High Frequency Welded Fin Tube Product Description:
Fin Tube with welded on fins are used in numerous industrial applications. The finned tubes will be supplied according to customers special requirements and/or specifications. The fins will be welded to tube either HF method or with filler metal added. The finned tubes will be supplied either as solid fins or serrated fins as per your demand.
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
Fin To Tube Bond:- Excellent
Heat Transfer Efficiency:- Excellent
Mechanical Resistance:- Excellent (Hence can be frequently cleaned with high pressure jets unlike other fin tubes. Thereby reducing down time and increasing overall life)
Corrosion Protection:- Moderate
Temperature Range:- Up to Maximum 500 Deg C
High Frequency Welded Fin Tube(Spiral Welded Pipe) Applications：
The High Frequency Welded Solid Fin Tube have been widely used in heat recovery of boiler economizers, air preheaters and waste heat boilers, as well as heat exchangers in various fields such as chemical and pressure vessels.
