Abstract

1 Scope 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. This document does not apply to cover surveillance systems. NOTE For higher temperatures or for the transport of other fluids, for example potable water, additional requirements and testing is needed. Such requirements are not specified ...
