EN Certified Intumescent Pipe Collar
The Pipe Collar is made up of a metallic casing of 0,7 mm thick of galvanised steel or 0,5 mm of stainless steel with attached intumescent graphite sheets of 4mm thick and 30 or 60 mm wide, depending on the collar diameter.
Under the influence of fire, the expandable graphite strip swells and blocks the opening in the plastic pipe, which prevents fire or smoke spreading across various fire sectors.
