Embedded Fin tubes or names as G type Finned tube
The Embedded Fin tubes main design involves the fin inserted and welded into a helical groove cut into the tubes. They can be used in higher temperatures, and are very durable. Embedded fins are best suited for the usages that involve high thermal cycling or high temperatures and where the finside will be subjected to regular cleaning.
Common Applications: Air Cooled Heat Exchangers, Steam Coils, Air Preheaters.
Max. Working Temperature: 400 °C
Atmospheric Corrorsion Resisitance: OK
Mechanical Resistance: Poor
Fin Material: Copper, Aluminum
Base Tube materials: Any material available, such as Carbon steel Tube, A179, A192, A210, stainless tube A269/A213 T5 T11 T22 304 316
The Tension Wound Fin means the fins wrapped tightly around the tube and welded or stapled at the ends of tubes to hold the form. Tension Wound Fins can also be solder-coated to strength the corrosion resistance. Tension wound fin works especially prefer with fins and tubes that are use the same material.
Common Applications:HVAC Coils.
"L" Footed Fin has a lip at the base which is tension wound around the tube. This increases the connected area and increases the heat transfer connect area between the fin and the tube and decreases the exposed joints at the fin base.
Common Applications: Steam Coils, HVAC Coils.
Max. Working Temperature: 150 °C
Atmospheric Corrorsion Resisitance: OK
Mechanical Resistance: Poor
Fin Material: Copper, Aluminum
Base Tube materials: Any material available, such as Carbon steel Tube, A179, A192, A210, stainless tube A269/A213 T5 T11 T22 304 316
"LL" type fin tubes also called Overlapped "L" Fin tubes
The Overlapped "L" fin design has interlocking fins that are wound together to prevent movement and separation. The fin protects the entire tubes, so the designation works well for the applications where corrosion is a factor.
This type of finned tube is often used as an alternative to the more expensive extruded type fin in corrosive environments.
Common Applications: Steam Coils, Air Preheaters.
Max. Working Temperature: 180 °C
Atmospheric Corrorsion Resisitance: OK
Mechanical Resistance: Poor
Fin Material: Copper, Aluminum
Base Tube materials: Any material available, such as Carbon steel Tube, A179, A192, A210, stainless tube A269/A213 T5 T11 T22 304 316
KL fin tubes also named knurled finned tubes
Manufactured method is exactly as the 'L' finned tube except that the base tubes are knurled before application of these fin foot. After application, the fin foot is knurled into the corresponding knurling on the base tube thereby enhancing the bond between the fin and tube, resulting in improved heat transfer characteristics.
Max. Working Temperature: 260 °C
Atmospheric Corrorsion Resisitance: OK
Mechanical Resistance: Poor
Fin Material: Copper, Aluminum
Base Tube materials: Any material available, such as Carbon steel Tube, A179, A192, A210, stainless tube A269/A213 T5 T11 T22 304 316
