Abstract

The present invention provides a hydraulic pressure test sealing tool and a hydraulic pressure test method for pipelines. The hydraulic pressure test sealing tool comprises a sealing plate and a position limiting clamper, wherein the sealing plate is adapted to the inner diameter of a pipeline, and can be filled in the pipe mouth of the pipeline, the position limiting clamper comprises a hoop hooped on the outer wall of the pipeline and a position limiting baffle positioned on one end of the hoop and perpendicular to the hoop, and the position limiting baffle extends along the axial line of the hoop so as to stop the sealing plate. According to the present invention, the sealing tool can seal the pipeline when the pipeline is subjected to the hydraulic pressure test, wherein the pipe mouth of the pipeline is filled and sealed with the sealing plate, and the sealing plate is subjected to stopping position limiting by clamping the pipeline on the outer side of the pipeline through the position limiting clamper, such that the pipeline sealing can be achieved without the flange structure, and the waste of the material, the working time and the labor due to the pipe section extending can be avoided; and the sealing tool has characteristics of simple structure, convenient production, convenient operation, recycling more times, and wide application range.

Description

technical field [0001] The invention relates to the technical field of pipeline reliability verification, in particular to a pipeline hydraulic test sealing tool and a hydraulic test method. Background technique [0002] In recent years, the number of LNG integrated modules has gradually increased. In order to meet its harsh working conditions, the number of flanges on the pipeline needs to be reduced as much as possible. In the pipeline hydrostatic test, the flange needs to be used to seal the pipeline. After reducing the flanges in the module, many interfaces will be the nozzles of the pipeline, and there will be no corresponding flanges to complete the test. [0003] The traditional solution is: lengthen the pipeline and add a flange to the lengthened pipeline section, and then cut off the redundant pipeline section after the hydrostatic test is completed. However, this method causes waste of materials and labor, and increases the cost. The drawbacks of this approach be...
