Serrated High-Frequency Welded Fin Tube
Serrated High-Frequency Welded Fin Tube
Our Serrated High-Frequency Welded Fin Tube combines excellent heat transfer performance with strong mechanical strength. We weld serrated fins directly onto the base tube through a high-frequency welding process, which creates a reliable bond and ensures efficient thermal conductivity.
Moreover, the serrated fin design increases airflow turbulence and improves heat exchange efficiency. As a result, the tube delivers better performance in high-temperature and demanding industrial environments.
We offer customized sizes, fin specifications, and material options, including carbon steel, stainless steel, and alloy steel. Therefore, customers can easily match the product to their specific application requirements.
Our High Frequency Welded Finned Tubes work widely in Heat Exchangers, Boilers, Economizers, Air Preheaters, and Waste Heat Recovery Systems. Furthermore, they help improve energy efficiency, reduce operating costs, and extend equipment service life.

Benefits of Serrated Fin Design
- The Serrated Fin Design improves heat transfer because it increases airflow turbulence and continuously disrupts the boundary layer. As a result, the system achieves higher thermal efficiency with the same heat exchange surface.
- In addition, this structure reduces fouling and keeps airflow more stable during long-term operation. Therefore, equipment runs more efficiently and requires less maintenance.
- Moreover, Serrated Fin Tubes help engineers improve performance without enlarging equipment size, so they reduce energy consumption and overall operating cost.
