description A subsea safety system (50) for use during a well treatment operation. The subsea safety system (50) includes a tubular string having an inner flow passage (112). At least one valve assembly (116, 134) is positioned within the tubular string. The valve assembly (116, 134) is operable between open and closed positioned to selectively permit and prevent fluid flow therethrough. A frangible liner (134) is disposed within the valve assembly (116, 134). The frangible liner (134) has a close fitting but not fluid tight relationship with the valve assembly (116, 134). The frangible liner (134) is operable to protect the valve assembly (116, 134) from particle flow during the well treatment operation. In addition, the frangible liner (134) is operable to shatter responsive to closure of the valve assembly (116, 134), thereby allowing full operation of the valve assembly (116, 134). L'invention concerne un système de sécurité sous-marin (50) utilisé lors d'une opération de traitement de puits. Le système de sécurité sous-marin (50) comprend une rame tubulaire dotée d'un passage d'écoulement intérieur (112). Au moins un ensemble vanne (116, 134) est positionné à l'intérieur de la rame tubulaire. L'ensemble vanne (116, 134) peut être actionné entre une position ouverte et une position fermée pour permettre et empêcher sélectivement le fluide de le traverser. Un chemisage cassant (134) est placé dans l'ensemble vanne (116, 134). Le chemisage cassant (134) est en ajustement serré mais pas étanche aux fluides avec l'ensemble vanne (116, 134). Le chemisage cassant (134) sert à protéger l'ensemble vanne (116, 134) contre la circulation de particules lors de l'opération de traitement du puits. De plus, le chemisage cassant (134) est conçu pour se briser suite à la fermeture de l'ensemble vanne (116, 134), ce qui permet le fonctionnement complet de l'ensemble vanne (116, 134).
