Double Heating

Double Heating

Product Description

Highly flexible, pre-insulated pipe systems, combining both the flow and the return carrier pipes in the same jacket pipe, primarily intended for the transport of heating water, or other heat-transfer media, in underground distribution networks.

 

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

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

The high-grade, double walled, corrugated HDPE sleeve shields the pre-insulated pipe system against mechanical impacts and moist, whilst maintaining maximum flexibility.
