Extruded Finned Tube
Application: High-efficiency extruded fin tube is for higher temperature applications giving complete and permanent atmospheric corrosion protection of the base tube. Using over 40% more aluminum than the other kinds of finned tube the extruded fin is very robust and resistant to mechanical damage, allowing the finned tubes to be cleaned without damage when be used in either steam or high-pressure water.
Upper limiting temperature: 300°C
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.
Base Tube Diameter: 10mm-51mm
Base tube wall thickness: 1.65mm-3mm
Fin Thickness: 0.3mm-1.2mm
Fin Pitch: 2mm-15mm
Fin Height: 5mm-16mm
Base tube material:
Stainless steel, Carbon steel, Alloy, Titanium, Nickel, Copper etc.
Aluminum strip, Copper strip
The common application fields are:
1. Heat exchangers units for power plant (electric, nuclear, thermal and geothermal power plants);
2. High corrosive systems (condensers, evaporators, sea water desaltinations, fertilizing, urea systems, ammonia, gas, corrosive acids);
3. The petroleum, chemical and petrochemical industries;
4. The food processing and refrigeration industries;
5. Natural gas treatment.
