HeatFlex
A pre-insulated flexible pipe system for heating applications.
Cross-linked (peroxide method) polyethylene PE-Xa SDR 11 service pipe is used for HeatFlex pipes with maximum 6 bar operating pressure at 80˚C continuous operating temperature (application temperature profile according to EN 15632-2:2015).
EVOH barrier layer for service pipe prevents oxygen penetration into heating network.
Highly efficient cyclopenthane-based PUR foam insulation gives an excellent thermal conductivity value of 0.021 W/mK.
To accommodate the varying heat loss requirements of the pipe network, HeatFlex pipes are available with a range of insulation thickness options to suit the required performance specification.
The HeatFlex pipe system is manufactured in full accordance with EN 15632:2015 and OFI CERT ZG 200-1 Technical Specification.
