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.

System, method and apparatus for ramped retainer for a pipe

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.

A pipe seal assembly includes a stiffener having an axis, an inner diameter (ID) and an outer diameter (OD). The seal assembly also includes an elastomer that is coupled to and extending though the stiffener, such that the elastomer is located on both the ID and the OD of the stiffener. A method of manufacturing a tubular member includes forming the tubular member with a female end; locating a seal assembly having an extension inside the female end, pressing the seal assembly into the female end to form a seal groove, belling the tubular member using the seal assembly to form a belled shape, and pressing the extension into the interior of the female end to form a spline groove inside the female end adjacent the seal groove; and then sacrificially removing the extension, but leaving the seal assembly to form a final assembly.

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 are 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.

A pipe system includes a tubular body having an axis, a bore extending in an axial direction, a tubular body retainer groove formed in the bore, and a tubular body exterior. Retainers are configured to be mounted in the tubular body retainer groove only from the bore of the tubular body. In one version, the retainers cannot be installed in the tubular body retainer groove from the exterior of the tubular body. The retainers are configured to be circumferentially spaced apart from each other with respect to the axis. In addition, a pipe having a pipe exterior with a pipe retainer groove is configured to receive the retainers to form a pipe assembly.

A pipe restrained joint seal and lock can include a ring that is continuous and annular. The ring can have an axis, a proximal end and a distal end axially spaced apart from the proximal end. A spline can extend from the ring to engage a spline groove of a tubular component. The spline can include one or more of the following features: a seal mounted to the distal end of the ring; the seal mounted to the ring axially distal of the spline; the seal mounted to the ring radially outward of the spline relative to the axis; and the seal mounted to the ring, the seal having a seal groove extending in a distal direction, and a portion of the ring is located in the seal groove.

A pipe system includes a pipe having an axis and a retainer groove formed in an exterior of the pipe. A retainer is mounted in the retainer groove. An entirety of the retainer is both axially movable and radially movable relative to the retainer groove during formation of a pipe assembly with a tubular body to form a pipe assembly.

A pipe coupling may include a body that is tubular and formed from a polymer. The body may include a main bore with a main axis and at least first and second female receptacles on each end of the main bore. Each receptacle may be configured to receive a male end of a pipe. A first brace may be coupled to and extend between, for example, a first female receptacle and a third female receptacle. A second brace may be coupled to extend between, for example, a second female receptacle and the third female receptacle. The pipe coupling can be a single, integral, injection molded monolithic structure.

A system for a basement concrete form and drainage are disclosed. The system may include a lineal that is a horizontal concrete form for a footer for a wall and a basement floor. The lineal may include a rectilinear tubular structure having a cavity, an outer wall, and drain perforations in the outer wall to permit fluid transmission from the cavity to an exterior of the lineal. In addition, a retainer may be mounted to a stake for the basement concrete form when the stake is embedded in a formation underlying the lineal. The retainer may be selectively vertically positioned along the stake to adjust a height of the lineal relative to the underlying formation.

System, method and apparatus for basement footer concrete forms and drainage-related components

A pipe may include a pipe body having an axis, an axial bore and a pipe body outer diameter. A male end may be formed on the pipe body. The male end can have an outer diameter consistent with the pipe body outer diameter, and an axial end face. A female end may be formed as an integral bell on the pipe body opposite the male end. The female end may have an inner diameter that is larger than the outer diameter of the male end, a seal recess on an interior thereof, and an interior feature in the interior of the female end that is complementary to the axial end face of the male end. The female end of a first pipe may be configured to receive the male end of a second pipe, such that the interior feature of the first pipe engages and restrains the axial end face of the second pipe. A coupling may be used to join two of the pipes.

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.

System, method and apparatus for seal marker

A pipe has an axis, a cylindrical portion, a cylindrical belled end and a conical transition portion between the cylindrical portion and the cylindrical belled end. A machine includes a body having an axis, a head configured to be complimentary in shape to the conical transition portion, a cutting portion configured to be complementary in shape to the cylindrical belled end, and the cutting portion is configured to rotate relative to the body and the pipe during formation of the groove to cut the groove inside the pipe.
