Unfired pressure vessels - Part 6: Requirements for the design and fabrication of pressure vessels and pressure parts constructed from spheroidal graphite cast iron
This European Standard specifies requirements for the design, materials, manufacturing and testing of pressure
vessels and pressure vessel parts intended for use with a maximum allowable pressure, PS, equal or less than 100
bar and shell wall thicknesses not exceeding 60 mm, which are constructed of ferritic or austenitic spheroidal
graphite cast iron. The thickness limitation of the shell does not apply to thickness of flanges, reinforcements,
bosses etc.
The allowable grades do not include lamellar graphite cast iron grades for ferritic and austenitic grades, which are
explicitly excluded from this European Standard because of low elongation and brittle material behaviour, which
requires the use of different safety factors and a different approach.
NOTE 1 Austenitic spheroidal graphite cast iron grades are principally used for high and low temperature applications and for
their corrosion resistance properties.
NOTE 2 The allowable grades of spheroidal graphite cast iron are listed in Tables 3 and 4. Service conditions are given in
Clause 4.
Unbefeuerte Druckbehälter - Teil 6: Anforderungen an die Konstruktion und Herstellung von Druckbehältern und Druckbehälterteilen aus Gusseisen mit Kugelgraphit
Diese Europäische Norm legt Anforderungen an Konstruktion, Werkstoffe, Herstellung und Prüfung von
Druckbehältern und Druckbehälterteilen aus ferritischem oder austenitischem Gusseisen mit Kugelgraphit fest, die
für den Betrieb mit einem maximalen zulässigen Druck PS gleich oder kleiner als 100 bar und einer maximalen
Wanddicke von 60 mm vorgesehen sind. Die Grenzwerte für die Schalenwanddicke gelten nicht für die Dicke von
Flanschen, Verstärkungen, Nocken usw.
Zu den zulässigen Sorten gehören keine ferritischen und austenitischen Gusseisensorten mit Lamellengraphit, die
aufgrund ihrer nicht ausreichenden Dehnungs- und Sprödbrucheigenschaften von dieser Europäischen Norm
ausdrücklich ausgeschlossen sind, da für sie die Verwendung anderer Sicherheitsbeiwerte und ein anderer Ansatz
erforderlich sind.
ANMERKUNG 1 Austenitische Gusseisensorten mit Kugelgraphit werden hauptsächlich für Anwendungsfälle in hohen und
niedrigen Temperaturbereichen und aufgrund ihrer Korrosionsbeständigkeit eingesetzt.
ANMERKUNG 2 Die zulässigen Gusseisensorten mit Kugelgraphit sind in den Tabellen 3 und 4 aufgelistet. Die
Betriebsbedingungen sind in Abschnitt 4 angegeben.
Récipients sous pression non soumis à la flamme - Partie 6 : exigences pour la conception et la fabrication des récipients sous pression et des parties sous pression moulés en fonte à graphite sphéroïdal
La présente Norme européenne spécifie les prescriptions relatives à la conception, aux matériaux, à la fabrication
et aux essais des récipients sous pression et de leurs parties sous pression, destinés à être utilisés à une pression
maximale admissible, PS, inférieure ou égale à 100 bars et d’épaisseur de paroi de la coque ne dépassant pas
60 mm, fabriqués en fonte à graphite sphéroïdal ferritique ou austénitique. La limite d'épaisseur de la coque ne
s'applique pas à l'épaisseur des brides, renforcements, bossages, etc..
Les nuances admises n'incluent pas les nuances de fonte à graphite lamellaire qui sont explicitement exclues de la
présente Norme européenne du fait d'un faible allongement et d'un comportement de matériau fragile, nécessitant
l'application de coefficients de sécurité différents et d'une approche différente.
NOTE 1 Les nuances de fonte à graphite sphéroïdal austénitique sont utilisées principalement pour les applications à basse
température et à température élevée, ainsi que pour leurs propriétés de résistance à la corrosion.
NOTE 2 Les nuances admises de fonte à graphite sphéroïdal sont énumérées dans les Tableaux 3 et 4. Les conditions de
service sont données à l'Article 4.
