Abstract
A non-destructive monitoring method for internal pressure intensity of a pipeline. The method establishes an equation relationship by the fact that the variation of the internal diameter of the pipeline is the same as that measured by FBG sensors, and can effectively obtain the value of the internal pressure intensity of the pipeline by measuring the strain values of the FBG sensors installed on the pipeline so as to monitor the internal pressure intensity of the pipeline. The present invention has the advantages of simple principle, convenient installation, no damage to pipeline structure, long-distance real-time on-line monitoring and the like, and can measure the pressure intensity of various pipelines with different diameters by changing the calibration distance of sensors and the dimension of sensor clamps. This can complete non-destructive, real-time and accurate monitoring on the internal pressure intensity of the pipeline.
