Finned tubes are specialized heat exchange components with external fins attached to the base tube to significantly enlarge the heat transfer surface. They improve thermal efficiency in various industrial heat exchangers.

1. Structure

• Base Tube: Carries the working fluid; made from carbon steel, stainless steel, alloy steel, copper, or aluminum.
• Fins: Extend the heat transfer surface; come in different shapes and sizes.
• Joint Part: Ensures secure connection between fins and tube for stable thermal conduction.

2. Manufacturing Process

• Extruded Finned Tubes: Fins formed integrally with tube; high bonding strength, excellent thermal conductivity, anti-loosening.
• L/LL/KL Footed Finned Tubes: Wrapped fins with foot design; cost-effective and easy to produce for general conditions.
• High-Frequency Welded Finned Tubes: Fins welded via high-frequency welding; strong, suitable for high temperature and pressure.
• Embedded Finned Tubes: Fins embedded into tube surface; excellent for severe vibration conditions.

Fin Shapes: Circular Fin, Square Fin, Spiral Fin, Serrated Fin, Plate Fin

3. Applications

• Power Plants: Boiler economizers, air preheaters, flue gas heat recovery systems.
• Petrochemical Industry: Process heat exchangers, waste heat recovery, heating furnaces.
• HVAC & Refrigeration: Air coolers, radiators, evaporators, condensers.
• Metallurgy & Light Industry: Industrial ovens, drying equipment, waste heat utilization devices.
