ASME SA179+Aluminum Embedded Finned Tube for Air Cooler/Heat Exchanger Application
Embedded finned tube is a type of heat exchanger that consists of a tube with an integral fin inside. The fin is embedded inside the tube wall and is generally made of a highly conductive material such as copper, aluminum, or stainless steel. The fins increase the surface area of the tube and provide a more efficient heat transfer by improving the heat transfer coefficient between the tube and the fluid. This design is commonly used in air-cooled heat exchangers and steam condensers. The embedded finned tube is considered more economical due to its higher efficiency and lower maintenance costs compared to other types of heat exchangers.
The characteristics of an embedded finned tube are as follows:
1. Increased surface area: Embedded fins increase the surface area of the tube, which results in a higher heat transfer area compared to other types of heat exchangers.
2. Higher heat transfer coefficient: The fins provide a higher heat transfer coefficient between the tube and the fluid, which improves the heat transfer efficiency.
3. More efficient: Embedded finned tubes are considered more efficient as they provide higher heat transfer rates with smaller temperature differences.
4. Reduced fouling: The fin design reduces the fouling of the tube surface, which reduces maintenance costs.
5. Durable: Embedded fins are generally made of highly conductive materials such as copper, aluminum, or stainless steel, making them durable and resistant to corrosion.
6. Cost-effective: Embedded finned tubes are generally considered cost-effective as they can transfer heat while minimizing the pressure drop across the system. They also have a longer lifespan, which reduces maintenance costs over time.

There are many different applications of embedded finned tubes, including:
1. Air-cooled heat exchangers: Embedded finned tubes are commonly used in air-cooled heat exchangers to increase efficiency and reduce temperature differences.
2. Steam condensers: The high heat transfer coefficients of embedded finned tubes make them ideal for use in steam condensers, where they can improve efficiency and reduce the size of the heat exchanger.
3. Heat Recovery Steam Generators: HRSGs are commonly used in power plants to recover waste heat from exhaust gases. Embedded finned tubes are often used in the heat recovery steam generators to maximize heat transfer efficiency.
4. Process heating and cooling: Embedded finned tubes can be used to heat or cool fluids in many different manufacturing processes, including chemical, petrochemical, and pharmaceutical manufacturing.
5. Refrigeration and air conditioning: The high efficiency of embedded finned tubes makes them ideal for use in refrigeration and air conditioning systems.
6. Oil and gas refining: Embedded finned tubes are often used in oil and gas refining processes, where they are used to cool or heat process fluids and refine crude oil.
