Preinsulated bonded pipe systems for underground hot water networks - Fitting assemblies of steel service pipes, polyurethane thermal insulation and outer casing of polyethylene
This European Standard specifies requirements and test methods for fittings of prefabricated thermally insulated pipe-in-pipe assemblies, comprising a steel service fitting from DN 20 to DN 600, rigid polyurethane foam insulation and an outer casing of high density polyethylene. However the quality requirements can be applied for larger dimensions.
Werksmäßig gedämmte Verbundmantelrohrsysteme für erdverlegte Fernwärmenetze - Verbund-Formstücke bestehend aus Stahl-Mediumrohr, Polyurethan-Wärmedämmung und Außenmantel aus Polyethylen
In dieser Europäischen Norm werden Anforderungen und Prüfmethoden für Formstücke von werksmässig gedämmten Verbundmantelrohren festgelegt, die aus einem Stahlformstück als Mediumformstück von DN 20 bis DN 600 mit Wärmedämmung aus Polyurethan-Hartschaumstoff und einer Ummantelung aus Polyethylen hoher Rohdichte bestehen. Die Anforderungen können jedoch auch für grössere Masse gelten.
Systèmes bloqués de tuyaux préisolés pour les réseaux enterrés d'eau chaude - Raccords préisolés, tubes 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'essais applicables aux raccords des systèmes préfabriqués de tubes isolés thermiquement comprenant : un raccord de service en acier de DN 20 à DN 600, une isolation en mousse rigide de polyuréthane, un tube de protection en polyéthylène de haute densité. Les prescriptions de qualité pouvant cependant s'appliquer à des dimensions supérieures.
