Welded steel tubes for pressure purposes - Technical delivery conditions - Part 2: Electric welded non-alloy and alloy steel tubes with specified elevated temperature properties

This Part of EN 10217 specifies the technical delivery conditions in two test categories of electric welded tubes of circular cross section, with specified elevated temperature properties, made of non-alloy and alloy steel.

Geschweißte Stahlrohre für Druckbeanspruchungen - Technische Lieferbedingungen - Teil 2: Elektrisch geschweißte Rohre aus unlegierten und legierten Stählen mit festgelegten Eigenschaften bei erhöhten Temperaturen

Dieses Dokument legt die technischen Lieferbedingungen für elektrisch geschweißte Rohre mit kreisförmigem Querschnitt aus unlegiertem und legiertem Stahl mit festgelegten Eigenschaften bei erhöhten Temperaturen für zwei Prüfkategorien fest.
ANMERKUNG 1 Die Rohrgüten sind vorgesehen zur Unterstützung der grundlegenden Anforderungen der EU-Richtlinie 2014/68/EU bezüglich Druckgeräten mit festgelegten Eigenschaften bei erhöhten Temperaturen und sie decken alle festgelegten Kategorien nach Artikel 13 der Richtlinie ab.
ANMERKUNG 2 Nach Veröffentlichung dieser Norm im EU-Amtsblatt (ABl.) ist die Annahme ihrer Konformität mit den grundlegenden Sicherheitsanforderungen (ESR) der Richtlinie 2014/68/EU auf die technischen Daten von Werkstoffen in dieser Norm beschränkt, und es darf nicht angenommen werden, dass damit die Eignung des Werkstoffs für ein bestimmtes Ausrüstungsteil festgestellt ist. Folglich müssen die in dieser Werkstoffnorm angegebenen technischen Parameter im Hinblick auf die konstruktiven Anforderungen dieses bestimmten Ausrüstungsteils ermittelt werden, um damit zu verifizieren, dass den ESR der Druckgeräterichtlinie entsprochen wird. Dies muss durch den Ausleger oder den Hersteller der Druckgeräte geschehen, der auch den nachfolgenden Herstellungsprozess berücksichtigen muss, der die Eigenschaften des Grundmaterials verändern kann.

Tubes soudés en acier pour service sous pression - Conditions techniques de livraison - Partie 2: Tubes soudes électriquement en acier non allié et allié avec caractéristiques spécifiées à température élevée

La présente Norme européenne spécifie les conditions techniques de livraison de deux catégories d’essai de tubes soudés électriquement à section circulaire, avec caractéristiques spécifiées à température élevée, fabriqués en aciers non alliés et alliés.
NOTE 1   Ces nuances sont destinées à remplir les exigences essentielles de la directive 2014/68/UE de l'UE sur les équipements sous pression avec caractéristiques spécifiées à température élevée, concernant toutes les catégories pertinentes comme exposé dans l’article 13 de cette directive.
NOTE 2   Dès lors que la présente Norme européenne est publiée dans le Journal Officiel de l’Union européenne (JOUE) en lien avec la Directive 2014/68/UE, la présomption de conformité avec les exigences essentielles de sécurité de la Directive 2014/68/UE se limite aux données techniques des matériaux spécifiées dans la présente Norme européenne et ne suppose pas l’adéquation des matériaux avec un appareil en particulier. Par conséquent, il doit être procédé à l’évaluation des données techniques spécifiées dans la présente norme de matériaux par rapport aux exigences concernant la conception de cet équipement spécifique, afin de vérifier que les exigences essentielles de sécurité de la Directive 2014/68/UE soient satisfaites en tenant en compte des opérations ultérieures de production qui peuvent impacter le matériau de base.

SIST EN 10217-2:2019
EN 10217-2:2019 (E)
1 Scope
This document specifies the technical delivery conditions for two test categories of electric welded tubes of
circular cross section, with specified elevated temperature properties, made from non-alloy quality steel or
alloy special steel.
NOTE 1 These tube grades are intended to support the essential requirements of EU Directive 2014/68/EU in
respect of pressure equipment with specified elevated temperature properties, covered under all relevant Categories as
set out in Article 13 of that Directive.
NOTE 2 Once this standard is published in the Official Journal of the European Union (OJEU), presumption of
conformity to the Essential Safety Requirements (ESR) of Directive 2014/68/EU is limited to the technical data for the
materials in this standard and does not presume adequacy of the material for a specific item of pressure equipment.
Consequently, the assessment of the technical data stated in this material standard against the design requirements of a
specific item of equipment to verify that the ESRs of the Pressure Equipment Directive are satisfied, needs to be done by
the designer or manufacturer of the pressure equipment, taking also into account any subsequent processing
procedures which may affect properties of the base materials.
