摘要： A method, system and tools for introducing a fiber optic conduit into a pressurized gas pipeline includes the step of introducing a translating member into the pressurized gas pipeline via an entry port in a first fitting attached to the pressurized gas pipeline. Tools are deployed within a first pressure lock housing attached to the first fitting by using a first manipulator located in the first air lock housing. The translating member, such as a duct rod, is advanced within the pressurized gas pipeline by a driving mechanism until a second drilling fitting is reached. The translating member is attached to a fiber optic conduit or cable. The duct rod and fiber optic conduit are then pulled back through the pressurized gas pipeline. Extractor tools extending through seals in the pressure lock housing engage with and withdraw the duct rod. Alternatively, first and second duct rods may be pushed towards each other from the first and second fittings. End elements on the duct rods engage each other. The first duct rod is then pulled back, pulling the second duct rod with it. This technique can double the installation length available by pushing duct rod through the pipeline.

摘要： A method of introducing a fiber optic conduit into a pressurized gas pipeline includes the step of introducing a translating member into the pressurized gas pipeline via an entry port in a first drilling nipple attached to the pressurized gas pipeline. Tools are deployed within a first pressure lock housing attached to the first drilling nipple by using a first manipulator located in the first air lock housing. The duct rod is advanced within pressurized gas pipeline by a driving mechanism, until a second drilling nipple is reached. The translating member is attached to a fiber optic conduit. The duct rod and fiber optic conduit are then pulled back or pulled forward through the pressurized gas pipeline by the driving mechanism. A conduit is installed in a gas service line, to line the cable or conduit in a natural gas main pipeline to a telecommunications panel in a building.

摘要： A method of routing a new pipe duct into an existing pressurized gas pipeline includes the step of introducing a translating member into the pressurized gas pipeline via an entry port in a first fitting attached to the pressurized gas pipeline. The translating member, such as a duct rod, is advanced within the pressurized gas pipeline by a driving mechanism, until it reaches second fitting. The translating member is attached to a pipe inner duct. The duct rod and pipe inner duct are then pulled back through the pressurized gas pipeline by the driving mechanism.

摘要： A method of introducing a fiber optic conduit into a pressurized gas pipeline includes the step of introducing a translating member into the pressurized gas pipeline via an entry port in a first drilling fitting (18) (8, 70, 250, 300) attached to the pressurized gas pipeline. Tools are deployed within a first pressure lock housing (30) attached to the first drilling fitting by using a first manipulator (34) located in the first air lock housing. The duct rod is advanced within pressurized gas pipeline by a driving mechanism (60), until a second drilling fitting (80) is reached. The translating member is attached to a fiber optic conduit or cable. The duct rod and fiber optic conduit are then pulled back through the pressurized gas pipeline by the driving mechanism. A conduit or cable is installed in a gas service line, to provide an optical fiber between an optical fiber trunk line or ring and building.

摘要： Pipeline stopping tools for use in temporarily stopping flow in a pipeline have features for centering a conduit or cable within the pipeline. The conduit or cable is guided into a recess, to avoid damage as the pipeline is squeezed closed. Alternative pipeline stopping stools have features for sealing against both the inside walls of the pipeline and against the cable. In a first tool, a linkage on a handle drives seal lips on a seal ring to engage around and seal against the cable in the pipeline, while the outer edges of the seal ring seal against the inside walls of the pipeline. The linkage includes jaws which force the seal lips against the cable. In a second tool, a resilient seal is attached over a center plate and side plates pivotably attached to the center plate. A linkage drives the center plates from an open to a closed position. A cable recess in the seal ring seals against the cable while the outside edges of the seal ring seal against the pipeline. A third tool has a resilient plug and lips positioned around a cable recess. As the plug is forced into the pipeline, the lips seal around the cable, and the plug sidewalls bulge outwardly to seal against the pipeline.
