Description

Technical Field

[0001] The present invention relates to the technical field of pressure pipelines, and particularly to a pressure pipeline inspection device based on GIS positioning. Background Technique

[0002] Broadly understood, a pressure pipeline refers to all pipelines that bear internal pressure or external pressure, regardless of the medium inside the pipe. A pressure pipeline is a part of a pipeline, and a pipeline is used to transport, distribute, mix, separate, discharge, measure, control, and stop the flow of fluids. It is an assembly composed of pipes, pipe fittings, flanges, bolt connections, gaskets, valves, other components or pressure-bearing components, and supports. A pressure pipeline is a system that is interrelated and mutually influential. Pulling one hair moves the whole body. The length-diameter ratio of a pressure pipeline is very large, making it extremely prone to instability, and its stress situation is more complex than that of a pressure vessel. The fluid flow state inside a pressure pipeline is complex, with little buffering room, and the frequency of working condition changes is higher than that of a pressure vessel (such as high temperature, high pressure, low temperature, low pressure, displacement deformation, wind, snow, earthquake, etc. may all affect the stress situation of the pressure pipeline). There are a wide variety of pipeline components and pipeline supports, and each material has its own characteristics and specific technical requirements, making the material selection complex. The possible leakage points on a pipeline are more than those on a pressure vessel. Usually, there are five leakage points just for one valve. There are many types and a large number of pressure pipelines. The design, manufacturing, installation, inspection, and application management links are numerous, which is very different from pressure vessels.

[0003] Before a pressure pipeline is put into use, it is necessary to inspect the compressive resistance of the pressure pipeline. However, the current method for inspecting pressure pipelines is mainly manual inspection of the hardness and quality of the pressure pipeline, which results in low efficiency of manual inspection and unsatisfactory results, and improvement is needed.
