Seamless steel tubes for pressure purposes - Technical delivery conditions - Part 5: Stainless steel tubes
EN 10216-5 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.
Nahtlose Stahlrohre für Druckbeanspruchungen - Technische Lieferbedingungen - Teil 5: Rohre aus nichtrostenden Stählen
Diese Europäische Norm 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 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 dieser Norm im EU Amtsblatt (OJEU) unter der Richtlinie 97/23/EG ist die Annahme ihrer Konformität mit den grundlegenden Anforderungen (ESR) der Richtlinie 97/23/EG auf die technischen Daten von Werkstoffen in dieser Europäischen 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 Ausrüstungs¬teils ermittelt werden, um damit zu verifizieren, dass den ESR der Richtlinie 97/23/EG 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.

La présent Norme européenne 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 97/23/CE, la présomption de conformité avec les exigences essentielles de sécurité de la Directive 97/23/CE 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 97/23/CE soient satisfaites.

EN 10216-5:2013 (E) 5 1 Scope This European Standard 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 97/23/EC, presumption of conformity to the Essential Safety Requirements (ESR) of Directive 97/23/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, needs to 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. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

The operating authorization issued by the employer shall be in accordance with a written procedure. NDT operations shall be authorized by a level 3 NDT individual approved by the employer. NOTE The definition of level 1, 2 and 3 can be found in appropriate standards, e.g. EN ISO 9712 and ISO 11484. 7.2.2 The tubes shall be manufactured by a seamless process, and may be hot finished or cold finished. The terms “ hot finished “ and “ cold finished “ apply to the condition of the tube before it is heat treated in accordance with 7.2.3. The process of manufacture is left to the discretion of the manufacturer, but see option 2. 7.2.3 The tubes shall be supplied in the solution annealed condition over their full length in either: reference heat treatment conditions; solution annealed conditions obtained directly by extrusion and subsequent cooling provided the mechanical properties, corrosion resistance and other properties are in accordance with this part of EN 10216. All specified mechanical properties shall be met even after a subsequent reference heat treatment (solution annealing). Solution treatment shall consist of heating the tubes uniformly to a temperature within the range given for the steel grade concerned in Tables 6, 7 and 8 and cooling rapidly. 7.2.4 The types of delivery condition of the tubes are given in Table 1.

In addition, the general technical delivery requirements specified in EN 10021 shall apply. 8.2 Chemical composition 8.2.1 Cast analysis The cast analysis reported by the steel manufacturer shall apply and conform to the requirements of Table 2 or Table 3 for austenitic steels and of Table 4 for austenitic-ferritic steels. Option 3: (see Table 2). When welding tubes produced in accordance with this part of EN 10216, account should be taken to the fact that the behaviour of the steel during and after welding is dependent not only on the steel, but also on the applied heat treatment and the conditions of preparing for and carrying out the welding. 8.2.2 Product analysis Option 4: Product analysis for the tubes shall be supplied. Table 5 specifies the permissible deviation of the product analysis from the specified limits on cast analysis given in Tables 2, 3 and 4. SIST EN 10216-5:2014
