Abstract
A system including a first tubular with a first fluid passage configured to receive a fluid for use in a mineral extraction system, a second tubular surrounding the first tubular, a protective cover coupled to the second tubular with a shear pin, wherein the second tubular is configured to move the protective cover from a first axial position to a second axial position, and the protective cover is configured to form a first seal around the first fluid passage; and a retainer coupled to the first tubular or the protective cover and configured to couple the protective cover to the first tubular.
Claims25
A system, comprising:
- a mineral extraction system, comprising:
- a first tubular comprising a first control fluid passage with a first fluid inlet;
- a second tubular comprising a second control fluid passage with a first fluid outlet, wherein the second control fluid passage is configured to fluidly couple to the first control fluid passage to supply a control fluid when the second tubular is in a first axial position;
- a protective cover system configured to protect the control fluid in the first control fluid passage, comprising:
- a protective cover;
- and
- one or more seals on the first tubular or the protective cover;
- wherein the second tubular couples to the protective cover and is configured to move the protective cover into a sealing position around the first fluid inlet when the second tubular moves along an axial path of travel from the first axial position to a second axial position, wherein the sealing position of the protective cover blocks undesirable fluids from entering the first control fluid passage.
A system, comprising:
- a first tubular comprising a first fluid passage and a second fluid passage configured to receive one or more fluids for use in a mineral extraction system;
- a second tubular surrounding the first tubular;
- a protective cover coupled to the second tubular, wherein the second tubular is configured to move the protective cover from a first axial position to a second axial position, and the protective cover is configured to form a first seal around the first fluid passage and a second seal around the second fluid passage;
- and
- a retainer coupled to the first tubular or the protective cover and configured to couple the protective cover to the first tubular.
A method, comprising:
- moving a protective cover between a first axial position and a second axial position via movement of a first tubular coupled to a tool along an axial path of travel, wherein the tool, the first tubular, or a combination thereof, comprises one or more first control fluid passages;
- enabling flow of a control fluid between the one or more first control fluid passages and one or more second control fluid passages in a second tubular in the first axial position of the protective cover;
- and
- sealing the one or more second control fluid passage in the second tubular in the second axial position of the protective cover, wherein sealing comprises blocking undesirable fluids from entering the one or more second control fluid passages.
