guishing agent flows through the downstream pipework to the discharge nozzles where it
escapes into the extinguishing zone.

For information pertaining to system racking, See “Appendix A - Racking Assembly” on
page 183.
4.3 Pipeline system
Pipes and fittings make up the pipeline system between the extinguishing agent cylinders
and discharge nozzles. This is an optional portion of the scope of delivery.
The pipeline system for Oxeo inert gas extinguishing systems is divided into two different
areas:
•
High pressure pipework: The area of the high-pressure pipework starts at the manifold and
ends at the pressure reducer. The selector valves and manifold pipes are also located in the
high-pressure pipework for multi-zone systems.
•
Downstream pipework: The area of the downstream pipework starts behind the pressure
reducer and ends at the nozzles.
The design of the pipeline system including the required pipe cross sections must be exe-
cuted through a hydraulic calculation program recognized by the manufacturer. The pipeline
serves as the basis here.
Changes in the pipeline routing require a new hydraulic calculation. In this regard changes in pipe
cross section, extinguishing agent cylinder size, pressure reducer bezel, and nozzle bores can occur.
The manufacturer provides technical specifications for materials made available for the pipeline sys-
tem. A checking of the materials for matching with local guidelines for pressurized pipelines and
their corresponding selection is the responsibility of the Authorized Distributor.
