The invention relates to pipework (10, 12) for sprinkler systems comprising pipes (20, 24, 26, 28, 32) leading from a supply line (14) conveying extinguishing liquid and displaceable about mutually parallel axes (44, 46; 48, 50) with a union running from the supply line and an end pipe (28) to which a sprinkler head can be fitted. In order to ensure that the displaceable pipes are highly variable it is proposed that at least one of the pressurised displaceable pipes is a U-shaped pipe (20, 26), the arms (18, 22) of which are connectors for at least one further pipe (24, 28) and/or the union (16) which is pressure-tightly secured to the U-shaped pipe via plug-in connectors (34, 36, 38, 40, 42).
L'invention concerne une tuyauterie (10, 12) pour installations à têtes d'extinction automatiques qui comprend des tuyaux (20, 24, 26, 28, 32) qui partent d'une conduite d'alimentation (14) acheminant un liquide d'extinction et peuvent être déplacés autour d'axes (44, 46; 48, 50) parallèles. Ces tuyaux comprennent une pièce de raccordement partant de la conduite d'alimentation et un tuyau terminal (28) pouvant être muni d'une tête d'extinction. Afin de parvenir à une grande variabilité en ce qui concerne les tuyaux déplaçables, il est prévu qu'au moins un des tuyaux déplaçables sous pression soit un tuyau en U (20, 26), que ses branches latérales (18, 22) constituent des cavités pour recevoir au moins un autre tuyau (24, 28) et/ou la pièce de raccordement (16) qui est raccordée de manière étanche à la pression au tuyau en U, par l'intermédiaire d'éléments de raccordement emboîtables (34, 36, 38, 40, 42).
