> Product Description

CE and UKCA Label Intumescent Pipe CloserAstro 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.

Our engineering judgment based on EN 1366-3:2009 are:

Intended use of pipe Pipe end condition 4)
Rainwater pipe, plastic At drainage U/U 1)
Not at drainage C/C 1)
Drainage or sewage pipe, plastic Ventilated drain U/U 1)
Unventilated drain U/C 1)
Drain w/water trap U/C 1)
Unventilated drain C/C 2)
Pipe in closed circuit (water, gas, air, electricity etc.) C/C 2)3)
Flue gas recovery system pipe, plastic U/C 1)
Pipe with open ends and ≥ 50cm length on both sides, plastic U/U 2)
Pipe supported by suspension system, metal Fire rated support C/U 1)
Non-fire rated U/C 1)
Waste disposal shaft pipe, metal U/C 1)

1) Suggested in EN 1366-3:2009. 2) Judgment based on tests.
3) Metal pipes should have fire rated support. 4) U/U classified fire seals cover C/U, U/C and C/C. C/U classified fire seals cover U/C and C/C. U/C classified fire seals cover C/C.

> Competency

It is vital that those entrusted to design or install a fire stopping product have the necessary levels of competence to undertake the task professionally and thoroughly. The level of competency required will be commensurate with the expected complexity of the building. All designers must eliminate, reduce or control foreseeable risks that may arise during installation, construction or maintenance when preparing or modifying designs. Clients should ensure that the principal designer and principal contractor carry out their duties under CDM regulations. The ASFP foundation course in passive fire protection provides essential knowledge as part of demonstrating competency and understanding in this key fire protection specialism.
