Title (EN) IMPROVED ROTARY SHOULDER CONNECTIONS FOR THREADED PIPE CONNECTIONS
(FR) RACCORDS D'ÉPAULEMENTS ROTATIFS AMÉLIORÉS POUR RACCORDS DE TUYAUX 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 nose inner radius, 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 curved primary box shoulder; a curved primary pin shoulder and/or a curved secondary box shoulder and a curved secondary pin shoulder is disclosed. Methods of using the rotary shoulder connection are also disclosed.
(FR) La présente invention concerne un raccord d'épaulement rotatif comprenant : un raccord femelle, le raccord femelle ayant un rayon externe femelle, un rayon de contre-alésage femelle et un rayon interne femelle, et des filetages femelles ayant une forme de filetage femelle découpée le long d'un cône femelle ; un raccord mâle, le raccord mâle ayant un rayon interne d'embout mâle, un rayon externe mâle, un rayon de cylindre mâle et un rayon d'embout mâle, et des filetages mâles ayant une forme de filetage mâle découpée le long d'un cône mâle pour s'aligner avec les filetages femelles à l'intérieur du raccord femelle ; et un raccord d'épaulement primaire comprenant : un épaulement femelle primaire incurvé ; un épaulement mâle primaire incurvé et/ou un épaulement femelle secondaire incurvé et un épaulement mâle secondaire incurvé. L'invention concerne également des procédés d'utilisation du raccord d'épaulement rotatif.
