Revel in the strength of our unique L-shaped design, crafted to hold fins rigorously in place, ensuring resilience through heat cycling and high-velocity air vibration.
Our L-Foot Finned Tubes are available with the following exceptional fin variations:
Knurled Fin - Experience the robustness of an interference-fit fin, enhanced by mechanical knurling of the fin material on the tube wall for superior performance.
LL Fin - Double Overlap fin (Double LL) ensures comprehensive double strip thickness coverage, enveloping the entire base tube with precision.
Perforated L Fin - Innovatively designed with "tear drop" slits around the helix, optimizing airflow disruption for superior thermal efficiency.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Also known as Wrap-On Finned Tubes, ideal for applications under 300°F, offering low-temperature functionality and tube wall protection. Precision-crafted, L-Foot tension wound finned tubes feature a tightly wound thin aluminum fin strip, spiraling around the tube circumference. The fin strip forms a distinctive "foot" on one side, earning the name L-Foot, exemplifying innovative design. Meticulous winding ensures the foot adheres firmly to the tube's outer surface, optimizing contact. Each L's short horizontal limb intimately contacts the base tube, providing complete coverage for efficiency maximization. The tension during wrapping ensures the fin foot is securely seated on the tube, maintaining steadfast fin placement. Amplify your thermal management with L-footed finned tubing, crafted for maximum heat transfer at economical temperatures. Stand out with the exclusive L-shaped design, providing firm fin positioning against cyclical heat and vigorous air movement. This sophisticated fin delivers atmospheric protection to the tube wall, guarding against corrosion. The expansive contact surface between tube and finning amplifies heat transfer capabilities. Achieve remarkable efficiency and economic value with this cutting-edge fin design.
Prevent unraveling and maintain fin-tube connection integrity with expertly stapled fin ends, crucial for air cooler operations. This critical contact facilitates effective heat transfer from the tube wall, through the fin, to the surrounding air.
Advantages:
Perfectly suited for low-temperature applications, ensuring robust performance and durability.
Enjoy the cost-efficiency of this finning type, offering unparalleled economic advantages.
Easily replace failed fins, ensuring no wastage, and reuse the bare tube effortlessly.
No need for helical grooves, saving time and resources during production.
Capable of accommodating very thin-walled tubes, especially when using expensive alloy core tubes.
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
Steel making industry
Power plants
Air conditioning
Compressor coolers
KL Footed Fin / Knurled L Footed Fin
The KL fin, a marvel of engineering, stands out for its unique design and efficiency. This exceptional component is also widely recognized as the knurled L fin, distinguished by its superior performance. The finned tube mirrors the ingenuity of the Wrap-On fin. Crafted with a blend of Wrap-On and Embedded techniques, it showcases precision and innovation. Fins are meticulously crafted from strips shaped into an L form, comparable to the traditional L type, then skillfully rolled into a taper for a perfect curl. Helically wound under tension, the fin embraces the tube in a seamless and continuous loop, enhancing durability and efficiency. This design ensures the fin securely hugs the tube, optimizing thermal transfer efficiency. A rotating tool intricately knurls the base tube, with the fin foot being expertly knurled into this, forging a strong bond and exceptional thermal performance.
When the correct fin strip is employed, the foot of each fin seamlessly integrates with the next, eliminating any gaps for unmatched tube protection. This precise alignment acts as a shield, effectively safeguarding the tube from corrosion and degradation. Much like L fins, the ends are securely attached, preventing any unwinding and ensuring lasting performance. KL-Foot tension wound finned tubes are indispensable in metal-related applications, offering robust solutions. Capable of withstanding up to 320°C (608°F), they ensure reliability in diverse thermal environments.
Advantages:
Corrosion-resistant Tubes offer unparalleled protection and longevity.
Designed to resist vibration, enhancing operational stability and lifespan.
Withstanding temperatures soaring to 320°C (608°F), ensures enduring functionality.
High thermal and stress resistance, coupled with air corrosion protection, delivers a truly unique performance combination.
Capable of replacing any finned tube form, KL fins offer versatile and adaptable solutions.
LL-Foot Fin / Overlapped L
Derived from strips like the L type, the foot is carefully crafted into a double L shape, enabling a perfect curl with precision. Helically coiled under tension, the LL-Foot Fin - Overlapped L clings seamlessly onto the tube. Fin embraces the tube, with one fin gracefully overlapping the next, offering complete base tube coverage and protection. This comprehensive coverage shields the tube from corrosion, prolonging its operational life. Ideal for corrosive environments, this solution rivals costly extruded fins, offering a cost-effective alternative.
Similar to L fins, the ends are secured, ensuring stability and reliability. With a heat tolerance up to 350°F (177°C), the LL-type fin tube offers exceptional performance for demanding conditions.
