Compact Thermal Performance for Demanding Applications
Maximize heat transfer efficiency while minimizing your equipment footprint with our premium Integral Low Fin Tubes. Unlike applied fins, our low fin tubes are manufactured through a meticulous cold-rolling process that extracts the fin directly from the parent base tube. This results in a truly monolithic structure, eliminating interfacial thermal resistance and providing exceptional structural integrity.
Low fin tubes (often called Trufin or integral finned tubes) are the industry standard for liquid-to-liquid and liquid-to-gas applications requiring enhanced cooling or heating in limited spaces.
Why Choose Our Low Fin Tubes?
3x Surface Enhancement: Delivers 2.5–3 times the external surface area compared to bare tubes of the same diameter.
Homogenous Material: Because the fin is part of the tube, it is impossible for the fin to detach, ensuring long-term reliability.
Compact Design: Ideal for retubing or upgrading existing shell-and-tube exchangers without replacing the shell or modifying piping.
Superior Thermal Efficiency: High fin density (19–40 FPI) optimizes heat transfer in compact spaces, reducing the total tube count and material costs.
Excellent Fouling Resistance: The cold-rolled, serrated surface promotes self-cleaning, preventing thick condensate films and reducing scaling.
Technical Specifications & Materials
We utilize advanced 3-roll oblique rolling technology to create consistent, high-precision fin profiles.
Manufacturing Process: Integral Cold-Rolled (Threaded Fins)
Tube OD Range: 12.7 mm to 31.75 mm (1/2" to 1-1/4")
Fin Pitch (FPI): 16 to 43 fins per inch
Fin Height: 0.5 mm to 1.5 mm (Typical 1/16th inch)
Length: Up to 30 meters available
Configurations: Straight, U-bent, internally grooved options available
Industry Applications
HVAC & Refrigeration: Air conditioning condensers, evaporators, and chillers.
Petrochemical/Chemical: Refining units, reactors, and process coolers.
Power Generation: Feedwater heaters and steam condensers.
Oil & Gas: Lube oil coolers and LNG/NGL plants.
Quality Control
Every batch undergoes strict inspection, including eddy current testing, hydrotests, and 50x magnification fin profile examination to ensure compliance with ASTM A498/A1012/B359 standards.
