Astoflame intumescent pipe collars are manufactured from a high performance material bonded to the inside of a steel sleeve. On exposure to heat from a fire they rapidly expand inwards to squeeze the collapsing plastic pipe until the aperture is completely sealed. Pipe collars are tested in accordance with the performance requirements of BS476: Part 20: 1987. The pipe collars are light and compact, easy to install, maintenance free and find uses in multi- storey office buildings, flat level developments, hospitals, high rise residential properties, tower blocks and hotels.

These collars can be surface mounted, cast or semi-cast in situ. Suitable for use and anywhere plastic soil and waste pipes pass through fire compartment walls and floors. We suggest any gap around the pipe is sealed with a proprietary fire stopping material, such as intumescent mastic, before the fire collar is installed.
