Abstract

The invention provides pipeline damage detection equipment and a pipeline damage detection method. The pipeline damage detection equipment comprises a mounting seat, a sealing element, a hydraulic injection structure and a detection device, wherein the measuring end of the sealing element is used for extending into a to-be-detected pipeline to seal the to-be-detected pipeline; the hydraulic injection structure is provided with an input end and an output end, and the output end is used for filling the to-be-detected pipeline with fluid; and the detection device comprises a fiber grating sensor and a controller, the fiber grating sensor is arranged at the measuring end, and the detection device is used for receiving a stress signal of the to-be-detected pipeline so as to detect the pipeline damage condition of the to-be-detected pipeline. According to the pipeline damage detection equipment and the pipeline damage detection method provided by the invention, the friction force between the outer surface of the sealing element and the pipe wall is increased through the external mounting seat, so that the high-pressure pipeline damage detection requirement can be met, and the test workload is reduced while the working efficiency of the pipeline damage detection test is improved.

Description

technical field [0001] The invention relates to the technical field of pipeline damage detection equipment, in particular to a pipeline damage detection device and a pipeline damage detection method. Background technique [0002] At present, in the construction of pipeline damage detection, radiographic flaw detection method and ultrasonic flaw detection method are usually used. For pipelines passing through the bulkhead structure, when there is insufficient construction space on one side of the bulkhead, damage detection can only be carried out on the other side of the bulkhead. The ultrasonic flaw detection method cannot be applied because it cannot approach the damaged part; the construction space is insufficient When there are other metal parts directly attached to the pipeline on the side of the bulkhead, the radiographic inspection method will be interfered by the metal parts, resulting in inaccurate detection results. Contents of the invention [0003] The inventio...
