Large diameter 90/10 copper nickel pipe (UNS C70600) for offshore platforms, seawater cooling, fire protection, and desalination systems. It offers excellent corrosion and erosion resistance for marine applications.

C70600 copper nickel flanges in multiple sizes for marine and offshore applications. Excellent seawater corrosion and erosion resistance for ship piping, seawater cooling, and desalination systems.

C70600 CuNi 90/10 copper-nickel alloy offers excellent seawater corrosion resistance and erosion-corrosion resistance. The welding neck flange is butt-welded to the pipe, creating a reliable and durable connection for marine and seawater piping systems.

We supply a complete range of C70600 copper-nickel socket weld flanges, covering pressure ratings from Class 150 to Class 2500. Custom sizes are available, and EN 10204 3.1 material certificates are provided with shipment.

C70600 copper-nickel seamless pipes have long been used in marine systems—such as seawater cooling, fire-fighting, ballast, bilge, condenser, and heat exchange—due to their excellent corrosion resistance, resistance to biofouling, and good machinability a

C70600 copper-nickel alloy pipe fittings commonly include 45°/90° elbows, tees, reducers, flanges, caps, and various customized fittings. They are essential connection components in seawater piping systems for marine engineering applications.

C70600 and C71500 are two highly important materials in marine piping applications. Both offer excellent resistance to seawater corrosion, biofouling resistance, and long-term service stability.
