Cunifer is the catchall colloquial name for an alloy of copper (Cu), nickel (Ni), iron (Fe) rendered CuNiFe in proper molecular notation. This particular CuNi alloy is often used for pipes in the maritime sector. At we supply CuNi pipes for heat exchangers, fire extinguishing piping systems, sprinkler systems and cooling water systems.

Various applications for Cunifer in industrial piping

Cunifer piping is widely used in marine applications, offshore installations and shipbuilding industry. While the sea water environment is highly corrosive, CuNi pipes are very suitable in this environment. In addition, the copper content gives CuNi alloys anti-fouling properties. Their properties of anti-fouling and high corrosion protection make them a very economic choice to use in salt sea water systems. These seamless pipes are an excellent choice for both static and flowing fresh seawater environments.
