This product is an integral low finned tube manufactured from high-quality stainless steel. The fins are formed directly from the parent tube material through a cold-forming process, ensuring metallurgical continuity between the tube and fins. This construction provides excellent corrosion resistance, high structural integrity, and long-term reliability in demanding industrial heat transfer environments.
Tube Type: Integral low finned tube
Base Material: Stainless steel (common grades include 304, 304L, 316, 316L, 321)
Outside Diameter (OD): Typically 12.7 mm – 38.1 mm
Wall Thickness: 0.9 mm – 3.0 mm (customizable)
Fin Height: 0.8 mm – 1.5 mm
Fin Density: 16 – 26 fins per inch (FPI)
Tube Length: Up to 18 meters
Manufacturing Process: Cold rolling / integral fin forming
Surface Condition: Pickled, bright annealed, or polished
Integral fin structure eliminates fin-to-tube contact resistance
Significantly increased external surface area for enhanced heat transfer
Excellent resistance to corrosion and oxidation
High mechanical strength suitable for high-pressure applications
Long service life with minimal maintenance
Based on common customer concerns in industrial heat exchanger applications, our stainless steel low fin tubes address the following key issues effectively:
Heat Transfer Efficiency:
Customers often worry about insufficient heat exchange performance. The integral low fin design increases surface area by 2–4 times compared to plain tubes, greatly improving thermal efficiency.
Fin Bonding Reliability:
Unlike wrapped or soldered fins, integral fins are formed from the base tube itself, eliminating the risk of fin loosening or detachment during long-term operation.
Corrosion Resistance:
Stainless steel materials provide excellent resistance against moisture, chemicals, and aggressive process media, reducing replacement frequency and downtime.
Operational Cost Reduction:
Higher heat transfer efficiency allows for more compact heat exchanger designs, lowering material usage, energy consumption, and overall system costs.
Stable Performance in Harsh Conditions:
The tubes maintain mechanical integrity under high temperature, pressure, and vibration, ensuring consistent performance in industrial environments.
