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;
— Part 2: Factory made fitting assemblies of steel or plastic service pipe, polyurethane thermal insulation and
a casing of polyethylene (this document);
— Part 3: Factory made steel valve assembly for steel or plastic service pipe, polyurethane thermal insulation
and a casing of polyethylene.
The other standards from CEN/TC 107 covering this subject are:
— EN 17414-1, District cooling pipes — Factory made flexible pipe systems — Part 1: Classification, general
requirements and test methods;
— EN 17414-2, District cooling pipes — Factory made flexible pipe systems — Part 2: Bonded system with

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 factory made thermally insulated
bonded fitting assemblies for directly buried district cooling distribution systems, comprising a service
fitting from DN 15 to DN 1200, rigid polyurethane foam insulation and a casing of polyethylene.
The fitting assembly can also include the following additional elements: measuring wires, spacers and
diffusion barriers.
This document covers the following fitting assemblies: bend, tee, reducer, cap and anchor.
This document applies only to insulated fitting 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.
NOTE An expected service life of 50 years presupposes that treated water is used.
