Embedded Finned Tube Carbon Steel ASTM A179 with AL1060 Fins For Heat Exchanger
ASTM A179 refers to a standard specification for seamless cold-drawn low-carbon steel tubes used in heat exchangers, condensers, and similar heat transfer applications. These tubes are known for their excellent thermal conductivity and mechanical properties.
When combined with AL1060 fins, the product becomes an embedded finned tube, which is a type of heat exchanger tube designed to enhance heat transfer efficiency. Here's a breakdown of the components:
ASTM A179 Tube:
Material: Low-carbon steel.
Properties: High thermal conductivity, good corrosion resistance, and excellent mechanical strength.
Application: Commonly used in heat exchangers, condensers, and boilers.
AL1060 Fins:
Material: Aluminum alloy 1060, which is a pure aluminum alloy (99.6% aluminum).
Properties: High thermal conductivity, excellent corrosion resistance, and lightweight.
Application: Fins are attached to the tube to increase the surface area for better heat transfer.
Embedded Finned Tubes:
- Construction: The fin strip is wound into a groove that is pre-cut on the tube surface. The fin is then secured into place by applying pressure through a rolling process, which locks the fin into the groove. The fins (AL1060) are embedded or bonded onto the outer surface of the ASTM A179 tube.
- Purpose: The fins increase the effective surface area of the tube, improving heat transfer efficiency in applications like air-cooled heat exchangers or condensers.
Key Features of ASTM A179 Embedded Finned Tubes with AL1060 Fins:
- High Heat Transfer Efficiency: The combination of steel tubes and aluminum fins maximizes heat exchange.
- Corrosion Resistance: AL1060 fins provide excellent resistance to corrosion, especially in harsh environments.
- Durability: ASTM A179 tubes offer mechanical strength, while the embedded fins ensure long-term performance.

Embedded finned tubes made of Carbon Steel ASTM A179 with aluminum 1060 fins can be efficiently used in a variety of heat exchanger applications. ASTM A179 specification covers seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus. Meanwhile, aluminum 1060 is a commercially pure aluminum with high corrosion resistance and excellent thermal conductivity.
Here are some typical applications for this type of embedded finned tube:
1. Air Coolers and Heaters:Given their high thermal efficiency and durability, these finned tubes are often used in air cooling and heating systems within industrial processes.
2. Condensers: The corrosion-resistant properties of aluminum finned tubes make them suitable for condensers in refrigeration systems or in power plants where they can condense steam into water.
3. Evaporators: Their high thermal transfer rates are advantageous in evaporators which are used in HVAC systems, refrigeration, and some industrial processes.
4. Heat Exchangers in HVAC Systems: The combination of carbon steel and aluminum fins is often used for heating, ventilation, and air conditioning systems where there is a need for efficient heat transfer without the requirement for high-pressure resistance.
5. Waste Heat Recovery Units: Industries that produce a significant amount of waste heat, like chemical plants or power generation facilities, use these finned tubes to reclaim heat that would otherwise be lost.
6. Petrochemical and Chemical Processes: In the petrochemical and chemical industries, these finned tubes might be used in heat exchangers to maintain the process temperatures for various chemical reactions.
