High Frequency Welded Fin Tube Product Description:
The important features of this configuration are efficient, effective bond of fin to tube under all conditions of temperature and pressure, and ability to withstand high fin side temperatures. This solid fin configuration is the most rugged and will stand up to repeated cleanings for fin fouling if that is a problem in the application.
High Frequency Finned Tube Manufacturing Process:
The High Frequency Resistance Welding process usually employs 400, 000 Hz current. With this technique, the fin is wound on edge around the tube spirally and a continuous weld is obtained.
The High Frequency Resistance Welding process produces a strong metallurgical bond between the fin and the tube while minimizing the heat affected zone (HAZ) in the tube.
High Frequency Welded Fin Tube(Electric Resistance Welded Pipe) Advantages:
1. Higher heat transfer coefficient. The serrate can make the gas flow across the fins freely, enhancing the turbulent motion and improving the heat transfer effect. Researches show that serrated fin tube’s heat transfer efficiency is about 15-20% higher than common solid fin tube.
2. Reduce metal consume. Due to the higher heat transfer coefficient, for the same amount of heat, serrated fin tube is with less heat transfer areas, which help reduce the metal consume.
3. Anti-ash-deposition and anti-scaling. Due to the serrate, it is very hard for the serrated fin tube to deposit the ash and scaling.
4. It is more flexible to adapt to the changes of gas flow direction.
High Frequency Welded Fin Tube(Welded Aluminum Pipe) Properties:
Manufacturing Process:- Continuously Welded Spiral Fin Tube
