Geberit Mapress CuNiFe for applications with seawater content
The seawater specialist
Shipbuilding and offshore applications are subject to extreme conditions. Piping systems in these areas not only have to function reliably but also ensure safety and resistance over many years.
The copper-nickel-iron alloy of Geberit Mapress CuNiFe has proven particularly effective in pipelines carrying seawater thanks to its excellent corrosion resistance.
Our comprehensive range of press-fitted piping systems includes system pipes and fittings with various seal rings.
Main applications and areas of use
Direct contact with seawater in shipbuilding and offshore applications, such as oil and gas rigs, places the highest requirements on corrosion resistance. This is exactly where Geberit Mapress excels thanks to its versatility.
Bilge
Geberit Mapress CuNiFe is suitable for pumping out bilge-water and routing it to separators to be treated.
Extinguishing water pipes
Geberit Mapress CuNiFe is perfect for both “wet” and “dry” sprinkler and extinguishing water pipes in maritime applications.
Seawater pipes
Corrosion-resistant CuNiFe pipes and fittings are suitable for various applications, including cooling, ballast water and desalination facilities.
Sanitary pipelines
The seawater used to supply toilets and fill swimming pools on cruise ships can be routed using Geberit Mapress CuNiFe.
Piping systems for shipbuilding
In addition to Geberit Mapress CuNiFe, the Geberit portfolio includes other piping systems and solutions for maritime use.
We also have a wide range of supply and drainage solutions for applications in other industries and sectors.
