Abstract
A pipe system has a pipe with an axis and a retainer groove formed in an exterior of the pipe near an axial end of the pipe. The pipe system also has a tubular body with an interior and one end sized to receive the axial end of the pipe therein to form a pipe assembly. The pipe system also has a retainer configured to be received in the retainer groove and to be both axially movable and radially movable relative to the retainer groove during formation of the pipe assembly and to retain the pipe and the tubular body in the pipe assembly.
Claims20
A pipe system comprising:
- a pipe having an axis and a retainer groove formed in an exterior of the pipe near an axial end of the pipe;
- a tubular body having an interior and one end sized to receive the axial end of the pipe therein to form a pipe assembly;
- and
- a retainer configured to be received in the retainer groove,
- wherein the retainer is configured to be both axially movable and radially movable relative to the retainer groove during formation of the pipe assembly and to retain the pipe and the tubular body in the pipe assembly,
- wherein the retainer includes a base and a tail extending from a radial outer surface of the base, and
- wherein the tail is configured to radially extend from the base and radially collapse toward the base to permit formation of the pipe assembly when collapsed and retain the pipe assembly when extended.
A pipe system comprising:
- a pipe having an axis, an exterior, and a retainer groove formed in the exterior;
- a retainer configured to be mounted in the retainer groove, wherein an entirety of the retainer is configured to be both axially movable and radially movable relative to the retainer groove during formation of a pipe assembly;
- and
- a tubular body having an interior configured to receive the pipe to form the pipe assembly, the tubular body having a second retainer groove on the interior and configured to receive at least a portion of the retainer when the pipe assembly is formed,
- wherein the tubular body is another pipe or a coupling,
- wherein the retainer includes a base and a tail extending from a radial outer surface of the base, and
- wherein the tail is configured to radially extend from the base and radially collapse toward the base to permit formation of the pipe assembly when collapsed and retain the pipe assembly when extended.
