ASTM A312 TP304H Stainless Steel Seamless Pipe, Serrated Fin Tube, For Convection Coil
ASTM A312 TP304H Serrated Fin Tube is manufactured using high-temperature grade austenitic stainless steel TP304H as the base tube. Serrated stainless steel fins are high-frequency welded (HFW) onto the tube to enhance heat transfer. This finned tube is ideal for convection coils in industrial furnaces, reformers, and heaters, where higher thermal efficiency and fouling resistance are required.

Serrated Fin Design
Breaks boundary layer and enhances heat transfer by increasing turbulence in gas flow.
High-Temperature Strength
The higher carbon content in TP304H improves creep resistance and stability at elevated temperatures.
Excellent Corrosion Resistance
Withstands acidic and oxidizing environments, making it suitable for harsh furnace exhausts.
Improved Fouling Resistance
Serrated fins reduce dust accumulation, minimizing maintenance downtime.
Longer Service Life
Durable under continuous thermal cycling in demanding refinery and petrochemical processes.
Commonly used in convection sections of:
Process Heaters
Steam Reformers
Petrochemical Furnaces
Hydrocarbon Processing Units
Heater Convection Coils in Refineries
Typically installed in the convection zone of fired heaters, where hot flue gas transfers residual heat to process fluids before exiting the system.
