Many businesses that use seawater, such as shipping, offshore oil and gas production, power plants, and coastal industrial plants, use Copper Nickel Pipeline Systems.
Seawater is mostly utilized for cooling, but it also finds its way into oil field water injection, desalination plants, and firefighting.
Copper Nickel Pipeline Systems: What Are They?
Copper-nickel (Cu-Ni) pipeline systems consist of Copper Nickel Pipes, copper nickel pipe fittings, copper nickel flanges, and valves that connect seawater processing systems.
The two copper nickel alloys most commonly employed in these pipeline systems are 90-10 Cu-Ni and 70-30. They're used for three reasons: corrosion and bio fueling resistance, high strength, and inexpensive production costs.
Due to its great strength, 90-10 Cu-Ni is largely employed in submarines. Cu-Ni 70-30 is used in the remaining Cu-Ni applications.
While both materials are valuable, and designs must account for velocity and temperature, the current trend is to use 90-10 Cu-Ni instead of other alloys like aluminium brass, stainless steel, or others for the following reasons:
Cu-Ni alloys are stronger and have improved weldability.
Cu-Ni alloys have a good resistance to stress corrosion. After manufacturing, Cu-Ni alloys normally do not require any stress release heat treatment.
Cu-Ni alloys have a long history of dependability. In fact, in the last 20 years, just 9 cases of early failure have been published.
