C70600 CU-NI 90/10 Copper Tube
ASTM B466 C70600 Copper Nickel Pipes
What are Copper Nickel Pipes and Tubes?
Copper Nickel Pipes are wrought alloys with a mixture of copper and nickel. It has excellent corrosion resistance and superior strength and machinability. Copper Nickel Pipes are particularly well suited for marine applications. The corrosion resistance of copper-nickel pipes is remarkably high, and they are also very suitable for cryogenic applications.
Copper Nickel Tube products are available in various types and specifications. Copper-nickel 90/10 Pipes and Tubes and Copper-nickel 70/10 pipes and tubes are available in seamless and welded construction. Typical applications include seawater tube work, heat exchangers, and hydraulic lines. Copper Nickel products are also used in marine and offshore oil and gas applications. In addition to marine and industrial applications, they are also used for evaporators, heat exchangers, and chillers.
What are Copper Nickel Pipes?
Copper Nickel Pipes are pipes made of copper nickel alloy that have excellent corrosion resistance properties making them suitable for use in marine and coastal environments. Copper Nickel Alloy exhibits superior corrosion resistance and is commonly used in marine hardware and piping systems.
What are the Uses of Copper Nickel tubes?
Cupro Nickel Tubes are commonly used in marine & offshore applications, water treatment plants, desalination plants, chemical processing plants, and Power Generation Copper-nickel pipes and components can be used in steam turbine condensers, oil coolers, auxiliary cooling systems, and high-pressure pre-heaters at nuclear and fossil fuel power plants.
Cupro Nickel Tubes have excellent corrosion resistance properties, high strength & durability, and are suitable for use in high-temperature and high-pressure environments. The high quality of alloy utilization has led it to offer excellent qualities including high tensile strength, reusable, and excellent formability. Also, it is highly resistant to mechanical stresses, greater resistance to high temperature, and high resistance to high pressure.
