摘要： A pipe retrieval machine includes a frame defining a decoupling region and a travel axis and a transporting mechanism supported on the frame. The transporting mechanism has a first gripping structure adjacent an infeed end of the machine and a second gripping structure adjacent an outfeed end of the machine. The decoupling region is between the first and second gripping structures. The machine has a drive system to move the first and second gripping structures at a steady state speed to direct a pipe along the travel axis. The pipe retrieval machine includes one or more safety features to stop the drive system either automatically or through manual action, one or more safety features to inhibit or prevent damage to components of the decoupling region in the event of a malfunction, or both. Methods of operating a pipe retrieval machine include any of the operation procedures, method steps, safety features, and/or functions as described and in any combination.

摘要： 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.

摘要： 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.

摘要： A pipe system can include a coupling having an axis, axial ends and a bore. Each axial end can include a coupling spline groove formed in the bore, and a seal groove axially inboard of the coupling spline groove. The seal groove can be configured to house a seal. At least two pipes can be configured to be inserted into different axial ends of the coupling and be secured therein with retainers. Each pipe can include a pipe spline groove, a band groove axially adjacent to and radially shallower than the pipe spline groove, and a band mounted in the band groove.

摘要： 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.

摘要： A polymeric riser cap member includes a central tubular section defining a generally cylindrical bore for receiving a sprinkler riser, the central tubular section having open top and bottom ends, and an annular skirt coaxial with the central tubular section and having an inner diameter larger than an inner diameter of the central tubular section. The annular skirt has an inner surface having internal threads threadably connectable with the externally threaded surface of a tubular riser adapter member of a tubular coupler. The bottom end of the central tubular section has an annular projection disposed opposite and spaced from a portion of the annular skirt. The riser cap member includes an annular recess adapted to receive a seal located in a wall extending laterally between the annular skirt and the annular projection.

摘要： 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.

摘要： 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.

摘要： A polymer pipe includes a length between a first end and a second end, the length and the first end having a first diameter. The second end is a belled or female end having a second diameter larger than the first diameter. An insert device is received within the second end and has an annular body formed of a body material and has a spline portion formed as a part of the insert device. The spline portion includes a spline carried by the insert device and resiliently movable in a radial direction relative to an axis of the annular body.
