Alloy Steel Studded Tube, ASME SA335 P5 with 11Cr, Fired Heater, Convective Heater Coils for oil refinary

Studded tubes are commonly used in heat exchangers and boilers. The studs on the outside of the tube increase the surface area, which improves heat transfer efficiency. This makes studded tubes useful in applications where heat exchange is critical, such as in industrial processes, power generation, and petrochemical plants.

In fired or steam heater, studded fin tubes are commonly used in the following parts:
1. Heater Coils: Studded fin tubes can be used in the heater coils to enhance heat transfer efficiency. The studs on the outer surface of the tubes increase the surface area available for heat exchange, leading to improved performance.
2. Combustion Chamber: Studded fin tubes can also be used in the combustion chamber of a heater to increase heat transfer rates and improve overall efficiency.
3. Radiant Section: In the radiant section of a heater, studded fin tubes can be employed to maximize heat transfer between the hot gases and the process fluid flowing inside the tubes.
4. Convection Section: Studded fin tubes can be used in the convection section of a heater to enhance heat transfer from the flue gases to the process fluid.
Overall, studded fin tubes play a crucial role in improving heat transfer efficiency and performance in various parts of a heater system.
