Abstract:
A piping diagnostic device according to an exemplary aspect of the present invention includes: criteria distribution generating means for generating a criteria distribution that is statistical data of criteria data of piping based on construction information about the piping, design information about the piping, and material information about the piping; changed-state distribution generating means for generating a changed-state distribution that is statistical data of changed-state data of the piping that have changed due to aging based on at least either vibration or dynamic pressure of the piping that have changed due to aging; measurement means for measuring at least either vibration or dynamic pressure of the piping; and determining means for determining deterioration of the piping based on the criteria distribution, the changed-state distribution, and at least either vibration or dynamic pressure of the piping.
