A pressure-relieving safety assembly, comprising a sleeve (108) and collar (104), protects against human injury and loss of Inc by blocking flow of fluid from a ruptured high pressure conduit (114) and provides pressure relief for escaping flu-id. This pressure-relieving assembly includes a sleeve (108) that encircles the high-pressure line and is secured to, at one or both ends of the line, a coupling. The sleeve is secured to the coupling (s) by a collar (104) having raised portions that provides a path for fluid that has escaped from the conduit at a burst or pin-hole failure location, to flow towards the ends of the conduit, indicating to the user that a conduit failure has occurred. The sleeve lowers the fluid velocity while the path provided by the collar prevents the fluid pressure from building up behind the sleeve.

L'invention porte sur un ensemble de sécurité contre la surpression, comprenant un manchon (108) et un collier (104), lequel ensemble de sécurité protège les êtres humains vis-à-vis d'une blessure et de la mort par blocage de l'écoulement de fluide d'un conduit haute pression rompu (114) et assure une détente de pression pour du fluide s'échappant. Cet ensemble de sécurité contre la surpression comprend un manchon (108) qui encercle la ligne haute pression et est fixé à, au niveau d'une extrémité ou des deux extrémités de la ligne, un raccord. Le manchon est fixé au ou aux raccords par un collier (104) ayant des parties surélevées qui fournissent un trajet pour que le fluide, qui s'est échappé du conduit en un emplacement de défaillance due à un éclatement ou un trou d'épingle, s'écoule vers les extrémités du conduit, indiquant à l'utilisateur qu'une défaillance de conduit s'est produite. Le manchon abaisse la vitesse du fluide alors que le trajet fourni par le collier empêche la pression de fluide de s'accumuler derrière le manchon.
