Overview
This document (EN 17878-1:2024) has been prepared by Technical Committee CEN/TC 107 "Preinsulated district heating pipe systems - Design and installation", the secretariat of which is held by Denmark (DS). The responsible German standardization committee is Working Committee NA 041-01-12 AA "Fernwärme- und Fernkälteverteilsysteme (SpA CEN/TC 107 & ISO/TC 341)" ("District heating and cooling systems (SpA CEN/TC 107 & ISO/TC 341)") at DIN Standards Committee Heating and Ventilation Technology and their Safety (NHRS).
This document specifies classification, general requirements and test methods for flexible, factory made, buried district heating pipe systems.
This document is intended to be used only in conjunction with EN 17878-2 or EN 17878-3, as applicable.
This document is applicable to a maximum operating temperature of 80 °C and a maximum operating design pressure up to 1,0 MPa.
The pipe systems are designed for a service life of at least 50 years. For pipe systems with plastic service pipes, the respective temperature profiles are specified in EN 17878-2:2024 and EN 17878-3:2024.
For the transport of other liquids, for example potable water, additional requirements can be applicable.
