ASTM A312 TP304H is a high-carbon version of 304 stainless steel, offering superior strength and corrosion resistance at elevated temperatures.
This material is ideal for high-temperature applications such as furnaces, boilers, and heat exchangers, where high mechanical strength and resistance to oxidation are crucial.
304H stainless steel also provides excellent weldability, formability, and corrosion resistance, making it a reliable material for convection coils and heat exchangers.
The serrated fin design involves sharp-edged fins that create turbulence in the airflow, which improves heat dissipation from the base tube.
The serrated edges increase the surface area for heat exchange, allowing for more efficient heat transfer between the fluid inside the tube and the surrounding air.
This design is particularly effective in convection coils, air-cooled heat exchangers, and cooling systems where enhanced thermal performance is needed.
The fins are made of SS304 stainless steel, which offers excellent corrosion resistance and high-temperature stability.
SS304 is highly resistant to oxidation, corrosion, and stress corrosion cracking, making it ideal for high-temperature and high-pressure environments such as furnaces and power plants.
The HFW serrated fin tube is designed for convection coils in furnaces, heat exchangers, and boilers where efficient heat transfer is critical in high-temperature and high-pressure systems.
The serrated fin design improves heat dissipation from the hot gases to the cooling medium (liquid or air), making it ideal for use in industrial heating systems, power plants, and petrochemical applications.
