Description
Extruded fin tubes are produced by inserting a carbon steel seamless tube into an aluminum sleeve, which is then extruded to form solid, integral fins with excellent metallurgical bonding. This design provides superior heat transfer efficiency, high mechanical strength, and resistance to fin detachment, making it ideal for Heat Recovery Steam Generator (HRSG) systems and other high-performance heat exchangers.
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
Strong fin-to-tube bond ensuring high heat transfer efficiency
Excellent vibration and corrosion resistance
Suitable for high-temperature and continuous operation in HRSG systems
Long service life and minimal maintenance requirements
Applications:
HRSG (Heat Recovery Steam Generator)
Air Cooled Heat Exchangers
Condensers and Waste Heat Recovery Units
Petrochemical and Power Generation Plants
