The ASME SA312 TP347 Stainless Steel HFW Serrated Tube with Stainless Fin Strip is a high-performance heat transfer solution designed for use in economizer applications. The tube is made from TP347 stainless steel, which provides excellent resistance to high-temperature oxidation and corrosion, making it ideal for use in economizers and other high-temperature heat recovery systems. The serrated fin design enhances the thermal performance by increasing the surface area for heat exchange, making it perfect for use in power plants, furnaces, and boilers that require efficient heat recovery from exhaust gases.
TP347 stainless steel is a high-alloy austenitic steel that contains columbium and tantalum, making it highly resistant to high-temperature oxidation and intergranular corrosion.
TP347 offers excellent resistance to sulfur compounds, which is crucial for use in economizers where the tube is exposed to high-temperature flue gases.
This material provides superior strength at elevated temperatures, making it ideal for use in heat recovery systems and economizers that operate under high-heat and pressure conditions.
The serrated fin design maximizes heat transfer efficiency by increasing the surface area for heat exchange and inducing turbulence in the surrounding fluid or gas.
The serrated edges of the fins break up the boundary layer of fluid, improving contact efficiency and allowing more effective heat dissipation, which is essential in applications like economizers where efficient heat recovery is necessary.
The fins are made from stainless steel, which ensures excellent corrosion resistance, particularly in high-temperature environments and chemical-rich gases such as those encountered in economizers, furnaces, and boilers.
Stainless steel fins also offer strength and durability, maintaining their performance even under thermal cycling conditions, which are typical in economizer applications.
ASME SA312 TP347 Stainless Steel HFW Serrated Tubes are designed for economizers, where they help recover heat from exhaust gases in power plants, boilers, and furnaces.
These tubes are particularly useful in energy recovery systems, where their high heat transfer and corrosion resistance make them ideal for heat exchange in high-temperature systems.
