PIPE THINNING PREDICTION DEVICE AND METHOD

摘要

PROBLEM TO BE SOLVED: To provide a pipe thinning prediction device, prediction method, and a pipe thinning prediction program capable of predicting the thickness or the thinning state of a pipe simply with actually sufficient accuracy without requiring complicated heat transfer analysis.;SOLUTION: This device has a heater 4 for heating the pipe 2 in the state where a fluid 1 flows inside; a heater control means 6 for heating the pipe 2 partially or wholly up to at least the first set temperature exceeding the fluid 1 temperature by controlling the heater 4; a temperature sensor 5 for detecting the partial or whole temperature of the pipe 2; and a prediction means 8 for predicting the thinning state of the pipe 2, based on a partial or whole temperature change of the pipe 2 detected by the temperature sensor 5, when heating is finished after the pipe 2 reaches the the first set temperature partially or wholly, and the pipe is cooled by the fluid 1.;COPYRIGHT: (C)2007,JPO&INPIT
