摘要: This describes an apparatus for repairing a plastic transport pipe with a defective section while the pipe is under pressure. A pressure vessel encloses the defective section and seals with the pipe. The defective section is cut in two and the defective section drops out into the lower space of the vessel. A repair nipple is then moved into the space between the two cut ends of the pipe. Electrofusion collars are placed over the joint between the insert nipple and the cut ends of the transport pipe. The electrofusion collars are then energized to effect a leakproof joint between the insert nipple and the two ends of the transport pipe. The insert nipple may be any replacement section desired, such as a section with a Tee in it.

摘要: A pipeline bend detector pig for measuring a bend in pipeline is disclosed, the pig having an elongated flexible body for transposition through the pipeline. The body has an imaginary central axis that substantially remains coaxial with the pipeline cylindrical axis as the body transverses the interior of the pipeline. First and second length-measuring cables are supported to the body, each in a radial plane of and spaced from the body central axis and spaced angularly from each other. Each length-measuring cable has one end affixed to the body and a free end. Each cable has spring tension applied to the free end thereof to keep the cable taunt. A variable electrical resistance element is actuated by the free end of each cable as the free ends of the cables are moved by bends in the pipeline. An odometer for measuring the distance of travel of the pig is provided. A solid state memory records the distance traveled and the occurrence of bends in the pipeline.
