Extruded Fin Tube

Extruded Fin Tube, also known as Bimetallic Fin Tube, is a popular finning method for a variety of applications. The fins are created by extruding them onto an aluminium muff tube that is built to fit over the base tube with a tight tolerance.

Extrusion is performed using a Continuous Fin Extruder with Three Tooling Rolls, and high pressures in the range of 1200 psi are used. The cold working procedure ensures a perfect bond between the tube and the fin, resulting in great heat transfer efficiency. Simultaneously, the mechanical strength of the fins is greatly improved.

Fin Tubes are used in AIR FIN COOLERS, DRIERS, RADIATORS, and other applications in industries such as food and agriculture, power plants, chemical industries, steel plants, and chiller plants, among others.

Description

Extruded Fin Tubes (Bimetallic Fin Tube) have the following properties:-

Cold Extrusion is the manufacturing process.
Excellent Fin-to-Tube Bond
Excellent Heat Transfer Efficiency
Mechanical Resistance: Excellent (as a result, unlike other fin tubes, it can be cleaned often with high-pressure jets). As a result, downtime is reduced and total life is increased.)
Corrosion Protection: Because it completely covers the base tube, it provides excellent corrosion protection (except bare ends).
Temperature Range: Up to 300 degrees Celsius
