Title (EN) CONTAINMENT SEAL
(FR) JOINT DE CONFINEMENT
Abstract:
(EN) A containment seal seals a cable or tube to an opening accessing a containment vessel. The containment seal includes a lower body that attaches over the opening into the containment vessel. The cable or tube is inserted through a hole that extends axially through an upper body of the containment seal. Compression fittings are attached to the top and bottom ends of the upper body sealing the cable inside of the upper body. The cable sealed inside of the upper body in inserted through the lower body and into the opening accessing the containment vessel and a lower portion of the upper body is seated into the opening formed in the lower body. A retaining device compresses the upper body down against the lower body forming a seal between the upper body and lower body.
(FR) La présente invention concerne un joint de confinement scellant un câble ou un tube vers une ouverture accédant à un récipient de confinement. Le joint de confinement comprend un corps inférieur qui se fixe sur l'ouverture dans le récipient de confinement. Le câble ou le tube est inséré à travers un trou qui s'étend axialement à travers un corps supérieur du joint de confinement. Des raccords de compression sont fixés aux extrémités supérieure et inférieure du corps supérieur scellant le câble à l'intérieur du corps supérieur. Le câble scellé à l'intérieur du corps supérieur est inséré à travers le corps inférieur et dans l'ouverture accédant au récipient de confinement et une partie inférieure du corps supérieur est logée dans l'ouverture formée dans le corps inférieur. Un dispositif de retenue comprime le corps supérieur vers le bas contre le corps inférieur formant un joint d'étanchéité entre le corps supérieur et le corps inférieur.
