Description
Engineered for demanding marine and industrial pipework, this stub flange is manufactured from a corrosion-resistant copper-nickel-iron alloy that performs reliably in systems carrying salt water, including saturated saline solutions of up to 25%. This stub flange is certified for civil and military shipbuilding, as well as for use in saltwater cooling systems and saltwater-operated sprinkler systems. Designed to work with a loose flange in accordance with EN 1092-1, flange type 02.
Key Features & Benefits
- Exceptional corrosion resistance: The copper/nickel/iron alloy withstands salt water and saturated saline solutions, making it ideal for marine and offshore environments.
- Certified for shipbuilding: Approved for civil and military shipbuilding and for use on drilling platforms.
- Secure flanged connection: The stub is designed for a loose flange, allowing straightforward connection to flanged valves, equipment and pipework.

(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.
