Description
RAUVIPEX DUO 63mm – 441033
RAUVIPEX DUO 63mm is a pre-insulated twin pipe system designed for high-capacity underground heating networks, carrying both flow and return lines within a single casing. It is commonly used in large district heating and biomass heating installations.
The twin-pipe configuration allows combined flow and return pipework to be installed within a single trench, reducing groundworks compared to separate pipe runs. The insulated construction supports thermal performance over long underground distances.
This size is typically selected for main underground distribution lines supplying multiple buildings or large heat loads from a central energy centre.
RAUVIPEX DUO 63mm is compatible with REHAU-approved jointing systems. It is commonly specified where long-term reliability and consistent underground performance are required.
