Discover the unrivaled variety of finned tubes we offer, including tension wound finned tubes, embedded finned tubes, and extruded finned tubes, each crafted for excellence.
Tension wound finned tubes are meticulously crafted by winding a robust strip made of either aluminium or copper around the tube under strategic tension, ensuring superior performance. Our strip winding technology is versatile, producing a range of fins such as L-Fin, LL-Fin, and KL-Fin, tailored to meet diverse cooling needs.
Embedded fins (G-Fins) are expertly formed by winding aluminium or copper strip into a helical groove precisely machined on the tube's outer surface, guaranteeing optimal heat exchange.
Our finned tubes, whether tension wound, embedded, or extruded, serve as essential components in air coolers, ideal for a variety of industries:
Heat exchangers in power plants, spanning electric, nuclear, thermal, and geothermal, benefit from our cutting-edge finned tubes.
Efficient steam condensate systems
Chemical and petrochemical industries, where precision and reliability are paramount.
Food processing plants and advanced refrigeration technology applications.
Industrial settings like steel mills, incinerators, and gas compression facilities.
L-Foot Finned Tube
Maximize heat transfer with our highly efficient yet cost-effective L-footed finned tubing, perfect for lower temperature applications. The distinctive L-shaped design ensures fins remain rigid, resistant to heat cycling and high-velocity air vibration.
We offer the L-Foot Finned Tube in several innovative variations:
Knurled Fin - This interference fit type fin features mechanical knurling, enhancing the bond between the fin material and tube wall surface.
LL Fin - Double Overlap fin, known as Double LL, offers comprehensive double strip thickness coverage of the base tube.
Perforated L Fin - This advanced fin design introduces 'tear drop' slits that disrupt air flow, enhancing performance.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Also recognized as Wrap-On Finned Tubes, these are ideal for applications with temperatures not exceeding 300 degrees Fahrenheit, offering essential tube wall protection. These tubes feature a thin aluminium fin strip meticulously wound helically around the tube for maximum efficiency. The fin strip is initially formed with a 'foot' on one side, creating the signature L-Foot. This strip is tightly wound around the tube, ensuring the foot makes strong contact with the tube's outer surface. The short horizontal section of each L provides complete coverage of the base-tube surface. Tension in the fin strip during wrapping ensures the fin foot is forcefully seated and firmly secured. L-footed finned tubing maximizes heat transfer efficiently at lower temperatures. Its unique L-shaped design maintains rigidity, effectively resisting heat cycling and high-velocity air vibration. This design offers a protective barrier against atmospheric corrosion, safeguarding the tube wall. The extensive contact surface between the tube and fins significantly boosts heat transfer capabilities. This fin design stands out as both highly efficient and cost-effective, making it a smart choice.
Fins are securely stapled at the ends to prevent unravelling, maintaining consistent contact between the fin foot and the tube. This integral contact point is paramount to the efficiency and seamless operation of the air cooler. The transfer of heat journey commences from the sturdy tube wall, travels elegantly through the fin, and merges into the surrounding ambient air, ensuring optimal cooling performance.
Advantages:
Ideal for low-temperature applications, designed to perform flawlessly under cooler conditions.
Among the various options available, this finning type stands out as the most economically viable method, delivering exceptional value without compromising on quality.
Experience remarkable convenience as failed fins are effortlessly detachable during production, allowing the bare tube to be seamlessly reused for new finning applications, enhancing sustainability and efficiency.
Eliminate the need for any helical groove over the core tube, simplifying the process while maintaining structural integrity.
The versatility to place fins on an ultra-thin-walled tube is especially advantageous when utilizing costly alloys as the core tube, maximizing cost-effectiveness without sacrificing performance.
Engineered to endure temperatures soaring up to 130°C, this tube fears no atmospheric corrosion or thermal stress, promising enduring reliability.
Application:
Oil and gas refineries, the lifeblood of the energy sector.
Petroleum, chemical, and petrochemical industries, driving innovation and development.
Natural gas treatment, ensuring purity and efficiency.
Steel making industry, forging strength and durability.
Power plants, where energy generation meets sustainability.
Air conditioning, providing ultimate comfort and climate control.
Compressor coolers, enhancing machine performance and longevity.
KL Footed Fin / Knurled L Footed Fin
The KL fin is affectionately known as the knurled L fin, a nod to its distinctive features. This finned tube is nearly a twin to the Wrap-On fin, crafted with a harmonious blend of Wrap-On and Embedded techniques for superior application. Crafted from strips meticulously shaped into an L form akin to the L type, these fins are then elegantly rolled into a taper that encourages a natural curl. Once helically wound onto the tube in an uninterrupted loop under tension, the fin secures its place, promising unwavering performance. The tube enjoys a warm embrace from the fin, ensuring a snug fit. A spinning tool expertly knurls the base tube, allowing the foot of the fin to nestle into the knurling, creating an unbreakable bond with enhanced thermal conductivity.
When the correct fin strip is utilized, each fin seamlessly meets the next without interruption, ensuring a continuous protective layer. This meticulous design approach provides an enhanced shield against corrosion, prolonging the tube's lifespan. Parallel to L fins, these fins are anchored at each end, preventing any unwinding, thus maintaining structural integrity. For metal applications, KL-Foot tension wound finned tubes are the go-to choice, offering unparalleled reliability. Capable of withstanding an impressive maximum operating temperature of up to 320°C (608°F), this technology meets the demands of intense environments.
Advantages:
Corrosion-resistant Tubes, enduring the test of time and elements.
Built with vibration resistance, ensuring stability and longevity in dynamic environments.
Engineered to endure temperatures reaching up to 320°C (608°F), this tube is robust and reliable.
A unique trifecta of superior thermal performance, stress resilience, and air corrosion protection makes this product stand out.
Versatile and adaptable, KL fins can replace any form of finned tube, offering unmatched flexibility.
LL-Foot Fin / Overlapped L
Crafted with precision, the fins emerge from strips in a manner akin to the L type, but with a meticulously controlled stepped double L shape, rolled into a taper that allows for graceful curling. The LL-Foot Fin - Overlapped L is then intricately coiled onto a tube under precise tension, ensuring a secure fit. The fin clasps the tube tightly, with one fin elegantly overhanging the foot of the next, ensuring complete coverage of the base tube. This robust design guarantees exceptional protection against corrosion for the tube, enhancing its durability. In environments where corrosion is a concern, this innovative tube serves as a cost-effective alternative to the pricier extruded type fin, ensuring durability and functionality without compromise.
The fins are meticulously secured at both ends using the same trusted method employed for L fins, ensuring optimal performance and reliability. Engineered for excellence, the LL-type fin tube boasts impressive resilience, operating smoothly in temperatures soaring up to 350 degrees Fahrenheit (177 degrees Celsius).
