EXTRUDED FIN TUBE (BIMETALLIC FIN TUBE)
EXTRUDED FINNED TUBE----This fin type is formed from a bi-metallic tube consisting of an aluminium outer tube and an inner tube of almost any material.
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 Aluminum 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, and Chiller Plants etc.
Manufacturing Process: Cold Extrusion
Fin To Tube Bond: Excellent
Heat Transfer Efficiency: Excellent
Mechanical Resistance: Excellent (Hence can be frequently cleaned with high pressure jets unlike other fin tubes. Thereby reducing down time and increasing overall life)
Corrosion Protection: Gives excellent corrosion protection to the base tube since it entirely covers the base tube (except bare ends).
Temperature Range: Upto Maximum 300 Deg C
Application
Aftercoolers, air coolers, air heaters, charge air chillers, condensers, convection heaters, electric heaters, evaporators, fluid coolers, gas coolers, heat pipes, hydrogen coolers, industrial tumble dryers, intercoolers, immersion heaters, oil coolers, radiators, refrigeration, solvent recovery and steam to air heat exchangers.
