FibreFlex

An energy-efficient, pre-insulated flexible pipe system for heating applications.

Applications: Elevated pressure heating networks, small and mid-sized district heating networks

Description:

An innovative Thermoplastic Reinforced Service (TRS) pipe with PE-Xa liner and a high modulus aramid reinforcement mesh is used for FibreFlex pipes for maximum 10 bar operating pressure at continuous 80˚C operating temperature (application temperature profile according to EN 15632-2, OFI CERT ZG 200-2 Class A).

An oxygen barrier layer prevents oxygen diffusion into the network.

Due to reduced wall thickness, FibreFlex service pipes have smaller OD compared to conventional plastic solutions, which allows a thicker insulation layer with same casing dimensions. This, combined with the low thermal conductivity value of the cyclopentane-based PUR foam insulation 0.021 W/mK, makes FibreFlex pipes an outstanding, highly-energy-efficient solution for heating networks.

Use of FibreFlex pipes in applications with operating pressures lower than 10 bar provides a higher safety factor for heating pipe networks.

The FibreFlex pipe system is manufactured in accordance with OFI CERT ZG 200-2 Class A Technical Specification.
