Copper-nickel pipes come in various sizes to meet industrial demands, particularly in marine and seawater handling applications. These pipes typically have outer diameters (OD) ranging from 1/8 inch to 24 inches, accommodating both small-scale and large-scale installations. The wall thickness is categorized using schedule numbers such as Sch 10, Sch 40, and Sch 80, which indicate the pipe’s thickness and pressure-bearing capacity. Pipes with higher schedule numbers have thicker walls and can withstand greater pressures.

Pipe Length and Types
Copper-nickel pipes are generally available in standard lengths of 6 meters (20 feet) or 12 meters (40 feet), though they can be customized based on project requirements. They come in two primary types:
Seamless pipes
Ideal for high-pressure environments due to their superior strength and durability.
Welded pipes
More cost-effective and suitable for lower-pressure applications.
Material Composition and Corrosion Resistance
Copper-nickel alloys are well known for their excellent resistance to seawater corrosion, anti-biofouling properties, and durability against erosion-corrosion, making them ideal for harsh marine conditions. The two most common alloy compositions are:
Cu-Ni 90/10 (90% copper, 10% nickel) – Offers good corrosion resistance and cost-effectiveness.
Cu-Ni 70/30 (70% copper, 30% nickel) – Provides superior strength and corrosion resistance for more demanding environments.
End Types and Connection Options
Copper-nickel pipes are available with different end types to suit various piping system connections:
Plain Ends (PE) – For welding or flanged connections.
Beveled Ends (BE) – Typically used for butt-weld joints.
Threaded Ends (TE) – Designed for threaded fittings.
Choosing the Right Pipe Size
When selecting the appropriate copper-nickel pipe size for a project, consider factors such as:
Required flow rate
Ensures optimal system performance.
Pressure rating
Determines the necessary wall thickness and schedule.
Environmental conditions
Helps select the right alloy for corrosion resistance and longevity.
By understanding these size specifications and selection criteria, you can ensure the proper performance and durability of copper-nickel pipes in any application. For precise dimensions, refer to a copper-nickel pipe size chart to match project requirements effectively.
