Abstract
A wall-thickness thinning rate at a not-measured position is estimated using information having a small number of measured points. Simulation of behavior of fluid flowing inside a pipe line is performed based on wall-thickness data of pips and three-dimensional layout data of the pipe line including the pips using a computer, and simulated wall-thickness thinned data of the pipes composing the pipe line is calculated from change of the simulated behavior of fluid.

6. A system for predicting a thinned wall-thickness of a piping of a plant in which a wall-thickness of a piping is predicted under wall-thickness data in which a wall-thickness of piping parts of said plant is specified, the system comprising:
-
a wall-thickness data inputting means for inputting said wall-thickness data of said piping parts of said plant;
computer simulation means for simulating a change of a behavior of fluid which flows into an interior portion of said piping parts, execution means for performing pipe wall-thickness thinning prediction processing for said piping parts of said plant according to said simulated change of behavior of said fluid; and
outputting means for outputting results calculated by said execution means. - View Dependent Claims (7, 8, 9)
