THREADED TUBULAR ELEMENT FOR FATIGUE RESISTANT THREADED TUBULAR JOINT AND RESULTING THREADED TUBULAR JOINT
The invention concerns a threaded tubular element whereof the thread comprises at least a tangential connecting zone with multiple radii (21) at the thread root, in particular on the bearing flank (13). Said zone (21) comprises a main arc (23) of radius (rP1) whereof the circle intersects the flank...

| description | The invention concerns a threaded tubular element whereof the thread comprises at least a tangential connecting zone with multiple radii (21) at the thread root, in particular on the bearing flank (13). Said zone (21) comprises a main arc (23) of radius (rP1) whereof the circle intersects the flank (13) in one point (PRF1). The tangent in (PRF1) to said circle forms a strictly positive angle (D) with the flank (13). The secondary arcs (25, 27) of radii (rS1, and rT1) less than (rP1) provide the tangential connection of the main circle on the side of the flank (13), on the other side of the thread root (19). The radius (rP1) is greater than that (rH1) of the standard circle (29) which passes through (PRF1) and which would constitute alone a tangential connection zone. Such a threaded element provides a tubular threaded joint wherein it is integrated with good resistance to static as well as cyclic loads.
Le filetage de l'élément fileté tubulaire comporte au moins une zone de raccordement tangentiel à rayons multiples (21) en fond de filet, notamment du côté flanc porteur (13). Cette zone (21) comprend un arc de cercle principal (23) de rayon (rp1) dont le cercle support coupe le flanc (13) en un point (PRF1). La tangente en (PRF1) à ce cercle fait un angle strictement positif (D) avec le flanc (13). Les arcs de cercle secondaires (25, 27) de rayons (rS1, et rT1) inférieurs à (rP1) effectuent le raccordement tangentiel de l'arc de cercle principal d'un côté au flanc (13), de l'autre côté au fond de filet (19). Le rayon (rP1) est supérieur à celui (rH1) du cercle standard (29) qui passe par (PRF1) et qui constituerait à lui seul une zone de raccordement tangentiel. Un tel élément fileté procure à un joint fileté tubulaire qui l'incorpore une bonne résistance aux sollicitations tant statiques que cycliques. |
