Abstract
Pour vérifier les joints réunissant un tube à bout mâle à filetage conique à un manchon (ou autre tube) à bout femelle à filetage conique, on visse une bague calibre sur le bout mâle 10 avec un couple donné correspondant sensiblement au serrage à la main et on marque sur le tube un repère il correspondant à la profondeur de vissage, on répète l'opération avec un calibre tampon sur le manchon (repère 13). Ensuite, pour obtenir la profondeur de vissage correspondant au serrage à la main, il suffit de vérifier que les marques tracées sur les deux éléments se trouvent à une distance fixe K1 + K2 , que l'on vérifie au moyen d'une réglette étalonnés. Ce stade une fois atteint, on sait qu'il suffit de visser d'un certain nombre de tours connus (longueur NP) pour obtenir un joint bloquéTo check the joints joining a male end tube with a conical thread to a sleeve (or other tube) with a female end with a conical thread, a gauge ring is screwed onto the male end 10 with a given torque corresponding approximately to the tightening by hand and a mark II corresponding to the screwing depth is marked on the tube, the operation is repeated with a buffer gauge on the sleeve (mark 13). Then, to obtain the screwing depth corresponding to hand tightening, it suffices to check that the marks drawn on the two elements are at a fixed distance K1 + K2, which is checked by means of a calibrated strip. Once this stage has been reached, we know that it is sufficient to screw a certain number of known turns (NP length) to obtain a blocked seal.
