Metal cylindrical clamp mounted on a pipe.
Cover made of single or
multi-segment stainless steel.

Intumescent material begins expanding
in the heat
and seals the hole.
Prevents the spread
of fire to adjacent compartments.
Up to EI 180 C/U, U/C
Environment class: Z2
Fire collar should be stored in a dry place with the temperature ranging from +5°C to +30°C for no longer than 24 months.
Description & use
Piro Collar PC is a metal cylindrical flexible clamp mounted on a pipe. It consists of an outer cover made of a single or multi-segment stainless steel sheet and one or more inserts made of intumescent material, which in fire conditions increases its volume and closes the opening. The steel cover is equipped with a lock, used to fasten the collar and stabilize it on the pipe, and with mounting brackets with holes through which steel expansion bolts are led, fixing the collar to the partition. The collar is delivered in the form of a ready-made product or in the form of an assembly kit for self-cutting and assembly during work on the site. Collars can be 60, 180 mm high. The height of the collar depends on the diameter of the pipe or its intended use.
Piro Collar PC is a product intended for fireproof sealing of penetration seals and mixed penetration seals in walls and floors of plastic pipes without insulation or with FEF or PE foam insulation, metal pipes insulated with FEF or PE foam, electric cables. The possible fire resistance class of ranges from EI 30 to EI 180. With the use of Piro Collar PC, it is possible to seal single pipes or pipe bundles, pipes in groups of e.g. 4 pieces, cable bundles, pipe bends that are mounted just below the floor. Other necessary information can be found in the ETA. Due to its good fireproof properties, Piro Collar PC is used for sealing pipes with particularly large diameters and where large thicknesses of flammable insulation on steel pipes are required. The product is intended for professional use.
Types of partitions where penetration seals
can be made using Piro Collar PC
FLOOR: Floors built of concrete or reinforced concrete, with a thickness of not less than 150 mm and a density of not less than 1700 kg/m3
RIGID WALL: Walls built of concrete, (reinforced, cellular) solid brick, hollow or checkered brick, with a min. thickness of 100 mm or 125 mm and a min. density of 600 kg/m3
FLEXIBLE WALL: Walls with a minimum thickness of 125 mm, with a skeleton structure built of steel or wooden sections
to fit all typical
25 - 400
Need a larger diameter?
Single stainless steel cover
Multi-segment stainless steel cover (fire collar built by means of Piro Collar PC L mounting set)
The internal diameter of the fire collar should be fitted to the external diameter of the protected installation element:
pipe | insulation | cable
it is required to install two fire collars
on both sides of the partition
it is required to install only one fire collar
underside of the floor
