Seamless steel tubes for pressure purposes - Technical delivery conditions - Part 5: Stainless steel tubes

This document specifies the technical delivery conditions in two test categories for seamless tubes of a circular cross section made of austenitic (including creep resisting steel) and austenitic-ferritic stainless steel which are intended for pressure and corrosion resisting purposes at room temperature, at low temperatures or at elevated temperatures.
NOTE   Once this document is published in the Official Journal of the European Union (OJEU) under Directive 2014/68/EC, presumption of conformity to the Essential Safety Requirements (ESR) of Directive 2014/68/EC is limited to technical data of materials in this document and does not presume adequacy of the material to a specific item of equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of this specific item of equipment to verify that the ESRs of the Pressure Equipment Directive are satisfied will be done by the designer or manufacturer of the pressure equipment, taking also into account the subsequent manufacturing processes which could affect properties of the base materials.

Nahtlose Stahlrohre für Druckbeanspruchungen - Technische Lieferbedingungen - Teil 5: Rohre aus nichtrostenden Stählen

Dieses Dokument legt die technischen Lieferbedingungen mit zwei Testkategorien für nahtlose Rohre mit kreis¬för¬mi¬gem Querschnitt aus austenitischen (einschließlich warmfesten) Stählen und aus austenitisch-ferritischen nichtrostenden Stählen fest, die für Druckbeanspruchungen und für korrosive Medien bei Raumtem¬pe¬ra¬tur, bei tiefen Temperaturen und bei erhöhten Temperaturen bestimmt sind.
ANMERKUNG   Nach Veröffentlichung dieses Dokumentes im EU Amtsblatt (OJEU) unter der Richtlinie 2014/68/EU ist die Annahme ihrer Konformität mit den grundlegenden Anforderungen (ESR, en: Essential Safety Requirements) der Richtlinie 2014/68/EU auf die technischen Daten von Werkstoffen in diesem Dokument 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 Ausrüstungs¬teils 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 sans soudure pour service sous pression - Conditions techniques de livraison - Partie 5 : Tubes en aciers inoxydables

Le présent document spécifie les conditions techniques de livraison, pour deux catégories d’essai, pour les tubes sans soudure à section circulaire en acier inoxydable austénitique (y compris acier résistant au fluage) et austéno-ferritique, qui sont destinés à être utilisés en service sous pression et pour des applications avec résistance à la corrosion, à température ambiante, à basse température ou à température élevée.
NOTE   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 Équipement Sous Pression soient satisfaites, évaluation qui sera effectuée par le concepteur ou le fabricant d’équipement sous pression, en tenant aussi compte des procédés ultérieurs de fabrication qui peuvent affecter les propriétés des matériaux de base.

1 Scope

This document specifies the technical delivery conditions in two test categories for seamless tubes of a

circular cross section made of austenitic (including creep resisting steel) and austenitic-ferritic stainless

steel which are intended for pressure and corrosion resisting purposes at room temperature, at low

temperatures or at elevated temperatures.

NOTE Once this document is published in the Official Journal of the European Union (OJEU) under Directive

2014/68/EC, presumption of conformity to the Essential Safety Requirements (ESR) of Directive 2014/68/EC is

limited to technical data of materials in this document and does not presume adequacy of the material to a specific

item of equipment. Consequently, the assessment of the technical data stated in this material standard against the

design requirements of this specific item of equipment to verify that the ESRs of the Pressure Equipment Directive

are satisfied will be done by the designer or manufacturer of the pressure equipment, taking also into account the

subsequent manufacturing processes which could affect properties of the base materials.

European foreword

This document (prEN 10216-5:2018) has been prepared by Technical Committee ECISS/TC 110 “Steel

tubes and iron and steel fittings”, the secretariat of which is held by UNI.
This document is currently submitted to the CEN Enquiry.

This document has been prepared under a mandate given to CEN by the European Commission and the

European Free Trade Association, and supports essential requirements of EU Directive(s).

For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this

document.
This document will supersede EN 10216-5:2013.

The following changes have been made in comparison to the previous edition EN 10216-5:2013:

a) the normative references have been updated;
b) in Table 6 and Table 7, the footnote "a" has been completed;
c) in subclause 8.8, the dated reference of the standards has been deleted;

d) in Table 15, the frequency of testing in test category 2 for tensile test at room temperature has been

modified;
e) the impact testing (subclause 11.4.1) has been modified;
f) the standard has been editorially revised.

This European Standard consists of the following parts, under the general title Seamless steel tubes for

pressure purposes – Technical delivery conditions:
— Part 1: Non-alloy steel tubes with specified room temperature properties;

— Part 2: Non-alloy and alloy steel tubes with specified elevated temperature properties;

— Part 3: Alloy fine grain steel tubes;

— Part 4: Non-alloy and alloy steel tubes with specified low temperature properties;

— Part 5: Stainless steel tubes (the present document).
Another European Standard series covering tubes for pressure purposes is:

— EN 10217, Welded steel tubes for pressure purposes – Technical delivery conditions

1 Scope

This document specifies the technical delivery conditions in two test categories for seamless tubes of

circular cross section made of austenitic (including creep resisting steel) and austenitic-ferritic stainless

steel which are intended for pressure and corrosion resisting purposes at room temperature, at low

temperatures or at elevated temperatures.

NOTE Once this standard is published in the Official Journal of the European Union (OJEU) under Directive

2014/68/EC, presumption of conformity to the Essential Safety Requirements (ESR) of Directive 2014/68/EC is

limited to technical data of materials in this standard and does not presume adequacy of the material to a specific

item of equipment. Consequently, the assessment of the technical data stated in this material standard against the

design requirements of this specific item of equipment to verify that the ESRs of the Pressure Equipment Directive

are satisfied will be done by the designer or manufacturer of the pressure equipment, taking also into account the

subsequent manufacturing processes which may affect properties of the base materials.
