FibreFlex Pro is an innovative solution, enables the safe implementation of plastic flexible pre-insulated pipe systems in district heating networks with elevated operating temperatures and pressures, where previously, only steel pipes could be used.
An innovative Thermoplastic Reinforced Service (TRS) pipe with PEX-a liner and high modulus aramid reinforcement mesh is used for FibreFlex pipes for a maximum of 10 bar operating pressure and temperature up to 115˚C peak (application temperature profile according to OFI CERT ZG 200-2 Class C).
Due to reduced wall thickness, FibreFlex Pro service pipes have smaller OD compared to conventional plastic solutions, which allows a thicker insulation layer with same jacket dimensions. This, combined with the low value of the cyclopenthane-based PUR foam insulation thermal conductivity of ≤0.021 W/mK, makes FibreFlex Pro pipes an outstanding, highly-energy-efficient solution for heating networks.
