Experience elevated efficiency with our diverse range of finned tubes, encompassing tension wound finned tubes, embedded finned tubes, and extruded finned tubes, each meticulously crafted to maximize performance.
Our tension wound finned tubes are expertly formed by the precise winding of aluminium or copper strips around the tube under high tension, ensuring robust and reliable performance. Innovative strip winding technology enables the creation of various fin types, including the versatile L-Fin, the enhanced LL-Fin, and the durable KL-Fin, catering to specific thermal needs.
Embedded fins (G-Fins) are precision-engineered by winding aluminium or copper strips into a helical groove skillfully machined on the tube's outer surface, delivering superior thermal conduction.
Our tension wound, embedded, and extruded finned tubes play a pivotal role in air coolers, with common application fields including:
Heat exchangers for power plants, extending across electric, nuclear, thermal, and geothermal sectors.
Steam condensate systems, providing exceptional thermal management.
Chemical and petrochemical industry applications, where efficiency and reliability are paramount.
Food processing plants and advanced refrigeration technology, ensuring optimal performance.
Industrial applications, including steel mills, incinerators, and gas compression facilities, benefit from our advanced tubing solutions.
L-Foot Finned Tube
Delivering unparalleled efficiency, the cost-effective L-footed finned tubing ensures maximum heat transfer even at lower temperatures. Its distinctive L-shaped design maintains fin rigidity to endure heat cycling and handle high-velocity air vibrations confidently.
The L-Foot Finned Tube comes with the following exciting Fin variations:
Knurled Fin - Featuring an interference fit type, with mechanically knurled fin material securely bonded to the tube wall surface, enhancing its thermal exchange capabilities.
LL Fin - Double Overlap fin (the robust double LL), offers a doubled strip thickness, fully covering the base tube for enhanced longevity and efficiency.
Perforated L Fin - This advanced fin design creates 'tear drop' slits along the helix, ingeniously disrupting airflow for improved heat dissipation.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes commonly referred to as Wrap-On Finned Tubes, are ideal for low-temperature applications, where temperatures remain below about 300 degrees Fahrenheit, offering necessary tube wall protection. These tubes consist of a thin aluminium fin strip expertly wound in a helical pattern around the tube circumference, ensuring tight bonding and effective heat transfer. Each fin strip initially forms a 'foot' on one side (thus named L-Foot), providing a secure base for the winding process. The strip is meticulously wound around the tube, with the foot ensuring a steadfast grip on the tube's outer surface. The short horizontal limb of each L remains in complete contact with the base-tube surface, ensuring comprehensive coverage. The tension applied during the wrapping process ensures the fin foot is firmly seated, maintaining optimal positioning and performance. L-footed finned tubing is engineered for maximum heat transfer at lower temperatures, catering to diverse industrial needs. Its unique L-shaped design provides robust rigidity, enduring heat cycling and handling high-velocity air vibrations with ease. This fin design offers substantial atmospheric protection, safeguarding the tube wall against potential corrosion threats. The expansive contact surface between the tube and fin enhances heat transfer, setting a benchmark for efficiency. Ingeniously designed for high efficiency, this fin remains cost-effective, delivering exceptional value.
The fin ends are expertly stapled to prevent unravelling, ensuring a secure contact between the fin foot and the tube for sustained performance. This vital contact point is crucial for the air cooler's operation, expertly transferring heat from the robust tube wall, seamlessly through the fin, and dispersing it into the surrounding ambient air with remarkable efficiency.
Advantages:
Expertly crafted for optimal performance in low-temperature environments.
Among finning options, this type stands out as the most cost-effective solution, offering unparalleled value.
Failed fins can be effortlessly removed during production, allowing the bare tube to be seamlessly reused for finning—both efficient and sustainable.
Eliminates the need to carve a helical groove into the core tube, simplifying the production process.
Ideal for use with thin-walled tubes, this method is particularly advantageous when working with costly alloy core tubes, maximizing material efficiency.
Engineered to endure temperatures up to 130°C, this tube resists atmospheric corrosion and thermal stress with ease.
Application:
Essential in oil and gas refineries
Widely utilized across petroleum, chemical, and petrochemical industries
Integral to natural gas treatment processes
A vital component in the steel making industry
Indispensable for power plants
Key role in efficient air conditioning systems
Optimizes performance in compressor coolers
KL Footed Fin / Knurled L Footed Fin
The KL fin is alternatively referred to as the knurled L fin. This versatile finned tube, akin to the Wrap-On variant, is skillfully manufactured using a combination of Wrap-On and Embedded techniques. Crafted from pre-shaped strips into an L configuration, these fins are meticulously rolled into a taper, creating a graceful curl. Expertly wound helically onto the tube in a continuous loop under tension, ensuring a secure and robust fit. The fin embraces the tube, ensuring maximum contact and heat transfer. A precision spinning tool knurls the base tube, integrating the fin's foot into the knurling, resulting in an exceptionally tight bond for enhanced thermal performance.
Utilizing the correct fin strip, each fin abuts the next without gaps, providing continuous protection and efficiency. This design serves to shield the tube from potential corrosion, enhancing its longevity. Mirroring the attachment style of L fins, these fins are secured at both ends to prevent unwinding, ensuring long-term stability. KL-Foot tension wound finned tubes are frequently chosen for metal applications, offering superior performance. Proficiently engineered to handle a maximum operating temperature of up to 320°C (608°F), offering robust reliability.
Advantages:
Corrosion-resistant Tubes
Exemplary vibration resistance
Engineered to endure temperatures reaching 320°C (608°F) with outstanding reliability.
An unmatched combination of high thermal performance, stress resistance, and protection against air corrosion.
KL fins offer versatile replacement options for any type of finned tube.
LL-Foot Fin / Overlapped L
Crafted similarly to the L type, these fins feature a meticulously controlled stepped double L shape, rolled into a taper for optimal performance. The LL-Foot Fin - Overlapped L is expertly wound helically onto a tube under tension, ensuring a tight and secure fit. The fin clings protectively to the tube, with each fin overlapping the foot of the next, completely enveloping the base tube for comprehensive protection. This design choice ensures the tube is thoroughly protected from corrosion, extending its lifespan. In corrosive environments, this tube design is often selected as a cost-effective alternative to the more expensive extruded fin type.
The ingenious design of our product ensures that the fins are securely fastened at each end, utilizing the same reliable method as L fins. This guarantees enhanced performance and steadfast durability. Our advanced LL-type fin tube stands out for its remarkable resilience, effortlessly withstanding temperatures up to a scorching 350 degrees Fahrenheit (177C degree). This makes it ideal for high-temperature applications.
