Aluminum Finned Tube for Heat Exchanger
SPECIALIST IN THE FIELD OF ALUMINUM FINNED TUBES
ALUMINUM FINNED TUBES IN VARIOUS TYPES
Aluminum finned tubes are offered in different variants. It is mainly important to look at the thermodynamic properties that the outside of a tube has. This determines to what extent additional surface is needed. You can also choose from a high or low finned on the aluminum finned tubes. A low finned tube is often chosen for oil-based coolers. Whereas in systems with air on the outside, a high finned tube is more likely to be chosen. A third factor is the choice between an L fins,an LL fins,an KL fins and a G fins.
Datang is your specialist in the field of aluminum finned tubes. These finned tubes have various applications and are used in heat exchangers, for example. Use the finned tube when the heat transfer coefficient on the outside of a tube is less than the same coefficient on the inside of it. The fins of a finned tube stimulate heat transfer, which enhances the effect of the heat exchanger. On this page you can read more about the use of the aluminum finned tubes that Datang offers you.

Aluminum Finned Tubes for Heat Exchanger
1.L-Foot Tension Wound Finned Tubes
Aluminum L-Foot Tension Wound Finned Tubes are an economical solution for applications requiring greater resistance to vibration and heat cycling typical of air cooled heat exchangers. The L-Foot design mechanically locks the fins and provides broader contact surface between tube and fin.
Below you will see common L-Foot Tension Wound Finned Tube configurations:
Tube Sizes: 1/2″ O.D. to 2″ O.D.
Fin Heights: 1/4″ to 5/8″
Fin Pitch: 4 to 13 fins per inch
Temperature: Up to 300°F
2.KL Fin Tube Edge Tension Wound Aluminum Finned Tubes
Edge Tension Wound Finned Tubes offer a low cost solution for low to moderate temperature applications. The surface of the tube is knurled as the fin is wound tightly on edge around the O.D. of a tube to ensure proper fin to tube contact.
Edge Tension Wound Finned Tubes are commonly used in applications with small amounts of vibration and metal temperatures up to 250° Fahrenheit.
Tube Sizes: 1/2″ O.D. to 2″ O.D.
Fin Heights: 1/4″ to 1″
Fin Pitch: 4 to 13 fins per inch
3.Embedded Aluminum Finned Tubes
Embedded Fin Tubes offer solutions where higher temperatures, continuous thermal cycling and tube vibration due to high velocity air streams can cause failures. The fin is mechanically embedded into a groove that is plowed in the tube O.D. and is locked into place by rolls that force the groove to tightly close around the fin base.
Tube Sizes: 9/16″ O.D. to 2″ O.D.
Fin Heights: 1/4″ to 5/8″
Fin Pitch: 5 to 13 fins per inch
4.Extruded Aluminum Fin Tubes
Extruded Finned Tubes provide the greatest resistance to atmospheric corrosion. The aluminum fin material completely encloses the tube, except at the ends where a tube coating can be applied. The fin is rolled from an outer aluminum tube by a process using pressure to create a rolled “pressure bond” between the liner tube and fins.
Extruded Finned Tubes are commonly used in applications with temperatures up to 550 degrees Fahrenheit.
Tube Sizes: 1″ O.D. to 1 1/4″ O.D.
Fin Heights: 1/2″ to 5/8″
Fin Pitch: 8 to 11 fins per inch
