Product Parameters

L-Foot Finned Tube

Introducing the L-Foot Finned Tube, a marvel in heat exchange technology. This product delivers superior heat transfer performance even at lower temperatures, making it both an energy-efficient and cost-effective solution. The inventive L-shaped design ensures that fins are securely fastened, allowing them to endure the rigors of heat cycling and high-speed air vibrations without compromise.

Explore the versatility of the L-Foot Finned Tube with these available fin variations:

Knurled Fin - This variation features an interference fit fin, expertly crafted with mechanical knurling that seamlessly bonds the fin material to the tube's surface, maximizing durability.

LL Fin - Double Overlap fin (The double LL) offers a robust double layer of coverage, ensuring the base tube is entirely enveloped for enhanced protection and efficiency.

Perforated L Fin - This innovative design introduces 'tear drop' slits along the helix, ingeniously disrupting airflow for optimized heat exchange.

L-Foot Fin / Wrap-On Fin

L-Foot Tension Wound Finned Tubes Also known as Wrap-On Finned Tubes, these are ideal for applications with temperatures up to 300°F. Perfect for low-temperature scenarios demanding tube wall protection. Constructed from fine aluminium strips, these fins are meticulously wound around the tube, ensuring a snug fit and excellent heat conduction. The initial formation of a 'foot' on the fin strip is what gives the L-Foot its distinctive name. This strip is tightly coiled around the tube, ensuring the 'foot' remains in constant contact with the outer tube surface. The horizontal limb of each 'L' is carefully aligned to comprehensively cover the base-tube surface. The tension in the fin strip, when wrapped, ensures a firm and unwavering contact of the fin foot against the tube, securing it in place. The L-footed finned tubing is engineered for maximum heat transfer efficiency at economical temperatures. The robust L-shaped configuration guarantees the fins remain steadfast through heat fluctuations and fast-moving air vibrations. This design not only enhances thermal performance but also provides a degree of corrosion protection, safeguarding the tube against atmospheric damage. With an expansive contact area between tube and fin, this design optimizes heat transfer capabilities. A fusion of efficiency and economy, this fin design is a testament to cost-effective engineering ingenuity.

To maintain the integrity of the finning, the fin ends are securely stapled, preventing unravelling and preserving the essential contact between the fin foot and tube. This secure contact is pivotal, as it allows effective heat transfer from the tube wall to the fins and ultimately to the ambient air, enhancing cooler performance.

Advantages:

Ideal for low-temperature applications, offering unparalleled efficiency.

Economically advantageous, this finning type stands out as the most cost-effective option available.

Fins are replaceable during production, allowing for the reuse of bare tubes in the finning process.

No need for a helical groove on the core tube, simplifying the production process.

Fins can be applied to thin-walled tubes, perfect for using costly alloys as core tubes without sacrificing durability.

With a temperature tolerance of up to 130°C, this tube withstands corrosion and thermal stress elegantly.

Application:

Essential for Oil and Gas Refineries

Crucial in Petroleum, Chemical, and Petrochemical Industries

Vital in Natural Gas Treatment

Integral to the Steel Making Industry

Indispensable for Power Plants

Ideal for Air Conditioning Systems

Perfect for Compressor Coolers

KL Footed Fin / Knurled L Footed Fin

The KL fin is also known as the knurled L fin. This finned tube is a remarkable innovation, closely akin to the Wrap-On fin. It is crafted using a synergy of both Wrap-On and Embedded techniques, showcasing superior craftsmanship. The fins emerge from strips meticulously prepared into an L shape. They resemble the classic L type, then artfully rolled into a taper, giving rise to a graceful curl. Subsequently, these fins are helically wound onto the tube, creating a continuous loop under precise tension. The tube is securely enveloped by the embracing fin. A spinning tool skillfully knurls the base tube. The foot of the fin is then intricately knurled into the base tube, forging a tight bond that enhances thermal performance remarkably.

With the optimal fin strip, each foot snugly aligns with the adjacent fin, ensuring a seamless, gap-free shield. This meticulous assembly offers formidable protection against corrosion. Similar to L fins, each end of the fins is securely anchored to prevent unwinding. In metal applications, the KL-Foot tension wound finned tubes stand out as a preferred choice. Designed for robustness, these tubes tolerate temperatures up to a peak of 320°C (608°F).

Advantages:

Corrosion-resistant Tubes

Vibration resistance

Remarkable endurance against temperatures soaring up to 320°C (608°F).

A rare combination of high thermal performance and stress resistance, coupled with exceptional protection from air corrosion.

The KL can effortlessly substitute any type of finned tube.

LL-Foot Fin / Overlapped L

Engineered similarly to the L type, the foot is adeptly crafted into a sophisticated stepped double L shape and rolled into a taper, allowing it to curl elegantly. Next, the LL-Foot Fin - Overlapped L is intricately helically coiled onto the tube with precision tension. The fin securely clings to the tube, with each fin gracefully overhanging the foot of the next, ensuring the base tube is completely shrouded. Such a construction offers exceptional corrosion protection for the tube. In corrosive environments, this type of tube is a popular alternative to the more costly extruded fin type.

Fins are firmly secured at each end, akin to L fins. The LL-type fin tube is robustly designed for settings up to 350 degrees Fahrenheit (177°C).
