and high-temperature environments.
Key Features1. Base Tube Material: ASTM A312 TP304H Stainless SteelASTM A312 TP304H is a high-carbon version of SS304 stainless steel, known for its enhanced mechanical properties at high temperatures. It provides excellent resistance to oxidation and corrosion, especially in high-temperature environments, making it ideal for use in convection coils, boilers, heat exchangers, and other high-performance heat transfer systems. 304H stainless steel also ensures long-term reliability in furnaces and energy recovery systems, where both strength and thermal stability are crucial.
2. Fin Type: Serrated Fin DesignThe serrated fin design enhances heat transfer by creating turbulence in the surrounding air or fluid, reducing the thermal boundary layer and increasing the efficiency of heat dissipation. This design significantly increases the surface area for heat exchange while reducing airflow resistance, making it ideal for use in convection coils and cooling systems that require efficient heat exchange in compact spaces.
3. Fin Material: SS304 Stainless SteelThe SS304 stainless steel fins are highly resistant to corrosion and oxidation, providing durability and long service life in environments exposed to moisture, high-temperature steam, and flue gases. SS304 is also highly resistant to stress corrosion cracking, which is essential for convection coils in high-temperature, high-pressure systems such as furnaces and heat exchangers.
4. Application: Convection Coils, Heat Exchanger, Boiler, FurnaceThe HFW serrated fin tube is ideal for convection coils in furnaces, boilers, and heat exchangers, where efficient heat transfer and reliable performance are required under high-temperature and high-pressure conditions. The serrated fin design ensures that the tube performs effectively in industrial heating systems, power generation, and energy recovery applications, where maximizing heat dissipation and thermal efficiency is essential.
