We proudly present a comprehensive range of finned tubes: tension wound finned tubes, embedded finned tubes, and extruded finned tubes, each tailored to perfection.
Tension wound finned tubes are expertly crafted by meticulously winding a strip of either aluminium or copper around the tube under precise tension, ensuring durability. Our strip winding technology offers a variety of fin types: L-Fin, LL-Fin, and KL-Fin, each designed for specific performance enhancements.
Embedded fins (G-Fins) are crafted by skilfully winding an aluminium or copper strip into a helical groove machined on the tube's outer surface for optimal performance.
Tension wound, embedded, and extruded finned tubes are essential for air coolers, serving diverse applications such as:
Heat exchangers in power plants, spanning electric, nuclear, thermal, and geothermal sectors.
Steam condensate systems.
Chemical and petrochemical industries, meeting rigorous standards.
Food processing plants and cutting-edge refrigeration technologies.
Industrial sectors including steel mills, incinerators, and gas compression facilities.
L-Foot Finned Tube
Delivers exceptional efficiency and cost-effectiveness, offering maximum heat transfer at reduced temperatures. The ingenious L-shaped configuration ensures fins remain steadfast against heat cycling and high velocity air vibration.
The L-Foot Finned Tube is available with various fin enhancements such as:
Knurled Fin - This type features an interference fit, with mechanical knurling of the fin material to the tube wall surface for enhanced grip.
LL Fin - Double Overlap fin provides comprehensive double strip thickness coverage across the base tube.
Perforated L Fin - Innovatively crafted with "tear drop" slits around the helix, it disrupts airflow effectively.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes also referred to as Wrap-On Finned Tubes, specialize in low-temperature applications not surpassing 300°F, providing essential tube wall protection. These tubes feature an aluminium fin strip meticulously wound helically around the tube circumference for precision fit. A strategically formed "foot" on one side of the fin strip gives rise to the name L-Foot. The strip is tightly coiled around the tube, with the foot resting firmly against the tube's outer surface. The horizontal limb of each L makes full contact with the base-tube surface, ensuring complete coverage. The tension exerted as the fin strip wraps around the tube securely seats the fin foot and maintains a firm hold. L-footed finned tubing is engineered for maximum heat transfer efficiency at lower operational temperatures. Its unique L-shaped design allows fins to withstand heat cycling and high velocity air vibration, ensuring stability. This fin design provides protective shielding for the tube wall against corrosive atmospheric elements. The extensive contact area between the tube and finning significantly boosts heat transfer. Our fin design offers an unbeatable combination of high efficiency and cost-effectiveness.
To ensure longevity, the fin ends are stapled securely, preventing the aluminium fin from unravelling and maintaining optimal contact. This component plays a pivotal role in the air cooler's function. It facilitates efficient heat transfer from the tube wall, through the fin, and into the ambient air, ensuring optimal cooling performance.
Advantages:
Perfectly engineered for low-temperature applications for enhanced versatility.
Experience the most economical finning method available, providing cost savings without compromising performance.
Easily replace failed fins during production and reutilize bare tubes for subsequent finning, optimizing resources.
No requirement for creating a helical grove on the core tube, simplifying the manufacturing process.
Fins can be expertly placed on ultra-thin walled tubes, particularly beneficial when using high-value alloys as the core, maximizing material efficiency.
Engineered to endure temperatures up to 130°C with no risk of atmospheric corrosion or thermal stress, ensuring long-lasting durability.
Application:
Oil and gas refineries
Petroleum, chemical, and petrochemical industries
Natural gas processing and treatment facilities
Steel manufacturing industry
Power generation plants
Advanced air conditioning systems
Compressor cooling units
KL Footed Fin / Knurled L Footed Fin
The KL fin is also referred to as the renowned knurled L fin. This innovative finned tube closely resembles the Wrap-On fin, crafted using both Wrap-On and Embedded techniques for superior performance. Fin strips are meticulously formed into an L shape, akin to the L type, then rolled into a taper, inducing a curling effect for enhanced efficiency. It is expertly helically wound onto the tube in a continuous loop under tension, ensuring a snug fit. The fin embraces the tube seamlessly. A precision spinning tool knurls the base tube, and the fin's foot is knurled into the base tube's knurling, securing a robust bond and boosting thermal efficacy.
When the correct fin strip is used, the foot of one fin meets the next without gaps, ensuring complete coverage and protection. This design provides excellent corrosion resistance for the tube, enhancing longevity. Similar to L fins, the fin ends are securely attached to prevent unwinding, ensuring stability. For metal applications, KL-Foot tension wound finned tubes offer superior performance and are the preferred choice. Operational in environments up to 320°C (608°F) with unwavering reliability.
Advantages:
Tubes designed to resist corrosion effectively.
Engineered for outstanding vibration resistance.
Withstands extreme temperatures up to 320°C (608°F) effortlessly.
Combines exceptional thermal performance and stress resistance with unparalleled air corrosion protection.
KL finned tubes serve as an ideal replacement for any existing finned tube formats.
LL-Foot Fin / Overlapped L
Crafted from strips similar to the L type, but with a precisely controlled double L shape, rolled and curled for optimal performance. LL-Foot Fin - Overlapped L is exquisitely coiled onto a tube under tension for a seamless fit. The fin adheres to the tube perfectly, with each fin overhanging the foot of the next, ensuring complete coverage. This configuration results in outstanding protection against corrosion. In corrosive environments, this tube type is often chosen over more costly extruded fin options for its reliability and cost-effectiveness.
Our G Type Embedded Finned Tube features expertly secured fins at both ends, mirroring the established reliability of L fins. This ensures a robust and efficient performance tailored for your cooling needs. Engineered for resilience, the LL-type fin tube excels in high-temperature environments, withstanding heat up to an impressive 350 degrees Fahrenheit (177 degrees Celsius), making it a versatile and reliable choice for demanding applications.
