L-Foot Finned Tube
Our L-footed finned tubing is a marvel of engineering, combining high efficiency with cost-effectiveness. It delivers superior heat transfer even at reduced temperatures, making it an ideal choice for various applications. The innovative L-shaped design ensures that the fins remain firmly in place, enduring the rigors of heat cycling and the challenges of high-velocity air vibrations with unwavering stability.
Discover the versatility of the L-Foot Finned Tube, available in these exciting fin variations:
Knurled Fin - This fin features a unique interference fit, utilizing mechanical knurling to secure the fin material tightly to the tube wall surface, enhancing performance.
LL Fin - Experience the robust double overlap fin configuration, also known as double LL, which provides a dual-layer thickness coverage enveloping the entire base tube for unmatched protection.
Perforated L Fin - This innovative design introduces 'tear drop' slits along the fin helix, disrupting airflow to enhance thermal efficiency.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Recognized as Wrap-On Finned Tubes, these are ideal for low-temperature setups where the temperature remains below 300°F, ensuring reliable protection for the tube wall. Constructed with precision, these tubes feature a slender aluminum fin strip, expertly wound in a helical pattern around the tube's circumference. An 'L-foot' is meticulously formed at one end of the fin strip, providing the namesake for this innovative design. The fin strip is securely wrapped around the tube, with the foot exerting firm contact on the tube's surface for optimal performance. The horizontal limb of each L maintains continuous contact with the base tube, ensuring complete protective coverage. Tension in the fin strip as it is wound secures the fin foot against the tube, affording a steadfast connection that enhances durability. This L-footed finned tubing guarantees top-tier heat transfer performance at lower operational temperatures, optimizing energy use. Our L-shaped design firmly secures the fins, enabling them to withstand the challenges posed by heat cycling and high-velocity air vibrations. This innovative fin structure provides enhanced atmospheric protection for the tube wall, safeguarding against corrosion. The expansive contact surface between the tube and fin amplifies heat transfer capabilities, making it a powerhouse of efficiency. Crafted with precision, this finned tube design delivers exceptional efficiency while maintaining cost-effectiveness, setting a new standard in the industry.
To ensure unyielding performance, the ends of the fins are stapled, preventing unwinding and securing the vital contact between fin and tube. Maintaining critical contact between fin foot and tube is essential for effective air cooling, as heat transfers seamlessly from the tube wall through the fin to the surrounding air.
Advantages:
Perfectly suited for low-temperature applications, offering tailored solutions for unique operational challenges.
This finning type stands out as the most cost-efficient method when compared to other alternatives.
Fins that fail can be effortlessly removed during manufacturing, allowing the bare tube to be reused, increasing sustainability.
No need for a helical groove over the core tube, simplifying the process and reducing costs.
Ideal for use with very thin-walled tubes, especially beneficial when using expensive alloys as the core tube, optimizing resource use.
Capable of withstanding temperatures up to 130°C, this tube offers remarkable resilience against atmospheric corrosion and thermal stress.
Application:
Oil and gas refineries
Petroleum, chemical, and petrochemical industries
Natural gas treatment
Steelmaking industry
Power plants
Air conditioning
Compressor coolers
KL Footed Fin / Knurled L Footed Fin
The KL fin is also renowned as the Knurled L fin. This finned tube bears a striking resemblance to the Wrap-On fin and is crafted using a blend of Wrap-On and Embedded techniques. The fins are meticulously formed from strips, shaped into an L configuration similar to the L type, then artistically rolled into a taper to create an elegant curl. Subsequently, it is helically wound onto the tube, forming a seamless continuous loop under precise tension. The tube is gracefully embraced by the fin, offering a snug fit. A sophisticated spinning tool knurls the base tube, and then the foot of the fin is ingeniously interlocked with the knurling of the base tube, ensuring a firm bond and enhanced thermal efficiency.
The foot of each fin meets the subsequent fin without gaps if the correct fin strip is used, signifying flawless integration. This design is instrumental in safeguarding the tube against corrosion. In a manner akin to L fins, the fins are expertly secured at each end to thwart unwinding. KL -Foot tension wound finned tubes are predominantly applied in metal-related scenarios. Suitable for a maximum operating temperature of 320°C (608°F)
Advantages:
Corrosion-resistant Tubes
Vibration resistance
Capable of enduring temperatures up to 320°C (608°F).
Exquisite thermal performance and stress resistance paired with corrosion protection make it a unique offering.
KL can seamlessly replace any form of finned tube.
LL-Foot Fin / Overlapped L
The fins are crafted from strips similar to the L type, but the foot is meticulously shaped into a refined stepped double L configuration and rolled to curl elegantly. The LL-Foot Fin - Overlapped L is then deftly coiled onto a tube under calculated tension. The fin securely grips the tube, with each fin elegantly extending over the foot of the subsequent fin, entirely covering the base tube. This design robustly protects the tube from corrosion. In corrosive environments, this tube type is a favored alternative to the pricier extruded fin type.
Fins are firmly fixed at each end, mirroring the method used for L fins. The LL-type fin tube is adept for temperatures reaching up to 350°F (177°C).
