Description
Intumescent fire collars are designed to maintain the fire resistance of compartment walls and floors where they are penetrated by ABS sampling pipes.
The pipe collar is manufactured from a high-performance material bonded to the inside of a steel sleeve, which, on exposure to heat from a fire, will rapidly expand inwards to squeeze the collapsing plastic pipe until the aperture is completely sealed. This creates compartmentalization, which prevents the fire from spreading from one fire compartment to the next. Pipe collars are tested in accordance with the performance requirements of BS476: Part 20 1987.
- Surface mount, flush or semi-flush mount
- Prevent the spread of fire, smoke and hot gases through a building by containing it in the compartment of origin
- Maintain the integrity of escape routes from a building
- Reduce loss or damage to property from the effect of fire and smoke
- Maintain pressure differential between compartments and ventilation channels
