RAUTHERMEX

REHAU RAUTHERMEX pre-insulated PE-Xa pipe was designed for applications where low heat losses are critical. This makes it ideal for large district heating and biomass systems over long distances. Lightweight polymer pipes such as RAUTHERMEX offer huge advantages over traditional steel pipework due to the speed and ease of installation.

RAUTHERMEX is available in UNO 25-160mm and DUO 25-75mm, completed with compression sleeve joints and the insulating shroud system, Tees, couplings and elbow jointing shrouds. The 75mm DUO product is suitable for a wider range of projects.

Materials

RAUTHERMEX district heating pipes are made of co-extruded, fully bonded layers, resulting in a system where expansion and contraction are controlled within the pipe system itself. (No linear expansion.) The UNO and DUO variants comprise one and two carrier pipes respectively, made of high-pressure cross-linked polyethylene (PE-Xa) in accordance with DIN 16892/93, SDR 11 with an EVOH oxygen diffusion barrier in accordance with DIN 4726. The thermal insulation is made of polyurethane (PU) and the outer jacket is made of polyethylene - low density (PE-LD).
