent mechanical
strength, and good pressure resistance.
Applications: Suitable for high-temperature and high-pressure
environments.
2. Fins (Aluminum 1060):
Material: Pure aluminum alloy (99.6% aluminum).
Properties: High thermal conductivity, lightweight, excellent
corrosion resistance, and good formability.
Applications: Ideal for enhancing heat transfer in air or gas
environments.
3. Embedded Fin Design:
The fins are mechanically embedded into the outer surface of the
tube, creating a strong bond between the tube and fins.
This design ensures efficient heat transfer from the tube to the
fins and then to the surrounding medium (e.g., air or gas).
The base tube carries the primary fluid (liquid or gas) that needs
to be heated or cooled.
The aluminum fins increase the surface area of the tube, allowing
for more effective heat exchange with the secondary medium (usually
air or gas).
Heat is transferred from the tube to the fins and then dissipated
into the surrounding environment.
Key Features:
- High Thermal Efficiency: The combination of carbon steel and
aluminum maximizes heat transfer rates.
- Corrosion Resistance: Aluminum fins provide excellent resistance to
corrosion, especially in moist or chemically aggressive
environments.
- Lightweight: Aluminum fins reduce the overall weight of the heat
exchanger.
- Durable: The embedded fin design ensures a strong mechanical bond,
preventing fin loosening over time.
- Cost-Effective: Offers a balance between performance and cost
compared to all-aluminum or all-copper finned tubes.
