Extruded Air Preheater Finned Tube 

Extruded Fin Tube Properties: 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   Extruded Finned Tube Manufacturing Process: The fins are rotary cold rolled from a smooth thick walled hollow blank tube slid over the core tube. Three multi spindle disc packs extrude the hollow blank tube into helical high fins. During this process the inner diameter of the hollow blank tube is reduced and at the same time pressed on the core tube. This results in a mechanically solid joint. Fin Material: Aluminium/Co…
