Description
Engineered from a cupro-nickel alloy, this system pipe is purpose-built for demanding environments where salt water and corrosion present a constant challenge. Its high level of corrosion resistance makes it exceptionally well suited to pipelines carrying salt water, including saturated solutions up to 25%, as well as service, pool and heating water applications.
Certified for civil and military shipbuilding, drilling platforms, saltwater cooling systems and saltwater-operated sprinkler systems, it is a dependable choice for marine, offshore and industrial installations. Seamlessly drawn and finished with a protective cap.
Key Features & Benefits
- High corrosion resistance: Ideal for salt water and saturated saline solutions up to 25%.
- Smooth internal surface: A surface roughness of 10 µm promotes optimum flow behaviour and reduces the risk of internal fouling.
- Certified for demanding sectors: Approved for civil and military shipbuilding and drilling platforms.
- Wide size range: Available from DN12 to DN100 in standard 6m lengths to suit varied installation requirements.

(1) Usable negative pressure for Geberit piping systems: The usable negative pressure is calculated on the basis of the air pressure at the place of installation minus the absolute pressure of 200 mbar. Example: 980 mbar air pressure - 200 mbar absolute pressure = 780 mbar usable negative pressure in the piping system.
