(Main)Unfired pressure vessels - Part 6: Requirements for the design and fabrication of pressure vessels and pressure parts constructed from spheroidal graphite cast iron
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 Tables 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 bar 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.
Neogrevane tlačne posode - 6. del: Zahteve za konstruiranje in proizvodnjo tlačnih posod in tlačnih delov posode iz nodularne litine
Standard EN 13445-6 določa zahteve za konstruiranje, materiale, proizvodnjo in preskušanje tlačnih posod in tlačnih delov posod, namenjenih uporabi z najvišjim dovoljenim tlakom, ki je enak ali manjši od 100 barov, ter z debelinami stene lupine, ki ne presegajo 60 mm, ki so izdelani iz feritnih ali avstenitnih nodularnih litin. Omejitev debeline lupine se ne uporablja za debelino prirobnic, armatur, glav itd. Dovoljeni razredi ne zajemajo razredov lamelarnih železovih litin za feritne in avstenitne razrede, ki so izrecno izključeni iz tega evropskega standarda zaradi majhnega podaljšanja ter obnašanja krhkega materiala, ki zahteva uporabo drugačnih varnostnih dejavnikov in drugačnega pristopa.
