The ASTM A312 TP304H Stainless Steel Serrated Fin Tube is a high-efficiency heat transfer component manufactured by attaching serrated stainless steel fins onto a TP304H seamless base tube through high-frequency welding (HFW). The serrated design significantly increases the surface area and enhances turbulence in gas flow, making it suitable for furnace tube convection sections where high-temperature and fouling resistance are critical.

High-Temperature Stability
TP304H is designed for elevated-temperature environments such as furnace convection zones.
Serrated Fin Efficiency
Serrated fins create micro-turbulence, enhancing heat transfer while reducing ash or soot buildup.
Corrosion & Oxidation Resistance
With excellent chromium and nickel content, TP304H resists oxidation and carburization in high-temperature gas streams.
Easy Maintenance
The serrated design helps reduce fouling and simplifies cleaning in harsh furnace atmospheres.
Primarily used in furnace tube convection sections in:
Refinery Process Heaters
Steam Reformers
Fired Heaters
Crude Oil Units
Waste Heat Recovery Units
Power Generation Furnaces
Position: Installed in the convection section of the furnace where flue gas flows across the finned tubes, transferring heat to internal fluids like steam, process oil, or feed gas.
