We offer a diverse range of finned tubes, including tension wound finned tubes, embedded finned tubes, and extruded finned tubes to cater to various cooling needs.
Tension wound finned tubes are ingeniously crafted by winding a high-quality strip made of either aluminium or copper around the tube under a controlled tension. Our advanced strip winding technology allows the creation of distinct types of fins: L-Fin, LL-Fin, and KL-Fin, each designed for specific performance requirements.
Embedded fins (G-Fins) are precisely manufactured by expertly winding an aluminium or copper strip into a helical groove that is meticulously machined on the tube's outer surface.
Our tension wound, embedded, and extruded finned tubes are essential components for air coolers, widely utilized in a variety of application fields such as:
Heat exchangers for power plants, including electric, nuclear, thermal, and geothermal power facilities.
Efficient steam condensate systems.
The demanding chemical and petrochemical industry.
Food processing plants and innovative refrigeration technology.
Various industrial applications such as steel mills, incinerators, and gas compression facilities.
L-Foot Finned Tube
The highly efficient yet cost-effective L-footed finned tubing is designed to offer maximum heat transfer even at lower temperatures. Featuring a unique L-shaped design, it ensures fins remain rigid, effectively withstanding heat cycling and high-velocity air vibrations.
The L-Foot Finned Tube is available in various fin variations including:
Knurled Fin - This is an interference fit type fin, featuring mechanical knurling of the fin material to enhance its bond to the tube wall surface.
LL Fin - The Double Overlap fin (Double LL) offers comprehensive coverage, providing double strip thickness over the entire base tube.
Perforated L Fin - An innovative enhancement, it incorporates 'tear drop' slits around the helix to effectively disrupt air flow.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Also known as Wrap-On Finned Tubes, these are ideal for applications where temperatures remain below 300 degrees Fahrenheit, providing low-temperature functionality with some tube wall protection. Constructed with a thin aluminium fin strip tightly wound helically around the tube circumference, L-Foot tension wound finned tubes offer unparalleled performance. The term 'foot' refers to the initial shaping of a side of the fin strip, leading to the name L-Foot. The strip is meticulously wound around the tube, with the foot making secure contact on the tube's outer surface. Each L's short horizontal limb is in full contact with the base-tube surface, ensuring comprehensive coverage. The tension in the fin strip as it wraps around the tube is crucial, securing the fin foot powerfully against the tube and keeping the fin firmly in place. L-footed finned tubing delivers optimal heat transfer at reduced temperatures. The signature L-shaped design holds fins firmly, effectively resisting heat cycling and high-velocity air vibrations. This design also provides substantial atmospheric protection against corrosion, safeguarding the tube wall. The extensive contact surface between the tube and the fin aids in superior heat transfer. This innovative fin design is not only highly efficient but also remarkably cost-effective.
To ensure longevity, the ends of the fins are stapled to prevent the aluminium fin from unravelling, maintaining the vital contact between the fin foot and the tube. This pivotal contact is the heart of the air cooler's operation, facilitating the seamless transfer of heat from the tube wall, through the fin, and into the surrounding ambient air, ensuring optimal efficiency.
Advantages:
Tailor-made for applications in low-temperature environments, ensuring reliability and performance.
This finning type stands as the most economically savvy method, delivering exceptional value.
Fins that fail can be effortlessly removed during production, allowing the bare tube to be reused for finning, enhancing sustainability.
There's no requirement to create a helical groove over the core tube, simplifying the process significantly.
Fins can be mounted on an ultra-thin-walled tube, a feature highly desirable when expensive alloys are employed as the core tube, ensuring cost-efficiency.
Designed to withstand temperatures up to 130°C, the tube resists atmospheric corrosion and thermal stress, ensuring longevity.
Application:
Widely used in oil and gas refineries for optimal performance.
Essential in petroleum, chemical, and petrochemical industries, offering unmatched reliability.
Proven effectiveness in natural gas treatment, ensuring high standards.
Valuable to the steel-making industry, enhancing operational efficiency.
Integral to power plants, supporting energy generation.
Key component in air conditioning systems, promoting effective cooling.
Crucial for compressor coolers, ensuring smooth operations.
KL Footed Fin / Knurled L Footed Fin
The KL fin is also known as the knurled L fin. This finned tube mirrors the Wrap-On fin, crafted using both Wrap-On and Embedded techniques for versatility. Crafted from strips prepared into an L shape similar to the L type, and then rolled into a taper to induce curling. Subsequently, it is helically wound onto the tube in a continuous loop under precise tension. The fin embraces the tube tightly, ensuring a secure fit. A spinning tool knurls the base tube, allowing the foot of the fin to integrate seamlessly, enhancing the thermal bond and performance.
Each fin's foot seamlessly aligns with the next when utilizing the precise fin strip, leaving no gaps between fins. This configuration provides robust protection against corrosion for the tube. Similar to L fins, the ends are secured to prevent unwinding, ensuring durability. In metal applications, KL-Foot tension wound finned tubes are the go-to choice for optimal performance. Can withstand a remarkable maximum operating temperature of up to 320°C (608°F), offering exceptional resilience.
Advantages:
Corrosion-resistant Tubes, offering long-lasting protection and durability.
Engineered for vibration resistance, ensuring stability and reliability.
Capable of withstanding extreme temperatures up to 320°C (608°F), ensuring performance and reliability.
Combines high thermal performance with stress resistance and air corrosion protection, a truly unique combination.
KL finned tubes are a versatile replacement for any finned tube type, offering adaptability and efficiency.
LL-Foot Fin / Overlapped L
Fins are crafted from strips akin to the L type, with a double L shaped foot design for enhanced fit, then rolled into a taper for curling. The LL-Foot Fin - Overlapped L is helically coiled onto a tube under tension, ensuring a snug fit. The fin tightly grips the tube, with each fin overlapping the foot of the next, fully covering the base tube. This configuration provides robust corrosion protection for the tube. Frequently used in corrosive environments, this tube offers a cost-effective alternative to pricier extruded type fins.
Our G Type Fin Tube features fins securely anchored at each end, employing a method similar to that of L fins, ensuring stability and efficiency in performance. The LL-type fin tube is expertly designed to withstand and perform optimally in environments with temperatures soaring up to 350 degrees Fahrenheit (177°C), making it an ideal choice for high-temperature applications.
