District heating pipes - Preinsulated bonded pipe systems for directly buried hot water networks - Fitting assemblies of steel service pipes, polyurethane thermal insulation and outer casing of polyethylene; German version prEN 448:2014

inactive
Organization: DIN
Publication Date: 1 April 2014
Status: inactive
Page Count: 36
ICS Code (Metal fittings): 23.040.40
scope:

Diese Europäische Norm legt Anforderungen an und Prüfverfahren für Formstücke von werkmäßig wärmegedämmten Verbundmantelrohren für direkt erdverlegte Fernwärmenetze fest, die aus einem Stahlformstück als Mediumformstück von DN 20 bis DN 1 200 mit Wärmedämmung aus Polyurethan-Hartschaumstoff und einer Ummantelung aus Polyethylen nach EN 253 bestehen.

Diese Norm behandelt folgende Formstücke: Bogenstücke, T-Stücke, Reduzierstücke, Einmalkompensator und Festpunktelemente.

Diese Norm gilt ausschließlich für werkmäßig gedämmte Verbundformstücke und Einmalkompensatoren für den Dauerbetrieb mit Warmwasser bei unterschiedlichen Betriebstemperaturen nach EN 253.

Diese Norm gilt für Verbundformstücke, die für einen Druck von mindestens 16 bar (Überdruck) nach EN 13941 ausgelegt sind.

Diese Norm enthält keine Regeln für die Berechnung von Last- und Spannungswerten. Die Regeln für Auslegung und Installation des Systems sind EN 13941 zu entnehmen.
