3. Definition of Extruded Finned Tube 

O extruded finned tube is comprised of aluminum fins that have been extruded onto a base tube. Since extreme pressure is used in the extrusion process, aluminum creates a seamless outer sleeve. Fins then protrude from the sleeve itself.

Due to the integrally formed fins, there is excellent mechanical strength. This ensures that the fins will not loosen with use. In addition, vibration doesn’t shorten the lifespan of the product.

4. How Extruded Fin Tubes Operate

Hot fluid is contained within the interior of the base tube. Cool air passes over the fins on the outside of the tube. Heat is then able to travel through the tube wall. Afterward, the fins provide larger surface area for external heat transfer. Therefore, the end result is a more efficient system.

Since aluminum sleeves cover the base tube, corrosion is minimized.

5. Features & Components

5.1. Base tube

Carbon steel stainless steel or copper materials are available. It transports the process fluid.

5.2. Aluminum sleeve

The thick aluminum layer is formed by extrusion. The aluminum layer improves heat transfer efficiency.

5.3. Integral fins

The fins are built integral to the sleeve. Thus, they allow optimal mechanical strength.

Resulting in a sturdy extruded finned tube design.

6. Benefits

It offers superior heat conductivity. Also there is no risk of fins popping off due to the integral design. The aluminum layer provides corrosion resistance to the elements.

The sturdy design prevents damage from impact. This makes them ideal for rugged environments. Many power plants and refineries use extruded finned tubes for this reason.

Other advantages include:

• Long lasting
• Highly mechanically stable
• Excellent vibration resistance
• Low lifetime cost
• Increased efficiency of heat transfer
• Ideal for outdoor usage

7. Comparison to Other Finned Tubes

7.1 Extruded vs L-Foot Finned Tube

The L-foot fins are mechanically attached to the tube. On the other hand, extrusion forms a mechanical bond. This is why extruded finned tubes are more durable.

7.2 Extruded vs Welded Finned Tube

Welded fins are ideal for high temperature applications. On the other hand, corrosion resistance is improved with extruded finned tubes.

7.3 Extruded vs Embedded Finned Tube

Embedded fins rest within grooves. Extruded fins cover the tube in a solid sleeve. This is why extruded finned tubes have more structural integrity.
