Abstract

The invention discloses a monitoring probe, system and method for corrosion damage of a pressure pipeline. The monitoring probe comprises a corrosion sheet, a strain measurement sheet, a strain data transmission cable, and a sealing assembly. The corrosion sheet comprises an incident flow surface and a detection surface, the incident flow surface and the detection surface are respectively arrangedat two opposite sides of the corrosion sheet, the incident flow surface is exposed out of the sealing assembly, the detection surface is arranged in the sealing assembly in a sealing manner, and thematerial of the corrosion sheet is the same as that of a pressure pipeline to be measured; the strain measurement sheet is arranged in the sealing assembly in a sealing manner and is electrically connected with the detection surface; one end of the strain data transmission cable is arranged outside the sealing assembly, one end of the strain data transmission cable is arranged in the sealing assembly in a sealed mode, and the strain data transmission cable is electrically connected with the strain measurement sheet. During measurement, the monitoring probe and the reference probe are used in cooperation, the corrosion damage state of the corrosion sheet is monitored through the strain difference value between the monitoring probe and the reference probe, and therefore the corrosion damagestate of the pressure pipeline can be accurately monitored.

Description

technical field [0001] The invention relates to the technical field of pressure pipeline monitoring, in particular to a pressure pipeline corrosion damage monitoring probe, system and method thereof. Background technique [0002] Pressure pipelines are widely used in shipbuilding, petrochemical, nuclear power and other fields. Depending on the application field, the internal environment of the pressure pipeline is diverse, such as the pressure seawater pipeline in the ship field, the secondary circuit high-pressure steam pipeline in the nuclear power field, and the oil and gas transmission pipeline in the petrochemical field. 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 internal medium of the pressure pipeline is the main factor leading to the thinning and leakage of the pipeline. Real-time monitoring ...
