In order to reflect the real path of the deformation of the pipeline, the X, Y, Z triaxial angle sensors are arranged to cover the whole pipe system, as shown in fig. 2, X, Y, Z triaxial angle sensors are respectively installed at A, B, C, D, E points, when the unit starts to operate, the pipeline deforms under the action of the gravity of the heated and flowing medium, the triaxial angle sensors transmit the deformation data acquired by the triaxial angle sensors to the data processing module through the data transmission module, as shown in table 1, the data on 1, 2, 3, 4 and 5 in table 1 respectively correspond to the data acquired by the A, B, C, D, E point triaxial angle sensors.
