Extruded Fin Tube

EXTRUDED FIN TUBE (BIMETALLIC FIN TUBE ) :-

The Extruded Fin Tube also known as Bimetallic Fin Tube is one of the most preferred finning processes for various applications.

The fins are manufactured by Extruding the Fins on the Aluminium Muff Tube which is made to Fit with close tolerance over the Base Tube .

The Extrusion takes place on a Continuous Fin Extruder with Three Tooling rolls and extrusion takes place at high pressures in the range of 1200 psi . Because of the cold working process the Bond between the Tube and fin is flawless and hence gives excellent Heat Transfer Efficiency. At the same time the mechanical strength of the fins is also enhanced drastically.

These Fin Tubes find application in AIR FIN COOLERS, DRIERS, RADIATORS etc and are preferred in Industries like Food and Agriculture , Power Plants , Chemical Industries , Steel Plants , Chiller Plants etc,

Properties of Extruded Fin Tubes (Bimetallic Fin Tube ) :-

1. Manufacturing Process :- Cold Extrusion

2. Fin To Tube Bond :- Excellent

3. Heat Transfer Efficiency :- Excellent

4. Mechanical Resistance: – Excellent (Hence can be frequently cleaned with high pressure jets unlike other fin tubes. Thereby reducing down time and increasing overall life)

5. Corrosion Protection: – Gives excellent corrosion protection to the base tube since it entirely covers the base tube (except bare ends).

6. Temperature Range :- Upto Maximum 300 Deg C
