We specialize in designing tailored solutions and customizing products to perfectly meet your unique specifications.
We proudly operate state-of-the-art production facilities capable of manufacturing a wide array of high-quality finned tubes, as detailed below.
EXTRUDED FIN TUBE (Bimetallic Fin Tube & Integral Low Fin Tube): Engineered for superior performance, these tubes offer exceptional durability and efficiency.
'G' TYPE FIN TUBE (EMBEDDED FIN TUBE): Designed for optimized heat transfer, ensuring reliability and effectiveness in various applications.
'L' 'LL' 'KL' TYPE FIN TUBE (WRAP AROUND FIN TUBE): These versatile tubes are crafted for enhanced heat exchange capabilities.
LASER WELDED FINNED TUBE: Precision-welded for strength and longevity, offering unparalleled heat transfer solutions.
HIGH FREQUENCY WELDED FIN TUBE (Including Serrated Finned Tube): Known for its robust construction and high-efficiency thermal performance.
L-Foot Finned Tube
Renowned for its unparalleled efficiency and cost-effectiveness, the L-footed finned tubing ensures optimal heat transfer even at reduced temperatures. Ingeniously crafted, the unique L-shaped design ensures fins remain steadfast, enduring heat cycling and high-velocity air vibrations with remarkable resilience.
The L-Foot Finned Tube is available in the following innovative fin variations:
Knurled Fin - An advanced interference fit fin featuring mechanical knurling for enhanced adhesion of the fin material to the tube wall surface.
LL Fin - Characterized by Double Overlap fin (the double LL), this design offers comprehensive dual strip thickness coverage for the entire base tube.
Perforated L Fin - Enhanced with 'tear drop' slits around the helix, this innovation disrupts airflow for improved performance.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes Also identified as Wrap-On Finned Tubes, these are meticulously designed for conditions where temperatures do not exceed approximately 300 degrees Fahrenheit, making them ideal for low-temperature applications requiring a degree of tube wall protection. Crafted with precision, L-Foot tension wound finned tubes feature a thin aluminum fin strip artfully wound helically around the tube circumference. Ingeniously, a 'foot' is formed on one side of the fin strip to create the distinguished L-Foot design. Tightly wound around the tube, the foot maintains firm contact with the tube's outer surface, ensuring a secure fit. The short horizontal limb of each L intimately contacts the base-tube surface, ensuring complete coverage. The tension in the fin strip during wrapping ensures the fin foot is firmly seated and securely held in place. L-footed finned tubing guarantees peak heat transfer efficiency at lower temperatures. The distinct L-shaped design maintains fin rigidity, resisting heat cycling and high-velocity air vibration with ease. This design offers significant atmospheric shielding for the tube wall against corrosion. The expansive contact surface between the tube and finning significantly boosts heat transfer efficiency. This fin design is exceptionally efficient, combining unparalleled performance with cost-effectiveness.
Fin ends are expertly stapled to prevent the unraveling of aluminum fins, thus maintaining the vital contact between the fin foot and the tube. This crucial contact is vital for air cooler operation, ensuring seamless heat transfer from the tube wall to the ambient air.
Advantages:
Tailored for low-temperature applications, offering optimal solutions.
This finning method is the pinnacle of cost-effectiveness, outshining alternatives.
Easily replace failed fins during production; the bare tube can be re-finned efficiently.
Eliminates the need for creating a helical groove over the core tube.
Allows fin placement on very thin-walled tubes, ideal for when using pricey alloys as the core tube.
Capable of withstanding temperatures up to 130°C without succumbing to atmospheric corrosion or thermal stress.
Application:
Oil and gas refineries
Petroleum, chemical, and petrochemical industries
Natural gas treatment
Steel manufacturing industry
Power plants
Air Conditioning
Compressor Coolers
KL Footed Fin / Knurled L Footed Fin
The KL Fin is also known as the Knurled L Fin. This remarkable finned tube closely mirrors the Wrap-On fin, crafted through both Wrap-On and Embedded techniques for superior performance. Fins are expertly fashioned from strips, meticulously designed into an L shape comparable to the L type, then rolled into a taper inducing a natural curl. Subsequently, it is helically wound onto the tube in a seamless continuous loop under precise tension. The fin lovingly envelops the tube, ensuring optimal contact. A rotating tool intricately knurls the base tube, enabling the fin foot to integrate seamlessly, resulting in a robust bond and enhanced thermal efficiency.
Correct fin strip utilization ensures each fin foot meets the next without gaps, maintaining continuity. This offers formidable protection against corrosion, preserving the tube's integrity. Much like L fins, these fins are affixed at both ends to avert unwinding. Typically, in metal applications, KL-Foot tension wound finned tubes are the go-to choice. They operate efficiently up to an impressive 320°C (608°F) temperature threshold.
Advantages:
Corrosion-Resistant Tubes
Outstanding Vibration Resistance
Capable of withstanding heat up to 320°C (608°F) with ease.
High thermal performance coupled with stress resistance and anti-corrosion properties creates an unmatched combination.
KL fins can seamlessly replace any type of finned tube.
LL-Foot Fin / Overlapped L
LL fins are ingeniously crafted from strips, akin to the L type but with a double L shape foot, meticulously rolled to allow curling. The LL-Foot Fin is then helically coiled onto the tube under precise tension. The fin secures the tube, with one fin elegantly overlapping the foot of the next, ensuring comprehensive coverage. This design ensures the tube is thoroughly shielded from corrosion. In corrosive environments, this tube form often serves as a cost-effective alternative to pricey extruded fins.
Fins are securely anchored at each end, akin to L fins. The LL-type fin tube is ideal for temperatures reaching up to 350°F (177°C).
