ASTM A179 ASME SA179 Finned Tube for Heat Exchanger
ASTM A179 and ASME SA179 are specifications for seamless cold drawn low carbon steel tubes used in heat exchangers， condensers， and similar applications. These tubes are widely used in various industries due to their excellent thermal conductivity and corrosion resistance.
Finned tubes， on the other hand， are tubes with extended surfaces or fins attached to enhance heat transfer. These fins increase the surface area of the tube， allowing for better heat transfer between the fluid inside the tube and the surrounding environment.
ASTM A179/ASME SA179 finned tubes are seamless tubes with fins attached to the outer surface. These fins can be either integral (welded or extruded) or external (wrapped around the tube). The fins can be made of various materials， such as aluminum， copper， or stainless steel， depending on the specific application requirements.
Finned tubes are commonly used in heat exchangers， air coolers， and other heat transfer equipment where efficient heat transfer is crucial. The finned design increases the heat transfer coefficient and improves overall system performance.
ASTM A179/ASME SA179 finned tubes are manufactured to meet specific dimensional and mechanical properties as per the respective standards. These tubes undergo various tests， such as hydrostatic testing， non-destructive testing， and dimensional inspection， to ensure their quality and reliability.
In summary， ASTM A179/ASME SA179 finned tubes are seamless low carbon steel tubes with fins attached to the outer surface. They are commonly used in heat exchangers and other heat transfer equipment to enhance heat transfer efficiency.

Manufacturing Process of ASTM A179 Finned Tube
Fin strips (usually aluminum and copper) are folded into an L shape and wound under tension on the surface of the base tube. The feet of the fins are connected together and cover the surface of the fins.
ASTM A179 Finned Tube is combined with two different materials
Core tube material: A179
Fin material: aluminum， copper， steel
1. Aluminum (Alu.1100， Alu.1060)
2. Copper.
3. Steel
Application
1. Heat exchangers: Finned tubes are widely used in heat exchangers to enhance heat transfer efficiency. The fins increase the surface area of the tube， allowing for better heat transfer between the fluid inside the tube and the surrounding environment.
2. Boilers: Finned tubes are used in boilers to improve heat transfer and increase the efficiency of the system. The fins help in transferring heat from the combustion gases to the water or steam inside the tubes.
3. Air coolers: Finned tubes are used in air coolers to transfer heat from the hot air to a cooling medium， such as water or air. The fins increase the surface area of the tube， allowing for efficient heat transfer.
4. Condensers: Finned tubes are used in condensers to transfer heat from the hot vapor to a cooling medium， such as water or air. The fins help in enhancing the heat transfer process and improving the overall efficiency of the condenser.
5. Oil coolers: Finned tubes are used in oil coolers to transfer heat from the hot oil to a cooling medium， such as water or air. The fins increase the heat transfer surface area， allowing for efficient cooling of the oil.
