ASTM B163 INCOLOY 825 FIN TUBE With Aluminum Fin For Boiler
ASTM B163 is the standard specification for seamless nickel and nickel alloy condenser and heat-exchanger tubes. It covers various grades of nickel and nickel alloy tubes, including Incoloy 825.
Incoloy 825 is a nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium. It offers excellent corrosion resistance in various environments, including highly oxidizing and reducing conditions. Incoloy 825 is commonly used in applications such as chemical processing, oil and gas, and marine environments.
A fin tube with aluminum fins is a type of heat exchanger tube that has aluminum fins attached to its outer surface. The fins increase the surface area of the tube, allowing for enhanced heat transfer efficiency. Aluminum is commonly used for the fins due to its high thermal conductivity and lightweight properties.
When used in boilers, ASTM B163 Incoloy 825 fin tubes with aluminum fins provide efficient heat transfer and corrosion resistance. The combination of Incoloy 825's corrosion resistance and aluminum's thermal conductivity makes it suitable for high-temperature and corrosive environments typically encountered in boiler applications.
