Material Composition:
Copper Nickel 70/30 flanges are made from an alloy consisting of 70% copper and 30% nickel. This composition imparts specific properties to the material, such as enhanced resistance to corrosion, erosion, and biofouling in marine environments.
Corrosion Resistance:
One of the main benefits of the Copper Nickel 70/30 flange is its excellent corrosion resistance. This property is critical in applications where the flanges come in contact with seawater or other corrosive fluids. The copper content provides corrosion resistance, while the nickel content increases overall durability.
Applications:
Copper Nickel 70/30 flanges are used in a variety of industries, including offshore engineering, petrochemicals, chemical processing, and desalination plants. They are often used in piping systems where resistance to saltwater corrosion is critical, such as shipbuilding, offshore oil and gas platforms, and heat exchangers.
Mechanical Properties:
The alloy exhibits good mechanical properties, including high strength and ductility. This makes the 70/30 Copper Nickel flange suitable for withstanding the stresses encountered in pressure vessels and various industrial environments.
