Mechanical Properties

ASME SB163 N08825 extruded fin tubes adopt Incoloy 825 seamless base tube, which provides excellent corrosion resistance for aggressive process fluid. Extruded aluminum fins greatly increase heat exchange area for air cooling. Metallurgical bonding ensures low thermal contact resistance and good anti‑vibration performance. These tubes act as pressure‑containing barrier and heat transfer element for air coolers in petrochemical and refinery service.

Advantages 

Composite finned tubes have the following characteristics:

Highly cost effective;

The fin has good rigidity and is not easy to deform.

High heat transfer performance, small contact thermal resistance;

The contact area between the fin and the pipe is large, the fit is tight and reliable;

Good corrosion resistance, stable long-term use performance;
