Piping diagnostic equipment, asset management equipment, piping diagnostic methods and piping diagnostic programs

摘要

Based on the piping information that specifies the configuration of the piping equipment to be diagnosed, the simulation execution unit 11 that executes the simulation of the pressure vibration in the piping of the piping equipment, and the piping from the simulation result of the pressure vibration and the pressure measurement data. A fatigue cycle analysis unit 12 for calculating the fatigue cycle of the above and an index calculation unit 13 for calculating an index indicating a pipe failure risk from the fatigue cycle analyzed by the fatigue cycle analysis unit 12 are provided. As a result, the degree of fatigue progress is obtained from the stress generated in the pipe and the number of times the stress fluctuation is repeated, and the pipe replacement time is estimated.
