Service Penetrations

PFC Corofil Intumescent Pipe Collar CIPC

Fire stopping for service penetrations containing single plastic pipes

PFC Corofil Intumescent Pipe Collars are designed and tested to provide a fire-resistant seal in flexible walls, rigid walls, rigid floors, and PFC Corofil Coated panels where they have been penetrated by service penetrations containing plastic pipes and metallic pipes with insulation.

Tested to EN1366-3, PFC Corofil Intumescent Pipe Collar offers fire resistance periods of up to EI240 for differing services and wall / floor constructions.

They are manufactured with an intumescent coating incorporated in a thin steel casing which are available 30mm and 40mm deep and up to 250mm diameter. In the event of a fire the intumescent will expand when heated, providing a closure of combustible pipes to prevent the passage of fire between compartments.

PFC Corofil Intumescent Pipe Collars are supplied in assembled form without fixings. The collar is wrapped around the pipe at the soffit or on both sides of the wall. The annular gap around the pipes should be sealed using PFC Corofil Acoustic Intumescent Sealant.

Where should you use an Intumescent Pipe Collar?

You can use PFC Corofil Intumescent Pipe Collars to reinstate the fire resistance performance of wall and floor constructions where they are penetrated by certain combustible pipes, single pipes only.

The specific elements of construction that PFC Corofil Intumescent Pipe Collars may be used with are detailed in the technical data sheet.
