摘要： A buried piping replacement period prediction apparatus includes a buried piping attribute data acquisition unit and an exceedance-probability-of-corrosion-depth prediction unit. The buried piping attribute data acquisition unit acquires attribute data of buried piping. The attribute data of the buried piping includes a first environmental factor of the buried piping, a first burial period of time of the buried piping, and a nominal pipe wall thickness or an allowable corrosion depth of the buried piping. The exceedance-probability-of-corrosion-depth prediction unit calculates an exceedance probability of corrosion depth of the buried piping in a certain period from an exceedance-probability-of-corrosion-depth prediction model for the first environmental factor, the first burial period of time, and the nominal pipe wall thickness or the allowable corrosion depth.
