Pipe PE-Xa [32/125] [DN25] RAUVIPEX UNO (14410051001) 1m

The use of polymer pipe systems allows for the accelerated expansion of urban air conditioning networks, thus contributing substantially to the ecological transformation of energy supply towards climate neutrality. The decisive factors for the acceptance of products and system solutions are their technical suitability for the specific application and their ease of use. In this context, REHAU has developed the new RAUVIPEX piping system – a multi-purpose system for transporting heat and cold.

The new RAUVIPEX pipe system is characterized, in the category of flexible pipes with PU foam, by an excellent combination of insulating effect, robustness, and processing flexibility, thus establishing a new standard. It is ideal for connecting heat pumps in individual buildings, building networks, and district and urban air conditioning systems, especially with its increasing use in existing buildings.

The properties of the materials used in the pipes and pipe fittings are a decisive factor for the service life, safety, and profitability of heating networks. With RAUVIPEX, the patented longitudinally sealed pipe connection also ensures maximum safety during installation and operation. And finally, the clip and retractable sleeves are certified as watertight under the most stringent testing requirements.

• Highly thermally stabilized, cross-linked polyethylene (PE-Xa) pipe for district heating and cooling, externally tested according to EN 15632, DIN 16892/93 and ISO 15875-5, with an orange-marked EVOH oxygen diffusion barrier according to DIN 4726.
• Completely closed-cell longitudinal water barrier.
• Continuously manufactured polyurethane foam insulation for increased flexibility.
• Flexible and highly resistant profiled outer casing made of seamless extruded polyethylene (PE).

Pressure and temperature resistance. Maximum pressure and minimum service life under continuous operating temperature for REHAU PE-Xa SDR 11 thermal energy supply pipes according to EN 15632.
