L-Foot Finned Tube
Highly efficient yet cost-effective, the L-footed finned tubing offers unparalleled heat transfer efficiency at reduced temperatures, making it a smart choice for optimizing thermal performance. The exclusive L-shaped design ensures the fins are held securely, allowing them to withstand rigorous heat cycling and high-velocity air vibrations, safeguarding the system's integrity and performance.
The versatile L-Foot Finned Tube is available in the following innovative fin variations:
Knurled Fin - An advanced interference fit type fin, featuring mechanical knurling that seamlessly integrates the fin material with the tube wall surface for superior strength and durability.
LL Fin - Double Overlap fin (the double LL) offers enhanced protection with dual strip thickness coverage that thoroughly envelops the entire base tube, ensuring reliable operation.
Perforated L Fin - This fin innovation features 'tear drop' slits around the helix, strategically designed to disrupt air flow and enhance thermal exchange efficiency.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Commonly known as Wrap-On Finned Tubes, these are ideal for settings where temperatures are below 300 degrees Fahrenheit, providing necessary tube wall protection in low-temperature applications. The L-Foot tension wound finned tubes are crafted from thin aluminum fin strips, meticulously wrapped helically around the tube circumference for optimal heat distribution. A 'foot' is skillfully shaped on one side of the fin strip, giving rise to the distinctive L-Foot design. The fin strip is expertly wound around the tube, with the 'foot' making firm contact with the outer surface, ensuring robust attachment. Each L's short horizontal limb is strategically positioned to maintain complete contact with the base-tube surface, enhancing thermal conductivity. Tension within the fin strip as it wraps around the tube is crucial, as it ensures the fin foot is securely seated, maintaining firm positioning and maximizing heat transfer. The L-footed finned tubing is renowned for its exceptional heat transfer capabilities at reduced temperatures, ensuring efficient thermal management. The sophisticated L-shaped design robustly secures the fins, enabling them to endure intense heat cycling and high-velocity air turbulence with ease. This fin design not only provides outstanding heat transfer but also offers a degree of atmospheric protection against tube wall corrosion, prolonging equipment lifespan. The expansive contact surface between the tube and the finning significantly amplifies heat transfer efficiency, making it a top choice for thermal applications. This innovative fin design is not only highly efficient but also remarkably cost-effective, offering superior performance at an economical price.
Fin ends are meticulously stapled to prevent the aluminum fin from unraveling, ensuring sustained contact between the fin foot and the tube, essential for optimal heat transfer in air coolers. This secure fin-tube contact is pivotal, as it facilitates the transfer of heat from the tube wall through the fin and into the ambient air, maximizing cooling efficiency.
Advantages:
Especially suited for low-temperature applications, providing reliable performance and durability.
Among finning types, this method stands out as the most cost-effective, delivering exceptional value and efficiency.
Easily remove failed fins during production and reuse the bare tube for finning, ensuring cost-effective operation and sustainability.
No helical groove is necessary on the core tube, simplifying production and reducing costs.
Fins can be applied to very thin-walled tubes, especially advantageous when employing expensive alloys as the core tube, optimizing material use.
The tube is designed to withstand temperatures up to 130°C, offering robust resistance against atmospheric corrosion and thermal stress.
Application:
Oil and gas refineries
Petroleum, chemical, and petrochemical industries
Natural gas treatment facilities
Steel manufacturing industry
Power generation plants
Air conditioning systems
Compressor cooler units
KL Footed Fin / Knurled L Footed Fin
The KL fin is also elegantly known as the knurled L fin. This finned tube is designed with finesse, almost identical to the Wrap-On fin, crafted using both Wrap-On and Embedded techniques for superior performance. The fins are crafted from strips, artfully prepared into an L shape comparable to the L type, then rolled into a graceful taper that encourages a natural curl. It is then helically wound onto the tube in a seamless, continuous loop under precise tension. The tube is embraced tightly by the fin. A sophisticated spinning tool knurls the base tube, allowing the foot of the fin to be securely knurled into the base tube's knurling, resulting in a robust bond and enhanced thermal performance.
The foot of one fin seamlessly meets the next fin when using the correct fin strip, creating a flawless, space-free assembly. This design innovation significantly aids in protecting the tube from corrosion. Similar to L fins, these fins are firmly attached at each end to prevent unwinding, ensuring durability. In demanding metal applications, KL-Foot tension wound finned tubes are the go-to choice. Maximum operating temperature: up to 320°C (608°F)
Unparalleled Advantages:
Corrosion-resistant Tubes
Vibration resistance for enhanced longevity
Capable of withstanding temperatures soaring up to 320°C (608°F).
Combining high thermal performance, stress resistance, and air corrosion protection in a unique synergy.
KL fins are adaptable, capable of replacing any form of finned tube.
LL-Foot Fin / Overlapped L
The fins are meticulously created from strips, similar to the L type, but with a precisely controlled stepped double L shape, rolled into a taper for an elegant curl. The LL-Foot Fin - Overlapped L is then helically coiled onto a tube under deliberate tension. The fin firmly clings to the tube, with each fin overhanging the foot of the next, ensuring the base tube is entirely covered. This comprehensive covering ensures excellent protection from corrosion. In corrosive environments, this tube type is a favored alternative to the pricier extruded type fin.
Fins are secured at each end just like L fins, ensuring they stay in place. The LL-type fin tube gracefully accommodates temperatures up to 350 degrees Fahrenheit (177°C).
