ASTM A376 TP347H Stainless Steel Fin Tube, Solid Fin Tube, For Heater and Economizer
The ASTM A376 TP347H Stainless Steel Solid Fin Tube is designed for use in heat exchangers, economizers, and heating systems. The tube is made from TP347H stainless steel, a high-temperature alloy that offers excellent oxidation resistance, creep strength, and mechanical stability under extreme conditions. The solid fins are welded onto the base tube, increasing the effective surface area for improved heat transfer in fired heaters and economizers.

Superior High-Temperature Strength
TP347H's niobium stabilization offers enhanced creep resistance in high-temperature environments such as economizers and furnaces.
Enhanced Heat Transfer
Solid fins increase the surface area significantly, improving the heat transfer rate between the fluid inside the tube and the surrounding environment.
Excellent Corrosion Resistance
TP347H provides excellent oxidation resistance, making it ideal for use in fired heaters, economizers, and superheaters exposed to high-temperature flue gases.
Durability
The solid fin design offers excellent mechanical stability under thermal cycling and high pressures typically seen in furnaces and boilers.
Weldability
The material is designed for easy welding and installation, making it suitable for complex furnace and economizer configurations.
The ASTM A376 TP347H Solid Fin Tube is used in heat transfer systems like:
Fired Heaters
Located in the convection zone where it absorbs heat from hot flue gases and transfers it to a working fluid.
Economizers
Heat recovery systems in power plants, helping to capture residual heat from exhaust gases and preheat feedwater for boilers.
Superheaters and Reheaters
In power plants, where steam generation efficiency is crucial.
Heat Recovery Steam Generators (HRSGs)
Recovering heat from flue gases in combined-cycle power plants.
