Title
(EN) APPARATUS AND METHOD FOR SEALING AND MONITORING A BOLTED FLANGE JOINT
(FR) APPAREIL ET PROCÉDÉ D'ÉTANCHÉITÉ ET DE SURVEILLANCE D'UN ASSEMBLAGE À BRIDES BOULONNÉES
Abstract
(EN)
Bolted flange joint sealing and monitoring apparatus, the bolted flange joint comprising two flanges abutting one another at an interface and the abutting flanges providing an inner surface and an outer surface, the apparatus including: a layer of sealant (10) applied to the interface (6) and an area of the abutting flanges surrounding the interface on at least one of the inner and outer surfaces; on at least one of the inner and outer surfaces a first layer of sheet material (13) adapted to provide an air space; a second layer of sheet material (15) overlying the first layer (13); a fluid impermeable sealant (16) overlying the second layer (15); wherein an air tight space is formed around the first layer (13), a vacuum source in fluid communication with said air tight space, vacuum monitoring means configured to monitor the status of a vacuum created in the air tight space.
(FR)
Appareil d'étanchéité et de surveillance à assemblage à brides boulonnées, l'assemblage à brides boulonnées comprenant deux brides en butée l'une contre l'autre au niveau d'une interface et les brides en butée procurant une surface interne et une surface externe, l'appareil comportant : une couche d'agent d'étanchéité (10) appliquée sur la surface (6) et une zone des brides en butée entourant l'interface sur la surface interne et/ou la surface externe; sur la surface interne et/ou la surface externe, une première couche de matériau en feuille (13) conçue pour fournir un espace d'air : une deuxième couche de matériau en feuille (15) recouvrant la première couche (13); un agent d'étanchéité (16) imperméable au fluide recouvrant la deuxième couche (15); un espace étanche à l'air étant formé autour de la première couche (13), une source de vide en communication fluidique avec cet espace étanche à l'air, un moyen de surveillance du vide étant conçu pour surveiller l'état d'un vide créé dans l'espace étanche à l'air.
