District heating pipes - Factory made flexible pipe systems - Part 4: Bonded system with metal service pipes; requirements and test methods
This document provides requirements and test methods for flexible, factory made, buried district heating pipe systems with metallic service pipes and bonding between the layers of the pipe assemblies and thermal insulation materials of polyurethane or polyisocyanurate foam, the casing being made of polyethylene.
It shall be used in conjunction with part 1.
This document is valid for maximum media temperatures up to 120 °C and, occasionally peak temperatures up to 140 °C for maximum 300 h/a, and a design pressure up to 2,5 MPa for a design lifetime of at least 30 years.
This document covers surveillance systems.
In conjunction with the other parts of EN 15632, this document is applicable to pipes, fittings, their joints and to joints with components made of non-plastics materials intended to be used for district heating installations.
NOTE For higher temperatures or for the transport of other fluids, for example potable water, additional requirements and testing is needed. Such requirements are not specified in this document.

Dieses Dokument gilt für eine maximale Medientemperatur von 120 °C, gelegentlich auftretende Temperaturspitzen bis 140 °C für maximal 300 h/a sowie für einen zulässigen Betriebsdruck bis einschließlich 2,5 MPa für eine Auslegungslebensdauer von mindestens 30 Jahren.
Dieses Dokument gilt für Überwachungssysteme.
Zusammen mit den anderen Teilen von EN 15632 gilt dieses Dokument für Rohre, Formstücke, ihre Verbindungen untereinander sowie mit Rohrleitungsteilen, deren Werkstoffe nicht aus Kunststoff bestehen und die für Fernwärmeinstallationen vorgesehen sind.
ANMERKUNG Für höhere Temperaturen oder für den Transport anderer Flüssigkeiten, z. B. Trinkwasser, sind zusätzliche Anforderungen und Prüfungen erforderlich. Derartige Anforderungen sind in diesem Dokument nicht festgelegt.
Tuyaux de chauffage urbain - Systèmes de tuyaux flexibles préisolés - Partie 4 : Système bloqué avec tubes de service en métal ; exigences et méthodes d'essai
Le présent document fournit les exigences et les méthodes d’essai relatives aux systèmes de tuyaux de chauffage urbain flexibles manufacturés enterrés avec des tubes de service en métal, une adhérence entre les couches des assemblages de tubes et des matériaux d’isolation thermique en mousse de polyuréthane ou de polyisocyanate ; les tubes de protection doivent être en polyéthylène.
Il doit être utilisé conjointement avec la partie 1.
Le présent document s’applique à des températures maximales de fluide de 120 °C et, occasionnellement des températures de fusion maximales de 140 °C pour une durée maximale de 300 h/a, et des pressions de conception maximales de 2,5 MPa, pour une durée de vie prévue d’au moins 30 ans.
Le présent document couvre les systèmes de surveillance.
Le présent document s’applique conjointement avec les autres parties de l’EN 15632 aux tuyaux, raccords, leurs joints, et aux joints avec des composants en matériaux non plastiques destinés à être utilisés pour les installations de chauffage urbain.
NOTE Pour les températures plus élevées ou pour le transport d’autres fluides, par exemple, de l’eau potable, des exigences et des essais supplémentaires sont nécessaires. Ces exigences ne sont pas spécifiées dans le présent document.

This document is currently submitted to the CEN Enquiry.This document will supersede EN 15632-4:2009.
This document is one of a series of standards which form several parts of EN 15632, District heating
pipes — Factory made flexible pipe systems:Part 1: Classification, general requirements and test methods;
Part 2: Bonded system with plastic service pipes; requirements and test methods;
Part 3: Non bonded system with plastic service pipes; requirements and test methods;
Part 4: Bonded system with metal service pipes; requirements and test methodsIn comparison to EN 15632-4:2009 the following changes have been made:
a) change the temperature in the scope;
b) changes in the mild steel qualities incl. the referring standards;
c) completely revised “guideline for testing” in the informative Annex A.
