Abstract (en)

[origin: WO9918303A1] Disclosed is a fireproofing system for any size of combustible pipe or conduit that passes between and through walls and floors. The entire length of a combustible pipe or conduit (1), on each side of a wall or floor is covered with a fire resistant blanket (4). The blanket consists of a temperature resistant, inorganic, heat insulating layer (4a), which is covered by a fire retardant, heat absorbing material (4b). Larger pipes are additionally covered with intumescent fire retarding materials (4d). Near the wall or the floor, a pipe closing mechanism is to be placed on the top of the blanket (4). The closing mechanism is to be activated by the softening of the combustible pipe from the heat in the event of a fire. Such mechanisms include heat shrinkable materials (8a), weights (14, 14a) and springs (15, 18a) including spring hose clamps (20).
