Abstract

The invention provides a pipeline damage detection device and a pipeline damage detection method, wherein the pipeline damage detection device comprises: an installation pipe; an air bag, the air bag has a connecting end arranged in the installation pipe, and a measurement protruding from the installation pipe a hydraulic injection structure, which penetrates through the opposite ends of the airbag in the length direction and is sealedly connected with the airbag; the hydraulic injection structure has an input end and an output end, and the output end is used to send the airbag to the airbag. The pipeline to be tested is filled with fluid; and a guided wave sensing device is provided at the measurement end for transmitting and receiving guided waves to detect the damage of the pipeline to be tested. The pipeline damage detection device and pipeline damage detection method provided by the invention can increase the friction force between the outer surface of the airbag and the pipe wall by installing a pipe externally, which can meet the requirements of high-pressure pipeline damage detection, improve the work efficiency of the pipeline damage detection test, and reduce the test workload.

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 inspection method and ultrasonic inspection method are usually used. For the pipeline passing through the bulkhead structure, when there is insufficient construction space on one side of the bulkhead, the damage detection construction can only be carried out on the other side of the bulkhead. The ultrasonic flaw detection method cannot be applied because it cannot access 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 cause inaccurate detection results due to the interference of the metal parts. SUMMARY OF THE INVENTION [0003] ...
