Description

Monel 400 Forged Flange Conforming to ASME B16.5 / ASME B16.47 Standards


Monel 400 forged flange is a high-performance nickel-copper alloy flange component with excellent corrosion resistance, particularly in seawater and chloride environments. It provides stable mechanical properties and reliable sealing performance under demanding service conditions.


Key Features

  • Excellent seawater corrosion resistance.
  • Good resistance to chloride stress corrosion cracking (SCC) .
  • Resistance to alkaline and salt solutions.
  • Excellent cryogenic toughness.
  • Non-magnetic structure.
  • Dense forged microstructure with high pressure capability.
  • Suitable for high-pressure sealing systems.


Common Types


Weld Neck Flanges (WN), Slip-On Flanges (SO), Blind Flanges (BL), Socket Weld Flanges (SW), and Threaded Flanges.


Typical Applications

  • Fluorine chemical industry and hydrofluoric acid equipment piping.
  • Seawater desalination and offshore platform seawater transmission systems.
  • Caustic soda and alkaline chemical processing plants.
  • Oil & gas desulfurization and chloride-containing corrosive pipelines.
  • Low-temperature equipment and various corrosive process piping systems.
