^{Product Description:}

^{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.}

         ^{Manufacturing Process:}

          ^{A carefully degreased core tube is fitted into an aluminium primary tube.}

         ^{This assembly is then fed into the triple-spindle finning head of the fin-extruding machine.}

         ^{Three special multi-disc packs extrude the aluminium tube into helical high fins}

         ^{while reducing the inner diameter to give firm pressure contact with the core tube}

         ^{Fin materials: Aluminium}

         ^{Base tube materials: Any metallic material}

         ^Advantages:

         ^{1) Thermal}

         ^{The bonding of the outer and inner tubes removes the risk of loss of contact}

         ^{with the aluminium due to thermal stress.}

         ^{Maximum operating temperature: 250°C. The transfer coeffcient remains steady.}

         ^{Additionally as the outer sleeve is continuous no electrolytic couple is created.}

         ^{2) Mechanical}

         ^{The fins are more rigid and stand the handling shocks better,compared to types "G" an "L".}

        ^Properties:

        ^{To improve the heat transfer efficiency in the effective space.}

        ^{To Reduce the required installation space for the required heat transfer surfaces.}

        ^{To lower equipment cost while having higher operational reliability.}

        ^{The running cost is lowered due to lower tube side pressure drop.}

        ^{The rigidity of tube is increased, which improves the seismic resistance of the tube.}

        ^{Enhancement of heat transfer, reduction on flow resistance and metal consumption.}

       ^{Applications:}

       ^{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.}
