Abstract

L'invention concerne un procédé de gestion de construction de joint d'étanchéité destiné à serrer par réglage d'une pluralité d'emplacements de serrage sur une bride qui enserre un joint d'étanchéité (12) et fourniture d'un boulon (6) et d'un écrou (8) lors du serrage de chaque emplacement, le couple à appliquer au boulon ou à l'écrou en fonction du nombre de circuits autour des emplacements de serrage ou de l'emplacement de serrage étant calculé ou sélectionné, le couple est réglé dans un outil de serrage (14) et le couple de sortie de l'outil de serrage est changé par étapes ou en continu en fonction du nombre de circuits ou de l'emplacement de serrage. De cette manière, la force axiale de chaque boulon peut atteindre la force axiale cible.
