Flanges and their joints - Bolting - Part 4: Selection of bolting for equipment subject to the Pressure Equipment Directive 97/23/EC
This European Standard is applicable to the selection of bolting for equipment subject to the Pressure Equipment Directive 97/23/EC. It specifies standards and additional requirements for dimensions, materials and technical conditions of delivery for bolting. The bolting selection covered by this European Standard is regarded to be used for combination with flanges according to the series EN 1092 (PN designated flanges) and the series EN 1759 (Class designated flanges). The selection is based on commonly used materials, bolts and nuts. It covers temperature ranges of the general service of standard flanges (based on PN or Class).
Flansche und ihre Verbindungen - Schrauben und Muttern - Teil 4: Auswahl von Schrauben und Muttern zur Anwendung im Gültigkeitsbereich der Druckgeräterichtlinie 97/23/EG
Diese Europäische Norm gilt für die Auswahl von Schrauben und Muttern zur Anwendung im Gültigkeits¬bereich der Druckgeräte¬richtlinie 97/23/EG.
Sie legt Normen und zusätzliche Anforderungen an Maße, Werkstoffe und technische Lieferbedingungen für Schrauben und Muttern fest.
Schrauben und Muttern nach dieser Norm werden für den Gebrauch in Kombination mit Flanschen ausgewählt, die der Normenreihe EN 1092 (nach PN bezeichnete Flansche) sowie der Normenreihe EN 1759 (nach Class bezeichnete Flansche) entsprechen. Die Auswahl beruht auf allgemein gebräuchlichen Werkstoffen, Schrauben und Muttern. Sie umfasst Temperatur¬bereiche für den allgemeinen Betrieb von Standardflanschen auf der Grundlage von PN und Class. Bei der Auswahl von Schrauben und Muttern nach dieser Europäischen Norm sind weitere Parameter wie Art des Fluids, Korrosionsgefährdungen und Relaxation bei erhöhten Temperaturen zu berücksichtigen.
Zweck dieser Norm ist die Bereitstellung einer Auswahl der gebräuchlichsten Arten und Werkstoff¬kombinationen von Schrauben und Muttern als Hilfe für die einfache Auswahl der geeigneten Schrauben und Muttern für Druckgeräte.
Es ist nicht vorgesehen, sämtliche möglichen Anwendungen festzulegen, sondern eine Leitlinie für die gebräuchlichsten Anwendungen bereitzustellen. Dementsprechend werden z. B. Werkstoffe innerhalb des Kriechbereiches in dieser Norm nicht behandelt, aber einige der aufgeführten Werkstoffe von Schrauben und Muttern sind für die Anwendung in diesem Temperaturbereich geeignet.
ANMERKUNG Spezielle Betriebs- und Umgebungsbedingungen können das Aufbringen von Beschichtungen erfordern. Die Entscheidung darüber obliegt dem Anwender. In Abhängigkeit von der verwendeten Beschichtung kann eine Verifizierung des in Tabelle 3 angegebenen Temperaturbereiches erforderlich sein.
Brides et leurs assemblages - Boulonnerie - Partie 4: Sélection de la boulonnerie pour équipements relevant de la Directive Equipements sous pression 97/23/CE
La présente Norme européenne est applicable à la sélection de la boulonnerie destinée aux équipements relevant de la Directive Équipements sous pression 97/23/CE.
Elle spécifie les normes et les exigences supplémentaires relatives aux dimensions, matériaux et conditions techniques de livraison applicables à la boulonnerie.
La boulonnerie visée par la présente norme est sélectionnée en fonction de son utilisation associée à des brides conformes aux séries EN 1092 (brides désignées PN) et EN 1759 (brides désignées Class). La sélection s’appuie sur des matériaux, boulons et écrous couramment utilisés. Elle couvre les plages de température, en fonction du PN ou de la Class, des brides normalisées d’usage général. Lors de la sélection de la boulonnerie conforme à la présente Norme européenne, d’autres paramètres tels que les fluides, les dangers dus à la corrosion et la relaxation à températures élevées doivent être pris en compte. L’objectif de la présente norme est de fournir une sélection des types de boulonnerie et des combinaisons de matériaux de boulonnerie les plus couramment utilisés afin de mettre à disposition un outil permettant de faciliter le choix d’une boulonnerie appropriée aux équipements sous pression.
Cette norme n’a pas l’intention de spécifier toutes les applications possibles mais plutôt de fournir des lignes directrices sur les applications les plus courantes. Conformément à cette précision, certains matériaux de la plage de fluage par exemple ne sont pas traités par la présente norme mais certains matériaux de boulonnerie répertoriés conviennent pour une utilisation dans cette plage de température.
NOTE 1 Des applications spéciales et des conditions à température ambiante peuvent exiger l’application de revêtements. Cette décision est laissée à l’initiative de l’utilisateur. En fonction du revêtement utilisé, une vérification des plages de température données dans le Tableau 3 peut s’avérer nécessaire.

1 Scope This European Standard is applicable to the selection of bolting for equipment subject to the Pressure Equipment Directive 97/23/EC. It specifies standards and additional requirements for dimensions, materials and technical conditions of delivery for bolting. The bolting selection covered by this European Standard is regarded to be used for combination with flanges according to the series EN 1092 (PN designated flanges) and the series EN 1759 (Class designated flanges). The selection is based on commonly used materials, bolts and nuts. It covers temperature ranges of the general service of standard flanges (based on PN or Class). NOTE 1 The bolting selection given may be used in combination with non-standard flanges too provided that the range of application of the equipment for which the bolting is intended to be used is covered. It is the purchaser's option to decide on this. When selecting bolting according to this European Standard it is essential to take into account other parameters such as type of fluids, corrosion hazards and relaxation at elevated temperatures. The purpose of this European Standard is to provide a selection of most commonly used bolting types and bolting material combinations as well a tool for easy selection of suitable bolting for equipment. It is not the intention to specify all possible applications but to give guidance on the most commonly applications. According to this, e.g. application limits for material in the creep range are not explicitly covered in this European Standard but some bolting materials listed (see Table 3, footnote h) are suitable to be used in this temperature range. Wherever the starting material standard provides mechanical properties for this temperature range respective reference is made in Table 3. NOTE 2 Special services and ambient conditions may require the application of coatings. It is the purchaser's option to decide on this. Depending on the coating used, a verification of the temperature ranges given in Table 3 may be required. 2 Normative references The following referenced documents are indispensable for the application of this document.

Wherever material combinations are listed upper suitable temperature is chosen to comply with the lowest permissible of one of them. For some materials mechanical properties at higher temperature exist, e.g. creep values to be taken into consideration as appropriate.
