Product Description

L/LL/KL Finned Tube Product Description:

- L Finned Tube

The fin strip will be shaped in L form and tension wound to the base tubes outer surface. The L foot of the fin enhances the corrossion protection of the base tubes.

Max. working temperature: 150°C

Fin Materials: Aluminium and Copper

Base Tube Materials: No limits

- LL Finned Tube

Same way produced like L-TYPE but the fin foot is overlapping and covers the base tube outer surface which increases the corrossion protection of the base tube compared to the L-Type.

Max. working temperature: 180°C

Fin Materials: Aluminium and Copper

Base Tube Materials: No limits

- KL Finned TubeKnurled Aluminum Tubing

Produced same like L-TYPE but before application of fins the surface of base tube is knurled. The fin foot is knurled into the knurling to get a higher bond between tube and fins, resulting in better heat transfer parameters.

Max. working temperature: 260°C

Fin Materials: Aluminium and Copper

Base Tube Materials: No limits

L Finned Tube

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.

Aluminum Finned Tubes

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.

Knurled Aluminum Tube

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
