CE & UKCA Marked Intumescent 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 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.
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.

We have technical representatives who provide assistance in the selection and specification of the products on this site and should be consulted for exact installation and product suitability. Ensure an early engagement with ourselves, designers, main contractor and specialist installers before any installation. Other trades and/or manufacturers may need to be consulted. For in-depth information, specification and technical advice please call our Head Office on:
Telephone: +44 (0)1329 844 500 Email: sales@astroflame.com
All interested parties, designer, specifier, main contractor and specialist installers should provide access to allow the fire stopping seals to be regularly inspected and maintained, as well as records kept of such maintenance at minimum periods of 12 months, as required by the Regulatory Reform Order, and repaired if necessary. Reference should be made to ASFP TGD 17 – Code of Practice for the Installation and Inspection of Fire Stopping.
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.
