Abstract: The present disclosure relates to an insert and system of installing the same. The insert includes a tapered core and a cylinder. The core releasably secures to an installation device which includes a depth stop or a depth control to control the installation depth of the insert. The insert may be provided in a tray that allows for easier handling of the inserts and installation thereof in installation holes, for example in a hydraulic manifold. In some cases, the core includes a threaded hole to releasably secure the insert to the installation device, thus allowing the installation device to pull the core into the cylinder. The core and cylinder may be made of metallic materials such as steels, steel alloys and others. In some cases the insert can withstand blow out pressures of 40,000 psi or higher.

Abstract: An apparatus for plugging a bore of a tube sheet, the apparatus includes cantilevered members that project radially outward from a body on the inner surface of the tube sheet. Slots can be drilled into a tube the projects into the bore and the cantilevered members set into the slots. The cantilevered members can slide radially outward from within the body, or can be pivotingly attached on an end of the body. One end of a bolt threadingly attaches to the body, and attaches on its other end to a nut circumscribing the tube sheet bore on its outer surface. A deformable collar circumscribes the bolt between the body and nut and provides a seal within the tube sheet bore. The apparatus can also be used to plug bores that do not include tubes.

Abstract: A hydraulically installed tube plug with or without O.D surface enhancements and plug installation tooling, high pressure fluid system and method. The invention stops leaks in tubes with a plug that utilizes controlled high pressure fluid within the plug itself to radially expand the plug in place. Other plugs and plugging systems rely on mechanical methods for setting the plugs in the tubes with little or no control on the radial pressure applied to the tube. This lack of radial pressure control can result in a tubesheet ligament being over stressed (plastically deformed) or not enough pressure applied to stop the leak. The plug high pressure expansion tooling is designed with built in safety components that allow high pressure hydraulic expansion methods to be used safely in blind holes. The high pressure fluid system's design allows it to be used in hazardous environments.

Abstract: A plug for sealing a bore in the wall of a high-pressure fluid container is provided. The plug includes a sloping surface adapted to seal at an edge between surfaces of different diameter. A method for sealing the bore by forming a socket in the wall that is adapted to receive the plug is provided. The socket may be formed by reaming a tapered hole to form a surface having a minimum diameter greater than the diameter of the bore and tapping a segment of the tapered hole. A ball may be forced into a cup of the plug to increase radial force between the plug and the socket.

Abstract: The tube plug comprises a substantially cylindrical sheath closed at one end and having a relatively smooth outer surface and a central cavity. An expandable shell is received within the central cavity of the sheath. An expander member is adapted to expand the shell from within by being axially translated within the shell, the expander member also being adapted to grip the inner surface of the shell to retain the expander member in the expanded position. The outside surface of the shell is preferably provided with a plurality of lands. A second embodiment of the tube plug comprises a sleeve, a closed shell member adapted to be inserted within the sleeve, and an expander member contained within the shell. Upon axial translation of the expander member within the shell, the shell is expanded into contact with the sleeve and the sleeve is expanded into contact with the tube, thereby sealing the tube.
