Publication number: 20220205335Abstract: An actuatable sealing mechanism for sealing a fluid channel provided between two co-axially arranged tubular members having a central longitudinal axis. The actuatable actuable sealing mechanism comprises an elastomeric seal, an axially moveable actuating sleeve member (1400, 2400, 3020) and a radially moveable activating member. The activating member is configured to be moveable in a radial direction in use to translate the actuatable sealing mechanism between an unsealed state and a sealed state. When it is in the sealed state, the activating member axially compresses the elastomeric seal sufficiently to expand the elastomeric seal in the said radial direction to seal the fluid channel.Type: ApplicationFiled: May 1, 2020Publication date: June 30, 2022Applicant: Oil States Industries (UK) LimitedInventors: Miguel Fernandes Martins, Richard Johnston

Patent number: 9334988Abstract: A pipe connector comprises a first pipe section having a first end and having teeth formed on its outer surface proximate to, but spaced axially apart from, the first end. A second pipe section has a second end which, in use, is to be connected to the first end of the first pipe section. A sleeve is slidably mounted on the outer surface of the second pipe section for movement between a first extended position, in which a front end of the sleeve projects beyond the second end of the second pipe section so as, in use, to overlap the first end of the first pipe section when abutted against the second end of the second pipe section, and a second retracted position in which said front end is withdrawn so as at least to be aligned with the second end of the second pipe section, the sleeve having teeth formed on its outer surface at least in the region of the front end. A stop is provided on the second pipe section and the sleeve to prevent axial movement of the sleeve beyond the extended position.Type: GrantFiled: May 8, 2014Date of Patent: May 10, 2016Assignee: Oil States Industries (UK) LimitedInventors: John Gallagher, Martin James Ward
