    摘要: The invention relates to an intumescent fire sleeve for a conduit, such as a pipe, a cable or a device penetrating a wall, a ceiling or a floor in a building, said fire sleeve comprising at least one layer (4) of intumescent material and one carrier (5) being connected to the layer of intumescent material, and said fire sleeve having a length (L) that at least corresponds to a circumference of the conduit for which it is intended. The carrier is made of at least one wire (10) having spring-loaded characteristics. In a non-applied position, the carrier has the ability to coil onto itself in a spiral manner. The invention also relates to a coil of such intumescent fire sleeves and to a method for installation of such an intumescent fire sleeve.
