Description
Extruded fin tubes are manufactured by inserting a carbon steel core tube into an aluminum sleeve, which is then extruded to form solid fins with excellent metallurgical bonding. This structure ensures superior heat transfer performance, high mechanical strength, and corrosion resistance.
ASTM A179 carbon steel extruded fin tubes with Al1060 fins are widely used in condensers and air-cooled heat exchangers, providing efficient and durable thermal performance.
Manufacturing Process
A smooth core tube is inserted into an aluminium sleeve, after which the fins are integrally formed by extruding the aluminium outward from the sleeve.
Fin Types
Fins can be supplied either as solid plain or serrated, segmented into 12, 16, or 24 sections, or customized according to specific design requirements.
Unfinned Section
Both ends of the tube are left plain, typically 10 mm to 50 mm, with optional unfinned gaps in the middle section.
Surface Coating
The bare ends of the bimetallic finned tubes are coated with zinc or aluminium, applied using an electro-spray arc metallizing process for enhanced protection.
Advantages Comparied with Other Types of Fin Tube
Excellent fin-to-tube bond for maximum heat transfer efficiency
Strong mechanical integrity, suitable for vibration-prone environments
Improved corrosion resistance due to aluminum fins
NDT available to ensure quality and reliability
Applications:
Condensers
Air Cooled Heat Exchangers
