Abstract
In the development of the land and the ocean air extraction resource in China, because of the reasons that the foundation is not stable, the medium is corroded, the current flushes, the accident happen, etc, the pipeline generates defects easily, the pipeline is damaged easily, the oil gas is leaked out, and huge economy and ecological environmental protection loss is caused. Therefore, the welded seam and the defects must be tested periodically in the manufacturing, laying and operating process. The defects of the pipeline are discovered in time, the damage section is repaired, and the disaster accident is avoided. A throwing ejector and recovery device for apparatus of detecting defect in pipeline belongs to a new throwing and recovery special apparatus. The throwing ejector and recovery device for apparatus of detecting defect in pipeline comprises a high-pressure flange disk, a gate valve, a three-pass opening, a standard cylinder, a main canister, an exhaust stop valve, a pressure gauge, a cover plate, an evacuation stop valve, an injection pipe line, a balanced pipe line, an injection stop valve, and a balanced stop valve.
