Discover an extensive array of finned tubes tailored to meet specific needs: choose from tension wound finned tubes, embedded finned tubes, and extruded finned tubes, each designed with precision for optimal performance.
Tension wound finned tubes are intricately crafted by meticulously winding a robust aluminum or copper strip around the tube, ensuring tight tension for superior durability. This innovative strip winding technology offers a spectrum of fin designs: from the standard L-Fin to the enhanced LL-Fin and the cutting-edge KL-Fin.
Embedded fins (G-Fins) boast an advanced design by inserting a high-quality aluminum or copper strip into a precision-engineered helical groove on the tube's exterior surface.
Tension wound, embedded, and extruded finned tubes serve as the cornerstone of efficient air coolers, finding versatile applications across numerous industries:
Power plant heat exchangers, including electric, nuclear, thermal, and geothermal facilities, rely on these finned tubes for enhanced efficiency.
Steam condensate systems benefit from the reliable performance of these robust tubes.
They play a pivotal role in the chemical and petrochemical industry, ensuring optimal heat transfer.
Food processing plants and cutting-edge refrigeration technology capitalize on their exceptional thermal management capabilities.
Industrial applications, from steel mills to incinerators and gas compression facilities, harness the power of these finned tubes.
L-Foot Finned Tube
Our L-footed finned tubing is a marvel of engineering, offering exceptional heat transfer efficiency at economically viable costs, especially in lower-temperature situations. Featuring a distinctive L-shaped design, these fins remain steadfast, adeptly withstanding both heat cycling and the rigors of high velocity air vibration.
Explore the versatility of the L-Foot Finned Tube, available in an array of fin configurations:
Knurled Fin - Experience the innovation of an interference fit fin, where mechanical knurling ensures seamless integration of fin material with the tube wall.
LL Fin - Achieve unparalleled coverage with the Double Overlap fin (Double LL), offering double strip thickness for comprehensive tube protection.
Perforated L Fin - Enhanced with 'tear drop' slits, this ingenious design disrupts airflow around the fin helix for superior performance.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Also recognized as Wrap-On Finned Tubes, these are the go-to solution for applications with temperatures up to 300 degrees Fahrenheit, ensuring protection without compromising functionality. Crafted from a thin aluminum fin strip, these tubes feature a helical wrap that's meticulously wound around the tube circumference for optimal efficiency. The process begins with forming a 'foot' on one side of the fin strip, lending the tube its iconic L-Foot name. Subsequently, the strip is wound with precision, with the foot ensuring continuous contact with the tube's surface. Each L's short horizontal limb securely adheres to the base-tube surface, ensuring complete coverage and effective heat transfer. The tension generated in the fin strip during the wrapping process ensures a secure fit, maintaining the fin's position for long-lasting performance. L-footed finned tubing excels in maximizing heat transfer, particularly in scenarios involving low temperatures. The innovative L-shaped structure ensures the fins are robust against the challenges of heat cycling and high-speed air vibrations. This fin design also provides a measure of atmospheric protection, guarding against potential corrosion of the tube wall. The extensive contact area between the tube and the fin significantly amplifies heat transfer capabilities. Balancing efficiency with cost, this fin design stands out for its exceptional thermal performance.
To maintain the integrity of the aluminum fin and ensure it remains tightly bound, the fin ends are strategically stapled, preventing any loosening. This component is absolutely essential to the efficient operation of the air cooler, as it facilitates the crucial transfer of heat from the robust tube wall, through the precision-engineered fin, and out into the ambient air, ensuring optimal performance.
Advantages:
Perfectly suitable for low-temperature applications, offering reliable performance even in challenging conditions.
This finning type is celebrated as the most cost-effective method available, providing exceptional value compared to alternative techniques.
Failed fins can be effortlessly removed during production, allowing the bare tube to be reused for finning, enhancing sustainability and reducing waste.
No necessity for creating a helical groove over the core tube, simplifying the manufacturing process and reducing costs.
Fins can be expertly placed on a very thin-walled tube, which is particularly advantageous when using premium alloys as the core tube material.
The tube is engineered to withstand temperatures up to 130°C without incurring atmospheric corrosion or thermal stress, ensuring longevity and reliability.
Application:
Ideal for oil and gas refineries, enhancing cooling efficiency and operational reliability.
Widely employed in petroleum, chemical, and petrochemical industries for superior cooling solutions.
Perfect for natural gas treatment facilities, ensuring optimal cooling performance.
Integral to the steel making industry, offering robust cooling under high-demand conditions.
Critical for power plants, ensuring efficient heat exchange and dependable operation.
Used extensively in air conditioning applications for effective thermal management.
Essential for compressor coolers, providing enhanced cooling capabilities.
KL Footed Fin / Knurled L Footed Fin
The KL fin is also recognized as the knurled L fin, renowned for its superior bonding and thermal efficiency. This finned tube closely resembles the Wrap-On fin and is crafted using both Wrap-On and Embedded techniques, offering a versatile solution. Fins are precisely made from strips shaped into an L form, then meticulously rolled into a taper that elegantly curls. They are then helically wound onto the tube in an unbroken loop under tension for secure attachment. The fin embraces the tube tightly, ensuring maximum contact and efficiency. A specialized spinning tool knurls the base tube, and the fin's foot is seamlessly integrated into this knurling, resulting in a secure bond and improved thermal performance.
Utilizing the correct fin strip ensures one fin's foot seamlessly aligns with the next, leaving no gaps, enhancing protection and performance. This configuration provides added protection against corrosion, significantly extending the tube's lifespan. Like L fins, these fins are securely attached at each end to prevent unwinding, ensuring consistent performance. In metal applications, KL Foot tension wound finned tubes are widely used for their durability and performance. Capable of withstanding high temperatures up to 320°C (608°F), ensuring reliability in extreme conditions.
Advantages:
Corrosion-resistant Tubes provide long-lasting durability and reliability.
Impressive vibration resistance ensures stability and longevity.
Able to endure temperatures as high as 320°C (608°F), making it a versatile choice for demanding environments.
High thermal performance with outstanding stress resistance and air corrosion protection, creating an unmatched combination.
KL fins can replace any form of finned tube, offering unparalleled versatility.
LL-Foot Fin / Overlapped L
Fins are crafted similarly to the L type but feature a precisely designed stepped double L shape, rolled to create a graceful curl. The LL-Foot Fin - Overlapped L is then intricately coiled onto a tube under tension for a snug fit. The fin grips the tube securely, with each fin overhanging the next for complete coverage and maximum efficiency. This design ensures the tube is thoroughly protected from corrosion, enhancing its lifespan and performance. In environments where corrosion is a concern, the Robust G Type Embedded Finned Tube stands out as a cost-effective alternative to the pricier extruded finned tubes. This innovative design ensures durability and efficiency without breaking the bank.
The fin attachment process is meticulously designed, ensuring that fins are securely fastened at each end with the same reliable method used for L fins. This guarantees stability and optimal heat transfer performance. Crafted for resilience, the LL-type fin tube demonstrates its strength by performing seamlessly at temperatures soaring up to 350 degrees Fahrenheit (177°C). Its efficiency and reliability make it an indispensable component in high-temperature operations.
