Use of a passive fire alarm system for conduits and corresponding method.

摘要

The passive fire protection system comprises a moldable and flexible meshwork made of a non-combustible material with certain coefficient of thermal conductivity for extending the time span. A line section made of a material, particularly stainless steel, copper, aluminum or their alloys with certain coefficient of thermal conductivity in a fire protection installation remains below a critical temperature. The meshwork is a fabric, knit fabric or interlaced yarn. An independent claim is included for a method for extending the time span, in which a line section in a fire protection installation remains below a critical temperature.
