Title (EN) SAFE RING
(FR) ANNEAU DE SECURITE
Abstract:
(EN) A spray shield for a pipe flange joint for preventing spraying of fluid, flowing through the pipe flange joint, in case of gasket failure, comprising a band (2), which covers the gap (5) which is present between two flanges (7) in the pipe flange joint and a gasket (6) provided in between the flanges (7) and at least a portion of each flange (7) that adjoin the gap (5). A porous material (3), is loosely or fixedly arranged on the side of the band that faces the flanges (7), at least of a width covering the gap (5), to slow down and spread out fluid which sprays outwards in case of gasket failure. The material (3) has a capacity of partly take up fluid. Also the fluid taken up by the material (3) slows down the spraying fluid. The spraying fluid trickles from the porous material (3) outwards between the flanges (7) and the band (2).
(FR) L'invention concerne une protection de pulvérisation pour un joint de bride de canalisation qui empêche la pulvérisation du fluide s'écoulant à travers le joint de bride de canalisation en cas de défaillance d'un joint d'étanchéité. La protection de pulvérisation selon l'invention comprend une bande (2) couvrant l'espace (5) existant entre deux brides (7) dans le joint de bride de canalisation et un joint d'étanchéité (6) placé entre les brides (7) et au moins une partie de chaque bride (7) contiguë à l'espace (5). Un matériau poreux (3) est disposé, de manière lâche ou fixe, sur le côté de la bande qui fait face aux brides (7) ; il a au moins une largeur couvrant l'espace (5) et sert à ralentir ou à étaler le fluide qui jaillit en cas de défaillance du joint d'étanchéité. Le matériau utilisé (3) a la capacité d'absorber partiellement le fluide. D'autre part, le fluide absorbé par le matériau (3) ralentit le fluide qui jaillit. Le fluide qui jaillit s'écoule goutte à goutte du matériau poreux (3) vers l'extérieur entre les brides (7) et la bande (2).
