摘要： A device and method for plugging a tube that includes setting a tapered plug in a tube with a compression ring that circumscribes the plug. The ring radially expands when axially compressed and wedges the plug in the tube. An anchoring assembly fits over the tapered end of the plug and is coupled to the plug while being pushed against the compressed ring. When coupled to the plug, the anchoring assembly maintains the ring in a compressed state. The anchoring assembly can be made up of legs that fasten to the tapered end of the plug and have shoulders attached on a free end that are positioned against a lateral side of the compressed ring.

摘要： A method of obtaining a leakproof connection between a metallic tube having a leak and a metallic sleeve extending over the leak, includes expanding the sleeve being formed of a material having given strength values against an inner wall surface of the tube being formed of a material having strength values greater than the given values. In order to bridge a gap due to spring-back without the aid of an additional component of a shape memory alloy, a sleeve material having strength values lower than those of the material of the tube is used. A leakproof connection is obtained as the result of the greater spring-back of the tube.

摘要： A self cleaning plug is positionable within a tube having an internal surface with a defined dimension. The plug is formed of a first rigid member, a compressible member, a bolt, a second rigid member and a cleaning device. The first rigid member has a threaded bore and an external dimension less than the defined dimension of the tube internal surface. The compressible member has a through bore large enough to receive a shank of the bolt. The bolt extends axially through the compressible member and into the threaded bore of the first rigid member. The second rigid member is preferably in the form of a thin disk and is carried on the bolt between the compressible member and a head of the bolt, such that rotation of said bolt into said rigid member will result in axial compression and radial expansion of the compressible member. The cleaning device which is in the form of a wheel or disk and may be an abrasive material or a brush, has an external dimension greater than that of the rigid member and at least as great as the defined dimension so that it will engage the internal surface as the plug is being inserted into the tube. The cleaning device is carried on the plug either at a leading edge of the first rigid member or between the first rigid member and the compressible member.

摘要： A tool for removing a metal plug from a tube with repeated pulling impulses includes a pneumatic cylinder defining an interior, cylindrical chamber. A distal end surface of the cylinder defines an anvil. A cylindrical slug, or hammer, is sealingly slidable within the chamber in response to a pressure difference above and below the hammer within the chamber. The cylinder is rigidly connected to the plug so as to hang therefrom, the weight of the cylinder providing a static pull force working in conjunction with the pulling impulses. A pulling impulse is provided by first raising the hammer above the anvil by pneumatically creating a first pressure difference wherein the pressure below the hammer is greater than the pressure above the hammer, then creating a second pressure difference wherein the pressure below the hammer is no greater than the pressure above the hammer in order to drive the hammer against the anvil at speed. The tool is also adapted for disengaging an expander member engaged in a tapered plug shell with a mandrel that includes a push-rod having an end extending into the top of the chamber proximate the plug. Repeated displacement impulses are applied to the expander member by applying a different sequence of forces to the hammer so as to cause it to repeatedly strike the push-rod against the expander member. The tool and a method of using the tool are particularly suited to removing a plug from a heat exchanger tube in a nuclear powered steam generator.

摘要： A tube plug for closing a defective heat exchanger tube includes a hollow conical portion having a closed free end and a hollow cylindrical portion merging fluidly with the hollow conical portion without a step. The hollow cylindrical portion has an outer surface with an outside diameter being smaller than the inside diameter of the heat exchanger tube to be closed. The outer surface of the hollow cylindrical portion has a roughened region to be expanded into sealing contact with the inner surface of the heat exchanger tube. The roughened region has a peak-to-valley height of substantially between 0.05 and 0.2 mm. A device is disposed in the hollow cylindrical portion and/or the hollow conical portion for positioning and locking a pulling tool. A method for loosening a tube plug firmly retained in a heat exchanger tube by melting the surface of the wall of the tube plug along a predetermined path with a welding tool, and a method for closing a defective heat exchanger tube by inserting a tube plug and expanding a cold-formed roughened region of the cylindrical portion from inside and forcing the roughened region into locking contact with the inner surface of the heat exchanger tube, are also provided.
