Extruded Fin Tube

Extruded Fin

SG-Extruded Fin (Bi-metallic Fin)

Application: High-efficiency fins for higher temperature applications giving complete and permanent atmospheric corrosion protection of the base tube. Using over 40% more aluminium than the equivalent applied fin, the extended fin is very robust and resistant to mechanical damage, allowing the finned tubes to be cleaned without damage using either steam or high-pressure water

Upper limiting temperature: 300°C

Manufacture: 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
