Copper-nickel alloys are one of the most widely used alloys for various applications due to their good resistance to seawater corrosion, their effectiveness in lowering macrofouling levels, and their excellent workability. In addition, due to their high durability, antimicrobial properties, and appearance, they have become suitable for various purposes.

Copper-nickel 90/10 Pipes are commonly used in seawater pipes due to their full resistance to barnacles and marine organisms. Also, it is found to be efficiently used in other applications like condenser tubes or heat exchangers in the evaporator of the desalination plant, thermal power plant’s air cooling zone. It is also used in processing plants, seawater pipelines in ships, and high-pressure water heaters.

Advantages of using the Copper-nickel 90/10 pipes & tubes

• Due to the effectiveness in the production of Cu-Ni pipes and tubes it has become the best product that is having many good advantages to offer. The high-quality use of the alloy has led it to offer excellent qualities including high tensile strength, reuse, and excellent formability. In addition, it is very resistant to mechanical stress, increased resistance to high temperatures, and high resistance to high pressures.

Applications where Cu-Ni pipe & tube is used

• Shipbuilding and repair– copper and nickel alloy are used for seawater cooling, firefighting, and pneumatic and chiller system, bilge and ballast, and sanitary. They have also been found to be suitable for heating coils for loading tanks and for the supply line of desalination plants.
• Desalination plants–Cu-Ni is into the thermal desalination plant is very well established alloys. In MSF desalination, Copper-nickel 90/10 Tubes is used commonly for the recovery section and heat rejection and in brine heaters. Now, for MED, Cu-Ni alloy is used for tubing into the evaporator section.
• Power generation– Cu-Ni pipes and components can be easily used in the steam turbine condenser and oil coolers. In addition, it is used in high pressure preheaters of fossil fuel and nuclear power plants and in the auxiliary cooling system. They can also be used easily in conveying clean seawater, and brackish water. CuNi also offers greater advantages in marine renewable energies than tidal, wind farms, and waves.
• Seawater system Components– Cu-Ni condenser, tube sheets, heat exchangers, fittings, water boxes, piping, and pumps are a few essential components of a good quality seawater system design.
• Antimicrobial– Cu-Ni alloy is antimicrobial. Therefore, viruses, fungi, and bacteria cannot easily survive on the surface of CuNi products.
