Abstract (en)

[origin: EP2253354A1] The element has a metal pipe (10) for transporting water, and a series of sprinklers (20), each comprising a threaded base (22) and a sprinkling head (21). The pipe is formed of a closed cylindrical wall (11) provided with a series of sockets (12) formed from a material by deformation of the wall. The sockets tightly assemble the bases of sprinklers. A series of raising rings is placed between the sprinkler and the respective socket of the pipe, so as to limit penetration of the bases into an inner space of the pipe. The bases have chosen axial length for limited penetration into the space. Independent claims are also included for the following: (1) a method of manufacturing a pipe for a protection system against fire by sprinklers (2) a method of manufacturing a protection network that protects against fire by sprinklers.
