CheckFire Intumescent Pipe Collars consist of a powder coated steel sleeve containing a flexible graphite-based intumescent liner manufactured to suit the pipework to be firestopped. Integral toggles are opened up and the collar is simply fitted around the plastic pipe. The toggles are closed and the collar pushed flush to the surface of the wall or underside of the floor. The collar is then securely fastened to the structure by means of fire resistant fixings threaded through fixing tabs. Any gaps of up to 25mm wide around the pipework should be filled with Acoustic Intumescent Sealant. For gaps greater than 25mm wide firestop mortar/compound can be used._x000D_
Under fire conditions the intumescent material swells, filling the void left by the burnt out plastic pipe.
