Product Description
ASME SB163 NO8825 Nickel Alloy Extruded Fin Tube Heat Exchanger For Heat Exchanger
Product Overview
The NO8825 Nickel Alloy Extruded Fin Tube is a nickel-iron-chromium alloy enhanced with molybdenum and copper. This specialized composition provides exceptional resistance to corrosive environments, outperforming Alloy 800 in water corrosion resistance.
Key Advantages
- Superior resistance to reducing and oxidizing acids
- Excellent protection against stress corrosion cracking
- Effective resistance to pitting and crevice corrosion
- Particularly resistant to sulfuric and phosphoric acids
Manufacturing Process
The aluminum fin strip is tension wound and precisely placed into a groove cut into the tube with approximately 0.4mm fluted depth, ensuring optimal heat transfer efficiency.
Applications
- Heat exchangers for power plants (electric, nuclear, thermal, geothermal)
- High corrosive systems (condensers, evaporators, desalination plants)
- Chemical processing equipment (fertilizer, urea, ammonia systems)
- Petroleum, chemical, and petrochemical industries
- Food processing and refrigeration systems
- Natural gas treatment facilities
