Copper Nickel Spectacle Flanges are built for decisive flow control in demanding marine and industrial environments. Manufactured from corrosion-resistant copper nickel alloys, these flanges deliver exceptional strength, long service life, and outstanding resistance to seawater, biofouling, and aggressive media. Their distinctive spectacle design allows quick switching between open and closed pipeline conditions, ensuring safe isolation during maintenance and inspection. Precision-machined for reliable sealing and structural stability, they perform confidently under pressure and temperature variations. Widely used in shipbuilding, offshore platforms, desalination plants, and power systems, Copper Nickel Spectacle Flanges combine durability with control—strong, dependable, and engineered to perform without compromise.
Copper Nickel Spectacle Flanges made of copper-nickel consist of a mixture of Cu and Ni in the usual concentration of 90% Cu-10% Ni exhibiting maximum corrosion resistance when used in aquatic and harsh conditions. The material has good tensile strength as high as 550 MPa, commonly achieved, and desirable ductility permitting easy shaping. They exhibit good physical resistance towards biofouling, improved stress corrosion crack resistance, and high thermal conduction. Copper-nickel spectacle flanges are resistant to pitting and crevice corrosion, with durability, and thus they are suitable for seawater and chemical industry applications.
