Abstract
A multi-component C-ring coupling is provided that includes a connector, an internal C-ring, and a lower ring. In one embodiment, the multi-component C-ring coupling may include a diverter connector to weldlessly couple a diverter to a pipe, such as a conductor. In other embodiment, the coupling may include a casing housinghead connector to couple to a casing housinghead. The lower ring may be engaged with the connector via axial fasteners. The lower ring and connector may include angled internal surfaces to exert radial forces on the C-ring and cause engagement of the teeth of the C-ring with the outer wall of a pipe.
Claims27
A system, comprising:
- a slip lock connector, comprising:
- a C-ring having teeth facing inwardly toward a central axis;
- a first connector portion disposed circumferentially about the central axis;
- a second connector portion disposed circumferentially about the central axis, wherein the C-ring is disposed axially between the first and second connector portions;
- and
- at least one fastener between the first and second connector portions, wherein the at least one fastener is configured to move the first and second connector portions axially toward one another to cause a radial inward movement of the C-ring toward the central axis, wherein the slip lock connector comprises at least one of a seal test port configured to test at least one annular seal, a visual inspection gap configured to enable visual inspection of the C-ring, or a combination thereof.
A system, comprising:
- a slip lock connector, comprising:
- a C-ring facing inwardly toward a central axis;
- a first connector portion disposed circumferentially about the central axis wherein the first connector portion comprises one or more lateral fluid ports;
- a second connector portion disposed circumferentially about the central axis, wherein the C-ring is disposed axially between the first and second connector portions;
- and
- at least one fastener between the first and second connector portions, wherein the at least one fastener is configured to move the first and second connector portions axially toward one another to cause a radial inward movement of the C-ring toward the central axis.
A system, comprising:
- a slip lock connector, comprising:
- a C-ring facing inwardly toward a central axis;
- a first connector portion disposed circumferentially about the central axis;
- a second connector portion disposed circumferentially about the central axis, wherein the C-ring is disposed axially between the first and second connector portions;
- and
- at least one fastener between the first and second connector portions, wherein the at least one fastener is configured to move the first and second connector portions axially toward one another to cause a radial inward movement of the C-ring toward the central axis;
- wherein the slip lock connector is configured to surround and couple to a tubular component with the first connector portion extending across an end of the tubular component and the C-ring offset from the end of the tubular component.
