Flanges and their joints - Circular flanges for pipes, valves, fittings and accessories, PN designated - Part 4: Aluminium alloy flanges

This standard specifies requirements for PN designated circular flanges for pipes, valves, fittings and accessories made from aluminium alloy in the range of DN 15 to DN 600 and PN10 to PN 63 (see Table 1).
This standard specifies the types of flanges and their facings, dimensions and tolerances, bolt sizes, surface finish of jointing faces, marking and materials together with associated pressure/temperature (p/T) ratings.
The flanges are intended to be used for piping as well as for pressure vessels.

Flansche und ihre Verbindungen - Runde Flansche für Rohre, Armaturen, Formstücke und Zubehörteile, nach PN bezeichnet - Teil 4: Flansche aus Aluminiumlegierungen

Diese Norm legt Anforderungen an PN-bezeichnete kreisförmige Flansche für Rohre, Armaturen, Formstücke und Zubehörteile fest. Die Flansche werden hergestellt aus Aluminiumlegierung im Bereich DN 15 bis DN 600 und PN 10 bis PN 63 (siehe Tabelle 1).
Diese Norm enthält Festlegungen über die Typen der Flansche und ihre Dichtflächen, die Abmessungen und Toleranzen, die Schraubengrößen, die Oberflächengüte der Dichtflächen, die Kennzeichnung und Werkstoffe zusammen mit zugehörigen Druck/Temperatur-Zuordnungen (p/T ratings).
Die Flansche sind vorgesehen für den Einsatz sowohl bei Rohrleitungen als auch bei Druckbehältern.

Brides et leurs assemblages - Brides circulaires pour tubes, appareils de robinetterie, raccords et accessoires, désignées PN - Partie 4: Brides en alliages d'aluminium

La présente Norme européenne spécifie les exigences applicables aux brides circulaires désignées PN pour tubes, appareils de robinetterie, raccords et accessoires en alliages d'aluminium dans les gammes de DN 15 à DN 600 et pour PN 10 à PN 63 (voir Tableau 1).
La présente Norme européenne spécifie les types de brides et leurs portées de joints, les dimensions et tolérances, les dimensions de boulonnerie, les états de surface des portées de joints, le marquage et les matériaux ainsi que les relations pression/température (p/T) associées.
Les brides sont prévues pour être utilisée sur les réseaux de tuyauteries ainsi que sur les appareils à pression.
