  • Patent number: 10214923
    Abstract: According to one embodiment a sealing plug is provided that includes an elastic body and a stem assembled coaxially with respect to one another. The elastic body is suitable for being expanded radially by pulling on the free end of the stem, which projects out of the elastic body, once it is inserted into the hole to be plugged, the elastic body applying a closing pressure against the hole. The sealing plug also comprises an empty space, arranged between the elastic body and the stem, which is communicated with the outside, such that the entrance of fluid into the elastic body is allowed so that the fluid applies pressure against the elastic body, thereby increasing the closing pressure applied by the elastic body against the hole.

  • Patent number: 10094479
    Abstract: This inventions relates to a plugging machine and a rigid tube provided with a stationary disc integral with the bottom of the tube and oriented almost orthogonal to the tube, with a movable disc paired with the stationary disc. A sealing ring of a resilient material is located between the discs and compressed when the movable disc is pressed against the stationary disc to adhere to an inner surface of the pipeline. The sealing ring is coaxial with respect to the pipeline. The movement of the movable disc is determined by raising or lowering a control rod within the tube by means of sloping sliders made in the lower portion of the rod which engage in respective grooves, likewise sloping, made in an axial shank associated with the movable disc and sliding inside an axial opening of the stationary disc. A component of a force is generated which is parallel to the axis of the discs. The axis is raised or lowered by rotation of a threaded ring engaging in a threading mate at the top of the rod.

  • Publication number: 20120155599
    Abstract: A method and apparatus for securely fastening a pipe collar or a bracket to a riser pipe of a boiling water reactor (BWR) jet pump assembly. A pipe plug assembly includes an angled pipe plug that acts as a wedge to expand a bushing assembly as the pipe plug is drawn into the overall pipe plug assembly. Expansion of the bushing assembly allows a tight tolerance to exist between an outer diameter of the pipe plug and an inner diameter of the collar/bracket and riser pipe. Expansion of the bushing assembly allows a straight hole to be match drilled into the collar/bracket and riser pipe, thereby avoiding a more complicated tapered hole to be drilled into the collar/bracket and riser pipe. An ensuing tight fit between the pipe plug assembly, the collar/bracket and the riser pipe mitigates vibration of components and minimizes leakage to acceptable levels for use in the flooded environment of the annulus region where the jet pump assembly exists in the BWR.

  • Patent number: 8001988
    Abstract: A method according to this invention employs a set of valves, a series of pressure checks, and a physical stop for verifying the closing of a locking system of a cylindrical passageway. The method may also employ an equalization piping. The valves isolate a tapping machine, a pipeline, and the equalization piping from one another so that product cannot flow from one to the other. The valves are then opened as a series of pressure checks are performed. A completion plug is then lowered into the passageway until the plug comes to rest within the passageway and is oriented so that a locking ring of the plug is in a filly expanded position. The expanded position is then confirmed by raising the plug until its upward travel is restricted. The plug is then released and pressure above the plug is reduced to 0 psi gauge.

  • Publication number: 20100307604
    Abstract: Various embodiments of the present invention provide apparatuses and methods for stopping the flow of media within a pipeline. The pipeline generally includes one or more pipes connected end-to-end, where each of the pipes has a longitudinal axis with an annular wall. The annular wall has an outer wall surface and an inner wall surface, where the inner wall surface defines an inner pipe diameter. In various embodiments, a hole is formed in the pipeline substantially perpendicular to the longitudinal axis of the annular wall and extending through the opposing pipe wall. A resilient plug is positioned within the pipeline such that it extends between the holes and is selectively expanded in a radial direction to create a seal with the inner surface of the pipe and holes to prevent flow of the media within the pipe.

  • Patent number: 7841364
    Abstract: A pipe plug comprised of two, pivotally connected plugging heads, each plugging head having a sealing element, which work in combination to double block and bleed a pipe. The first sealing element prevents flow of product in the pipe and the second sealing element captures any leakage past the first sealing element and forces that leakage out through a fitting. A stabilization pad, connected to a flange on a nosepiece of each plugging head, prevents deformation of the sealing elements. A spring-loaded pivot arm connected to the second plugging head allows the yoke that connects the two plugging heads to rotate freely. An outward-facing raised taper projection on the pivot arm, along with a guide wheel connected to the first plugging head, prevent the yokes and plugging heads from becoming entrapped during their installation in or removal from the pipe.

  • Patent number: 7740028
    Abstract: A composite plug system and a process to repair a hole in a tubular pipe. The process includes the steps of inserting a fastener through an opening in an oblong inner plate having an elongated diameter and a shorter diameter. The oblong plate is inserted into the pipe hole wherein the elongated diameter is greater than a diameter of the pipe hole and wherein the shorter diameter is less than the pipe hole diameter so that the oblong plate is within the tubular pipe beneath the hole. An initially liquid adhesive filler is applied over the oblong inner plate over the pipe hole. An outer plate having a central opening and a diameter larger than the pipe hole diameter is affixed over the pipe hole so that the central opening receives the fastener. The outer plate is secured to the oblong inner plate and the tubular pipe with the fastener until the adhesive filler solidifies. After the filler solidifies, the oblong plate and the outer plate are structurally bonded to the pipe wall through adhesion.
