摘要： An inflatable stent for use in the repair and maintenance of pipes such as water or gas supply pipes, or for use as a medical device comprises an inflatable portion having an inner and outer membrane. When inflated, the inner and outer membranes are radially spaced apart to define an annular space there between. The inner membrane defines a passage between a first and second end and the outer membrane defines a first diameter (D1) of the stent. The inner and outer membranes are connected by a plurality of connecting members in the annular space. End caps are disposed on the first and second ends of the stent which connect the inner and outer membranes. The inflatable portion further comprises an inflatable pipe or lumen engaging portion that defines a second, larger diameter (D2) of the stent, when inflated.

摘要： A system and method for pipe insertion in live gas mains includes isolating a section of the gas main and taking measurements of service line connection points. This data is then used to prepare a pipe to be inserted into the gas main by drilling holes and applying fittings at the appropriate locations. The prepared pipe is then inserted into the gas main and the service lines are connected to it without the need to excavate the street over each service connection. The inserted pipe is then fluidly connected to the cut ends of the gas main and gas flow is routed through the newly inserted pipe and the attached service lines, while gas continues to flow through the original portions of the gas main that still remain in service.

摘要： A method of in-situ pipeline replacement in which valves, fittings, and other obstructions are removed from an existing pipeline, a heat-fusible polymer pipeline having an initially deformed configuration less than the existing pipeline diameter is inserted into the remaining portions of the existing pipeline and reformed to substantially conform to the inside diameter of the existing pipeline, heat-fusible fittings are provided to replace removed portions of the existing pipeline and heat-fused to the polymer liner, and transition fittings provided to operably connect the replacement pipeline to those portions of the existing pipeline not within the replacement scope. The completed replacement polymer pipeline creates an operable wetted pressure boundary within the bounds of the replaced existing pipeline.

摘要： A method for cutting an opening in the side of a pipe carrying gas under pressure, providing a bypass through the cut, and terminating the bypass when the pipe has been repaired, and apparatus for performing steps of the method. A branching saddle is bonded to the pipe, and a fixture is mounted on the pipe at the saddle. The fixture comprise a barrel through which various tool-insertion assemblies may be inserted.The tool-insertion assemblies tyically include a shaft carrying a tool on one of its ends, a driving hub affixed near its opposite end, and a sealing plug slidably mounted axially on the shaft between the tool and the driving hub. The tools enter into the fixture's bore through a tool inlet, into which the sealing plug of the insertion assembly is screwed for a pressure-tight fit. The tools are individually inserted, in succession, through the fixture's bore and through the wall of the pipe. Lowering of the tools by means of the insertion assemblies into and out of the pressurized pipe is made possible by manipulation of a gate valve in the fixture, which allows the upper part of the bore to be depressurized prior to removal and during the insertion of different ones of the insertion assemblies.

摘要： A method of performing a servicing operation within a pipeline comprises positioning a swellable component about at a desired location within a pipeline, exposing the swellable component to a swelling agent within the pipeline, expanding the swellable component into sealing engagement with the pipeline, thereby forming a seal across the pipeline, and opening a fluid pathway through the pipeline without removing the swellable component. Another method of performing a servicing operation within a pipeline comprises inserting into the pipeline a pipeline tool comprising an externally mounted swellable component, propelling the pipeline tool through the pipeline to about a desired location via a flow of fluid, expanding the swellable component into sealing engagement with the pipeline at about the desired location, and opening a flow path through the pipeline tool.

摘要： A method of replacing a gas main that supplies gas to a recipient through an existing service line includes connecting a first tapping tee to the new gas main and connecting a second tapping tee to the existing service line that communicates with a downstream recipient. Branch passages of the first and second tapping tees are fluidically connected together by a connecting conduit. The new gas main is then tapped with the first tee so that gas flows from the new gas main into the connecting conduit up to the second tee. All air is bled from the connecting conduit between the first and second tees, and the existing service line is then tapped with the second tee so that gas is supplied to the recipient through both the existing service line and the connecting conduit. Gas flow to the recipient from the old main is then terminated. The second tee is a specially configured tapping tee specifically adapted for bleeding air from the connecting conduit that interconnects the first and second tees. This tee also utilizes a non-cylindrical bore for holding the conduit to be tapped to inhibit collapsing of the conduit during tapping operations.

摘要： A method of sealing a pipe and a device for sealing the pipe which prevents gas leakage out of a pipe stub plugged by a stopper disposed in a tee fitting, to allow a permanent cap to be welded onto the pipe. The device comprises an expandable plug comprising a pair of plates with a sealing member disposed between the plates. The plates can be squeezed together, for example by tightening nuts onto bolts extending through the plates to compress the sealing member and cause the periphery of the sealing member to expand against the inner wall of the pipe. Stabilizing means, for example a nut having a reverse thread and a complimentary tool, is provided for stabilizing the expandable plug radially within the pipe as the plates are squeezed together. The expandable plug is inserted into the pipe stub after the bypassed section of pipe has been removed, and lodged in the pipe by squeezing the plates together to expand the sealing member against the inner wall of the pipe stub. The cap is then welded onto the pipe stub.
