    摘要： A pipe plugger disclosed includes a sealing element that can be expanded inside the pipe to plug off a range of pipe diameters. The element is inserted into a pipe, relaxed and unexpanded, through an opening of uniform diameter. This allows pipe tapping equipment for cutting a side opening of one diameter to be used with a range of pipe sizes, which results in a considerable reduction in the equipment required to handle plugging operations in a variety of pipe diameters.

    摘要： A pipeline cleaning device comprising a body adapted to be moved forwardly through the pipeline, a plurality of springs mounted on the body, and a scraping element carried on each spring for engaging the inner wall of the pipeline in circumferentially spaced-apart relation. Each scraping element includes a base connected to the spring, a V-shaped blade upstanding from the base for tightly engaging the pipeline wall with its apex on the forward end thereof, and a relatively stiff rod extending from the base for tightly engaging at its outer end with the pipeline wall between the sides of the blade. Each of the base, blade, and rod is formed of urethane.

    摘要： Apparatus comprising a housing adapted to be connected to a pipeline for surrounding in fluidtight relation an area of the pipeline to be tapped and having an opening therein adapted to be connected with the opening to be formed in the pipeline. Each of one or more shaped charges is carried by a holder for disposal over the periphery of the area to be removed, and a fuse connecting with each charge extends exteriorly of the housing to permit the charge to be detonated in response to a signal from a remote location in order to cut the coupon from such area. A means is disposed entirely within the housing to withdraw the holder and the coupon into a portion of the housing removed from the path between the opening in the housing and the opening cut in the pipeline.

    摘要： A pipeline pig adapted to be propelled through a pipeline by fluid flowing therethrough wherein the pig has two spaced apart body supporting sections at least one of which has a curved or spherical surface which limits fluid flow past the pig when the pig is traversing a sharp bend (e.g., a 1.5 radius ell) in the pipeline.
