Product Parameters

L-Foot Finned Tube

Experience unparalleled efficiency with the L-footed finned tubing, a marvel in engineering that combines cost-effectiveness with optimal heat transfer capabilities, especially at lower temperatures. Ingeniously crafted, the unique L-shaped design ensures fins remain steadfast, withstanding the challenges of heat cycling and the rigors of high-velocity air vibration.

Explore the versatility of the L-Foot Finned Tube, available in the following innovative fin variations:

Knurled Fin - Experience the robust performance of an interference fit fin, meticulously engineered with mechanical knurling to seamlessly integrate with the tube wall surface.

LL Fin - Discover the superior protection of Double Overlap fin (the double LL), offering double strip thickness coverage across the entire base tube for enhanced durability.

Perforated L Fin - Innovation at its best, this fin enhancement introduces 'tear drop' slits along the helix, skillfully disrupting airflow for improved efficiency.

L-Foot Fin / Wrap-On Fin

L-Foot Tension Wound Finned Tubes Also recognized as Wrap-On Finned Tubes, these are ideal for applications requiring low-temperature resilience, effectively protecting tube walls up to temperatures of 300 degrees Fahrenheit. Crafted with precision, L-Foot tension wound finned tubes feature a thin aluminum fin strip, expertly wound in a helical fashion to encircle the tube with precision. A 'foot' is intricately formed on one side of the fin strip, giving rise to the name L-Foot. The strip is then meticulously wound, ensuring the foot adheres securely to the tube's outer surface, promising unwavering reliability. The ingenious design ensures each L's horizontal limb makes full contact with the base-tube surface, offering complete coverage and enhanced protection. The fin strip's tension, combined with the wrap, ensures the fin foot is firmly seated, maintaining its grip and functionality under all conditions. Maximize your heat transfer potential with L-footed finned tubing, optimized for performance even at lower temperatures. Uniquely designed, the L-shaped fins provide steadfast support, enduring the demands of heat cycling and high-velocity air movements with ease. This fin design offers significant atmospheric protection against corrosion, safeguarding the tube wall for long-term reliability. A broad contact surface between the tube and finning significantly boosts heat transfer efficiency, ensuring optimal performance. Cost-effective yet supremely efficient, this fin design delivers unmatched performance and value.

Stapled ends fortify the fins, preventing unraveling and ensuring the crucial contact between the fin foot and the tube remains intact. This vital contact is pivotal for effective air cooler operation, enabling seamless heat transfer from the tube wall to the ambient air.

Advantages:

Perfectly suited for low-temperature applications, ensuring optimal performance and reliability.

The most cost-effective finning method available, providing exceptional value without compromising performance.

Easily replace failed fins during production, allowing the bare tube to be reused for future finning, enhancing sustainability.

Eliminates the need for a helical grove on the core tube, streamlining production and reducing complexity.

Enables the use of very thin-walled tubes, especially advantageous when utilizing expensive alloys as core tubes.

The tube can endure temperatures up to 130°C, withstanding atmospheric corrosion and thermal stress effortlessly.

Application:

Refine your processes in oil and gas refineries with cutting-edge technology.

Elevate performance in the petroleum, chemical, and petrochemical industries with superior heat transfer solutions.

Enhance natural gas treatment with advanced efficiency and reliability.

Optimize operations in the steel-making industry with durable and efficient heat transfer solutions.

Power plants benefit from reliable and efficient heat management technology.

Revolutionize air conditioning systems with superior heat transfer technology for enhanced comfort and efficiency.

KL Footed Fin / Knurled L Footed Fin

The KL fin is also known as the knurled L fin. This finned tube mirrors the Wrap-On fin closely, crafted using an integration of both Wrap-On and Embedded techniques. The fins are meticulously manufactured from strips shaped into an L configuration, akin to the L type, then skillfully rolled into a taper, naturally curling. Subsequently, it is helically wound onto the tube in an uninterrupted loop under precise tension. The fin embraces the tube with a snug fit. A rotating tool knurls the base tube, while the foot of the fin is seamlessly knurled into the base tube's grooves, ensuring a robust bond and enhanced thermal efficiency.

With the correct fin strip, each fin's foot aligns perfectly against the subsequent fin, leaving no gaps between them. This design significantly enhances the tube's resistance to corrosion. Analogous to L fins, the fins are securely fastened at each end to avert any unwinding. For metal-involving applications, KL -Foot tension wound finned tubes are predominantly utilized. Handles temperatures up to 320°C (608°F) effortlessly.

Advantages:

Corrosion-resistant Tubes

Vibration resistance

Capable of withstanding temperatures reaching up to 320°C (608°F).

High thermal and stress resistance, paired with exceptional protection from air corrosion, offers an unparalleled combination.

KL can seamlessly replace any finned tube variant.

LL-Foot Fin / Overlapped L

The fins are crafted from strips similar to the L type, yet the foot is meticulously formed into a precisely controlled stepped double L design, taper-rolled to induce curling. The LL-Foot Fin - Overlapped L is then helical wound onto a tube under optimal tension. The fin adheres closely to the tube, with one fin overlapping significantly onto the foot of the subsequent fin, ensuring complete coverage of the base tube. This structure ensures robust protection of the tube from corrosive damage. In corrosive environments, this tube design is a preferred cost-effective alternative to the pricier extruded fin type.

Fins are anchored at each end similarly to L fins for security. The LL-type fin tube adeptly handles temperatures up to 350 degrees Fahrenheit (177°C).
