(1) The indicated minimum Bending Radius can be applied permanently without affecting the system’s quality or performance
(2) The Water Content is expressed in liters per meter length of pre-insulated pipe, including flow + return volume (gal.us / 100′ : 3/4″ = 5.3, 1″ = 8.7, 1-1/4″ = 13.4, 1-1/2″ = 21.0, 2″ = 33.4, 2-1/2″ = 23.8, 3″ = 34.3, 3-1/2″ = 51.2, 4″ = 66.1 )
(3) Average Heat Capacity in kW for the carrier pipe (at Twater of 80°C with a Δ T of 20°C)
(4) The U-value enables easy heat loss calculation, as a function of the driving temperature difference

CONNECTORS & ACCESSORIES
Please, contact us for other dimensional combinations or for the integration of specific pipes and/or components.
Highly flexible, pre-insulated pipe systems, can 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 waterrepellent closed cell structure, characterised by its durable, non-ageing insulation performance, and its permanent elasticity, maximizing the thickness of the insulation layer, even after bending multiple times.
The high-grade, double walled, corrugated HDPE sleeve shields the pre-insulated pipe system against mechanical impacts and moisture, whilst maintaining maximum flexibility.
