Heat Exchanger Finned Tube

  1. Finned tube refers to a kind of heat exchange device. To improve the heat exchange efficiency, fins are usually added on the surface of core tube
  2. to increase the outer surface area (or inner surface area).
  3. The finned tube is a new, wear-resistant and efficient heat exchange material. It is a high-efficiency and energy-saving heat exchange element, which has the characteristics of high heat exchange efficiency, large heat dissipation area, long service life, wide temperature range and high pressure adaption.
  4. Chal provides a full range of finned tubes for heat exchanger with reliable quality, high performance, complete designs and competitive price.

Heat Exchanger Finned Tube


  Advantages of finned tube  

1. Finned tube has compact structure, easy and economical to install. It reduces the joints compared to bare tube, making installation more quickly and cost-saving, reduce the possibility of water-leaking at the connection.  
Simple for maintenance, you basically don’t need to maintain finned tubes after installation.

2. High efficiency, the finned tube is full-contact of the fin and aluminum pipe, the heat dissipation area is more than 7-8 times that of the bare tube, the inside is smoother, and the internal water flow resistance is small.

3. Long service life, high mechanical strength of the combination of fins and pipes. The tensile strength is above 200Mpa.

4. Stable heat transfer performance. It has little temperature fluctuations, reduces the high temperature corrosion and over-temperature damage of the metal surface.

5. Widely adaptable for heat exchange between air-air, air-liquid, liquid-liquid and various fluids.


  Categories of finned tube in different process technology and shapes  

1. High frequency welded finned tube (high frequency welded open-tooth finned tube)

2. Square-finned tube (H-type finned tube)

3. Needle tube (nailhead tube)

4. Laser welded finned tubes

5. Inlaid finned tube

   1)G-type finned tube(Embedded finned tube)

   2)KL embossed wound finned tube

   3)L wound finned tube

6. DR extruded high finned tube (solid and serrated fins)

7. Low-finned tube

8. Threaded tube

9. Wave joint tube
