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.

 

These Fin Tubes find application in RADIATORS, AIR PREHEATERS, WASTE HEAT RECOVERY SYSTEMS, & BOILER FIN TUBES etc and are preferred in Industries like Power Plants, Chemical Industries, Steel Plants, and Chiller Plants etc.

 

 

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

ASME SA213 T12 High Efficiency Welded Helical HFW Helical Spiral Serrated Finned Tube For Heat Exchanger Air Cooling
