Due to the dual effects of the badness and complexity of the marine environment in service of the pipeline and the damage and leakage of the pipeline, not only great economic loss can be brought to enterprises, but also the marine environment and the natural ecology can be seriously damaged. Therefore, the hose delivery test is a problem of major concern in the oil extraction industry at present, the pressure test is taken as an indispensable test step of the delivery test, and the whole pressure-bearing performance and the axial tensile capacity of the hose are tested through the pressure test. The sealing effect of the plugging device has great influence on the accuracy of the experimental data of the internal pressure test, and the disclosed plugging device is suitable for pipeline laying and maintenance processes, and realizes pipeline plugging under the working condition that oil gas of the pipeline is not continuously pressed through structures such as internal expanding type fixing, wedge-shaped reinforcement locking, linkage sealing of an oil cylinder group and the like. If the device is used for a hose pressure test wound on the storage disc, the structure is complex, the manufacturing cost is high, and a valve cannot be installed due to the fact that only the pipeline is sealed. In the pressure test, the pressure for pressing the pipeline needs to be strictly controlled, so that the method is not suitable for the pressure test of the pipeline.
The present patent application provides a plugging device suitable for a marine hose joint pressure test on the background.
