Explore our versatile range of finned tubes: tension wound, embedded, and extruded, each tailored for distinct cooling solutions.
Tension wound finned tubes are expertly crafted by winding aluminum or copper strips around the core tube under precise tension for optimal performance. Our advanced strip winding technology creates various fin types: L-Fin, LL-Fin, and KL-Fin, each uniquely designed for specific applications.
Embedded fins (G-Fins) are meticulously crafted by winding aluminum or copper strips into a precision-machined helical groove on the tube's exterior, ensuring maximum efficiency.
Essential for air coolers, our tension wound, embedded, and extruded finned tubes excel in diverse applications such as:
Heat exchangers for power plants (electric, nuclear, thermal, and geothermal), offering outstanding energy efficiency.
Steam condensate systems, optimized for superior thermal management.
Chemical and petrochemical industry, ensuring robust and reliable cooling solutions.
Food processing plants and cutting-edge refrigeration technology, maintaining optimal temperatures seamlessly.
Industrial sectors (steel mills, incinerators, gas compression facilities), providing durable and efficient thermal solutions.
L-Foot Finned Tube
This highly efficient yet economical L-footed finned tubing maximizes heat transfer at reduced temperatures, offering unparalleled performance. The innovative L-shaped configuration ensures fins remain secure, enduring heat cycling and high-velocity air vibrations effectively.
We offer the L-Foot Finned Tube in these enhanced fin variations:
Knurled Fin - An interference fit type fin, meticulously knurled to create a mechanical bond with the tube's surface.
LL Fin - Featuring double overlap coverage, this LL fin provides comprehensive protection with dual strip thickness around the base tube.
Perforated L Fin - Enhanced with 'tear drop' slits along the helix, this design 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 applications where temperatures remain below 300°F, ensuring enhanced tube wall protection. These tubes are crafted by tightly winding a thin aluminum fin strip helically around the tube, ensuring lasting contact and efficacy. A distinctive 'foot' is formed on one fin strip side, lending the name L-Foot. The strip is wound snugly, with the foot firmly bearing against the tube's outer surface. Each L's short horizontal limb contacts the base tube surface fully, optimizing heat transfer. The tension in the fin strip during winding ensures the fin foot is forcefully seated, securing the fin in place. L-footed finned tubing enhances heat transfer efficiently at lower temperatures. The unique L-shape holds the fins firmly, withstanding both heat cycling and high-velocity air vibrations. This fin design provides a level of atmospheric protection, safeguarding the tube wall against corrosion. The extensive contact area between the tube and finning significantly boosts heat transfer. Offering high efficiency at an economical cost, this fin design is a testament to innovative engineering.
Fins are securely stapled at the ends to prevent unraveling, ensuring sustained contact between the fin foot and the tube. This contact is the heartbeat of the air cooler's operation. It ensures efficient heat transfer from the tube wall, through the fin, and into the surrounding ambient air, orchestrating a seamless thermal exchange.
Advantages:
Perfectly engineered for low-temperature applications, offering unmatched adaptability.
The finning type stands out as the most cost-effective method, surpassing other alternatives with its economic benefits.
In the event of fin failure, the faulty fins can be effortlessly removed during production, allowing the bare tube to be refinned and reused, enhancing sustainability.
No need to carve a helical groove over the core tube, simplifying the manufacturing process and maintaining structural integrity.
Fins can be precisely placed on a very thin-walled tube, a highly desirable feature when utilizing expensive alloys as the core tube, fostering material efficiency.
The tube boasts an impressive tolerance, withstanding up to 130°C, ensuring robust resistance against atmospheric corrosion and thermal stress.
Application:
Widely utilized in oil and gas refineries, optimizing cooling processes and enhancing efficiency.
A staple in petroleum, chemical, and petrochemical industries, delivering performance and reliability.
Integral for natural gas treatment, ensuring effective processing and cooling.
Essential in the steel-making industry, supporting high-temperature operations with ease.
Power plants rely on this innovation to maintain optimal cooling and thermal management.
Air conditioning systems benefit from enhanced cooling efficiency and reliability.
Compressor coolers leverage its superior cooling capabilities for optimal performance.
KL Footed Fin / Knurled L Footed Fin
The KL fin is famously known as the knurled L fin, celebrated for its distinctive design. This finned tube mirrors the Wrap-On fin, crafted using both Wrap-On and Embedded techniques, offering versatile design options. Crafted from strips prepared into an L shape, comparable to the L type, cleverly rolled into a taper that encourages curling. Ingeniously helically wound onto the tube in a continuous loop under tension, ensuring a secure fit. The fin embraces the tube with a snug fit, maximizing thermal efficiency. A spinning tool skillfully knurls the base tube, with the fin's foot knurled in, creating a tight bond for enhanced thermal performance.
When using the correct fin strip, each fin's foot aligns perfectly, leaving no space between fins, reinforcing protection. This meticulous design shields the tube from corrosion, significantly extending its lifespan. Similar to L fins, these fins are firmly attached at each end, preventing unwinding and maintaining stability. In metal-involved applications, KL-Foot tension wound finned tubes are the preferred choice, delivering reliable performance. Handles up to a remarkable 320°C (608°F) maximum operating temperature, showcasing exceptional resilience.
Advantages:
Corrosion-resistant Tubes designed for the toughest environments, ensuring lasting durability.
Vibrational resistance ensures steady performance even in dynamic conditions.
Engineered to endure temperatures reaching 320°C (608°F), standing strong under extreme conditions.
Offers a unique blend of high thermal performance, stress resistance, and protection from air corrosion, setting it apart.
KL can seamlessly replace any form of finned tube, offering versatile adaptability.
LL-Foot Fin / Overlapped L
Crafted from strips in a similar fashion to the L type, but with a meticulously controlled stepped double L shape, rolled to curl with precision. The LL-Foot Fin - Overlapped L is helically coiled onto a tube under tension, ensuring a secure installation. The fin clings securely to the tube, with one fin gracefully overhanging the foot of the next, ensuring complete coverage and protection. This design excellently shields the tube from corrosion, enhancing its longevity and performance. In environments prone to corrosion, this specialized tube emerges as a cost-effective alternative to the pricier extruded fin type, offering remarkable resilience and performance.
The fins are expertly secured at each end, mirroring the reliable method used for L fins, ensuring stability and efficiency. The LL-type fin tube is designed to withstand temperatures reaching up to 350 degrees Fahrenheit (177°C), delivering exceptional performance in high-temperature applications.
