ASTM A269 TP321 Heat Exchanger Tube for Heat Exchanger Condenser

ASTM A269 TP321 Heat Exchanger Tube , for Heat Exchanger , Condenser

ASTM A269 TP321 is a specification for seamless and welded stainless steel tubes primarily used for heat exchanger, condenser, and general instrumentation applications in environments where corrosion resistance, high strength, and durability are required.

Key Features and Advantages:

· Corrosion Resistance: Excellent resistance to oxidation and intergranular corrosion, especially in high-temperature environments.

· High-Temperature Strength: Maintains mechanical properties at elevated temperatures, making it ideal for heat exchanger applications.

· Stabilization with Titanium: Titanium addition prevents carbide precipitation, ensuring long service life even under thermal cycling.

· Good Weldability: TP321 can be welded using conventional methods without the risk of grain boundary carbide formation.

· Versatility: Suitable for both low- and high-temperature applications.

Chemical Composition:

Mechanical Properties:

Heat Treatment:

All TP321 tubes under ASTM A269 undergo heat treatment to ensure optimal mechanical properties and corrosion resistance. The typical heat treatment process is:

· Solution annealing at temperatures between 950–1150 °C (1742–2102 °F), followed by rapid cooling.

Common Applications:

· Heat Exchangers and Condensers: For corrosive fluid systems in chemical, petrochemical, and power plants.

· Oil and Gas Industry: For processing and refining equipment.

· Aerospace: For high-temperature exhaust systems.

· Food and Beverage: For sanitary tubing in processing equipment.

· Power Generation: For boilers, superheaters, and nuclear reactors.
