High Frequency Welded Fin Tube (Continuously Welded Spiral Fin Tube):
As the name suggests， in this type of Fin Tube the finning is a Spirally Wound.
The fins are manufactured by Spirally Winding the fin around the Base Tube and Pipe. During the winding the fin is Continuously Welded by High Frequency welding giving the Most robust bond between the the Fin and the Tube.
This type of Fin Tube is used specifically where the application involves a lot of Mechanical Stresses like continuous vibrations etc.
The welding bond between the Tube and The Fin also ensures that almost perfect heat Transfer Efficiency is achieved. Also it can give the highest operating temperature ranges.
High Frequency Welded Fin Tube (Continuously Welded Spiral Fin Tube):
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
