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
