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 sanitary hot water, potable water, waste water or other fluids, in underground distribution networks.
The carrier pipe is made from cross-linked PE-Xa, colourless to a whitish colour. 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.
- Carrier pipes: PE-Xa/SDR 7.4/PN10
- Max fluid temperature: + 95 °C
- PE-X insulation foam: < 1% water absorption in accordance with ISO 2896
- Full coil length, all dimensions: 100 m
- Designed in accordance with European standard EN 15632-3
- CFC-free production process

(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.
The installation of adequately anchored Fix Points at the system’s extremities (typical at wall penetrations) is mandatory. This to secure the connected plumbing against the potential impact of the system’s dilatation forces (thermal expansion/retraction). Failing to do so involves a genuine damage risk, and automatically voids the system warranty.
To prevent ingress of (ground)water, the EN 15632-3 standard prescribes the usage of Shrink End Caps to seal the non-bonded system layers at underground connections. Failing to do so involves a genuine damage risk, and automatically voids the system warranty.
