LL-Fin Tube
LL-Fin Tube is manufactured in the same way as the "L" finned tube type except that the fin foot is overlapped to completely enclose the base tube thereby giving excellent corrosion resistance. This type of finned tube is often used as an alternative to the more expensive extruded type fin in corrosive environments.
*Maximum working temperature: 180 deg C.
*Atmospheric corrosion resistance: Acceptable
*Mechanical resistance: Poor
*Fin materials: Aluminum, Copper
*Tube materials: Any theoretical limit
