Intumescent pipe collar providing up to four hours fire protection to plastic pipework.
Designed to reinstate the fire resistance performance of wall and floor constructions where they are penetrated by various combustible pipe services.
Intumescent pipe collars 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. PFC Corofil Intumescent Pipe Collars have been tested to EN 1366-3 and offer 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 30 mm deep and 40 mm deep and up to 250 mm 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.
