Product Description

Product Parameters

We proudly offer a diverse array of finned tubes, including tension wound finned tubes, embedded finned tubes, and extruded finned tubes. Each type is meticulously engineered to meet distinct industrial needs.

Tension wound finned tubes are skillfully crafted by tension-winding a strip of aluminium or copper around the tube, ensuring a secure and high-performance installation. Our innovative strip winding technology enables the creation of various fin types: L-Fin, LL-Fin, KL-Fin, each designed for specific applications.

Embedded fins, also known as G-Fins, are expertly produced by winding aluminium or copper strips into a precisely machined helical groove on the tube's outer surface, enhancing efficiency and durability.

Tension wound, embedded, and extruded finned tubes are essential components for air coolers, catering to diverse application fields such as:

Heat exchangers in power plants, including electric, nuclear, thermal, and geothermal facilities, demanding outstanding heat transfer solutions.

Steam condensate systems, where efficient temperature regulation is crucial.

Chemical and petrochemical industry, providing robust and reliable thermal management.

Food processing plants and cutting-edge refrigeration technology, ensuring optimal performance and safety.

Various industrial settings, including steel mills, incinerators, and gas compression facilities, where superior heat resistance is required.

L-Foot Finned Tube

This highly efficient and cost-effective solution, the L-footed finned tubing, delivers exceptional heat transfer even at lower temperatures. Its unique L-shaped design rigidly secures fins, expertly withstanding heat cycling and high-velocity air vibrations.

The L-Foot Finned Tube can be customized with the following fin variations:

Knurled Fin - This variation offers an interference fit type fin with skillful mechanical knurling of the fin material to the tube's surface for enhanced durability.

LL Fin - Featuring double overlap, the double LL coverage provides robust double strip thickness coverage of the base tube.

Perforated L Fin - This enhanced design incorporates 'tear drop' slits along the helix to disrupt airflow, boosting efficiency.

L-Foot Fin / Wrap-On Fin

L-Foot Tension Wound Finned Tubes These, also known as Wrap-On Finned Tubes, are perfect for applications below 300°F, offering crucial tube wall protection at lower temperatures. Crafted with precision, L-Foot tension wound finned tubes feature a thin aluminium fin strip tightly helically wound around the tube. The 'foot' is ingeniously formed on one side of the fin strip, giving L-Foot its distinctive name. This strip is then expertly wound, with the foot bearing firmly on the tube's outer surface. The short horizontal limb of each L maintains full contact with the base-tube surface, ensuring complete coverage. The tension in the fin strip, as it wraps around the tube, ensures the fin foot is firmly seated, maintaining its position with precision. L-footed finned tubing maximizes heat transfer capabilities at lower temperatures. Its ingenious L-shaped design secures fins rigidly, combating heat cycling and high-velocity air vibrations effortlessly. Notably, this fin type also provides a degree of atmospheric protection for the tube wall against corrosion, prolonging its service life. The broad contact surface between the tube and fin enhances heat transfer efficiency significantly. This highly efficient and cost-effective fin design promises optimal performance at a competitive price.

The fin ends are stapled firmly, preventing the aluminium fin from unraveling and ensuring consistent contact between the fin foot and the tube. This vital component is pivotal for the air cooler's function. It efficiently transfers heat from the tube wall, through the fin, and into the ambient air, ensuring optimal performance.

Advantages:

Perfectly crafted for low-temperature applications, offering unmatched reliability.

This finning type emerges as the most cost-efficient method available, delivering unmatched value.

Effortlessly detachable failed fins ensure seamless production continuity, allowing the bare tube to be effectively reused for finning purposes.

No helical groove needed on the core tube, simplifying the process.

Fins can be positioned on ultra-thin-walled tubes, especially desirable with costly alloy core tubes, maximizing material efficiency.

The tube boasts a remarkable tolerance to temperatures up to 130°C, mitigating atmospheric corrosion or thermal stress risks.

Application:

Oil and gas refineries

Petroleum, chemical, and petrochemical industries

Natural gas treatment

Steelmaking industry

Power plants

Air conditioning

Compressor coolers

KL Footed Fin / Knurled L Footed Fin

The innovative KL fin is recognized as the knurled L fin, a marvel of engineering. Crafted using both Wrap-On and Embedded techniques, this finned tube is nearly identical to the Wrap-On fin, blending precision with performance. Fins are expertly crafted from L-shaped strips, then rolled into a taper, curling perfectly to fit. Meticulously helically wound in a continuous loop under tension, ensuring a flawless fit. The tube is snugly embraced by the fin, enhancing contact. A spinning tool expertly knurls the base tube, securing the fin's footing into the knurling, forming an impeccable bond that boosts thermal performance.

With the right fin strip, fins perfectly align with no gaps, optimizing protection. This innovation ensures the tube is shielded from corrosion, enhancing durability. Similar to L fins, each end of the fins is securely attached, preventing unwinding and ensuring stability. KL-Foot tension-wound finned tubes are the go-to solution for metal-involved applications, providing reliability and efficiency. Withstands up to 320°C (608°F) for maximum operational efficiency and reliability.

Advantages:

Tubes resistant to corrosion, ensuring longevity and performance.

Exceptional vibration resistance, safeguarding structural integrity.

Capable of enduring temperatures up to 320°C (608°F), a testament to its robust design.

An unparalleled combination of high thermal performance and stress resistance, coupled with superior air corrosion protection.

KL offers a versatile replacement for any finned tube type, providing flexibility and adaptability.

LL-Foot Fin / Overlapped L

Fins are crafted from strips, akin to the L type, but the foot is meticulously shaped into a double L, ensuring perfect curl upon rolling. The LL-Foot Fin - Overlapped L is expertly helically coiled onto a tube under tension, achieving a perfect fit. Fins grasp the tube, with each fin's foot beautifully overlapping the next, fully covering the base tube. This exceptional design provides the tube with excellent corrosion protection, enhancing its lifespan. In corrosive environments, this cost-effective alternative to the pricier extruded type fin excels, offering superb protection and performance.

The fins are meticulously secured at each end, employing the same reliable method as used with L-shaped fins, ensuring optimal performance and longevity. The LL-type fin tube is engineered to withstand high temperatures of up to 350 degrees Fahrenheit (177°C), making it ideal for demanding thermal applications.
