Preinsulated bonded pipe systems for underground hot water networks - Pipe assembly of steel service pipes, 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 underground hot water networks, comprising a steel service pipe from DN 20 to DN 600, rigid polyurethane foam insulation and an outer casing of high density polyethylene. This standard applies only to injected (poured) insulated pipe assemblies, for continuous operation with hot water at various temperatures up to 120°C and for short term operation with a peak temperature up to 140°C.
Werksmäßig gedämmte Verbundmantelrohrsysteme für erdverlegte Fernwärmenetze - Verbund-Rohrsystem bestehend aus Stahl-Mediumrohr, Polyurethan-Wärmedämmung und Außenmantel aus Polyethylen
In dieser Norm werden Anforderungen und Prüfungen für gerade, werksmässig gedämmte Verbundmantelrohre für erdverlegte Fernwärmenetze festgelegt, die aus einem Stahlrohr als Mediumrohr von DN 20 bis DN 600 mit Wärmedämmung aus Polyurethan-Hartschaum und einem Mantelrohr aus Polyethylen hoher Rohdichte bestehen. Diese Norm gilt nur für Verbundsysteme für Dauerbetrieb mit Warmwasser bei Betriebstemperaturen bis 120°C und für kurzzeitigen Betrieb mit Spitzentemperaturen bis 140°C.
