Discover a world of advanced thermal solutions with our diverse array of finned tubes! Our offerings include tension wound finned tubes, embedded finned tubes, and extruded finned tubes, each engineered for optimal performance.
Tension wound finned tubes are masterfully crafted by winding a strip, made of premium aluminium or copper, around the tube under precise tension. Our strip winding technology unlocks a variety of specialized fins: L-Fin, LL-Fin, and the ingenious KL-Fin.
Embedded fins, also known as G-Fins are expertly produced by embedding an aluminium or copper strip into a helical groove machined on the outer surface of the tube.
These cutting-edge tension wound, embedded, and extruded finned tubes are the powerhouse behind air coolers, flourishing in diverse application fields such as:
Heat exchangers for mighty power plants, including electric, nuclear, thermal, and geothermal facilities
Sophisticated steam condensate systems
The dynamic realms of the chemical and petrochemical industry
Essential food processing plants and cutting-edge refrigeration technology
Versatile industrial applications, from steel mills to incinerators and gas compression facilities
Introducing the L-Foot Finned Tube,
a marvel of efficiency and cost-effectiveness, delivering unparalleled heat transfer at lower temperatures. Its distinctive L-shaped design holds fins securely, standing strong against heat cycling and high-velocity air vibrations.
Unleash the potential of the L-Foot Finned Tube with these innovative fin variations:
Knurled Fin - A robust interference fit type, with the fin material mechanically knurled to the tube wall surface for enhanced grip.
LL Fin - The Double Overlap fin (or double LL) provides an additional layer of security with double strip thickness coverage across the entire base tube.
Perforated L Fin - This ingenious enhancement creates 'tear-drop' slits along the helix, innovatively disrupting airflow for superior performance.
L-Foot Fin / Wrap-On Fin
Delve into the world of L-Foot Tension Wound Finned Tubes also known as Wrap-On Finned Tubes, perfect for applications where temperatures are modest, not exceeding around 300 degrees Fahrenheit. Ideal for low-temperature settings where tube wall protection is essential. These tubes showcase a slender aluminium fin strip, meticulously wound around the tube circumference in a helical pattern. The 'foot' is carefully crafted on one side of the fin strip, hence the name L-Foot. Once formed, the strip is wound tightly around the tube, with the foot ensuring a snug fit on the tube's outer surface. Every short horizontal limb of each L makes full contact with the base-tube surface, achieving complete coverage. The tension in the fin strip as it encircles the tube securely seats the fin foot, holding it firmly in place. L-footed finned tubing excels in providing maximum heat transfer at lower temperatures. The unique L-shaped design endows the fins with rigidity to withstand heat cycling and high-velocity air vibrations. This ingenious fin design also offers a degree of atmospheric protection for the tube wall, shielding it from corrosion. The extensive contact surface between the tube and the finning greatly enhances heat transfer efficiency. This design is not only highly efficient but also incredibly cost-effective.
To ensure durability, the ends of the fins are stapled to prevent the aluminium fin from unravelling and losing contact with the tube. The pivotal contact point within the air cooler's operation is where heat effortlessly journeys from the tube wall, across the fin, and seamlessly into the ambient air enveloping the system.
Advantages:
Engineered for optimal performance in low-temperature applications, ensuring reliable and efficient heat transfer.
Boasting the most economically efficient finning type available, making it a top choice in cost effectiveness when compared to other alternatives.
Should any fins fail during production, they can be swiftly and simply removed, allowing the bare tube to be reused for finning, enhancing sustainability.
Ingeniously designed, there is no necessity to carve a helical groove into the core tube, simplifying the fabrication process.
The remarkable design allows for fin placement on exceptionally thin-walled tubes, an especially advantageous feature when utilizing costly alloy materials as the core tube.
The robust tube construction is capable of withstanding temperatures soaring up to 130°C, all the while resisting atmospheric corrosion and thermal stress.
Application:
Oil and gas refineries - where reliability and efficiency are paramount.
Petroleum, chemical, and petrochemical industries - providing high-performance cooling solutions.
Natural gas treatment facilities - ensuring optimal operational temperatures.
Steel making industry - supporting high-demand cooling requirements.
Power plants - delivering excellent thermal management.
Air conditioning systems - enhancing cooling efficiency.
Compressor coolers - optimizing performance and longevity.
KL Footed Fin / Knurled L Footed Fin
The KL fin is alternatively recognized as the knurled L fin, offering robust performance and thermal efficiency. Nearly mirroring the Wrap-On fin, this finned tube is crafted using both the Wrap-On and Embedded methods for superior heat exchange. Fin strips are expertly shaped into an L form comparable to the L type, then meticulously rolled into a taper that allows for curling. They are subsequently helically wound onto the tube continuously under tension, ensuring a secure fit. The fin lovingly embraces the tube, ensuring consistent heat transfer and security. A sophisticated spinning tool knurls the base tube, with the fin's foot firmly embedded into the base tube's knurling, enhancing the bond and amplifying thermal performance.
When the appropriate fin strip is used, one fin's foot seamlessly aligns with the next, eliminating gaps and reinforcing protection from the elements. Such design precision helps defend the tube against corrosion, prolonging lifespan and performance. Similar to L fins, each fin end is meticulously attached, preventing any chance of unwinding over time and usage. Widely utilized in metal applications, KL-Foot tensioned wound finned tubes provide unmatched reliability and efficiency. Capable of enduring extreme conditions, with a maximum operational temperature reaching up to 320°C (608°F).
Advantages:
Corrosion-resistant Tubes - engineered to withstand harsh environments.
Designed with vibration resistance for stable and steady performance.
Formulated to endure high temperatures, reaching up to 320°C (608°F), without compromising integrity.
Combining high thermal performance and stress resistance with superior protection from air corrosion, this is an unprecedented solution.
Any type of traditional finned tube can be effortlessly substituted with KL for improved performance.
LL-Foot Fin / Overlapped L
Fin strips are crafted in a manner akin to the L type, only that the foot is engineered into a stepped double L formation, rolled into a taper for curling. The LL-Foot Fin - Overlapped L construction is then helically coiled around a tube under tension, ensuring a snug fit. With a secure grip, one fin overhangs onto the foot of the next, ensuring the base tube is entirely covered and protected. This meticulous design ensures the tube is well shielded from corrosion, offering longevity and durability. In corrosive environments, this tube style is frequently chosen as a cost-effective substitute to the pricier extruded fin type.
The fins are meticulously secured at each end with precision, employing the same dependable method as seen in L fins, ensuring durability and efficiency. The robust LL-type fin tube excels in environments with temperatures soaring up to an impressive 350 degrees Fahrenheit (177 degrees Celsius), delivering superior performance under heat-intensive conditions.
