Product Description

High Frequency Welded Fin Tube Product Description:

High Frequency Welded fin tube also called solid type fin tube,use steel or stainless steel strip directly welded to tube surface by HFW.Can improving heat transfer efficiency much more than bare tube.Due to the tight welding of the fins to the base tube, these finned tubes are often used in vibrating conditions.Fin type have Serrated fin and flat fin.

High Frequency Welded Fin Tube

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.

Spiral Welded Pipe

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

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

Fin Tube

High Frequency Welded Fin Tube(Spiral Welded Pipe) Applications

Spirally Wound High Frequency Resistance Welded Finned Tubes are used in Heat Recovery Systems associated with Furnaces for Petrochemicals applications, and with Boilers for Power Generation and Waste Heat Recovery applications. The usage of finned tubes in Heat Exchangers reduce cost and size of the equipment which directly results in performance improvement.
