Abstract

The invention discloses a pressure pipeline corrosion damage monitoring probe, system and method, wherein the monitoring probe includes a corrosion sheet, a strain gauge, a strain data transmission cable and a sealing assembly; the corrosion sheet includes an upstream surface and a The detection surface, the upstream surface and the detection surface are respectively set on the opposite sides of the corrosion sheet. The upstream surface is exposed outside the sealing assembly, and the detection surface is sealed inside the sealing assembly. The material of the corrosion sheet is the same as that of the pressure pipeline to be measured The strain gauge is sealed in the sealing assembly, and the strain gauge is electrically connected to the detection surface; one end of the strain data transmission cable is placed outside the sealing assembly, and one end of the strain data transmission cable is sealed in the sealing assembly, and the strain data transmission cable It is electrically connected with the strain gauge; during the measurement, the monitoring probe is used in conjunction with the reference probe, and the corrosion damage state of the corrosion sheet is monitored by the strain difference between the monitoring probe and the reference probe, so as to realize the pressure Accurate monitoring of pipeline corrosion damage status.

Description

technical field [0001] The invention relates to the technical field of pressure pipeline monitoring, in particular to a monitoring probe, system and method for corrosion damage of pressure pipelines. Background technique [0002] Pressure pipelines are widely used in ships, petrochemicals, nuclear power and other fields. According to different application fields, the internal environmental media of pressure pipelines are various, such as pressure seawater pipelines in the field of ships, secondary circuit high-pressure steam pipelines in the field of nuclear power, and oil and gas pipelines in the field of petrochemicals. Regardless of the medium environment, the integrity of the pressure pipeline is the fundamental condition to ensure the safe operation of the system. From the perspective of operation, the corrosion damage caused by the medium inside the pressure pipeline is the main factor leading to the thinning and leakage of the pipeline. Real-time monitoring of the co...
