Novapipe S is an intumescent pipe collar with the high performance intumescent sealing material, Novaflex, bonded to the inside of a stainless steel sleeve.
When exposed to high temperatures derived from flames or intensive heat radiation from fire the intumescent material expands many times its own volume to fill the void left by softening plastic pipe. Novapipe S is mainly used for fire sealing where plastic pipes are penetrating through fire compartment walls or floors.
Novapipe S is also suitable for fire sealing of minor plastic pipes made up into bundles.
Novapipe S is available in standard sizes to suit plastic pipes with diameter 50-200 mm.
