[0002] With the sustained and rapid development of my country's economy, the demand for energy continues to increase, and the construction of oil and gas field pipelines is also increasing. The protection of oil and gas field pipeline corrosion has become more and more important, which is directly related to the anti-corrosion performance and service life of the pipeline. Chemical corrosion is not very harmful, and the main reason for the appearance of convex holes and even perforations on the surface of steel pipes comes from electrochemical corrosion. When the metal undergoes an electrochemical reaction, the part with lower electrode potential is prone to lose electrons and become an anode; the part with higher electrode potential gains electrons and becomes a cathode. In the presence of O2 and H20, Fe(OH)2 generates hydrated iron oxide, that is, corrosion occurs. For the detection of the thickness of pipeline anti-corrosion coating, there are many detection schemes and detection tools in the industry. When the common oil and gas field pipeline corrosion detection device on the market is used outdoors, the display screen will be covered with dirt and dust, which is more laborious to remove, and the outer surface of the pipeline is curved. During the detection, it needs manpower support, which is not convenient enough, and frequent lifting is required during frequent detection. Utility Model Content
