Shihang , copper nickel pipe manufacturer , maintains a broad inventory of Copper Nickel Flange C70600 (90/10) and C71500 (70/30) pipes. Copper Nickel has proven to be very resistant to seawater, brine water, organic compounds, salts, diluted non-oxidizing acids, and more. Due to a high resistance towards marine organisms such as barnacles, Copper Nickel is commonly used in seawater piping systems and oil piping systems

Cupro Nickel Pipes

Cupronickel or copper nickel is the copper alloy which contains nickel as well as strengthening elements like manganese and iron. In spite of its increased copper content, cupro nickel pipes are silver in color.

A copper-nickel alloy is comprised of nickel and copper as its basic elements and without or with some other elements like zinc might be present by below 1%. Together with other elements, nickel will be added within the highest concentration following copper. Aside from nickel and copper, most industrial Cu-Ni alloys is likewise comprised of iron, manganese and tin so as to improve some features and casting alloys is comprised of silicon and niobium.

This copper alloy shows copper nickel pipe corrosion resistance in the seawater. Due to that, it can be used for piping systems, marine hardware, and for crankshafts, propellers, fishing boats, and hulls of the premium tugboats, including other forms of working boats. The cupronickel alloy technology was already known by people, especially the Chinese for a very long period of time until today. Cupro nickel pipes were used since the 3rd century BC, using the name white copper and with its resistance to corrosion, it was used in mostly corrosive environments.

Copper nickel is still in use for modern boat making. It’s uniquely qualified as a suitable candidate for the piping systems within the boat building industry because of its very own alloy properties which involve low generation corrosion rates in the sea water, resistance to pressure corrosion cracking because of ammonia in the seawater, extreme crevice corrosion resistance and stress corrosion because of chlorides, fine pitting resistance, ease of construction, inherent resistance to biofouling and ready weldability. You just need to gather the correct information about the copper nickel pipe welding procedure.

Copper Nickel Pipe Applications 

Because of the specific copper nickel properties, this alloy of copper is used in different industries that include:

  • Armanents industry
  • Mint industry
  • Desalination industry
  • Electrical, petrochemical and chemical
  • Marine engineering
  • shipment building

Cupro Nickel is extremely resistant to corrosion in the water for the reason that the electrode potential of it has been adjusted to become neutral in connection with seawater. In this reason, copper nickel is used for heat exchangers, piping and condensers in the seawater systems.
