Method and device for monitoring creep life of boiler main steam pipeline elbow and medium

The invention discloses a creep life monitoring method and device for a boiler main steam pipeline elbow and a storage medium, and the method comprises the steps: arranging strain rosettes on three target parts of the main steam pipeline elbow, and detecting the strain of the three target parts in real time; then, in combination with the strains of the three target parts, the pipeline stress of each part can be calculated in real time; and finally, calculating the total creep life loss of the pipeline according to the pipeline stress and temperature of each target part. On the basis, the method can be suitable for real-time monitoring of the creep life of the pipeline elbow, the problem that deformation of the high-temperature and high-pressure steam pipeline elbow cannot be monitored on line is solved, the deformation condition of the pipeline can be known in real time, and therefore the creep life loss rate of the pipeline is obtained; therefore, the method is high in real-time performance, can play a guidi
