Discover our diverse range of finned tubes, including tension wound finned tubes, embedded finned tubes, and extruded finned tubes, each designed to elevate your cooling systems' efficiency.
Our Tension Wound Finned Tubes are meticulously crafted by winding a strip of premium aluminium or copper around the tube under controlled tension, ensuring durability and performance. The innovative strip winding technology introduces a variety of fin types: L-Fin, LL-Fin, KL-Fin, each tailored to meet specific cooling needs.
Embedded Fins (G-Fins) These are expertly manufactured by winding aluminium or copper strips into a precision-engineered helical groove on the tube's outer surface, enhancing heat exchange capabilities.
Our range of tension wound finned tubes, embedded finned tubes, and extruded finned tubes are indispensable components for air coolers, serving a wide array of applications:
Efficient heat exchangers for power plants, including electric, nuclear, thermal, and geothermal, ensuring optimal performance in demanding environments.
Robust systems for steam condensate, designed to maintain operational integrity and efficiency.

L-Foot Finned Tube
Our L-footed finned tubing delivers exceptional heat transfer efficiency, even at lower temperatures, making it a cost-effective choice for your thermal requirements. Featuring a unique L-shaped design, it secures fins robustly to withstand heat cycling and high-velocity air vibration, ensuring long-term durability.
The L-Foot Finned Tube is available in various fin enhancements for tailored performance:
Knurled Fin - This fin type employs mechanical knurling for an interference fit, enhancing the bond between the fin material and the tube wall surface.
LL Fin - The Double Overlap fin (the Double LL) offers comprehensive base tube coverage with double strip thickness, amplifying durability and performance.
Perforated L Fin - This design innovation introduces 'tear drop' slits along the helix, effectively disrupting airflow for enhanced heat exchange.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Also referred to as Wrap-On Finned Tubes, these are ideal for low-temperature applications where temperatures remain below 300 degrees Fahrenheit, providing essential tube wall protection. These L-Foot tension wound finned tubes feature a helically wound aluminium fin strip, ensuring a precise fit around the tube's circumference. The 'foot' is ingeniously formed on one side of the fin strip, lending the L-Foot its distinctive name and function. Subsequently, the strip is tightly wound around the tube, with the foot securing firmly to the tube's outer surface. The short horizontal limb of each L contacts the base-tube surface, providing comprehensive coverage and enhancing heat transfer. The tension in the fin strip serves to forcefully seat the fin foot on the tube, maintaining a secure and lasting fit. L-footed finned tubing is engineered for optimal heat transfer at reduced temperatures, maximizing efficiency and reliability. The unique L-shaped design ensures robust fin retention, effectively resisting heat cycling and high-velocity air vibrations. This fin style offers notable atmospheric protection for the tube wall, safeguarding against corrosion. The extensive contact surface between the tube and the finning significantly boosts heat transfer efficiency. Designed to be highly efficient and economically viable, this fin design is your go-to solution for enhanced heat exchange.
The fin ends are meticulously stapled to prevent the aluminium fin from unraveling, ensuring consistent contact between the fin foot and the tube. This connection is absolutely vital to the seamless functioning of the air cooler, as it efficiently transfers heat from the tube wall, journeys through the fin, and ultimately disperses it into the ambient air environment.
Advantages:
Perfectly tailored for applications in low-temperature environments, ensuring optimal performance.
The finning type we offer stands as the most economical choice among available methods.
Even if fin failure occurs, the affected fins can be effortlessly removed during production, allowing the bare tube to be reused for new finning.
No need to create a helical groove on the core tube, simplifying the process.
Allows fins to be placed on an ultra-thin-walled tube, an especially appealing option when using costly alloys as the core tube.
The tube boasts resilience, enduring temperatures up to 130°C without succumbing to atmospheric corrosion or thermal stress.
Application:
Ideal for use in oil and gas refineries, offering robust performance.
Widely applicable in the petroleum, chemical, and petrochemical industries.
Perfect for the treatment of natural gas, improving process efficiency.
Essential for operations within the steel-making industry.
A key component in power plants, enhancing operational reliability.
Integral to air conditioning systems, ensuring efficient cooling.
Vital in compressor coolers, boosting performance and reliability.
KL Footed Fin / Knurled L Footed Fin
The KL fin is commonly referred to as the knurled L fin, a testament to its unique construction. This finned tube closely resembles the Wrap-On fin, crafted with a blend of both Wrap-On and Embedded techniques. Fins are crafted from strips shaped into an L form, similar to the L type, then rolled into a taper to induce curling. Subsequently, it is helically wound onto the tube in a seamless loop under continuous tension. The fin firmly embraces the tube, ensuring a tight and secure fit. A spinning tool knurls the base tube, allowing the fin's foot to integrate with the knurling, creating a superior bond and enhancing thermal performance.
When utilizing the correct fin strip, one fin's foot aligns snugly with the next, leaving no gaps between fins. This ensures the tube is shielded from corrosion. Much like L fins, the fin's ends are securely attached to prevent unwinding. In metal applications, the KL Foot tension wound finned tubes are frequently utilized. Capable of operating at a maximum temperature of 320°C (608°F), ensuring durability.
Advantages:
Tubes designed to resist corrosion, extending longevity and reliability.
Inherently resistant to vibration, maintaining structural integrity.
Built to tolerate temperatures as high as 320°C (608°F).
Combines high thermal performance and stress resistance with air corrosion protection, delivering a unique solution.
KL finned tubes can replace any existing finned tube variant.
LL-Foot Fin / Overlapped L
Fins are crafted from strips much like the L type, with the foot expertly formed into a stepped double L shape, rolled to taper and curl. The LL-Foot Fin - Overlapped L is then helically coiled onto the tube under tension, ensuring a secure fit. The fin tightly grasps the tube, with one fin's foot gracefully overlapping the next, completely covering the base tube. This results in exceptional protection against corrosion for the tube. In corrosive environments, this tube type is a cost-effective alternative to the pricier extruded type fin.
The innovative design of our Reliable G Type Fin Tube ensures that fins are meticulously secured at each end, following the dependable method employed for L fins. This guarantees a robust and durable performance in air cooling systems. The LL-type fin tube is engineered to withstand temperatures soaring up to 350 degrees Fahrenheit (177 degrees Celsius), making it an ideal choice for high-temperature applications. Its resilience under heat is a testament to its superior construction.
