District heating pipes - Preinsulated bonded twin pipe systems for directly buried hot water networks - Part 1: Twin pipe assembly of steel service pipe, polyurethane thermal insulation and outer casing of polyethylene
This European Standard for District Heating Twin Pipes, specifies requirements and test methods for straight lengths of prefabricated thermally insulated pipe-in-pipe assemblies for directly buried hot water networks, comprising two steel service pipes from DN 15 to DN 250, rigid polyurethane foam insulation and one outer casing of polyethylene. The pipe assembly may also include the following additional elements: Measuring wires, spacers and diffusion barriers. This standard applies only to insulated twin pipe assemblies, for continuous operation with hot water at various temperatures up to 120 °C and occasionally with a peak temperature up to 140 °C and various internal pressures up to PN 16. The estimation of expected thermal life with continuous operation at various temperatures is outlined in annex B of EN 253.

In dieser Europäischen Norm für Fernwärme-Doppelrohrsysteme sind Anforderungen und Prüfverfahren für
gerade Abschnitte von werkmäßig gedämmten Rohr-in-Rohr-Systemen für direkt erdverlegte Fernwärmenetze
festgelegt, die aus zwei Stahl-Mediumrohren von DN 15 bis DN 250 mit einer Wärmedämmung aus
Polyurethan-Hartschaumstoff und einer Ummantelung aus Polyethylen mit kreisförmigem Querschnitt
bestehen. Das Verbund-Rohrsystem darf darüber hinaus folgende Bauteile umfassen: Messdrähte,
Abstandhalter und Diffusionsbarrieren.
Diese Norm gilt nur für wärmegedämmte Doppelrohrsysteme für den Dauerbetrieb mit Warmwasser bei unterschiedlichen
Betriebstemperaturen von bis zu 120 °C und gelegentlich auftretenden Spitzentemperaturen von
bis zu 140 °C.
Die Abschätzung der erwarteten thermischen Lebensdauer bei Dauerbetrieb mit unterschiedlichen Betriebstemperaturen
wird in EN 253, Anhang B erläutert.

La présente Norme européenne pour les bitubes de chauffage urbain définit les prescriptions et les méthodes
d’essais applicables aux longueurs droites de systèmes préfabriqués de tubes isolés thermiquement pour
réseaux d’eau chaude enterrés directement comprenant deux tubes de service en acier de DN 15 à DN 250,
une isolation en mousse rigide de polyuréthane et un tube de protection en polyéthylène. Le tube préisolé
peut également comprendre les éléments supplémentaires suivants : les câbles de mesure, les entretoises et
les barrières anti diffusion.
La présente Norme s’applique uniquement aux assemblages de bitubes isolés utilisés pour l’eau chaude à
différentes températures pouvant aller en service continu jusqu'à 120 °C et, parfois, à une température de
pointe pouvant atteindre 140 °C.
L’estimation de la durée de vie thermique escomptée de systèmes opérant à différentes températures en
service continu est donnée à l’Annexe B de l’EN 253.
