Technical Field

[0001] The utility model relates to the technical field of corrosion detection sampling, in particular to a pipeline corrosion detection sampling device. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Usually, the fluid is pressurized by blowers, compressors, pumps and boilers, and then flows from the high-pressure part of the pipeline to the low-pressure part. It can also be conveyed by the fluid's own pressure or gravity. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, water conservancy projects and various industrial installations. Due to the large span of pipeline laying and the fact that pipelines are often buried underground, the complexity of the pipeline laying environment is further increased. As the service life increases, the pipeline contacts various substances in the environment and other factors, causing it to be corroded and damaged. In order to analyze the cause of pipeline corrosion, it is necessary to sample and analyze the corroded pipeline. Utility Model Content
