Discover our diverse range of finned tubes, including tension wound finned tubes, embedded finned tubes, and extruded finned tubes, all designed to meet your air cooling needs with precision and efficiency.
Tension wound finned tubes are meticulously crafted by expertly winding a strip made from premium aluminium or copper tightly around the tube, ensuring optimal tension and durability. Our strip winding technology offers a variety of fin styles to suit any requirement: L-Fin, LL-Fin, and KL-Fin, each designed to maximize performance.
Embedded fins (G-Fins) are created by intricately winding an aluminium or copper strip into a precision-engineered helical groove on the tube's outer surface, ensuring long-lasting performance.
Tension wound finned tubes, embedded finned tubes, and extruded finned tubes serve as essential components for air coolers across a variety of applications including:
Heat exchangers in power plants, be it electric, nuclear, thermal, or geothermal, benefit from our finned tubes' robust heat transfer capabilities.
Perfect for steam condensate systems, our finned tubes ensure efficiency and reliability.
Indispensable in the chemical and petrochemical industry, our products are designed to withstand demanding conditions.
Ideal for food processing plants and cutting-edge refrigeration technology, enhancing system performance and safety.
Reliable in industrial settings such as steel mills, incinerators, and gas compression facilities, offering superior performance under challenging circumstances.
L-Foot Finned Tube
L-footed finned tubing is engineered to be highly efficient and cost-effective, providing exceptional heat transfer capabilities even at lower temperatures. The ingenious L-shaped design secures fins firmly, allowing them to endure heat cycling as well as high-velocity air vibrations.
The L-Foot Finned Tube can be customized with the following fin variations to enhance performance:
Knurled Fin - This type features a unique interference fit with mechanical knurling, firmly bonding the fin material to the tube wall surface.
LL Fin - Featuring double overlap fin coverage, double LL offers robust double-strip thickness protection over the entire base tube.
Perforated L Fin - This design innovation introduces 'tear drop' slits around the helix to disrupt airflow, enhancing the fin's performance.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes also known as Wrap-On Finned Tubes, are tailored for applications where temperatures remain below approximately 300 degrees Fahrenheit, offering protection for low-temperature use. L-Foot tension wound finned tubes feature a thin aluminium fin strip intricately wound around the tube circumference for superior efficiency. A 'foot' is crafted on one side of the fin strip, giving rise to the name L-Foot, ensuring a secure fit. The strip is precisely wound around the tube, with the foot firmly pressing against the tube's outer surface for maximum contact. The short horizontal limb of each L thoroughly covers the base-tube surface, providing complete protection and efficiency. Tension while winding the fin strip around the tube ensures the fin foot is forcefully seated, securely holding the fin in position. L-footed finned tubing excels in maximizing heat transfer capabilities at lower temperatures. The innovative L-shaped configuration ensures fins remain rigid, withstanding both heat cycling and high-speed air vibrations. This fin design offers reliable atmospheric protection to the tube wall, safeguarding against corrosion. The extensive contact surface between the tube and fin enhances heat transfer efficiency significantly. This fin design is not only highly efficient but also remarkably cost-effective, offering great value.
To prevent the aluminium fin from unravelling, the ends are securely stapled, maintaining the vital contact between the fin foot and the tube. This contact is absolutely vital to the seamless operation of the air cooler, as it facilitates efficient heat transfer. The heat journey begins at the tube wall, moves through the fin, and finally dissipates into the surrounding ambient air.
Advantages:
Perfectly engineered for low-temperature applications, ensuring optimal functionality and efficiency.
The finning type is an economically savvy choice, offering unrivaled cost-effectiveness compared to other methods.
Should any fins fail, they can be effortlessly removed during the production process, allowing the bare tube to be reused for finning without hassle.
No cumbersome helical grooves are required on the core tube, simplifying the manufacturing process.
Fins can be expertly positioned on ultra-thin-walled tubes, a feature particularly advantageous when costly alloys are used as the core tube.
Our tube is robust, capable of withstanding temperatures of up to 130°C, all while resisting atmospheric corrosion and thermal stress, ensuring long-term reliability.
Application:
Oil and gas refineries serve as the perfect backdrop for our innovative solutions.
Designed for the demanding environments of the petroleum, chemical, and petrochemical industries, engineered for excellence.

KL Footed Fin / Knurled L Footed Fin
The KL fin also known as the knurled L fin, sets a new standard in performance. This finned tube, closely resembling the Wrap-On fin, is crafted using both Wrap-On and Embedded techniques, ensuring superior quality. Crafted from expertly prepared strips into an L shape, comparable to the L type, then elegantly rolled into a taper for a seamless curl. With precision, the fin is helically wound onto the tube in a continuous loop under tension, ensuring a snug fit. The fin embraces the tube tightly, maximizing thermal performance. A spinning tool knurls the base tube, securely embedding the foot of the fin into the knurling for an unbreakable bond and enhanced thermal efficiency.
When using the correct fin strip, the foot of one fin seamlessly abuts the next, leaving no gaps and ensuring optimal protection against corrosion. This meticulous design serves as a robust defense, safeguarding the tube against corrosion. Mirroring the technique of L fins, these fins are anchored at each end to prevent unwinding, maintaining structural integrity. In metal-involved applications, KL-Foot tension wound finned tubes are the preferred choice, offering unmatched reliability. Designed to withstand up to 320°C (608°F) maximum operating temperature, ensuring resilience in extreme conditions.
Advantages:
Corrosion-resistant Tubes ensure longevity and performance, even in harsh environments.
Exceptional vibration resistance promotes stability and reliability.
Engineered to endure temperatures soaring up to 320°C (608°F), maintaining integrity.
High thermal performance and stress resistance, paired with unmatched protection from air corrosion, offers a unique and powerful combination.
The KL fin can replace any form of finned tube, adding versatility to its robust performance.
LL-Foot Fin / Overlapped L
Crafted from meticulously prepared strips, similar to the L type, but the foot is uniquely crafted into a precision-controlled stepped double L shape, elegantly rolled into a taper. The LL-Foot Fin - Overlapped L is then helically coiled onto the tube under tension, ensuring a perfect fit. The fin clings tightly to the tube, with each fin seamlessly overlapping the next, providing corrosion protection by completely covering the base tube. The tube enjoys superior corrosion protection thanks to this innovative design. In corrosive environments, this form of tube is often chosen as a cost-effective alternative to the pricier extruded type fin, delivering performance without compromise.
The fins are meticulously secured at each end, offering a steadfast and reliable attachment, akin to the renowned L fins. This ensures optimal performance and longevity, even under demanding conditions. Exhibiting remarkable versatility, the LL-type fin tube is engineered to withstand temperatures soaring up to an impressive 350 degrees Fahrenheit (177°C), making it a robust choice for various thermal applications.
