District heating pipes - Preinsulated bonded pipe systems for directly buried hot water networks - Pipe assembly of steel service pipe, polyurethane thermal insulation and outer casing of polyethylene

This European Standard specifies requirements and test methods for straight lengths of prefabricated thermally insulated pipe-in-pipe assemblies for directly buried hot water networks, comprising a steel service pipe from DN 15 to DN 1200, rigid polyurethane foam insulation and an 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 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.
The estimation of expected thermal life with continuous operation at various temperatures is outlined in Annex B.

Fernwärmerohre - Werkmäßig gedämmte Verbundmantelrohrsysteme für direkt erdverlegte Fernwärmenetze - Verbund-Rohrsystem, bestehend aus Stahl-Mediumrohr, Polyurethan-Wärmedämmung und Außenmantel aus Polyethylen

Diese Europäische Norm legt Anforderungen und Prüfverfahren für vorgefertigte, gerade wärmegedämmte Rohr in Rohr Systeme für direkt erdverlegte Fernwärmenetze fest, die aus einem Stahl-Mediumrohr von DN 15 bis DN 1200 mit Wärmedämmung aus Polyurethan Hartschaumstoff und einer Ummantelung aus Polyethylen bestehen. Das Verbund Rohrsystem darf darüber hinaus folgende Bauteile umfassen: Mess¬drähte, Abstandshalter und Diffusionsbarrieren.
Diese Norm gilt nur für wärmegedämmte Verbund Rohrsysteme für den Dauerbetrieb mit Warmwasser bei unterschiedlichen Betriebstemperaturen von bis zu 120 °C und gelegentlich auftretenden Spitzen¬temperaturen von bis zu 140 °C.
Die Abschätzung der erwarteten thermischen Lebensdauer bei Dauerbetrieb mit unterschiedlichen Betriebs-temperaturen ist in Anhang B erläutert.

Tuyaux de chauffage urbain - Systèmes bloqués de tuyaux préisolés pour les réseaux d'eau chaude enterrés directement - Tube de service en acier, isolation thermique en polyuréthane et tube de protection en polyéthylène

La présente Norme européenne définit les prescriptions et les méthodes d’essai applicables aux longueurs droites de systèmes préfabriqués de tuyaux isolés thermiquement pour réseaux d’eau chaude enterrés directement comprenant un tube de service en acier de DN 15 à DN 1200, une isolation en mousse rigide de polyuréthane 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.
La présente Norme s’applique uniquement aux systèmes isolés par mousse de polyuréthane 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.

Cevi za daljinsko ogrevanje - Izolirani vezani cevni sistemi za podzemeljska toplovodna omrežja - Cevni sestav iz jeklene cevi, poliuretanske toplotne izolacije in zunanjega polietilenskega plašča

Ta evropski standard določa zahteve in preskusne metode za ravne odseke predizdelanih toplotno izoliranih cevnih sestavov za podzemeljska toplovodna omrežja, sestavljene iz jeklene cevi velikosti od DN 15 do DN 1200, izolacije iz trdne poliuretanske pene in zunanjega polietilenskega plašča. Cevni sestav lahko vključuje tudi naslednje dodatne elemente: merilne žice, distančnike in difuzijske pregrade. Ta standard se uporablja samo za izolirane cevne sestave za neprekinjeno delovanje s toplo vodo pri različnih temperaturah do 120 °C, včasih pa tudi z najvišjo temperaturo do 140 °C. Ocena pričakovanega življenjske dobe pri neprekinjenem delovanju pri različnih temperaturah je navedena v dodatku B.
