Periodical measurement of pipe wall thickness for power plant is performed with manual UT during outage. Furthermore, periodical water level measurement is performed during plant operation by using UT sensor because there is a possibility that the gas-void in the piping may adversely affects the components. There is necessary to carry out the monitoring during plant operation in order to realize the improvement of those managements. However, the continuous monitoring during plant operation is difficult...

Continuous monitoring system using high-temperature thin-film UT sensor

As for periodical measurement of pipe wall thinning, several concerns are indicated, such as unstability of measurement position and contact condition, additional work for removal of insulating material and preparing scaffold, unstability on complex geometry and difficulty of continuous monitoring under plant operation. In order to solve these concerns, we developed thin-film UT sensor which has high-temperature durability and flexibility. Furthermore, we preliminary developed prototype linear phased-a...
