L/LL/KL Finned Tube Product Description:
- LL Finned Tube
LL fin tubeSame as L fin except the fin foot is overlapped giving more corrosion protection. Also named Over Lapped Fin Tube. The fin is helically wound around the base tube forming a strong mechanical contact between the tube and fin, thus improving the heat transfer efficiency.This type of finned tube is often used as an alternative to the more expensive extruded type fin in corrosive environments.
Maxumum working temperature:330 F (165 ℃)
Application:
Air Cooler,Charge Air Chiller, Condenser,Evaporator, Fluid Cooler, Gas Cooler,Oil Cooler, Radiator, Refrigeration,Steam to Air Heat Exchanger etc.
- KL Finned Tube（Knurled Aluminum Tubing）
KL type fin tube same as L fin tube,except that the base tube is knurled before application of the fin foot.Also named Wrap On Knurled type fin tube.After application,the fin foot is knurled into the corresponding knurling on the base tube thereby enhancing the bond between fin and tube,Resulting in improved heat transfer efficiency.
The fin is helically wound around the base tube forming a strong mechanical contact between the tube and fin,thus improving the heat transfer efficiency.This also give considerable corrosion protection to the base tube.
Maxumum working temperature:500 F (260 C)
Application:
Air Cooler fins,Charge Air Chiller, Condenser,Evaporator, Fluid Cooler, Gas Cooler,Oil Cooler, Radiator, Refrigeration,Steam to Air Heat Exchanger etc.

Maxumum working temperature: 270 F (130 C)
Application:
Air Cooler,Charge Air Chiller, Condenser,Evaporator, Fluid Cooler, Gas Cooler,Oil Cooler, Radiator, Refrigeration,Steam to Air Heat Exchanger,superheater etc.
L/LL/KL Finned Tube(Knurled Aluminum Tube) Manufacturing Process:
Applied Fin Tube is made with strip wrapped under tension around the base of the tube. Fins are welded to the base tube at the strip ends.
L/LL/KL Finned Tube(Aluminum Finned Tubes) Advantages:
Core tube extensively protected against corrosion by the fin foot, finning of very thin-walled tubes possible.
L/LL/KL Finned Tube Properties:
Atmospheric Corrosion Resistance: OK
Mechanical Resistance: Poor
Fin Contact: Interference Fit
Fin To Tube Bond :Moderate
Heat Transfer Efficiency :Moderate
L/LL/KL Finned Tube Applications：
. the petroleum, chemical and petrochemical process industries
. natural gas treatment
. the steel industry: blast furnace and converter systems
. power generation: steam turbine exhaust condensing
- contact condensing with cooling of circulating condensate
- fossil and nuclear power plants
. air conditioning (Freon, ammonia, propane)
. incineration of household refuse
. compressor coolers, etc.
