Description
Part of the Geberit Mapress CuNiFe system, this flanged stub with a plain end is manufactured from a copper, nickel and iron alloy (CuNi10Fe1.6Mn) that delivers exceptional resistance to corrosion. It is well suited to pipelines carrying salt water, including saturated saline solutions of up to 25%, as well as to the wider demands of shipbuilding and offshore installations.
The plain end is designed to work with a loose backing flange in accordance with EN 1092-1, flange type 02, giving a dependable, standards-compliant connection to flanged valves, equipment and adjoining pipework. The fitting is rated at PN6 and is offered in three nominal sizes, DN25, DN40 and DN65, to suit a range of applications.
The wider system is certified for civil and military shipbuilding and for use on drilling platforms, covering service, pool and heating water, saltwater cooling systems and saltwater-operated sprinkler systems.
Key Features & Benefits
- High corrosion resistance: The copper, nickel and iron alloy (CuNi10Fe1.6Mn) withstands salt water and saturated saline solutions of up to 25%, ensuring dependable performance in marine conditions.
- Ideal for shipbuilding and offshore use: Part of a range certified for civil and military shipbuilding and for drilling platforms, covering service, pool and heating water, saltwater cooling systems and saltwater-operated sprinkler systems.
- Standards-compliant connection: The plain end suits a loose backing flange to EN 1092-1, flange type 02, for a reliable compliant joint to flanged valves, equipment and pipework.
- PN6 pressure rating: Rated for pipework operating at pressures up to 6 bar.

(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.
