Applications: Elevated temperature and pressure heating networks, large- and medium-size district heating networks.
Description:
An innovative Thermoplastic Reinforced Service (TRS) pipe with PE-Xa 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).
Both the service pipe and casing have diffusion barrier layers to prevent oxygen entering the system.
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 casing 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.
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.
