PT-Diagram

PT-Diagramm-2015-GB Operating temperatures < -30°C and > 220 °C have to be checked and approved by AZ according to the operating conditions. Besides the P/T value of the sleeve the limitations of the valve bodies also have to be considered. Please refer to the EN 12516-1 resp. ASME B16.34 in order to choose a proper pressure rating (PN/class). The shown values refer to austenitic stainless steel 1.4408 (A351 Gr. CF8M). 1) For operating temperatures below -10°C low temperature / austenitic steels are required. 2) Sleeve: There are different sleeve materials / compounds available. Bei der Auswahl des Dichtbuchsen-Materials sind auch die Einsatzgrenzen gemäß EN12516-1 bzw. ASME B16.34 für die jeweiligen Druckstufen zu beachten (PN/class). Die eingezeichneten Werte beziehen sich auf austenitischen Edelstahlguß 1.4408. 1) Für den Einsatz unter -10°C Betriebstemperatur sind tieftemperatur- bzw. austenitische Stähle erforderlich. 2) Buchse: Es stehen unterschiedliche Dichtbuchsen-Materialien zur Verfügung.
