Description
RAUVIPEX DUO 32mm – 441027
RAUVIPEX DUO 32mm is a pre-insulated twin pipe system designed to carry flow and return lines within a single casing for underground heating pipework. It is commonly used in small to medium district heating networks.
The twin-pipe design allows flow and return pipework to be installed together, reducing excavation compared to separate single-pipe installations. The insulated construction helps maintain thermal performance along underground runs.
This size is typically selected for underground heating pipework connecting plant rooms to individual buildings or small groups of buildings where moderate heat demand is required.
RAUVIPEX DUO 32mm is compatible with REHAU-approved jointing systems. It is commonly specified where reliable underground heating pipework is required with reduced ground disturbance.
