Abstract

Méthode de réparation d’une enveloppe, notamment d’un pressuriseur L’invention concerne une méthode de réparation d’une enveloppe apte à contenir un fluide sous pression, l’enveloppe comprenant une paroi (12) définissant une surface intérieure (14) et une surface extérieure (16) et délimitant au moins un orifice traversant (18), l’enveloppe comprenant une manchette initiale pour pénétrer l’enveloppe par l’orifice traversant (18). La méthode comprend les étapes suivantes : - retrait de la manchette initiale, - installation d’une nouvelle manchette (30) s’étendant entre une extrémité proximale (32) s’étendant dans l’orifice traversant (18) et une extrémité distale (34) s’étendant à l’extérieur de l’enveloppe, - réalisation d’une soudure (36) s’étendant dans l’orifice traversant (18) entre l’extrémité proximale (32) et la surface intérieure (14), la nouvelle manchette (30) et la soudure (36) formant ensemble un revêtement d’une surface transverse finale (28) de la paroi (12) délimitant l’orifice traversant (18).
