L-Foot Finned Tube
Experience unparalleled efficiency with our highly cost-effective L-Footed Finned Tubing, designed to deliver optimum heat transfer even at lower temperatures. The ingeniously crafted L-shaped design ensures the fins are held securely, perfectly engineered to endure heat cycling and high-velocity air vibrations.
Explore the versatility of the L-Foot Finned Tube with these innovative fin variations:
Knurled Fin - Features a robust interference fit, with mechanical knurling that expertly bonds the fin material to the tube wall surface.
LL Fin - The Double Overlap fin (Double LL) offers comprehensive, double strip thickness coverage across the entire base tube, enhancing durability and performance.
Perforated L Fin - The fin face's unique enhancement creates distinctive "tear drop" slits around the helix, effectively disrupting airflow for superior performance.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Also recognized as Wrap-On Finned Tubes, these are ideal for applications with temperatures below 300 degrees Fahrenheit, offering necessary tube wall protection for low-temperature scenarios. These tubes boast a finely wound thin aluminum fin strip, helically encircling the tube circumference for maximum efficacy. A defining "foot" is crafted on one side of the fin strip, giving the L-Foot its name. This strip is meticulously wound around the tube, with the foot precisely aligning on the tube's outer surface for enhanced stability. Each L's short horizontal limb makes full contact with the base-tube surface, ensuring comprehensive coverage. The fin strip's tension during wrapping ensures the fin foot is securely seated, maintaining firm placement for optimal functionality. L-footed finned tubing offers unrivaled heat transfer efficiency, even at reduced temperatures. The distinct L-shaped design assures the fins remain firmly in place, adeptly handling heat cycling and high-velocity air movements. This innovative fin design offers a protective barrier for the tube wall, shielding it from atmospheric corrosion. An expansive contact surface between the tube and finning significantly boosts heat transfer efficiency. This design epitomizes efficiency, delivering high performance at an economical cost.
Fin ends are expertly stapled to prevent the aluminum fin from unravelling, maintaining crucial contact between the fin foot and tube. This vital contact ensures efficient operation of air coolers, facilitating seamless heat transfer from the tube wall through the fin to ambient air.
Advantages:
Perfectly suited for low-temperature applications.
This finning type offers the most cost-effective solution compared to other methods.
Fins that fail can be effortlessly removed during production, allowing the bare tube to be reused for finning, enhancing sustainability.
No need to carve a helical groove into the core tube, simplifying the production process.
Fins can be placed on ultra-thin-walled tubes, especially beneficial when using expensive alloys for the core tube.
The tube can endure temperatures up to 130°C without succumbing to atmospheric corrosion or thermal stress.
Application:
Oil and gas refineries
Petroleum, chemical, and petrochemical industries
Natural gas treatment
Steelmaking industry
Power plants
Air conditioning systems
Compressor coolers
Introducing the KL Footed Fin, also recognized as the Knurled L Footed Fin.
The KL fin is an advanced fin design that offers unique benefits. This fin, widely known as the knurled L fin, showcases superior performance. This innovative finned tube mirrors the Wrap-On fin, crafted with a fusion of Wrap-On and Embedded technique excellence. Our fins are meticulously prepared from strips shaped into an L-like structure, skillfully rolled into a taper to achieve a distinct curl. The result is a helically wound fin applied under tension, forming a continuous loop around the tube. The fin envelops the tube snugly, enhancing its contact and performance. A precision spinning tool meticulously knurls the base tube, facilitating the integration of the fin's foot, culminating in a firm bond and augmented thermal efficiency.
With the right fin strip, each fin foot seamlessly meets the next, eliminating gaps and optimizing functionality. This flawless alignment aids in shielding the tube from corrosive elements. Similar to L fins, our design ensures end-to-end attachment to preserve fin stability. KL-Foot tension wound finned tubes are the go-to choice for metal-related applications, setting a benchmark in performance. Operating Temperature Capabilities: Withstands temperatures up to 320°C (608°F).
Key Advantages:
Tubes with Exceptional Corrosion Resistance
Exceptional Resistance to Vibration
Engineered to endure extreme temperatures of up to 320°C (608°F).
Combining high thermal performance and stress resistance with unparalleled air corrosion protection, offering a distinctive solution.
KL fins are versatile, suitable for replacing any existing finned tube type.
Discover the LL-Foot Fin, also known as the Overlapped L Fin.
These fins are expertly crafted from strips, mirroring the L type, but with a foot that transforms into a sophisticated double L shape, beautifully rolled into a taper for a perfect curl. The LL-Foot Fin - Overlapped L is expertly helically coiled onto the tube, ensuring optimal tension and performance. This fin clings closely to the tube, with one fin gently overlapping the foot of the next, leading to complete tube coverage. This comprehensive coverage delivers exceptional protection against corrosion. In challenging corrosive environments, this tube is a preferred alternative to more costly extruded fin types.
Just like L fins, the LL fins are securely anchored at both ends, maintaining stability. The LL-type fin tube is engineered to function efficiently at temperatures reaching up to 350°F (177°C).
