This document specifies classification, general requirements and test methods for flexible, factory made, buried district heating pipe systems with thermoplastic reinforced service pipes (TRSP).
The factory made bonded or non-bonded flexible pipe systems covered by this document consist of:
— a thermoplastic reinforced service pipe, which consists of an inner layer made of PE-Xa, a thermoplastic intermediate layer, a reinforcement layer made of para-aramid fibres, an outer thermoplastic layer and a diffusion barrier layer, all with bonded structure;
— a thermal insulation layer;
— a casing made of PE.
Depending on the temperature profile, this document is applicable to a maximum operating temperature of 115 °C and maximum operating design pressure up to 1,6 MPa.
The pipe systems are designed for a service life of at least 30 years.
