LL - Foot Tension Wound Finned Tube

Kasera Fin Tube offers LL-Foot Tension Wound Finned Tubes. Manufactured in the same way as the 'L' fin type except that the fin foot is overlapped to completely enclose the base tube thereby giving excellent corrosion resistance. This type of tube is often used as an alternative to the more expensive extruded type fin in corrosive environments. If say in simply- Aluminium fin strip is formed to LL shape and tension wound on the tube with overlapping of fins as shown in the figure.
