This document (EN 17415-1:2020) has been prepared by Technical Committee CEN/TC 107
“Prefabricated district heating and district cooling pipe systems”, the secretariat of which is held by DS.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by January 2021, and conflicting national standards shall
be withdrawn at the latest by January 2021.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,

Introduction
Factory made bonded single pipe systems for directly buried district cooling networks are of common
technical usage. In order to ensure quality including product-related service life, to ensure safety in use,
economical energy usage and to facilitate comparability in the market, CEN/TC 107 decided to set up
standards for these products.
This document is one of a series of standards which form several parts of EN 17415, District cooling
pipes – Bonded single pipe systems for directly buried cold water networks:
— Part 1: Factory made pipe assembly of steel or plastic service pipe, polyurethane thermal insulation
and a casing of polyethylene (this document);
— Part 2: Factory made fitting assemblies of steel or plastic service pipe, polyurethane thermal insulation
and a casing of polyethylene ;
— Part 3: Factory made steel valve assembly for steel or plastic service pipe, polyurethane thermal
1;
insulation and a casing of polyethylene
The other standards from CEN/TC 107 covering this subject are:

requirements and test methods;
— EN 17414-2, District cooling pipes - Factory made flexible pipe systems - Part 2: Bonded system with
plastic service pipes - Requirements and test methods;
— EN 17414-3, District cooling pipes - Factory made flexible pipe systems - Part 3: Non bonded system
with plastic service pipes - Requirements and test methods;
— EN ZZZZZ-1, District cooling pipes – Design and installation of thermal insulated bonded single and

twin pipe systems for directly buried cold water networks – Part 1: Design
— EN ZZZZZ-2, District cooling pipes – Design and installation of thermal insulated bonded single and
twin pipe systems for directly buried cold water networks – Part 2: Installation ;
— EN 489-1, District heating pipes - Bonded single and twin pipe systems for buried hot water networks -
Part 1: Joint casing assemblies and thermal insulation for hot water networks in accordance with
EN 13941-1;

Waste management and recycling of materials is dealt with in Annex C.

Under development.
1 Scope
This document specifies requirements, design and test methods for straight lengths of factory made
thermally insulated pipe-in-pipe assemblies for directly buried district cooling distribution systems,
comprising a service pipe from DN 15 to DN 1200, rigid polyurethane foam insulation and a casing of
polyethylene. The pipe assembly can also include the following additional elements: measuring wires,
spacers and diffusion barriers.
This document applies only to insulated pipe assemblies, for continuous operation with water at
various temperatures (1 to 30) °C and a maximum operation pressure of 25 bar.
The design is based on an expected service life with continuous operation of a minimum 50 years.
