Perforated L Fin - Elevate airflow dynamics with our Perforated L Fin, featuring strategic tear-drop slits along the helix, designed to optimize air flow distribution and efficiency.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Also revered as Wrap-On Finned Tubes, these are crafted for applications where temperatures are capped at around 300°F. Perfectly suited for low-temperature environments requiring some tube wall protection. The construction features an aluminium fin strip intricately wound in a helical fashion around the tube's circumference, ensuring precision and stability. A distinctive 'foot' is crafted on one side of the fin strip, giving rise to the distinctive name, L-Foot. This strip is then meticulously wound around the tube, with the foot ensuring stable contact along the tube's outer surface. The horizontal limb of each L directly engages with the base-tube, providing comprehensive coverage for enhanced protection. The fin strip's tension serves a dual purpose: exerting forceful seating of the fin foot on the tube while simultaneously securing the fin in place with remarkable stability. Our L-footed finned tubing masters the art of maximizing heat transfer efficiency, even under cooler temperature conditions. With a groundbreaking L-shaped design, fins are held with unmatched firmness, engineered to endure the rigors of heat cycling and high-velocity air vibrations. This fin design also offers a layer of atmospheric protection against corrosion, extending the lifespan of the tube wall. The fin's extensive contact surface with the tube exemplifies enhanced heat transfer capabilities, making it a top-tier solution. This ingenious fin design strikes a perfect balance between efficiency and cost-effectiveness, meeting diverse application requirements with ease.
The fin ends are securely stapled to prevent unraveling of the aluminium fin, maintaining critical contact between the fin foot and tube. Ensuring this contact is vital for air cooler functionality, as it facilitates the transfer of heat from the tube wall through the fin to the ambient air.
Advantages:
Ideal for low-temperature applications, offering dependable performance.
This finning type stands out as the most cost-effective method when compared to other alternatives.
Failed fins can be effortlessly removed during production, allowing the bare tube to be used again for finning, optimizing resource efficiency.
No need for helical grooves over the core tube, simplifying the production process.
Perfect for placing fins on very thin-walled tubes, particularly when using expensive alloys for the core tube, offering versatility and cost savings.
The tube is engineered to endure temperatures up to 130°C, without succumbing to atmospheric corrosion or thermal 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
Introducing the KL Footed Fin, also known as the Knurled L Footed Fin, a marvel of engineering and design.
The KL fin is a masterpiece in thermal performance, known for its intricate knurled design. This exceptional fin is widely recognized in the industry as the knurled L fin. Expertly crafted, this finned tube closely mirrors the Wrap-On fin, utilizing both the Wrap-On and Embedded techniques for superior performance. Ingeniously crafted, the fins are formed from strips meticulously prepared into an L shape, then artfully rolled into a taper to achieve a perfect curl. Precision-engineered, it is helically wound onto the tube in a seamless, continuous loop under tension, ensuring maximum efficiency. The innovative design ensures the tube is perfectly embraced by the fin for optimal heat transfer. Utilizing state-of-the-art technology, a spinning tool knurls the base tube. The fin's foot is expertly knurled into the base tube, creating an impeccable bond that enhances thermal performance.
When the correct fin strip is used, the feet of each fin align flawlessly, creating a tight, gap-free connection. This exceptional construction offers protection against corrosion, significantly extending the tube's lifespan. Similar to L fins, each end is meticulously secured, preventing any unwinding and ensuring reliability. KL-Foot tension wound finned tubes are a staple in metal applications, chosen for their unmatched performance. Designed to withstand extreme conditions, these tubes operate efficiently at temperatures up to 320°C (608°F).
Advantages abound:
Resilient against corrosion, offering longevity and durability.
Engineered to resist vibrations, ensuring consistent performance.
Capable of withstanding temperatures up to a remarkable 320°C (608°F).
Combining high thermal performance, stress resistance, and air corrosion protection, this product offers an unparalleled advantage.
Versatile and adaptable, the KL can seamlessly replace any form of finned tube.
Discover the LL-Foot Fin, or Overlapped L, a sophisticated solution for modern needs.
Crafted with precision, these fins are made from strips similar to the L type, but with a unique, carefully controlled double L shape for superior functionality. This innovative LL-Foot Fin is helically coiled onto the tube under tension, ensuring a secure fit. The design ensures the fin clings perfectly to the tube, with each fin elegantly overlapping the foot of the next, providing complete coverage. This meticulous construction ensures the tube is well-protected from corrosion, enhancing its durability. In corrosive environments, this tube is a cost-effective alternative to more expensive extruded fin types.
Securely fastened at each end, just like L fins, for reliability you can count on. The LL-type fin tube is designed to perform at temperatures up to 350°F (177°C) with ease.
