Abstract
(DE)
Vorrichtung zur dichtenden Verbindung zweier Rohrelemente Die Erfindung betrifft eine Vorrichtung zur dichtenden Verbindung zweier Rohrelemente (10, 20), bei der eine Stirnfläche eines ersten Rohrelementes dichtend mit einer Stirnfläche eines zweiten Rohrelementes verbunden ist. Jedes Rohrelement weist einen Kragen (12, 22) in radialer Richtung nach außen auf. Ein Verbindungselement (32, 30) überdeckt in axialer Richtung beide Kragen und bewirkt durch mittelbaren oder unmittelbaren Eingriff an den beiden Kragen eine axiale Verspannung der Rohrelemente. Mindestens ein erstes Ausgleichselement (14) ist in axialer Richtung zwischen dem Kragen des ersten Rohrelementes und dem Verbindungselement angeordnet. Der Längenausdehnungskoeffizient des Verbindungselementes liegt zwischen den Längenausdehnungskoeffizienten mindestens eines Kragens und des Ausgleichselementes.
(EN)
The invention relates to a device for the sealed connection of two tubular elements (10, 20), wherein an end face of a first tubular element is connected in a sealed manner to an end face of a second tubular element. Each tubular element has a collar (12, 22) extending radially outwards. A connecting element (32, 30) covers both collars in the axial direction and axially prestresses the tubular elements by directly or indirectly engaging with the two collars. At least one first compensating element (14) is positioned axially between the collar of the first tubular element and the connecting element. The coefficient of linear expansion of the connecting element is between the coefficient of linear expansion of at least one collar and of the compensating element.
(FR)
L'invention concerne un dispositif permettant de relier de manière étanche deux éléments tubulaires (10, 20), dans lequel une face frontale d'un premier élément tubulaire est reliée de manière étanche à une face frontale d'un deuxième élément tubulaire. Chaque élément tubulaire comporte un collet (12, 22) dans la direction radiale vers le haut. Un élément de liaison (32, 30) recouvre dans une direction axiale les deux collets et entraîne, par une prise indirecte ou directe sur les deux collets, un assemblage par serrage axial des éléments tubulaires. Au moins un premier élément de compensation (14) est disposé dans une direction axiale entre le collet du premier élément tubulaire et l'élément de liaison. Le coefficient de dilatation longitudinale de l'élément de liaison se situe entre les coefficients de dilatation longitudinale d'au moins un collet et de l'élément de compensation.
