摘要: L'invention est relative a un joint filete pour tubes d'acier utilisables en particulier l'industrie petroliere, du type dans lequel l'element male (3) et femelle (1) sont reunis par des filetages (4). The invention relates to threaded for steel usable in particular the petroleum industry, of wherein element and female are joined by threads (4) . tandis qu'une partie de la surface contour chaque filet fortement appliquee l'etat visse sur le filetage l'autre element. while portion each thread is strongly applied when screwed on other Un au moins elements comporte une distance axiale correspondant longueur d'au pas gorge (18) dont profondeur superieure hauteur filets, ou lesdites gorges etant munies d'un garnissage matiere synthetique volume forme correspondent jeu qui existerait entre cet les dimensions seraient limite tolerances d'usinage permet plus grand possible monte. At least one comprises an axial corresponding length at pitch groove whose depth greater than height threads, said or more grooves being fitted with lining synthetic material shape correspond play which would exist state between this seal be limit machining allow largest assembled state.
