These CE Pipe Collars are designed and tested to seal service penetration apertures containing plastic pipes, using thermoplastic composites based on graphite intumescent technology. Developed to provide a high volume expansion and pressure seal during a fire. The X Series CE Collar offers EI120 and EI240 tested in accordance with EN1366-3 : 2009, the maximum diameter being 250mm, the ultra thin design of Astro X Series Collar shell gives a depth of 30mm and 40mm ensuring that they can be installed into the tightest of locations. The Pipe Collar can be installed on flexible or rigid wall and rigid floor constructions. It can also be used with Astro Batt systems.
They are compatible with polypropylene (pp), polyethylene (PE) and Polyvinylchoride (PVC) pipes. The Collar is tested with end capping configurations that cover U/U, C/U, U/C and C/C pipes. These CE Pipe Collar is used around combustible pipes to form a penetration seal used to reinstate the fire resistance performance of wall and floor constructions, where they have been provided with apertures for the penetration of combustible pipe services. The CE Pipe Collar include an intumescent component incorporated into a mild steel case to close any gaps and joints and provide a closure of combusting pipes when heated and to prevent the passage of fire. They are supplied in assembled form, without fixings. The collar is wrapped around the pipe at the soffit or both faces of walls, depending on application.
