Abstract
A system including a connector system configured to couple a first tubular to a second tubular comprising a sleeve configured to couple to the first tubular, wherein an inner diameter of the sleeve comprises a coupling feature, a lock ring configured to couple to an exterior surface of the second tubular and radially engage with the coupling feature of the sleeve, a piston ring configured to energize the lock ring into engagement with the sleeve, a first pressure ring configured to couple to the second tubular, wherein the first pressure ring is axially beneath the piston ring, and a second pressure ring disposed about the piston ring and configured to couple to the second tubular.
Claims20
A system, comprising:
- a connector system configured to couple a first tubular to a second tubular, comprising:
- a sleeve configured to couple to the first tubular, wherein an inner diameter of the sleeve comprises a coupling feature;
- a lock ring configured to couple to an exterior surface of the second tubular and radially engage with the coupling feature of the sleeve;
- a piston ring configured to energize the lock ring into engagement with the sleeve;
- a first pressure ring configured to couple to the second tubular, wherein the first pressure ring is axially beneath the piston ring;
- and
- a second pressure ring disposed about the piston ring and configured to couple to the second tubular, wherein the second pressure ring is configured to move along the piston ring.
A system, comprising:
- a mineral extraction system, comprising:
- a first tubular;
- a second tubular;
- and
- a connector system configured to couple the first tubular to the second tubular, comprising:
- a sleeve coupled to the first tubular, wherein the sleeve comprises:
- a coupling feature formed on an inner diameter of the sleeve;
- a first pressure port extending from an outer diameter of the sleeve to the inner diameter of the sleeve, wherein the first pressure port is configured to fluidly connect with a first pressure chamber of the connector system;
- and
- a second pressure port extending from the outer diameter of the sleeve to the inner diameter of the sleeve, wherein the second pressure port is configured to fluidly connect with a second pressure chamber of the connector system;
- a lock ring coupled to the second tubular and configured to radially engage with the coupling feature of the sleeve;
- and
- a piston ring configured to energize the lock ring into engagement with the sleeve.
A method, comprising:
- landing a first tubular against a second tubular;
- pumping hydraulic fluid through a first pressure port of a sleeve coupled to the first tubular and into a first pressure chamber fluidly coupled to the first pressure port to drive a piston ring between a lock ring and the second tubular, wherein a first outer seal is disposed between the piston ring and the sleeve and a first inner seal is disposed inside of an inner diameter of the piston ring;
- and
- driving the lock ring radially outward with the piston ring to engage a first coupling feature of the lock ring with a second coupling feature of the sleeve to couple the first tubular to the second tubular and block relative axial movement between the first tubular and the second tubular.
