ACE Pipe Collars

Fire Penetration Sealing Systems


VS Pipe Collars are metal casings filled with intumescent wraps used around plastic pipes to create a fire barrier. This fire stop system is used around plastic civil pipes in buildings which would be located in shafts. In order to create a complete fire seal, the openings through which the pipes are passing through also need to be made fire proof in order to provide a full fire stop solution.

In the event of a fire, the wraps inside the collars expand multiple times to collapse inward and close the pipes thereby creating a complete fire seal. The three elements that feed a fire are oxygen, heat and fuel. If any one of these are restricted at the time of a fire, then the fire can be extinguished or controlled at the source. The aim of VS Pipe Collars is to stop the oxygen supply thereby preventing the fire from propagating further. The collars are available for standard plastic pipe sizes of 2", 3", 4", 6" & 8" diameters. The size of the metal collars and the thickness of the intumescent wraps depends on the diameter of the pipes. This product is tested as per ASTM E 814 & UL 1479.
