Pipeline water pressure test system and test method

Abstract

The invention provides a pipeline water pressure test system and a test method, which relate to the technical field of conveying pipeline safety measurement. The systemcomprises a bottom supporting plate which is horizontally placed on the ground, the top end of the bottom supporting plate is provided with a supporting rib plate erected at the top end of the bottom supporting plate, a horizontally-fixed top supporting plate is arranged at the top end of the supporting rib plate, a plurality of through long holes are formed in the top end of the top supporting plate, every two adjacent long holes are formed in the top end of the top supporting plate at equal intervals, and threaded lead screws parallel to the long holes are arranged at the top end of the top supporting plate. An exhaust hole is formed in the middle of anair nozzle,a guide plate is hinged to the inner wall of the exhaust hole, the angle of the guide plate in the exhaust hole is controlled by the guide plate through a third adjusting screw, the blowing-out direction of the exhaust hole is controlled by changing the swing angle of the guide plate, airflow is guided to the outer wall of the pipeline, impurities on the outer wall of the pipeline are removed, and operation simplicity is improved.

Description

technical field [0001] The invention relates to the technical field of transportation pipeline safety measurement, in particular to a pipeline hydraulic test system and test method. Background technique [0002] After the production of the pipeline is completed, the pipeline should be subjected to a hydrostatic test according to the design requirements. The main purpose of the pressure test is to check the mechanical properties, tightness and vacuum holding performance of the pipeline. Except for the vacuum pipeline system and the special pipeline system with fire protection requirements, most pipelines only have strong requirements on the strength and tightness of the pipeline. In order to test the mechanical properties and strength tests of pipelines, hydrostatic testing is generally used. [0003] At present, the method for testing the mechanical properties of pipelines is mainly to inject water pressure into the pipeline for testing, such as a pipeline water pressure te...

AI Technical Summary

Problems solved by technology

[0004] At present, the pipeline is full of water pressure inside, and the pipeline wall will expand and crack. The existing expansion of the pipeline is mainly through the observation of the pipeline wall with the naked eye. It is unqualified to observe the expansion and thickening of the pipeline wall. During the test, the pipeline Sometimes the wall will only produce a small amount of expansion, which is difficult to directly observe with the naked eye, which may easily lead to inaccurate tests and affect the safety of the pipeline in later use
