Astroflame 4″ 110mm AFPC110 240 minute PFP Fire Rated Intumescent Pipe Collar
£8.83 (£7.36 ex. VAT)
Astro PFP Pipe Closer are designed to maintain the fire resistance of fire rated walls and floors where these are breached by continuous plastic pipes. Astro PFP Pipe Closer can be used in gypsum, masonry and concrete walls and with concrete 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 applicationof the pipe and/or the installation environment. The code defining if a pipe is capped is stated after the fire classification. For instance EI 60 C/U which means the pipe was capped inside the furnace, and uncapped outside the furnace. The test configuration defines the approvals possible.
