Butt-welding pipe fittings - Part 4: Wrought austenitic and austenitic-ferritic (duplex) stainless steels with specific inspection requirements
1.1 This European Standard specifies the technical delivery requirements for seamless and welded butt-welding fittings (elbows, concentric and eccentric reducers, equal and reducing tees, caps) made of austenitic and austenitic-ferritic (duplex) stainless steel which are intended for pressure and corrosion resisting purposes at room temperature, at low temperature or at elevated temperatures.
It specifies:
the type of fittings;
type A (see 7.2)
type B (see 7.3)
the steel grades;
the mechanical properties;
the dimensions and tolerances;
the requirements for inspection and testing;
the inspection documents;
the marking;
the handling and packaging.
NOTE In the case of a harmonised supporting standard for materials, presumption of conformity to the Essential Requirement(s) (ESRs) is limited to technical data of materials in the standard and does not presume adequacy of the material to a specific item of equipment. Consequently the technical data stated in the material standard should be assessed against the design requirements of this specific item of equipment to verify that the ESRs of the Pressure Equipment Directive (PED) are satisfied.
1.2 Unless otherwise specified in this European Standard the general technical delivery requirements in EN 10021 apply.
Formstücke zum Einschweißen - Teil 4: Austenitische und austenitisch-ferritische (Duplex-)Stähle mit besonderen Prüfanforderungen
1.1 Diese Europäische Norm legt die technischen Lieferbedingungen für nahtlose und geschweißte Formstücke zum Einschweißen (Rohrbogen, konzentrische und exzentrische Reduzierstücke, T Stücke mit gleichem Abzweig und T Stücke mit reduziertem Abzweig, Kappen) aus nicht rostendem austenitischem und austenitisch ferritischem (Duplex )Stahl fest, die für druck und korrosionsbeständige Anwendungsfälle bei Raumtemperatur, Niedrigtemperatur oder bei erhöhten Temperaturen vorgesehen sind.
Diese Norm legt fest:
die Bauart der Formstücke;
Bauart A (siehe 7.2);
Bauart B (siehe 7.3);
die Stahlsorten;
die mechanischen Eigenschaften;
die Maße und Grenzabmaße;
die Anforderungen an die Prüfungen;
die Prüfbescheinigungen;
die Kennzeichnung;
die Versandvorbereitung und Verpackung.
ANMERKUNG Bei einer harmonisierten unterstützenden Norm für Werkstoffe ist die Konformitätsvermutung hinsichtlich der grundlegenden Sicherheitsanforderungen (ESR) auf die in der Norm angegebenen technischen Daten von Werkstoffen begrenzt und setzt nicht die Eignung des Werkstoffes auf ein bestimmtes Geräteteil voraus. Folglich sollten die in der Werkstoffnorm angegebenen technischen Daten in Bezug auf die Anforderungen für die Berechnung dieses bestimmten Geräteteils bewertet werden, um zu überprüfen, ob die grundlegenden Sicherheitsanforderungen der Druckgeräterichtlinie (PED) erfüllt sind.
1.2 Falls in dieser Europäischen Norm nichts anderes festgelegt ist, gelten die allgemeinen technischen Lieferbedingungen nach EN 10021.
Raccords à souder bout à bout - Partie 4: Aciers inoxydables austénitiques et austéno-ferritiques (duplex) avec contrôle spécifique
1.1 La présente Norme européenne spécifie les conditions techniques de livraison pour les raccords à souder bout à bout sans soudure et soudés (coudes, réductions concentriques et excentriques, tés égaux et tés réduits, fonds) en acier inoxydable austénitique et austéno-ferritique (duplex) utilisés pour des applications sous pression avec résistance à la corrosion à température ambiante, à basse température ou à des températures élevées.
Elle spécifie:
le type de raccord ;
type A (voir 7.2)
type B (voir 7.3)
les nuances d'acier ;
les caractéristiques mécaniques ;
les dimensions et tolérances ;
les prescriptions relatives aux contrôles et essais ;
les documents de contrôle ;
le marquage ;
la manutention et le conditionnement.
NOTE Dans le cas d'une norme harmonisée support de matériaux, la présomption de conformité aux exigences essentielles (ESR) est limitée aux données techniques des matériaux indiquées dans la norme et ne présume pas de l'adéquation du matériau à une partie spécifique de l'équipement. Par conséquent, il convient de vérifier les données techniques figurant dans la norme du matériau par rapport aux exigences de conception de cette partie spécifique afin de vérifier que les ESR de la Directive Equipements sous Pression (DESP) sont satisfaites.
1.2 Sauf spécification contraire dans la présente Norme européenne, les conditions techniques générales de livraison de l’EN 10021 s’appliquent.
