Product Parameters

L-Foot Finned Tube

Experience unparalleled efficiency with our L-footed finned tubing, expertly crafted to deliver maximum heat transfer even at lower temperatures, without breaking the bank. Marvel at the ingenious L-shaped design, meticulously engineered to secure fins with unwavering rigidity, ensuring resilience against heat cycling and high-velocity air vibrations.

Discover the versatility of the L-Foot Finned Tube, available in various fin configurations including:

Knurled Fin - An innovative interference fit fin, featuring mechanical knurling that seamlessly integrates the fin material with the tube wall surface for enhanced performance.

LL Fin - Double Overlap fin (the double LL) that provides comprehensive double strip thickness coverage, enveloping the entire base tube with precision.

Perforated L Fin - This advanced fin design creates distinctive "tear drop" slits along the helix to effectively disrupt air flow for superior heat exchange.

L-Foot Fin / Wrap-On Fin

L-Foot Tension Wound Finned Tubes Renowned as Wrap-On Finned Tubes, ideal for applications where temperatures remain below 300 degrees Fahrenheit, offering essential tube wall protection in low-temperature settings. Crafted to perfection, L-Foot tension wound finned tubes showcase a thin aluminium fin strip meticulously wound in a helical fashion around the tube's circumference. A defining 'foot' is artfully formed on one edge of the fin strip, giving rise to the name L-Foot. The strip is expertly wound around the tube, with the foot maintaining contact with the tube's surface, ensuring a snug fit. Each L's horizontal limb is strategically positioned to ensure full coverage of the base-tube surface. The fin strip's tension as it wraps around the tube firmly seats the fin foot, securing it steadfastly in place. L-footed finned tubing effortlessly delivers optimal heat transfer at lower temperatures. The robust L-shaped design steadfastly secures fins against heat cycling disturbances and high-velocity air vibrations. This fin configuration provides an added layer of atmospheric protection to guard the tube wall against corrosive elements. The expansive contact surface between the tube and finning significantly amplifies heat transfer capabilities. This fin design is the epitome of efficiency, blending outstanding performance with cost-effectiveness.

To prevent unraveling, fin ends are securely stapled, preserving the critical contact between the fin foot and tube for optimal cooler performance. This crucial contact facilitates seamless heat transfer from the tube wall through the fin, efficiently dispersing it into the surrounding air.

Advantages:

Ideal for low-temperature applications where performance and cost efficiency are paramount.

This finning type stands out as the most cost-effective method, offering substantial savings without compromising quality.

Production flexibility allows for easy removal of failed fins, enabling reuse of the bare tube for new finning.

No need for helical groves on the core tube, simplifying the manufacturing process.

Capable of accommodating fins on ultra-thin-walled tubes, this option is particularly advantageous when using high-cost alloy core tubes.

The tube confidently withstands temperatures up to 130°C, assuredly protected against 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 knurled L fin. This innovative finned tube design closely mirrors the Wrap-On fin and is crafted using both the Wrap-On and Embedded techniques. The fins are expertly formed from strips, meticulously shaped into an L configuration akin to the L type, and then artistically rolled into a taper that elegantly curls. Once perfected, it is helically wound onto the tube in a seamless continuous loop, tightly secured under tension. The fin embraces the tube with precision and care. Employing a spinning tool, the base tube is knurled, allowing the fin's foot to interlock perfectly with the base's knurling, ensuring a robust bond and enhanced thermal efficiency.

Using the correct fin strip, the foot of one fin artistically aligns against the next, leaving no gaps between the fins. This meticulous alignment serves as a shield against corrosion. Similar to the L fins, the ends are securely attached, preventing any unwinding. In the realm of metals, KL -Foot tension wound finned tubes are the go-to choice for optimal performance. Capable of enduring temperatures up to 320°C (608°F) for robust operation.

Advantages:

Corrosion-resistant Tubes

Vibration resistance

It withstands high temperatures up to 320°C (608°F) with ease.

A remarkable blend of high thermal performance, stress resistance, and air corrosion protection.

KL can seamlessly replace any form of finned tube.

LL-Foot Fin / Overlapped L

The fins are intricately crafted from strips, akin to the L type, but with the foot precision-engineered into a stepped double L shape, allowing it to curl gracefully. The LL-Foot Fin - Overlapped L is then meticulously helically coiled onto a tube under tension. The fin securely clasps the tube, with each fin elegantly overlapping the foot of the next, fully enveloping the base tube. This results in exceptional protection against corrosion. In corrosive environments, this tube is a cost-effective alternative to pricier extruded type fins.

Fins are firmly secured at each end as with L fins, ensuring durability. The LL-type fin tube is adept for temperatures reaching up to 350°F (177°C).

We offer a diverse range of finned tubes: tension wound, embedded, and extruded finned tubes.

Tension wound finned tubes are crafted by artistically winding a strip of aluminum or copper around the tube under tension. This strip winding technology diversifies into different fin types: L-Fin, LL-Fin, KL-Fin.

Embedded fins (G-Fins) are expertly crafted by winding aluminum or copper strip into a helical groove machined on the tube's outer surface.

Tension wound, embedded, and extruded finned tubes are vital for air coolers, with applications spanning:

Heat exchangers for power plants (including electric, nuclear, thermal, and geothermal)

Steam condensate systems
