ASME SA210 Gr.A1 Seamless Tube with Aluminum Al1060 Embedded G type
Fin tube
Embedded fin tubes are used for heat transfer applications where
high efficiency in transferring heat is required. They have
extended surfaces in the form of fins that increase the surface
area available for heat transfer. These tubes are commonly used in
applications such as air coolers, heat exchangers, and boilers.

Applications:
The common application fields are:
1.Heat Exchangers: A179 Fin Tubes are commonly used in various
types of heat exchangers such as shell and tube heat exchangers,
air coolers, condensers, and other similar equipment. The fins on
the tubes increase the surface area available for heat transfer,
improving the efficiency of the heat exchange process.
2.HVAC Systems: These tubes are widely used in HVAC (Heating,
Ventilation, and Air Conditioning) systems for both heating and
cooling applications. The extended surface area provided by the
fins enhances the heat transfer capabilities of the tubes, making
them suitable for efficient temperature control in HVAC systems.
Boiler Systems: A179 Fin Tubes find applications in boiler systems
where they are used for heat transfer between the hot gases and
water to generate steam. The fins on the tubes help in maximizing
heat transfer efficiency, making them ideal for use in boilers for
power generation or other industrial processes.
3.Refrigeration Systems: In refrigeration systems, A179 Fin Tubes
are utilized for transferring heat from the refrigerant to the
surrounding environment or from one part of the system to another.
The fins on the tubes aid in improving the cooling efficiency of
the system.
4.Heat Recovery Systems: These tubes are also used in heat recovery
applications where waste heat generated during industrial processes
is captured and used for other purposes. The increased surface area
provided by the fins helps in maximizing heat recovery efficiency.
5.Process Industries: A179 Fin Tubes are employed in various
process industries such as chemical, petrochemical, and
pharmaceutical industries where efficient heat transfer is crucial
for maintaining optimal process conditions and product quality.
