Abstract

Un segment de verrouillage à être utilisé pour raccorder deux longueurs de tuyau comporte un talon s'étendant radialement et servant à la rotation. Par l'accouplement du frein dans une dépression annulaire, c.-à-d. en étant placé entre deux parois, la rotation du segment peut continuer jusqu'à ce que les points sur le frein calent entre les deux parois. La rotation du segment en réponse aux pressions de poussée croissantes peut donc être arrêtée avant que la rotation n'entraîne le segment à exercer sur le bout uni une force radiale vers l'intérieur assez grande pour pénétrer ledit bout uni.
