Pipe Collars - CE
Astro PFP Pipe Closer - CE Marked. Designed to maintain the fire resistance of fire rated walls and floors where these are breached by continuous plastic pipes, and may be used in gypsum, masonry and concrete walls and floors. Each pipe closer consists of a Red/Silver coated circular steel shell that splits in two to fit around the service penetrations by means of a simple 'slide-lock' system.
The steel shell contains a graphite based reactive material which reacts when exposed to heat closing the openings left by the softening plastic pipe in fire. When testing pipes, one can choose not to cap (or close) the pipe, or cap the pipe inside the furnace, or outside the furnace, or on both sides. The configuration chosen depends on the intended application of the pipe and/or the installation environment.
The CE Pipe Collars are designed and tested to seal service penetration apertures containing plastic pipes or cables, 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 to 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.
