​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.
