Our company takes immense pride in having a highly skilled and dedicated professional sales and technical team.
We are committed to designing exceptional solutions and offering tailored product customization to perfectly meet your unique needs.
Currently, we boast advanced production facilities capable of manufacturing a diverse range of finned tubes, as elaborated below:
EXTRUDED FIN TUBE (Bimetallic Fin Tube & Integral Low Fin Tube) - renowned for its durability and efficient performance.
'G' TYPE FIN TUBE (EMBEDDED FIN TUBE) - engineered for superior heat transfer efficiency and longevity.
'L' 'LL' 'KL' TYPE FIN TUBE (WRAP AROUND FIN TUBE) - offering versatility and exceptional heat exchange performance.
LASER WELDED FINNED TUBE - providing precision and unmatched durability through cutting-edge laser welding technology.
HIGH FREQUENCY WELDED FIN TUBE (Including Serrated Finned Tube) - designed for robust construction and optimal thermal efficiency.
L-Foot Finned Tube
Combining exceptional efficiency with affordability, the L-footed finned tubing is designed to facilitate optimal heat transfer even at reduced temperatures. The ingenious L-shaped design secures the fins robustly, ensuring resilience against both heat cycling and high-velocity air vibration.
Explore the L-Foot Finned Tube in these compelling Fin variations:
Knurled Fin - Engineered with an interference fit, this fin is meticulously knurled to enhance the mechanical bond between the fin material and the tube surface.
LL Fin - Featuring a Double Overlap fin configuration, the double LL provides complete base tube coverage with dual strip thickness.
Perforated L Fin - The innovative 'tear drop' slits along the helix create a dynamic airflow disruption, enhancing efficiency.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Also known as Wrap-On Finned Tubes, these are ideal for applications below 300°F, offering necessary protection for the tube wall in low-temperature settings. L-Foot tension wound finned tubes feature a thin aluminium fin strip expertly wound around the tube's circumference. An initial 'foot' is crafted on one side of the fin strip, lending the name L-Foot. Subsequently, the strip is tightly wound around the tube, with the foot ensuring consistent contact with the outer surface. Each L's short horizontal limb ensures full coverage of the base-tube surface, optimizing performance. The tension applied during wrapping ensures the fin foot is securely seated, maintaining the fin's stability. Maximize heat transfer efficiently at lower temperatures with L-footed finned tubing. The distinctive L-shaped design secures fins to endure heat cycling and the rigors of high-velocity air flow. This design also provides a level of atmospheric protection, guarding the tube wall against corrosion. A broad contact interface between the tube and fin enhances heat transfer capabilities. Efficient and cost-effective, this fin design is a hallmark of excellence.
Fin ends are stapled to prevent unravelling, maintaining crucial contact between the fin foot and the tube. This contact is vital for air cooler function, facilitating heat transfer from tube wall, through the fin, to ambient air.
Advantages:
Perfect for low-temperature applications.
The most economical finning method available.
Easy removal of failed fins allows the bare tube to be reused for new finning.
No helical groove needed on the core tube.
Ideal for thin-walled tubes, especially when using pricey alloy cores.
Capable of withstanding up to 130°C without risking corrosion or thermal stress.
Application:
Oil and gas refineries
Petroleum, chemical, and petrochemical industries
Natural gas processing
Steel production industry
Power generation facilities
Air conditioning systems
Compressor coolers
Presenting the KL Footed Fin, also known as the Knurled L Footed Fin, a marvel of engineering and design.
The remarkable KL fin is widely acclaimed as the knurled L fin, offering unparalleled efficiency. This finned tube ingeniously mimics the Wrap-On fin and is meticulously crafted using the Wrap-On and Embedded techniques. The fins are expertly fashioned from strips designed into an elegant L shape akin to the L type, and then skillfully rolled into a taper that encourages a graceful curl. Subsequently, it is helically wound onto the tube in a seamless continuous loop, held under precise tension. The fin lovingly embraces the tube. A sophisticated spinning tool knurls the base tube, allowing the foot of the fin to integrate perfectly with the knurling of the base tube, creating an extraordinary bond and optimizing thermal performance.
With the right fin strip, each fin's foot perfectly aligns with the next, eliminating any gaps between them. This innovative design significantly enhances the tube's resistance to corrosion. Much like L fins, these fins are securely attached at each end to ensure they remain perfectly in place. KL-Foot tension wound finned tubes are the go-to solution for metal applications, providing superior efficiency and durability. Able to withstand a maximum operating temperature of up to 320°C (608°F), ensuring reliability and performance.
Advantages:
Corrosion-resistant Tubes - Unyielding in harsh environments.
Vibration resistance - Unmatched stability and longevity.
Temperature endurance - Capable of withstanding up to 320°C (608°F).
One-of-a-kind combination of high thermal performance, stress resistance, and unparalleled protection from air corrosion.
KL fins are the versatile choice, effortlessly replacing any form of finned tube.
The LL-Foot Fin / Overlapped L - A testament to advanced engineering.
These fins are crafted from strips similarly to the L type, but with a meticulously controlled stepped double L shape, skillfully rolled into a taper for a graceful curl. The LL-Foot Fin - Overlapped L is then expertly helically coiled onto a tube under precise tension. The fin elegantly clings to the tube, with each fin seamlessly overhanging the foot of the subsequent fin, fully shielding the base tube. This design ensures the tube is exceptionally well-protected from corrosion, enhancing longevity. In corrosion-prone environments, this tube stands as a cost-effective alternative to more expensive extruded type fins.
Like L fins, these are securely fastened at each end, ensuring structural integrity. The LL-type fin tube is engineered to perform optimally at temperatures up to 350°F (177°C).
