Discover our diverse range of finned tubes that cater to your every need: from tension wound finned tubes to embedded and extruded finned tubes, each designed to ensure ultimate performance.
Tension wound finned tubes are crafted with precision by winding a strip of either aluminium or copper around the tube under tension, offering an innovative solution to enhance efficiency. Our advanced strip winding technology delivers various fin types: L-Fin, LL-Fin, KL-Fin, each tailored for specific applications and optimized for superior heat transfer.
Embedded fins (G-Fins) are ingeniously created by embedding aluminium or copper strips into helically machined grooves on the tube's outer surface, ensuring robust durability and excellent thermal performance.
Our tension wound finned tubes, embedded finned tubes, and extruded finned tubes are essential for air coolers, with widespread applications including:
Heat exchangers for power plants (electric, nuclear, thermal, and geothermal), showcasing enhanced efficiency and reliability.
Sophisticated steam condensate systems that demand high-performance components.
Chemical and petrochemical industry, where precision and durability are paramount.
Food processing plants and refrigeration technology, necessitating hygienic and effective heat exchange solutions.
Industrial applications (steel mills, incinerators, gas compression facilities) that require robust and reliable heat transfer solutions.
L-Foot Finned Tube
Our L-footed finned tubing is a hallmark of efficiency and cost-effectiveness, delivering maximum heat transfer capabilities, even at lower temperatures. The distinctive L-shaped design ensures that fins remain securely in place, able to withstand heat cycling and high-velocity air vibration with ease.
We offer the L-Foot Finned Tube in a variety of innovative fin options:
Knurled Fin - A unique interference fit fin with mechanically knurled fin material, ensuring a firm bond to the tube wall surface.
LL Fin - Featuring a Double Overlap design, the LL fin provides comprehensive base tube coverage for enhanced durability.
Perforated L Fin - Designed with 'tear drop' slits that punctuate the helix, this innovation disrupts airflow for improved thermal performance.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes also known as Wrap-On Finned Tubes, are ideal for low-temperature applications up to 300°F, where they offer vital tube wall protection. These tubes feature a thin aluminium fin strip wound helically around the tube, delivering a perfect balance of efficiency and protection. A 'foot' is meticulously formed on the fin strip, lending the product its name, L-Foot. The strip is wound tightly, with the foot gripping the tube's outer surface, ensuring a dependable and steadfast fit. Each L's short limb firmly contacts the base-tube surface, fully enveloping it for optimal heat transfer. Tension in the wound fin strip enhances the seating of the fin foot, ensuring a secure and resilient attachment. L-footed finned tubing excels in delivering maximum heat transfer even at lower operating temperatures. The remarkable L-shaped design fortifies the fins, enabling them to endure the rigors of heat cycling and high-velocity air vibration. This design provides reliable atmospheric protection for the tube wall, guarding against corrosion. Extensive contact between the tube and fins significantly boosts heat transfer efficiency. Our fin design is not only highly efficient but also remarkably cost-effective, making it a prudent choice for diverse applications.
To prevent unravelling and ensure integrity, the fin ends are stapled, maintaining the crucial contact between the fin foot and tube. This pivotal contact in the air cooler's operation ensures effective heat transfer, as the heat seamlessly moves from the tube wall through the fin and into the surrounding ambient air, optimizing cooling efficiency.
Advantages:
Perfectly tailored for low-temperature applications, ensuring reliability and efficiency.
This finning type stands out as the most economical choice, offering unmatched cost-effectiveness compared to other methods.
Easy removal of failed fins during production, allowing the bare tube to be effortlessly reused for finning, enhancing sustainability.
No need to create a helical groove on the core tube, simplifying the production process.
Allows fin placement on extremely thin-walled tubes, highly advantageous when using costly alloys as core tubes, ensuring cost savings.
The tube can endure temperatures of up to 130°C, mitigating risks of atmospheric corrosion or thermal stress, ensuring longevity.
Application:
Ideal for oil and gas refineries, bolstering operational efficiency.
Utilized extensively in the petroleum, chemical, and petrochemical industries, enhancing process reliability.
Crucial for natural gas treatment processes, optimizing performance.
Essential in the steel-making industry, contributing to improved thermal management.
Widely used in power plants, aiding in efficient energy production.
Critical for air conditioning systems, enhancing cooling performance.
Optimizes compressor coolers, improving overall thermal efficiency.
KL Footed Fin / Knurled L Footed Fin
The KL fin is popularly known as the knurled L fin, offering distinct features. This finned tube, closely resembling the Wrap-On fin, is expertly crafted using a blend of both Wrap-On and Embedded techniques. The fins are fashioned from strips prepared into an L shape, similar to the L type, and then rolled into a taper, causing them to curl elegantly. Subsequently, it is helically wound onto the tube in a seamless continuous loop under tension. The fin closely embraces the tube, ensuring a secure fit. A spinning tool intricately knurls the base tube, allowing the fin's foot to lock firmly into the knurling, creating a robust bond with enhanced thermal performance.
Utilizing the correct fin strip ensures the foot of one fin snugly meets the next, eliminating any gaps between fins. This meticulous design helps shield the tube from corrosion, extending its service life. Similar to L fins, each end of the fins is securely attached to avert unwinding, ensuring stability. KL-Foot tension wound finned tubes are typically favored in metal-related applications for their superior performance. Accommodates up to a remarkable 320°C (608°F) maximum operating temperature, ensuring optimal operation.
Advantages:
Corrosion-resistant Tubes, maintaining integrity in harsh conditions.
Engineered for vibration resistance, ensuring durability during operations.
Capable of withstanding temperatures soaring up to 320°C (608°F), ensuring robust performance.
An extraordinary combination of high thermal performance, superior stress resistance, and protection from air corrosion.
KL fins can replace any form of finned tube, offering versatile solutions.
LL-Foot Fin / Overlapped L
Similar to the L type, these fins are crafted from strips, with the foot precisely formed into a stepped double L shape, rolled into a taper allowing for an elegant curl. The LL-Foot Fin - Overlapped L is then meticulously coil-wound onto the tube under tension, ensuring a snug fit. The fin adheres closely to the tube, with each fin overextending the foot of the next, ensuring complete base tube coverage. This design offers exceptional protection against corrosion, extending the tube's lifespan. In corrosive environments, this tube style is frequently chosen as a cost-effective alternative to the more expensive extruded type fin.
Crafted with precision and care, the fins are meticulously secured at each end, mirroring the reliable method employed for L fins. This ensures optimal durability and performance, making them a superior choice for your cooling needs. Designed for excellence, the LL-type fin tube is engineered to withstand temperatures soaring up to 350 degrees Fahrenheit (177°C). Ideal for high-performance applications, it promises efficient heat transfer and uncompromised reliability in challenging environments.
