Title (EN) IMPROVED ROTARY SHOULDER CONNECTIONS FOR THREADED PIPE CONNECTIONS
(FR) RACCORDS ROTATIFS À ÉPAULEMENT AMÉLIORÉS POUR RACCORDS DE TUYAU FILETÉS
Abstract:
(EN) A rotary shoulder connection comprising: a box connection, wherein the box connection has a box outer radius, a box counter bore radius and a box inner radius, and box threads having a box thread form cut along a box taper; a pin connection, wherein the pin connection has a pin outer radius, a pin cylinder radius and a pin nose radius, and pin threads having a pin thread form cut along a pin taper to align with the box threads inside the box connection; and a primary shoulder connection comprising: a primary box shoulder at a primary box angle from greater than about 0 to about 15 degrees with respect to a first perpendicular to a box axis at a first end point; a primary pin shoulder at a primary pin angle from about 0 to about 15 degrees with respect to the first perpendicular to a pin axis at the first end point is disclosed. Methods of using the rotary shoulder connection are also disclosed.
(FR) La présente invention concerne un raccord rotatif à épaulement qui comprend : un raccord de boîte, le raccord de boîte ayant un rayon externe de boîte, un rayon de contre-alésage de boîte et un rayon interne de boîte, et des filetages de boîte ayant une forme de filetage de boîte découpée le long d'un cône de boîte; un raccord à broche, le raccord à broche ayant un rayon extérieur de broche, un rayon de cylindre de broche et un rayon de nez de broche, et des filetages de broche ayant une forme de filetage de broche découpée le long d'un cône de broche pour s'aligner avec les filetages de boîte à l'intérieur du raccord de boîte; et un raccord à épaulement primaire comprenant : un épaulement de boîte primaire à un angle de boîte primaire situé dans la plage allant d'une valeur supérieure à environ 0 à environ 15 degrés par rapport à une première perpendiculaire à un axe de boîte au niveau d'un premier point d'extrémité; un épaulement de broche primaire à un angle de broche primaire situé dans la plage allant d'environ 0 à environ 15 degrés par rapport à la première perpendiculaire à un axe de broche au niveau du premier point d'extrémité. L'invention concerne également des procédés d'utilisation de raccord rotatif à épaulement.
