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.
