copper nickel pipe fittings
What is copper nickel pipe fitting
90/10 copper-nickel (Cu90Ni10) pipe fittings, leveraging the advantages of their copper-nickel alloy ratio, possess excellent resistance to seawater corrosion, marine biofouling, crevice corrosion, and stress corrosion. They also exhibit outstanding thermal conductivity, good low-temperature toughness, are non-magnetic, easy to weld, and 100% recyclable. Compared to ordinary stainless steel, they offer greater adaptability, a longer service life, and superior cost-effectiveness.
Their core applications include marine and offshore oil and gas platforms, seawater desalination, coastal thermal and nuclear power plants, and chemical brine transportation. They are widely used in corrosive fluid piping systems such as seawater cooling, fire-fighting water supply, heat exchange condensation, and brine transportation.
Main product categories include standard pipe fittings such as copper-nickel pipes, elbows, tees, reducers, pipe caps, flanges, socket joints, pipe clamps, and threaded joints. Custom-made non-standard and irregular pipe fittings are also available to meet various pipeline turning, branching, diameter reduction, and sealing connection requirements.
