ASME SA210 Gr.A1 Seamless Tube with Aluminum Al1060 Embedded G type Fin tube
Embedded fin tubes, also known as finned tubes or finned pipes, are specialized heat transfer components used in various industries and applications. They consist of a base tube with external fins that are tightly embedded or integrally welded onto the tube surface. The fins increase the surface area of the tube, enhancing heat transfer efficiency.
The primary purpose of embedded fin tubes is to improve heat exchange between a fluid flowing through the tube and the surrounding environment or another fluid. The design and construction of the fins significantly enhance heat transfer rates by increasing the available surface area for heat transfer.

Applications:
The common application fields are:
1.Heat Exchangers: A179 fin tubes are widely used in heat exchangers, particularly in applications where low-carbon steel is compatible with the working fluids involved. They are utilized in both air-to-fluid and fluid-to-fluid heat exchangers, facilitating efficient heat transfer between different mediums.
2.HVAC Systems: A179 fin tubes are employed in heating, ventilation, and air conditioning (HVAC) systems for effective heat transfer. They are used in air handling units, air coolers, and other components where heat exchange between air and a fluid (such as chilled water or refrigerant) is required.
3.Industrial Boilers: A179 fin tubes find application in industrial boilers, including steam boilers and hot water boilers. They enhance heat transfer from flue gases to water, improving boiler efficiency and optimizing energy utilization.
4.Economizers: A179 fin tubes are commonly used in economizers, which are heat exchangers that recover waste heat from flue gases in power plants, industrial furnaces, and other combustion systems. The finned tubes maximize heat transfer and help preheat the feedwater, improving overall system efficiency.
5.Condensers: A179 fin tubes are utilized in condenser units where heat is transferred from a hot vapor to a cooling medium, causing the vapor to condense. They are commonly employed in refrigeration systems, air conditioning units, and power plants.
6.Oil Coolers: A179 fin tubes are suitable for oil cooling applications, such as in hydraulic systems or lubrication systems. The fins increase the surface area, allowing efficient heat dissipation and maintaining optimal oil temperature.
7.Heat Recovery Systems: A179 fin tubes play a crucial role in heat recovery applications, capturing waste heat from various industrial processes and transferring it to a medium for further use. They are used in systems that aim to improve energy efficiency and reduce operational costs.
