L-Foot Finned Tube
Discover the ultimate balance of efficiency and cost-effectiveness with our L-footed finned tubing. Offering unparalleled heat transfer capabilities at lower temperatures, this product stands out as a leader in its class. Engineered with a distinctive L-shaped design, these fins are securely fastened to endure rigorous heat cycling and high-velocity air vibrations, ensuring long-lasting performance.
The L-Foot Finned Tube can be customized with these innovative fin variations:
Knurled Fin - Engineered with an interference fit, this fin features mechanical knurling that ensures a secure bond between the fin material and the tube wall.
LL Fin - Featuring a Double Overlap design, this fin offers double strip thickness coverage, providing comprehensive protection for the base tube.
Perforated L Fin - Enhanced with 'tear drop' slits around the helix, this design disrupts air flow for improved efficiency.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Also recognized as Wrap-On Finned Tubes, these are perfect for applications below 300°F, providing essential tube wall protection in low-temperature environments. Our L-Foot tension wound finned tubes consist of delicate aluminium fin strips expertly wound helically around the tube, forming a robust connection. A 'foot' is meticulously crafted on one side of the fin strip, giving rise to its name, L-Foot. The expertly wound strip tightly embraces the tube, with the foot firmly anchored on the tube's outer surface. The short horizontal limb of each L remains in constant contact with the base-tube surface, ensuring full coverage. The tension in the fin strip as it's wrapped around the tube ensures the fin foot is seated firmly, maintaining a steadfast hold. Offering maximum heat transfer at reduced temperatures, L-footed finned tubing is a high-performance solution for modern industries. Designed with finesse, the unique L-shape holds the fins rigidly, resisting both heat cycling and high-velocity air vibrations. This fin provides considerable atmospheric protection for the tube wall against corrosion, enhancing durability. The expansive contact surface between the tube and the finning optimizes heat transfer efficiency. This innovative fin design ensures both superior efficiency and cost-effectiveness.
The fin ends are securely stapled to prevent the aluminium fin from unraveling, ensuring continuous contact between the fin foot and the tube. This crucial contact is vital for air cooler functionality, facilitating seamless heat transfer from the tube wall through the fin to the ambient air.
Advantages:
Tailored for low-temperature applications
Among the most cost-effective finning methods available, providing great value.
Easily replace failed fins during production, allowing the reuse of bare tubes for new finning.
Eliminates the need for helical grooves on the core tube, simplifying production.
Allows fin placement on very thin-walled tubes, ideal when using expensive alloys as the core material.
Can withstand temperatures up to 130°C, mitigating risks of atmospheric corrosion or thermal stress.
Application:
Oil and gas refineries
Petroleum, chemical, and petrochemical industries
Natural gas treatment
Steel manufacturing industry
Power generation plants
Air conditioning systems
Compressor coolers
Introducing the KL Footed Fin, also known as Knurled L Footed Fin—a pinnacle of precision and innovation in finned tube technology, brought to you by Cangzhou Datang Steel Pipe Co., Ltd.
The revolutionary KL fin, a true testament to impeccable engineering, showcases unparalleled efficiency and performance. Renowned as the knurled L fin, this component epitomizes advanced design and superior durability. This finned tube, mirroring the Wrap-On fin, is expertly crafted using cutting-edge Wrap-On and Embedded techniques, ensuring optimal performance. Crafted from meticulously prepared strips, these fins form an L shape akin to the traditional L type before being elegantly rolled into a taper, resulting in an aesthetically pleasing curl. Each fin is helically wound onto the tube in a seamless, continuous loop under optimal tension, ensuring consistent contact and efficiency. The embrace of the fin around the tube is both snug and securing, creating a perfect union. The base tube undergoes expert knurling by a precision spinning tool, allowing the foot of the fin to interlock perfectly with the knurling, achieving an unyielding bond and superior thermal efficiency.
When utilizing the correct fin strip, the foot of each fin aligns impeccably with the next, leaving no gaps and enhancing the assembly’s integrity. This meticulous design guards the tube against corrosive elements, extending its life and maintaining its efficacy. Similar to the classic L fins, the ends are securely anchored to eliminate unwinding, ensuring durability. KL-Foot tension wound finned tubes are the go-to choice in metal applications, offering unrivaled reliability and performance. These tubes excel under challenging conditions, enduring up to an impressive 320°C (608°F), a testament to their robust design.
Advantages:
Tubing with unparalleled corrosion resistance, engineered to last.
Built-in vibration resistance, enhancing stability and endurance.
Engineered to withstand heat up to a remarkable 320°C (608°F) without compromising integrity.
A unique fusion of high thermal efficiency and stress resilience, paired with protection from air corrosion—a compelling combination.
KL fins can effortlessly replace any finned tube type, offering versatile and adaptable solutions.
LL-Foot Fin / Overlapped L
With precision akin to the L type, these fins are crafted from strips, with the foot fashioned into a sophisticated stepped double L shape, culminating in a graceful curl. The LL-Foot Fin - Overlapped L is meticulously helically coiled onto the tube under optimal tension, ensuring longevity and efficiency. The fin clings to the tube with precision, each fin elegantly overhanging the next, resulting in comprehensive tube coverage. This meticulous design ensures exceptional protection against corrosion, preserving the tube’s functionality in harsh environments. In corrosive environments, this tube serves as a cost-effective alternative to the pricier extruded fin types, without compromising on performance.
Fins are secured at both ends with the precision found in L fins, ensuring stability and resilience. Ideal for applications up to 350 degrees Fahrenheit (177°C), the LL-type fin tube stands as a testament to durability and reliability.
