Réseaux d’eau glacée - Systèmes de tuyaux flexibles manufacturés - Partie 3 : Système non bloqué avec tube de service en plastique - prescriptions et méthodes d'essai

Le présent document spécifie les exigences et méthodes d’essai pour les tuyaux non bloqués 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 17414-1.
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 fondée sur une durée utile prévue en fonctionnement continu d’au moins 50 ans.
Le présent document ne couvre pas les systèmes de surveillance.
En conjonction avec les autres parties de l’EN 17414, le présent document est applicable aux tubes, aux raccords, aux joints et aux joints avec composants non constitués de matériaux plastiques destinés à être utilisés dans les installations de refroidissement urbain.
NOTE   Pour le transport d’autres liquides, par exemple de l’eau potable, des prescriptions supplémentaires peuvent s’appliquer.
