Studded Fin Tubes

The nail head tube (studded fin tube) is also called nail like ribbed tube. In petrochemical industry, nail head pipe is widely used. Especially in the convection chamber of the tubular furnace, in order to enhance the heat transfer effect outside the tube, the heat transfer element often adopts the nail head tube.

Design Features

Studded Fins: The fins are attached to the outer surface of the tube, protruding outwards. This design increases the surface area available for heat transfer and promotes turbulent flow.

Material: Typically constructed from materials such as carbon steel, stainless steel, alloy or copper, providing durability and resistance to corrosion.

Robust Structure: These studs are arranged in a specific formation throughout the length of the tube. The studded design allows for effective heat transfer even in high-pressure applications.

This page let's talk about ASTM A213 T9 alloy studded fin tubes.

Details of ASTM A213 Base Tubes (Wall thickness generally is Min.)

ASTM A213 This specification covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes, designated Grades T5, T9, TP304, etc.

Advantages of Studded Fin Tubes

Because of the high welding speed and strong self cooling effect, the heat affected zone is small and oxidation is not easy to occur. Therefore, the microstructure and properties of the weld are very good;
The studded design significantly improves heat exchange efficiency compared to smooth tubes;
Corrosion resistance, wear resistance, low contact thermal resistance, high stability;
The studs disrupt fluid flow, leading to better mixing and improved thermal performance;
With a versatile application, suitable for a wide range of industries, including oil and gas, chemical processing, and power generation;
The robust construction makes them suitable for harsh operating conditions, including high temperatures and pressures.

Application

Heat exchangers, boilers, furnaces and refineries
Widely used in industrial heat exchangers for power generation, petrochemical processes, and HVAC systems.

Cooling systems
Common in cooling towers, condensers, and evaporators, where efficient heat dissipation is essential.

Fired Heaters
Employed in fired heaters and other thermal process equipment to enhance heat transfer efficiency.

Marine Applications
Used in ship cooling systems and other marine heat exchangers where robust performance is required.
