What is Copper Nickel Pipe Fittings?
To connect processing systems for handling seawater, copper-nickel (Cu-Ni) pipeline systems are made up of copper nickel pipes, copper nickel pipe fittings, copper nickel flanges, and copper-nickel valves.
The two copper-nickel alloys that are most frequently employed in these pipeline systems are 90-10 Cu-Ni and 70-30. They are used for precisely three reasons: resistance to corrosion and biofouling, high strength, and affordable manufacture. Due to its robustness, Copper Nickel 90/10 Pipe Fittings is widely utilized in submarines. Cu-Ni is used in 70-30 ratios for the remaining applications.
While both materials are valuable and designs must take temperature and velocity into account, the current trend is to employ 90-10 Cu-Ni rather than other alloys like aluminum, brass, or stainless steel for the following reasons:
- Cu-Ni alloys are stronger and better at welding.
- Cu-Ni alloys have great resistance to corrosion under stress. After manufacturing, stress relief heat treatment is typically not necessary for Cu-Ni alloys.
- The dependability of Cu-Ni alloys has been established. Only 9 instances of early failure have been documented in the past 20 years.
Characteristics of Copper Nickel Pipe Fittings
- Low usage in applications involving seawater or saltwater
- Seawater-based materials with high resistance to stress consumption cracking
- Due to chlorides, there is high resistance to erosion and stress consumption.
- Dependable pitting resistance.
- The simplicity of invention and welding.
Temperature of Copper Nickel Pipe Fittings
The moderate 15 KSI yield strength of 90/10 Cupro Nickel Pipe Fittings makes them appropriate for use in both low-temperature and high-temperature applications. Additionally, we are the leading stockholder of Copper Nickel ASTM B366 Pipe Fittings, including Cupro Nickel elbows, Cu-Ni 90-10 stub ends, Cu-Ni 90/10 tees, Cu-Ni 70/30 reducers, and Cu-Ni 70-30 crosses.
The 90-10 Copper Nickel Seamless Pipe Fittings have excellent overall resistance to seawater and copper-nickel possesses is well recognized. Due to its high alloy content, copper nickel fittings are frequently employed as piping system connections in the shipbuilding and power-generating sectors.
Applications of Copper Nickel Pipe Fittings
90/10 Copper Nickel Pipe Fittings for Shipbuilding – Special Marine Vessels, Offshore – Various Navy Projects, and Related Projects Numerous gauge options and a range of diameters are some of the primary characteristics of 70/30 Cupro Nickel Pipe Fittings.
