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;
- a lower seal support disposable between a lower portion of the sealing sleeve and the lower tubing:
- an inner lower seal disposable axially between a lower end of the tubing union and the lower seal support and disposable radially between a protruding member of the lower seal support and the lower tubing;
- an outer lower seal disposable axially between the lower end of the tubing union and the lower seal support and disposable radially between the protruding member of the lower seal support and
- the sealing sleeve, wherein the lower seal support is configured to restrain axially outward expansion of the outer lower seal and the inner lower seal;
- at least one upper seal disposable proximate an upper end of the tubing union between the sealing sleeve and the upper tubing, and wherein 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;
- and
- a fluid path 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.
