A fire collar (10) is supported around a plastics material pipe (30) extending through a bore (32) in a wall (44). The fire collar (10) comprises a cylindrical metal collar (12) carrying a layer of intumescent material (36) on its inner circumferential surface. A sleeve (22) of fire resistant material is attached to the metal collar (10) and extends within the collar and around the pipe (30). In the event of a fire the pipe (30) melts. The intumescent material (36) is constrained to expand radially inwardly and as it does so it pushes the fabric sleeve (22) radially inwardly. The sleeve (22) and the expanded intumescent material (36) together form a physical barrier across the fire collar (10) which blocks the bore (32).
Un collier pare-feu (10) est fixé autour d'un tuyau en matière plastique (30) traversant un mur (44) par un orifice de passage (32). Le collier pare-feu (10) comprend un collier métallique cylindrique (12) dont la surface intérieure est revêtue sur sa circonférence d'une couche de matière intumescente (36). Un manchon (22) en matière résistante au feu tapisse ensuite l'intérieur du collier en métal (10) et enveloppe le tuyau (30). En cas d'incendie, le tuyau (30) fond. La matière intumescente (36) est alors contrainte à gonfler vers l'intérieur de manière radiale en poussant le manchon (22) dans la même direction. Ensemble, le manchon (22) et la matière intumescente gonflée forment un obstacle physique qui obstrue le collier pare-feu (10) et bloque l'orifice de passage (32).
