Intumescent Pipe Collars
by Firewise Supplies
PFC Corofil Intumescent Firestop Collars consist of a powder coated Steel sleeve containing a flexible graphite based intumescent liner manufactured to suit the diameter of 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 is 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 through the fixing tabs.Annular gaps around the pipe of up to 10mm wide must be filled with PFC Corofil Acoustic Intumescent Sealant. For annular gaps greater than 10mm, PFC Corofil Firestop Compound must be used. Under fire conditions, the intumescent material swells and fills the void left by the burnt out plastic.
