Reliability Analysis of Pipe Wall Thinning based on Quantification of Ultrasonic Testing
Research and Review Journal of Nondestructive Testing, 2023 Piping in nuclear power plants is subject to corrosion and erosion caused by the interaction with fluids it carries. In order to prevent accidents such as pipe rupture, it is necessary to non-destructively inspect the thickness of the pipe wall and ...
