Where are fire collars required?
A fire collar is a type of fire resistant fitting that maintains the integrity and fire insulating rating of a building element which has been penetrated by building services. This might be required, for example, when walls or floors are penetrated by cables, ducts, pipework, and so on.
How do intumescent pipe collars work?
Both intumescent pipe collars (or fire collars) and intumescent pipe wraps work on the same principle; in the event of a fire, when exposed to heat, the intumescent material expands crushing the plastic pipe as it softens and plugs the hole.
What is the purpose of an intumescent collar?
Use fire collars on pipes passing through walls and fire barriers to help prevent the spread of smoke and fire. The pipe collars fit to surface openings, expanding in fire to fill the space and stop smoke and flames penetrating.
On which side of a wall should the intumescent pipe collar be fitted?
Tighten the nuts onto the bolts. 6) NOTE Where there is a fire risk on both sides of the wall, or the direction of fire risk has not been determined, then an Astro Collar should be fitted to both sides of the wall.
Do metal pipes need fire collars?
Metal Pipes – Standard fire collars are usually not suitable for fire sealing metal pipes. The intumescent will not be able to crush a metal pipe in the same way it can a plastic pipe. You are likely to need a more specialist collar like our Pacifyre® EFC Endless Fire Collar or a pipe wrap or sleeve.
Why are intumescent pipe wrap systems wrapped in polythene?
Flexible strips of high performance intumescent material encapsulated in a polythene sleeve – designed for wrapping around plastic pipes that pass through masonry floors and walls. On exposure to fire the wrap expands rapidly inwards to squeeze the collapsing plastic pipe until the aperture is completely sealed.
What is intumescent sealant?
Intumescent Sealants Acrylic intumescent seals expand to fill a cavity when subjected to extreme heat and provide an extra layer of fire-resistant material to protect the structural integrity of a building.
Is silicone sealant fire resistant?
Silicone is both heat and flame resistant. Thanks to the unusual chemical properties of silicone as plastic – it doesn’t catch fire very easily and it doesn’t act as a conductor of heat, which means that it is fairly fire-resistant.
What are intumescent collars?
QWR CE Marked Intumescent Fire Collars prevent the spread of fire where PVC, HDPE & PP pipes penetrate fire compartment walls and floors.
What is intumescent mastic fireproofing?
The passive fire protection of a building provides a compartment for containing fire and smoke. These systems help protect firefighters and emergency responders during emergency operations by maintaining the structural integrity of the building during a fire event.
How does intumescent sealant work?
An intumescent seal is a strip of material fitted around a doorway, that when exposed to heat, expands closing any gaps around the door to stop the fire spreading for a period of time. These seals usually come with either 30 or 60 minute ratings.
What do you need to know about intumescent pipe collars?
On metal pipes, intumescent pipe collars dissipate heat away from fire-attacked copper and steel pipes, preventing heat spread and damage to property. Simple to fit, here at Rawlins Paints’ we also carry pipe covers that can be fitted in areas that are hard to access or properly secure pipe collars into place.
How are pipe collars used in fire protection?
Use fire collars on pipes passing through walls and fire barriers to help prevent the spread of smoke and fire. The pipe collars fit to surface openings, expanding in fire to crush plastic and thin aluminium pipes to fill the space and stop smoke and flames penetrating.
