Firestem Pipe Collars

Product Description

In order to obtain effective Fire Prevention it is necessary to consider the actual penetrations through fire compartment walls and floors. Synthetic pipes should be especially considered as they are a transporter of fire and smoke from one compartment to another.

The Firestem™ Pipe Collar consists of a one part system, 1.5mm thick and closed by use of a toggle clip. The shells are lined with a new generation intumescent impervious to water.

One side of the collar has 4 mounting lugs with four holes of 7mm diameter for fixing by means of metal expanding (or through) bolts 6mm diameter.

PVC and PE starts to soften at about 115°C, consequently in a short period of time an opening will develop in a fire compartment wall or floor allowing flames and smoke to breach it.

The Firestem™ Intumescent Collar counteracts this and at around 140°C the Firestem™ Flex starts to react under the influence of heat, expanding to seal off the pipe thereby stopping the spread of smoke and fire.
