Discover our diverse range of finned tubes, including tension wound finned tubes, embedded finned tubes, and extruded finned tubes, each crafted to meet your specific cooling needs.
Our tension wound finned tubes are meticulously crafted by winding a robust strip of either aluminium or copper around the tube, maintaining precise tension for optimal performance. This advanced strip winding technology allows us to offer a variety of fin types: L-Fin, LL-Fin, and KL-Fin, each engineered for specific applications.
Introducing Embedded Fins (G-Fins) which are expertly created by winding an aluminium or copper strip into a meticulously machined helical groove on the tube's exterior surface.
Our tension wound finned tubes, embedded finned tubes, and extruded finned tubes serve as cornerstone devices for air coolers, with applications spanning:
State-of-the-art heat exchangers, seamlessly integrated into power plants, including electric, nuclear, thermal, and geothermal facilities.
Efficient and reliable steam condensate systems.
Critical components in the chemical and petrochemical industries.
Essential technology in food processing plants and cutting-edge refrigeration systems.
Vital solutions for industrial applications such as steel mills, incinerators, and gas compression facilities.
L-Foot Finned Tube
Our L-Foot Finned Tubes offer an exceptional balance of efficiency and cost-effectiveness, ensuring maximum heat transfer even at lower temperatures. The innovative L-shaped fin design securely holds each fin in place, expertly resisting heat cycling and high-velocity air vibrations.
We provide several variations of L-Foot Finned Tubes to precisely match your requirements:
Knurled Fin Features an interference fit fin, with expertly executed mechanical knurling to firmly bond the fin material to the tube wall.
LL Fin Our Double Overlap fin, also known as Double LL, offers dual strip thickness coverage, ensuring complete base tube protection.
Perforated L Fin This fin design enhances air flow with 'tear drop' slits around the helix, optimizing efficiency.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Also referred to as Wrap-On Finned Tubes, these are ideal for applications where temperatures remain below 300°F, offering necessary tube wall protection at lower temperatures. L-Foot tension wound finned tubes are engineered with a thin aluminium fin strip, tightly wound in a helical pattern around the tube for superior performance. A 'foot' is initially formed on one side of the fin strip, lending the name L-Foot to this innovative design. Following this, the strip is meticulously wound around the tube, with the foot making firm contact with the tube's outer surface. The short horizontal limb of each L fin is in complete contact with the base tube's surface, ensuring comprehensive coverage. Tension in the fin strip during wrapping ensures the fin foot is forcefully seated against the tube, maintaining a secure hold. L-footed finned tubes deliver unparalleled heat transfer capabilities at reduced temperatures. The distinctive L-shaped design maintains fin rigidity, effectively withstanding both heat cycling and high-velocity air vibrations. This innovative fin design also provides a degree of atmospheric protection for the tube wall, safeguarding against corrosion. The extensive contact surface between the tube and fin significantly enhances heat transfer efficiency. Engineered for efficiency, this fin design remains cost-effective, providing excellent value.
To ensure durability, the ends of the fins are securely stapled, preventing any unraveling and maintaining consistent contact between the fin foot and the tube. This contact plays a pivotal role in the seamless operation of the air cooler, ensuring optimal heat transfer from the tube wall, through the fin, and into the surrounding ambient air, maximizing cooling efficiency.
Advantages:
Perfectly tailored for low-temperature applications, offering unmatched performance.
This finning type stands out as the most cost-effective method compared to other alternatives, delivering exceptional value.
Even if fins fail during production, they can be effortlessly removed, allowing the bare tube to be reused for finning, enhancing sustainability.
Ingeniously designed, there's no need to carve a helical groove over the core tube, simplifying production.
Fins can be strategically placed on a very thin-walled tube, which is particularly advantageous when utilizing expensive alloys as the core tube, optimizing material use.
The tube is engineered to withstand temperatures up to 130°C, offering superior resistance to atmospheric corrosion and thermal stress.
Application:
Ideal for oil and gas refineries, enhancing operational efficiency.
Perfect for use in petroleum, chemical, and petrochemical industries, ensuring robust performance.
Tailored for natural gas treatment, optimizing energy management.
An excellent choice for the steel making industry, bolstering production efficacy.
Empowering power plants with superior thermal management solutions.
Perfect for air conditioning systems, enhancing cooling capabilities.
Ideal for compressor coolers, boosting performance.
KL Footed Fin / Knurled L Footed Fin
The KL fin, also renowned as the knurled L fin, offers innovative design and functionality. This finned tube mirrors the Wrap-On fin design, constructed using both Wrap-On and Embedded techniques for enhanced efficiency. Crafted from strips prepared into an L shape, similar to the L type, the fins are then rolled into a taper and curled for optimal performance. The fins are meticulously helically wound onto the tube in a continuous loop, maintained under precise tension. The tube is embraced by the fin, ensuring a snug fit and enhanced performance. A specialized spinning tool knurls the base tube, integrating the foot of the fin into the knurling of the base tube, resulting in a tight bond and optimized thermal performance.
Utilizing the correct fin strip ensures the foot of one fin aligns perfectly with the next, eliminating space between fins. This precise alignment offers superior protection against corrosion for the tube. Similar to L fins, the fins are securely attached at each end to prevent unwinding, ensuring long-lasting durability. In metal-involved applications, KL-Foot tension wound finned tubes are the go-to choice for their reliability. Capable of withstanding a maximum operating temperature of up to 320°C (608°F), ensuring robust performance under extreme conditions.
Advantages:
Corrosion-resistant Tubes, promising longevity and reliability.
Built with vibration resistance, ensuring stability and performance.
Expertly designed to endure temperatures up to 320°C (608°F), enhancing operational safety and efficiency.
A unique combination of high thermal performance, stress resistance, and protection from air corrosion, offering unparalleled benefits.
KL finned tubes can replace any form of finned tubes, providing versatile and adaptable solutions.
LL-Foot Fin / Overlapped L
Crafted from strips in a process akin to the L type, with the foot carefully prepared into a stepped double L shape, rolled into a taper for precision. The LL-Foot Fin, featuring an Overlapped L design, is then helically coiled onto a tube under controlled tension, ensuring a secure fit. The fin embraces the tube, with each fin overhanging the foot of the next, fully covering the base tube for complete protection. This design significantly enhances the tube's protection against corrosion, ensuring longevity. In corrosive environments, this tube serves as a cost-effective alternative to the pricier extruded type fin, offering reliable protection and performance.
The fins are meticulously secured at each end, mirroring the reliable and effective technique used for L fins, ensuring steadfastness and efficiency throughout the product's lifespan. The robust and versatile LL-type fin tube is engineered to perform seamlessly in environments with temperatures soaring up to a significant 350 degrees Fahrenheit (177 degrees Celsius).
