L-Foot Finned Tube
Experience the pinnacle of heat transfer efficiency with our L-Footed Finned Tubing. This cutting-edge solution is designed to deliver maximum heat transfer performance at lower temperatures, offering cost-effectiveness without compromising on quality. Boasting a unique and innovative L-shaped design, our fins are engineered to stay firmly in place, withstanding challenging heat cycling and high-velocity air vibrations effortlessly.
Explore the versatile options of our L-Foot Finned Tube, available with the following fin variations:
Knurled Fin - Featuring an interference fit, this fin type is intricately knurled to create a durable mechanical bond with the tube wall surface.
LL Fin - The Double Overlap Fin (double LL) ensures double strip thickness, providing comprehensive coverage of the base tube.
Perforated L Fin - Ingeniously designed, this fin comes with 'tear drop' slits that effectively disrupt air flow across the helix, enhancing performance.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Also known as Wrap-On Finned Tubes, these are tailored for applications involving temperatures up to 300 degrees Fahrenheit, ideal for low-temperature situations requiring robust tube wall protection. Crafted from a slender aluminium fin strip, these tubes are meticulously wound helically, encasing the tube circumference tightly for optimum performance. The distinctive 'L-Foot' begins its formation on one side of the fin strip, setting the foundation for its namesake. Wound with precision, the 'foot' rests firmly on the tube's outer surface, enhancing the bond. Each short horizontal limb of the L is strategically in contact with the base-tube surface, ensuring complete coverage. The tension applied during the winding process secures the fin foot against the tube, maintaining the fin's stability. Our L-footed finned tubing excels in delivering superior heat transfer, especially at lower temperatures. The robust L-shaped design ensures the fins remain steadfast, even under intense heat cycling and high-speed air movement. Enjoy the added benefit of atmospheric protection, safeguarding the tube wall against corrosion with this fin. The expansive contact area between the tube and finning significantly boosts heat transfer efficiency. Revel in the remarkable efficiency and cost effectiveness of this innovative fin design.
End assurance: Fin ends are stapled to prevent unraveling, ensuring a stable contact between the fin foot and tube. This crucial contact is paramount for air cooler efficiency, transferring heat seamlessly from the tube to surrounding air.
Advantages:
Perfectly suited for low-temperature applications.
This finning type stands out as the most economical compared to other methods.
Easily replaceable: Failed fins can be removed during production, allowing the bare tube to be reused for finning.
No helical groove required on the core tube, simplifying the process.
Fins can be applied to ultra-thin-walled tubes, an advantage when utilizing costly alloys as the core tube.
Tubes can endure temperatures up to 130°C, resisting atmospheric corrosion and thermal stress.
Application:
Ideal for Oil and Gas Refineries
Extensive use in Petroleum, Chemical, and Petrochemical Industries
Effective in Natural Gas Treatment
Suitable for Steel Making Industry
Power Plant Applications
Air Conditioning Solutions
Compressor Coolers
KL Footed Fin / Knurled L Footed Fin
The KL fin is also popularly referred to as the knurled L fin. This exceptional finned tube closely resembles the Wrap-On fin and is crafted using the advanced Wrap-On and Embedded techniques. The fins are meticulously fashioned from strips expertly shaped into an L form, akin to the L type, and are then rolled into a precise taper that encourages a graceful curl. Following this, it is helically and seamlessly wound onto the tube in a continuous loop under optimal tension. The fin embraces the tube with a snug, protective grip. Using a specialized spinning tool, the base tube is expertly knurled, allowing the fin's foot to integrate flawlessly into the base tube's knurling, resulting in a secure bond and enhanced thermal efficiency.
When the correct fin strip is applied, each fin's foot aligns perfectly with the next, ensuring there is absolutely no gap between fins. This precise alignment aids in safeguarding the tube against corrosion. Similar to L fins, these fins are securely attached at each end to prevent any unwinding. In metal-related applications, KL-Foot tension wound finned tubes are the premium choice. Operates flawlessly up to a maximum temperature of 320°C (608°F).
Advantages:
Corrosion-resistant Tubes
Exceptional Vibration Resistance
Capable of withstanding temperatures as high as 320°C (608°F).
A remarkable combination of high thermal performance, stress resistance, and superior protection against air corrosion.
Versatility defined: KL fins can replace any form of finned tube.
LL-Foot Fin / Overlapped L
These fins are crafted from strips in a manner similar to the L type, with the foot meticulously shaped into a precisely controlled stepped double L form, then rolled into a taper that allows it to curl elegantly. The LL-Foot Fin - Overlapped L is then expertly helically coiled onto a tube, maintaining tension throughout the process. The fin securely clings to the tube, with one fin gracefully overhanging the foot of the next, ensuring the base tube is fully shielded. This configuration offers outstanding protection against corrosion, safeguarding the tube effectively. In corrosive environments, this tube style is frequently preferred over more costly extruded type fins.
As with L fins, these fins are securely fastened at each end to maintain integrity. The LL-type fin tube is optimally suited for temperatures up to 350 degrees Fahrenheit (177°C).
