Copper Nickel 70/30 Welded Pipe

Copper Nickel, also known as cupro nickel or CuNi, has proven to be very resistant to seawater, brine water, organic compounds, salts, diluted non-oxidizing acids, and more. Due to its complete resistance towards marine organisms such as barnacles, Copper Nickel tubing is commonly used in seawater piping systems.
