Laser Welded Finned Tubes
A high-quality type of heat exchanger component
Professional Laser Welded Finned Tubes Manufacturer
Cufin Tube specializes in manufacturing a wide range of laser welded finned tubes. A type of heat exchanger component that enhances heat transfer efficiency through a strong, precise bond between the tube and fin. Laser welded finned tubes maximize heat transfer by creating a strong, thermally conductive pathway from the tube to the fins, significantly increasing the surface area available for heat exchange, and promoting turbulence. The thermal performance of welded finned tubes was to be three times higher than that of plain tubes.
Technical Specification:
- Fin height of the fin is more than 5mm;
- Heat transfer surface area is more than 7 times of the plain tube;
- Fin density: 5 fins/inch; 7 fins/inch; 8 fins/inch; 9 fins/inch.
- Outer diameter is 30-60mm;
- Fin height: 5-15mm;
- Maximum processing length: 7m.

What Is Laser Welded Finned Tubes?
Laser welded finned tubes are heat exchanger components designed to maximize heat transfer efficiency by utilizing laser welding to join fins to a base tube. The laser welding process creates a strong and durable bond with a high welding penetration rate. This allows for a higher fin density and a more uniform fin-to-tube bond, enhancing heat transfer and reducing the risk of fin damage. The process is precise, resulting in minimal heat-affected zones and reduced thermal distortion.
Improved Heat Transfer: The strong, gap-free bond between the fin and the tube minimizes thermal resistance, leading to more efficient heat transfer.
Enhanced Durability: The precise and controlled welding process results in a strong and durable bond, improving the long-term reliability of the finned tube.
Versatility: Allows for the use of various material combinations to optimize performance in specific applications.
Compact Design: Enables the creation of more compact and efficient heat exchangers.
Advantages Of Cufin Tube's Laser Welded Finned Tubes
Strong and Durable Bond: Laser welding creates a robust and lasting connection between the fin and the tube, ensuring reliable performance over time.
High Fin Density: More fins can be packed onto the tube surface, increasing the heat transfer area.
Uniform Fin-to-Tube Bond: Improves heat transfer and reduces the chance of fin damage or detachment.
Precise Control: Laser welding allows for accurate control over the welding process, resulting in consistent and uniform welds.
Lower Heat Input: Reduces the risk of distortion in the base tube and fins.
