Embedded G Type ASTM A213 T5 Fin Tube For Air Cooler , Condenser
Embedded G Type ASTM A213 T5 Fin Tubes are high-performance heat transfer components widely used in air coolers, condensers, and other heat exchanger systems. These tubes are manufactured using ASTM A213 T5 alloy steel, which offers excellent high-temperature strength and corrosion resistance. The "G type" fins are mechanically embedded into grooves on the base tube, ensuring a secure bond for efficient thermal performance and mechanical durability.
Key Features:
· Material Standard – ASTM A213 T5:
The base tube is made of ASTM A213 T5 alloy steel, a ferritic alloy containing chromium and molybdenum. This composition provides excellent resistance to high temperatures, oxidation, and corrosion, making it ideal for demanding heat exchanger applications.
· Embedded G Type Fin Design:
The fins are mechanically embedded into grooves cut into the surface of the base tube.
This design ensures a tight mechanical bond, allowing for efficient heat transfer while preventing fin detachment under thermal stress or vibration.
· Thermal Efficiency:
The fins significantly increase the surface area of the tube, enhancing heat exchange efficiency.
The embedded design ensures optimal heat conduction between the fins and the base tube.
· Durability and Mechanical Stability:
The mechanical embedding process ensures that the fins remain secure, even in high-pressure or high-temperature environments.
Resistant to thermal cycling, vibration, and mechanical wear.
· Corrosion and Oxidation Resistance:
ASTM A213 T5 alloy steel offers superior resistance to oxidation and scaling at elevated temperatures.
The tube can withstand harsh environments, including those with corrosive gases or fluids.
