Description

Wound Fin Tube ASTM A249 TP321 For Air Cooler , Heat Exchager , Condenser

TP321 is a titanium-stabilized austenitic stainless steel that offers excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 427°C to 816°C (800°F to 1500°F). This alloy is particularly suitable for high-temperature applications and environments where oxidation and corrosion resistance are crucial.

When used in ASTM A249 TP321 Wound Fin Tubes, it becomes highly effective in heat exchanger applications, providing robust performance and efficient heat transfer. These fin tubes are widely used in power generation, industrial boilers, chemical processing, and aerospace industries, providing reliable and durable performance in demanding environments.

Key Features:

  • Enhanced Heat Transfer: The fins significantly increase the surface area, thereby enhancing the heat transfer rate.

  • Corrosion Resistance: TP321 provides excellent resistance to oxidation and intergranular corrosion, making it suitable for high-temperature applications.

  • Mechanical Bonding: The wound fin design ensures a secure mechanical bond between the fins and the base tube, ensuring efficient heat transfer and durability.

  • High Thermal Conductivity: Fins (often aluminum) ensure high thermal conductivity, improving overall heat exchanger efficiency.

  • Durable Base: The TP321 base tube provides high durability and resistance to mechanical stress under high temperatures.

Applications:

1. Heat Exchangers

  • Shell and Tube Heat Exchangers: Suitable for applications requiring efficient thermal transfer between two fluids, such as in chemical and petrochemical industries.
  • Air-Cooled Heat Exchangers: Ideal for systems where air is used to cool fluids, common in industrial and HVAC applications.

2. Boilers and Superheaters

  • Power Plants: Used in steam boilers and superheaters in power generation plants to transfer heat efficiently and withstand high pressures.
  • Industrial Boilers: Employed in various industrial boilers where high temperature and pressure conditions are common.

3. Chemical Processing

  • Chemical Plants: Used in heat exchangers and condensers in chemical processing plants due to its ability to handle high temperatures and corrosive environments.
  • Petrochemical Refineries: Utilized in refineries where high strength and resistance to corrosive substances are required.

4. Aerospace and Defense

  • Heat Exchangers: Employed in aerospace heat exchangers where materials must withstand high temperatures and corrosive environments.
