ASTM A106 GR.B Carbon Steel Seamless Pipe, Solid Fin tube, For Furnace Tube
The ASTM A106 Grade B Solid Fin Tube is manufactured using carbon steel seamless pipe with solid carbon steel fins integrally attached to the base tube, typically by high frequency welding (HFW). Designed for furnace convection sections, these finned tubes enhance heat transfer while withstanding the harsh thermal and mechanical conditions of fired heaters and industrial boilers.

Robust Construction
Seamless pipe base offers excellent strength and pressure resistance.
Solid Fin Efficiency
Increases the surface area for heat exchange without compromising mechanical integrity.
Cost-effective Material
Carbon steel offers strong thermal conductivity at an economical price.
High Welding Quality
High Frequency Welding ensures strong fin-to-tube bond, minimizing fin detachment.
Good Fabricability
Suitable for bending, coiling, and welding into complex furnace layouts.
These finned tubes are specifically suited for fired heaters and high-temperature heat exchangers, including:
Furnace Convection Sections
Petrochemical Refinery Heaters
Thermal Power Plant Boilers
Waste Heat Recovery Systems
Process Heater Banks
Installed typically in the upper convection section of furnaces, where flue gases are cooler and sustained heat recovery is essential.
