  • Publication number: 20210301954
    Abstract: A pipe restraining system has first and second pipes. Each pipe has an axis and a groove adjacent an axial end thereof. A bushing bridges and hydraulically seals with the first and second pipes. First and second clamp rings removably attach the bushing to a respective one of the first and second pipes. When the pipe restraining system is assembled, axial tensile loads passing through the first pipe are transmitted through the first clamp ring, the bushing, and the second clamp ring to the second pipe. An axial distance between the first and second pipes remains substantially constant.

  • Patent number: 11098834
    Abstract: An assembly includes a tubular body having an axis, an axial end, a bore that is axial an aperture and a retainer groove formed in the bore and contiguous with the aperture. The assembly also includes a retainer mounted in the retainer groove. The retainer has a debris shield located external to the tubular body. The retainer includes a nominal configuration wherein the debris shield is configured to close off access to the aperture and the retainer groove to prevent debris from accumulating therein. In addition, the retainer includes an expanded configuration wherein the debris shield is not configured to completely close off access to the aperture and the retainer groove.

  • Patent number: 10228056
    Abstract: A seal has a seal body with an axis and axial-facing surfaces. The seal body is configured to be mounted to a tubular member, and seal between the tubular member and a second tubular member. A visual indicium can be located on only one of the axial-facing surfaces. Prior to assembly of the tubular member and the second tubular member, the visual indicium is configured to be visible to a user after being correctly mounted to the tubular member without the user physically contacting the seal body.

  • Publication number: 20180216767
    Abstract: A retainer for a tubular body and a pipe in a pipe assembly can include a split ring having an axis, an outer diameter, a bore that is axial having an inner diameter, and first and second axial ends. The split ring can have a relaxed, default state wherein, relative to the axis, a default radius R1 of the split ring is less than an expanded radius R2 of the split ring when it is expanded in an actuated state. The radial size of the split ring can be configured to radially expand relative to the axis without manual intervention when the pipe is axially inserted through the split ring in the tubular body, such that the chamfer on the split ring is configured to translate axial motion of the pipe through the split ring into a radial motion of the split ring.

  • Publication number: 20180187810
    Abstract: Systems, methods and components for a tool-less, pre-assembled restrained joint for a pipe are disclosed. For example, a pipe can include a tubular member having an axis, a spigot on one axial end, a bell on an opposite axial end, an outer retainer groove in an outer surface of the spigot, and an inner retainer groove in an inner surface of the bell. A retainer comprising a split ring can be configured to be mounted in the inner retainer groove. The retainer can include a single annular finger cantilevered therefrom and circumscribing an entirety of the split ring in spring bias. The finger can be configured to engage the outer retainer groove of a second pipe in a pipe assembly.
