Product Description

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 include:

  • 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
