L-Foot Finned Tube
Discover the epitome of efficiency with our L-footed finned tubing, expertly engineered to deliver superior heat transfer at reduced temperatures while maintaining exceptional cost-effectiveness. Crafted with a distinctive L-shaped design, this tubing ensures fins remain steadfast, enduring the rigors of heat cycling and resisting the challenges of high-velocity air vibrations.
Elevate your thermal solutions with the versatile L-Foot Finned Tube, available in the following sophisticated fin variations:
Knurled Fin A fin designed with precision, featuring mechanical knurling of the material to the tube wall surface for a robust interference fit.
LL Fin The Double Overlap fin, known as double LL, offers a double strip thickness coverage, ensuring the entire base tube is enveloped in excellence.
Perforated L Fin Ingeniously crafted, this variation incorporates 'tear drop' slits along the helix to disrupt airflow and enhance efficiency.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Also recognized as Wrap-On Finned Tubes, these are tailored for scenarios where temperatures remain below 300°F, ideal for low-temperature applications requiring tube wall protection. Constructed with a thin aluminum fin strip, these tubes are meticulously helically wound around the circumference, ensuring a snug fit. A 'foot' is skillfully crafted on one side of the fin strip, giving rise to the iconic L-Foot name. This strip is then expertly wound around the tube, with the foot firmly seated on the tube's outer surface. The short horizontal limb of the L intimately contacts the base-tube surface, offering comprehensive coverage. The tension applied during wrapping ensures the fin foot is securely seated against the tube, maintaining a steadfast hold. Experience unparalleled heat transfer at lower temperatures with our L-footed finned tubing. This exclusive L-shaped architecture ensures the fins remain steadfast against heat cycling and high air velocity vibrations. Offering a remarkable degree of atmospheric protection, this fin design shields the tube wall from potential corrosion. The extensive contact surface between the tube and the fin enriches heat transfer capabilities. This fin design embodies outstanding efficiency while remaining economically viable.
Fin ends are securely stapled to prevent unraveling, ensuring a consistent bond between the fin foot and the tube. This critical contact ensures optimal operation of air coolers, transferring heat seamlessly from the tube wall to the ambient air.
Advantages:
Perfectly suited for low-temperature applications.
This finning method stands out as the most cost-effective solution available.
Fins that do not meet standards can be effortlessly removed without damaging the tube, allowing it to be reused for finning.
No need exists for helical grove formation on the core tube, simplifying production.
Fins can be affixed to thin-walled tubes, especially beneficial when using costly alloys as the core tube.
These tubes withstand temperatures up to 130°C, avoiding atmospheric corrosion and 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 is also known as the distinguished knurled L fin. This sophisticated finned tube mirrors the Wrap-On fin, crafted using both advanced Wrap-On and Embedded techniques for unmatched performance. The fins are meticulously shaped from strips into an elegant L form. Comparable to the classic L type, they're rolled into a taper, ready to curl. Finely helically wound onto the tube under tension, these fins provide seamless continuity. The fin envelops the tube snugly, ensuring a firm embrace. A precision spinning tool knurls the base tube, integrating the fin's foot into this knurling. This fusion creates a robust bond, enhancing thermal efficiency.
Each fin foot aligns perfectly with the next, ensuring a flawless, gap-free fit when using the right fin strip. This perfect alignment protects the tube, serving as a shield against corrosion. Much like L fins, these are secured at each end, effectively preventing unwinding. In metal-centric applications, KL-Foot tension wound finned tubes are favored for their reliability and excellence. Capable of enduring up to 320°C (608°F) in operational temperatures.
Advantages:
Corrosion-resistant Tubes
Outstanding vibration resistance
Designed to withstand up to 320°C (608°F).
Exceptional thermal performance paired with stress resistance and air corrosion protection offers a unique advantage.
KL fins are a versatile replacement for any finned tube variant.
LL-Foot Fin / Overlapped L
Fins are crafted from strips in a refined L type manner, with the foot skillfully shaped into a precise stepped double L form, rolled into an inviting taper. The LL-Foot Fin - Overlapped L is deftly helically coiled onto a tube, secured under precise tension. The fin envelops the tube with finesse, each fin overhanging the next, fully covering the base tube. This coverage ensures superior protection against corrosion. In corrosive environments, this tube variant is a favored alternative to costlier extruded type fins.
Fins are firmly anchored at each end, mirroring L fin attachment methods. Ideal for environments up to 350°F (177°C), the LL-type fin tube is robust under challenging conditions.
