Copper nickel flanges are widely used in various industrial applications due to their exceptional corrosion resistance and durability. Commonly found in marine environments, such as shipbuilding and offshore platforms, these flanges withstand the harsh conditions of seawater, including corrosion, erosion, and biofouling. Additionally, they are employed in desalination plants, chemical processing facilities, and power generation plants where reliable and long-lasting piping systems are crucial.
Copper nickel flanges are available in various sizes ranging from 1/2″ to 48″ and pressure ratings ranging from Class 150 to Class 2500, depending on the application’s specific requirements.
Yes, copper nickel is a recyclable material, making copper nickel flanges environmentally friendly and contributing to sustainability efforts.
Copper nickel flanges require minimal maintenance due to their corrosion resistance, but periodic inspections and cleaning may be necessary to ensure optimal performance and longevity.
Common types of copper nickel flanges include weld neck, slip-on, socket weld, threaded, lap joint, blind, and spectacle blind flanges, each suitable for specific installation methods and conditions.
