Abstract
A system may include a sealing sleeve disposable about a tubing union joining a lower tubing and an upper tubing, at least one lower seal disposable proximate a lower end of the tubing union between the sealing sleeve and the lower tubing, and at least one upper seal disposable proximate an upper end of the tubing union between the sealing sleeve and the upper tubing. The at least one upper seal, the at least one lower seal, and the sealing sleeve form a pressure test cavity about the tubing union. The system may also include a fluid path configured to provide fluid communication between the pressure test cavity and a pressure test port.
Claims20
A system, comprising:
- a sealing sleeve disposable about a tubing union joining a lower tubing and an upper tubing;
- at least one lower seal disposable proximate a lower end of the tubing union between the sealing sleeve and the lower tubing;
- at least one upper seal disposable proximate an upper end of the tubing union between the sealing sleeve and the upper tubing, and wherein at least one upper seal, the at least one lower seal, and the sealing sleeve form a pressure test cavity about the tubing union;
- and
- a fluid path configured to provide fluid communication between the pressure test cavity and a pressure test port.
A system, comprising:
- a sealing sleeve disposable about a tubing union joining a lower tubing and an upper tubing;
- a lower seal disposable proximate a lower end of the tubing union between the sealing sleeve and the lower tubing;
- an upper seal disposable proximate an upper end of the tubing union between the sealing sleeve and the upper tubing;
- and
- at least one seal support disposable proximate the upper seal, the lower seal, or some combination thereof, and wherein the at least one seal support, the upper seal, the lower seal, and the sealing sleeve form a pressure test cavity about the tubing union;
- a fluid path extending through the at least one seal support, wherein the fluid path is configured to provide fluid communication between the pressure test cavity and a pressure test port;
- and
- a support housing disposable about the sealing sleeve, wherein the support housing is configured to restrain outward expansion of the sealing sleeve in response to pressure increasing within the pressure test cavity.
A system, comprising:
- An extended lower seal having a first end disposable about a lower tubing proximate a lower end of a tubing union, wherein a second end of the extended lower seal is disposable about an upper tubing proximate an upper end of the tubing union, and wherein a central portion of the extended lower seal is disposable about the tubing union and extends between the first end and the second end of the lower seal;
- an upper seal support disposable proximate the upper end of the tubing union between the second end of the lower seal and the upper tubing;
- an upper seal disposable between the upper seal support and the upper tubing proximate the upper end of the tubing union, wherein the upper seal, the upper seal support, and the lower seal form a pressure test cavity about the tubing union;
- a fluid path extending through the upper seal support, wherein the fluid path is configured to provide fluid communication between the pressure test cavity and a pressure test port;
- and
- a support housing disposable about a tubing union joining a lower tubing and an upper tubing, wherein the support housing is configured to restrain outward expansion of the central portion of the extended lower seal in response to pressure increasing within the pressure test cavity.
