In this paper, mainly the old pipeline testing equipment, testing standards and repair techniques based, in more detail introduce several pigs with detector detection principle and detection methods. Corrosion for the pipeline status, testing pigs to determine the repair standards. According to the internal corrosion of the pipeline, the internal corrosion joint repair method, the in-situ cured lining repair method, the turnover lining method and the plastic pipe lining method are introduced. The purpose is to improve the technical level of domestic old pipeline repairing, Pipeline repair personnel to provide the theoretical basis for the detection and repair of the old pipe, for their reference and reference.
