What are the different types of fin tubes?

Finned tubes are important components widely used in heat exchange equipment, designed to improve heat transfer efficiency by increasing the contact area with the fluid. Depending on the application, material selection, and manufacturing process, finned tubes can be classified into several types.

1. Classification by Manufacturing Process

1) Extruded finned tubes;

2) Welded finned tubes (high-frequency welded finned tubes, submerged arc welded finned tubes);

3) Roll-formed finned tubes;

4) Kitted finned tubes;

5) Cast finned tubes;

6) Tension-wound finned tubes;

7) Laminated tubes.

Classification by fin shape:

1) Square finned tube;

2) Circular finned tube;

3) Spiral finned tube;

4) Longitudinal finned tube;

5) Corrugated finned tube;

6) Helical serrated finned tubes;

7) Needle-shaped finned tube;

8) Integral plate-shaped finned tube (plate fin);

9) Inner finned tube. And so on.
