Pre-insulated double heating pipe

  • Hyper flexible, pre-insulated piping system, combining both the flow and the return medium pipes in the same jacket pipe, primarily intended for the transport of heating water or other media in buried distribution networks.

    The medium pipes are made from cross-linked polyethylene PE-Xa with an orange coloured oxygen-diffusion barrier for the flow line, and a blue coloured one for the return. The colour code enables easy identification of flow and return during installation, even with mounted dust or shrink end caps.

    The multilayer thermal insulation is made from cross-linked, microcellular polyethylene PE-X foam with a water-repellent closed cell structure, characterized by its durable, non-ageing insulation performance, and its
    permanent elasticity, maximizing and maintaining the thickness of the insulation layer, even after bending multiple times.

    The high-grade, black coloured UV-resistant, double walled, corrugated HDPE jacket pipe shields the pre-insulated piping system against mechanical impacts and moisture, whilst maintaining maximum flexibility.
