L/LL/KL Finned Tube Product Description:
- LL Finned Tube(OR OVERLAPPED FIN)
The fin is wrapped around the tube with an overlapping foot and secured at each end. It offers excellent corrosion resistance and is often used as an alternative for expensive extruded fins in corrosive environments.
Upper Temperature limit: 180°C
Tube Material: Any standard material we stock or is requested
Fin Material : Aluminium or Copper
- KL Finned Tube(Knurled Aluminum Tubing)
The KL finned tube is manufactured like the ‘L fin’ only the fin is wrapped around the tube and the foot is rolled into the outer surface of the preknurled tube. KL finned tubes give good surface protection to the tube and improve heat transfer.
Upper Temperature limit: 250°C
Tube Material: Any standard material we stock or is requested
Fin Material : Aluminium or Copper
- L Finned Tube(OR WRAPPED FIN)
The Extruded Fin Tube is wrapped around the tube and secured at each end to provide some surface protection. L Fin tubes are renowned for maximum heat transfer and enhanced corrosion protection - suiting moderate temperature cooling applications.
Upper temperature limit: 120°C
Tube Material: Any standard material we stock or is requested
Fin Material : Aluminium or Copper
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:
- L Finned Tube
Suitable for low-temperature application.
The finning type is the most cost effective method compared to the others.
The failed fins can be easily removed during production and bare tube can be used again for finning.
There is no need for make a helical grove over the core tube.
It is possible to place the fins on a very thin-walled tube with is particularly desirable when using expensive alloys as core tube.
The tube can withstand a temperature of up to 130°C without the risk of atmospheric corrosion or thermal stress.
- LL Finned Tube
This type of finned tube is often used as an alternative to the more expensive extruded type fin in corrosive environments.
Maximum operating temperature 170ºC.
- KL Finned Tube
Corrosion-resistant Tubes
Vibration resistance
It can withstand temperatures of up to 320°C (608°F).
High thermal performance and stress resistance combined with protection from air corrosion is a one-of-a-kind combo.
Any form of finned tube can be replaced with KL.
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
