District cooling pipes - Factory made flexible pipe systems - Part 1: Classification, general requirements and test methods

This document specifies requirements and test methods for factory made thermally insulated flexible pipe-in-pipe assemblies for directly buried district cooling distribution systems, comprising a service pipe and a casing of polyethylene. The pipe assembly can also include the following additional elements: measuring wires, spacers and diffusion barriers.
This document is intended to be used in conjunction with EN 17414‑2 or EN 17414‑3.
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 dependent on material specified.
The design is based on an expected service life with continuous operation of a minimum 50 years. For pipe systems with plastic service pipes, the respective temperature profiles are defined in EN 17414‑2 and EN 17414‑3.
NOTE For the transport of other liquids, for example potable water, additional requirements could be applicable.

Fernkälterohre - Werkmäßig gefertigte flexible Rohrsysteme - Teil 1: Klassifikation, allgemeine Anforderungen und Prüfung

Dieses Dokument legt Anforderungen und Prüfverfahren für werkmäßig gefertigte, wärmegedämmte flexible Rohr-in-Rohr-Systeme für direkt erdverlegte Fernkältenetzwerke, bestehend aus einem Mediumrohr und einem Polyethylenmantel, fest. Das Rohrsystem kann darüber hinaus die folgenden zusätzlichen Bauteile umfassen: Messdrähte, Abstandshalter und Diffusionsbarrieren.
Dieses Dokument ist für die Verwendung im Zusammenhang mit EN 17414 2 oder EN 17414 3 vorgesehen.
Dieses Dokument ist nur anzuwenden für gedämmte Rohrsysteme, für den Dauerbetrieb mit Wasser bei verschiedenen Temperaturen 1 °C bis 30 °C und je nach Werkstoff einem Betriebsdruck von höchstens 25 bar.
Die Auslegung basiert auf einer erwarteten Lebensdauer von mindestens 50 Jahren bei Dauerbetrieb. Für Rohrsysteme mit Kunststoff-Mediumrohren sind die jeweiligen Temperaturprofile in EN 17414 2 und EN 17414 3 festgelegt.
ANMERKUNG   Für den Transport anderer Flüssigkeiten, z. B. Trinkwasser, könnten zusätzliche Anforderungen gelten.

Réseaux d’eau glacée - Systèmes de tuyaux flexibles manufacturés - Partie 1 : Classification, prescriptions générales et méthodes d'essai

Le présent document spécifie les exigences et méthodes d’essai pour les tuyaux à double enveloppe flexibles isolés thermiquement manufacturés pour réseaux de distribution d’eau glacée enterrés directement, comprenant un tube de service et un tube de protection en polyéthylène. Le tuyau préisolé peut également comprendre les éléments supplémentaires suivants : les câbles de mesure, les entretoises et les barrières anti diffusion.
Le présent document est destiné à être utilisé conjointement avec l’EN 17414-2 ou l’EN 17414-3.
Le présent document s’applique uniquement aux tuyaux préisolés conçus pour un fonctionnement continu avec de l’eau à diverses températures (allant de 1 °C à 30 °C) et à une pression de service maximale de 25 bar dépendant du matériau spécifié.
La conception est basée sur une durée utile prévue en fonctionnement continu d’au moins 50 ans. Pour les systèmes de tuyaux avec des tubes de service en plastique, les profils de température respectifs sont définis dans l’EN 17414-2 et l’EN 17414-3.
NOTE   Pour le transport d’autres liquides, par exemple de l’eau potable, des prescriptions supplémentaires peuvent s’appliquer.
