Product Parameters

L-Foot Finned Tube

Welcome to the pinnacle of efficiency and cost-effectiveness with our L-footed finned tubing! Experience superior heat transfer, even at lower temperatures, without breaking the bank. Ingeniously crafted with a unique L-shaped design, these fins are held firmly in place to withstand the challenges of heat cycling and high-velocity air vibration.

For added versatility, the L-Foot Finned Tube can be customized with the following fin variations:

Knurled Fin - Engineered with mechanical knurling, this interference fit fin ensures a robust bond between the fin material and tube wall surface.

LL Fin - Featuring double overlap (the double LL) for comprehensive coverage, offering double-layered protection to the entire base tube.

Perforated L Fin - Enhanced with "tear drop" slits along the helix, this fin design disrupts airflow for improved performance.

L-Foot Fin / Wrap-On Fin

L-Foot Tension Wound Finned Tubes Revered as Wrap-On Finned Tubes, these are ideal for applications where temperatures remain below 300°F, providing essential protection for the tube wall in low-temperature scenarios. Constructed with a thin aluminum fin strip meticulously wound helically around the tube circumference for optimal performance. A strategically formed "foot" on one side of the fin strip lends the name L-Foot to this innovative design. The strip is carefully wound around the tube, ensuring the foot maintains strong contact with the tube's outer surface. The short horizontal limb of each L ensures complete coverage of the base-tube surface for unmatched protection. By maintaining tension in the fin strip during the wrapping process, the fin foot is securely seated and held firmly in place. L-footed finned tubing delivers unsurpassed heat transfer efficiency, even at reduced temperatures. The robust L-shaped design ensures fins remain steadfast during heat cycling and high-velocity vibrations. This fin provides a protective shield against atmospheric corrosion, ensuring longevity and reliability. The expansive contact surface between the tube and fin enhances thermal conductivity, optimizing heat transfer. This fin design represents the epitome of efficiency and economic viability.

Fin ends are meticulously stapled to prevent unraveling, ensuring continuous contact and optimal heat transfer. This crucial contact is vital for air cooler efficiency, transferring heat seamlessly from tube to air.

Advantages:

Perfectly suited for low-temperature applications

The most economical finning method available, ensuring unrivaled cost efficiency.

Easily removable failed fins during production, allowing bare tubes to be reused, enhancing sustainability.

No need for helical grooves on the core tube, simplifying production and reducing costs.

Fins can be applied to very thin-walled tubes, ideal for expensive alloy core tubes.

Capable of withstanding temperatures up to 130°C without risk of corrosion or stress.

Application:

Oil and gas refineries

Petroleum, chemical, and petrochemical industries

Natural gas treatment facilities

Steel manufacturing industry

Power generation plants

Air conditioning systems

Compressor coolers

KL Footed Fin / Knurled L Footed Fin

The KL fin is also known as the knurled L fin. This innovative finned tube mirrors the Wrap-On fin and is crafted using both Wrap-On and Embedded techniques, ensuring robust performance and versatility. The fins originate from strips meticulously shaped into an L form, akin to the L type, and expertly rolled into a taper that elegantly encourages curling. These are then helically wound with precision onto the tube, forming a continuous loop under expertly controlled tension. The fin seamlessly embraces the tube. A sophisticated spinning tool knurls the base tube, enabling the fin's foot to integrate tightly, ensuring an enhanced thermal bond and superior performance.

When the appropriate fin strip is employed, the foot of each fin perfectly aligns with the next, leaving no gaps. This meticulous construction provides optimal protection against corrosion for the tube. In a manner akin to L fins, these fins are securely anchored at each end to prevent unwinding, ensuring longevity. KL-Foot tension wound finned tubes are the top choice in metal applications, renowned for their reliability and efficiency. Capable of withstanding temperatures soaring up to 320°C (608°F), these tubes promise resilience and durability.

Advantages:

Corrosion-resistant Tubes

Vibration resistance

Impressively tolerates heat up to 320°C (608°F) without compromising integrity.

A unique amalgamation of high thermal performance, stress resistance, and unparalleled protection from air corrosion.

KL offers a seamless replacement for any type of finned tube.

LL-Foot Fin / Overlapped L

The fins are crafted from strips, similar to L type, but with a precisely stepped double L shape, expertly rolled into a taper for optimal curling. The LL-Foot Fin - Overlapped L is then helically coiled onto the tube under tight control and tension. The fin gracefully clings to the tube, with each fin slightly overhanging, ensuring complete coverage and protection of the base tube. This construction provides exceptional corrosion protection for the tube. In demanding corrosive environments, this tube serves as an economical alternative to the pricier extruded type fin.

Fins are secured at each end, mirroring the method used for L fins, to ensure lasting stability. The LL-type fin tube is adept at handling temperatures up to 350°F (177°C), offering robust performance.
