ASTRO PFP PIPE CLOSER

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 application of 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.

Features and benefits:

• CE and UKCA Marked.
• For pipe sizes from smallest pipes available to Ø315 mm with a wide range of pipe wall thicknesses.
• Smaller pipes can be fitted within larger closers with the benefit of accommodating pipes that are at an angle or if the opening around the pipe is too large.
• Fire classifications up to 240 minutes for both integrity and insulation.
• Certified for PVC-U, PVC-C, PE, LDPE, MDPE, HDPE, ABS,SAN+PVC and PP pipes and a wide range of composite plastic pipes.
• Tested for U/U pipe end applications.
• For internal use.
