Copper Nickel Pipe and Tube

Copper Nickel Pipes and Tubes are a cost-effective and versatile option for various applications involving seawater, brackish water, and some acidic or caustic fluids.

The term “NB” refers to Nominal Bore, a designation related to the pipe’s diameter.

Schedules (5S, 10, etc.) specify the pipe wall thickness. Choosing the appropriate schedule depends on the pressure rating requirements of your application.

The form (Seamless, ERW, Welded) refers to the manufacturing method used to create the pipe/tube. Seamless pipes offer the highest strength but are generally more expensive.

Round and Square are the most common shapes available, although other shapes may be obtainable depending on the supplier.

The two available grades (Copper Nickel 90/10 and 70/30) cater to varying levels of corrosion resistance needs:

• • Copper Nickel 90/10 (Cu-Ni 90/10): Offers superior corrosion resistance, ideal for harsh environments like seawater.
  • Copper Nickel 70/30 (Cu-Ni 70/30): Provides a more economical option with good corrosion resistance, suitable for less severe applications.

When selecting Copper Nickel Pipe and Tube, consulting a specialist is recommended to ensure you choose the most suitable grade, schedule, and form for your project, considering factors like:

• Severity of the corrosive environment: The specific copper nickel grade should be chosen based on the type of fluid being transported and its corrosivity (e.g., 90/10 for seawater).
• Operating temperature: Copper Nickel grades generally perform well in moderate temperature ranges.
• Pressure requirements: The chosen grade, schedule, and wall thickness must meet or exceed your operating pressure for safe operation
