Copper-nickel orifice flanges find extensive applications in industries demanding accurate flow measurement and corrosion resistance. They are also found in marine environments, desalination facilities, and offshore oil and gas platforms because they exhibit high seawater and biofouling resistance. They facilitate differential pressure measurement helping in precise fluid flow control. Their ruggedness and compatibility with hostile environments enable them to find applications in chemical processing and power generation systems. Copper-nickel alloys are also resistant to thermal expansion providing consistent performance in varying temperatures and pressures.
