90/10 copper nickel pipe, also known as C70600 copper nickel pipe, CuNi 90/10 pipe or CuNi10Fe1Mn pipe, is a copper nickel alloy pipe containing approximately 90% copper and 10% nickel, with small additions of iron and manganese to improve corrosion resistance and strength in seawater environments.

C70600 copper nickel pipe is widely used in marine engineering because it forms a stable protective surface film in flowing seawater. This makes it highly suitable for long-term service in seawater cooling systems, fire water systems, ballast systems, bilge systems, desalination plants and offshore piping systems.

Compared with many other metallic piping materials, 90/10 copper nickel pipe offers a good balance of corrosion resistance, workability, weldability and service life, making it a preferred choice for marine seawater applications.

We supply 90/10 copper nickel pipes in seamless and welded types, manufactured according to ASTM, DIN, EN, EEMUA and project specifications. Custom sizes, lengths, end finishes and inspection requirements are available upon request.

General Supply Range

90/10 Copper Nickel Pipe vs 70/30 Copper Nickel Pipe

Both 90/10 and 70/30 copper nickel pipes are used for seawater piping systems. The main difference is the nickel content and performance under more demanding service conditions.

90/10 copper nickel pipe C70600 is commonly selected for general marine seawater systems due to its excellent performance and cost efficiency. 70/30 copper nickel pipe C71500 is preferred for more demanding conditions where higher strength and better resistance to high-velocity seawater are required.

Matching Copper Nickel Pipe Fittings

We can also supply complete copper nickel pipe fittings for C70600 pipe systems, including:

• Copper nickel elbows

• Copper nickel tees

• Copper nickel reducers

• Copper nickel flanges

• Copper nickel caps

• Copper nickel stub ends

• Copper nickel couplings

• Copper nickel unions

• Fabricated copper nickel pipe spools

Custom copper nickel fittings according to drawings

Supplying pipes and fittings together helps ensure material compatibility, dimensional matching and easier project installation.

Quality Control and Inspection

Available inspections include:

• Chemical composition analysis

• Mechanical property test

• Visual inspection

• Dimensional inspection

• Wall thickness inspection

• Surface quality inspection

• Hydrostatic test

• Eddy current test

• Ultrasonic test

• PMI material verification

• Flattening test

• Flaring test

• Weld inspection for welded pipes

• Material test certificate

• Third-party inspection

• Classification society inspection if required
  
  

Packaging and Delivery

90/10 copper nickel pipes are packed carefully to prevent damage, deformation, scratching and contamination during transportation. Standard export packaging includes wooden cases, wooden pallets, plastic wrapping, end caps and seaworthy packing.

For long pipes, each bundle can be strapped securely and protected with plastic film or waterproof material. Pipe ends can be protected with caps or covers according to customer requirements.
