Product Description

Finned Tube Aluminum Extruded Fin Tube

Extruded Aluminum Finned Tubes, also known as "Integral Finned Tubes". Integral finned tubes are manufactured by rolling process on tubes. During finning operation, the inside diameter of the tubes is reduced and helical fins are rolled on the tube wall. 

Extruded aluminum fin tube is rolled as an integrity with no thermal contact resistance, high intensity, featured in thermal shock and mechanical shock resistance. Heat exchangers assembled with this kind of fin tube (extruded fin type) is much better than the one equipped with string fin tubes or hectically wound fin tubes (L/LL/KL type fin).

Extruded Aluminum Finned Tubes, also known as "Integral Finned Tubes". Integral finned tubes are manufactured by rolling process on tubes. During finning operation, the inside diameter of the tubes is reduced and helical fins are rolled on the tube wall. The tubes material can be Copper Alloy, Brass Alloys, Copper Nickel Alloy, Titanium Alloy, Stainless Steel, Duplex Stainless Steel etc. The pressure required to extrude fins from the aluminum sleeve creates an excellent "pressure bond" between the two materials.

Copper and aluminum com-posited fin tubes are rolled from a muff copper tube, advantaged in tight link, small thermal resistance, good heat transfer efficiency, small flow loss and strong corrosion resistance. When working in long time under heating and cooling conditions, they are durable and not easy to deform.

The integral extruded fin tubes is smooth on surface and easy to clean. When wet cooling in heating and air conditioning project, it is easy to remove the condensation water on the outer surface of the fin, and it is not easy to dust and scale in the heating and other heat exchange.
