Flanges and their joints - Design rules for gasketed circular flange connections - Part 1 : calculation method

Le présent document décrit une méthode de calcul des assemblages à brides boulonnées circulaires avec joint. Cette méthode de calcul vérifie le respect de critères à la fois d'étanchéité et de résistance. Il prend en compte le comportement de l'ensemble que forme le système brides - boulons - joint. Les normes NF EN 1591-2 et NF EN 13555 définissent respectivement des valeurs qui peuvent être utilisées pour les caractéristiques de joints intervenant dans cette méthode de calcul et des modes opératoires d'essais applicables. Il permet de répondre aux exigences essentielles de la Directive Équipements Sous Pression (DESP) 97/23/CE .

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
