Reference number : GC-2017-Q2-04364, amendment number : , agreement type : G, recipient legal name : Xu, Yuan (Ryerson University), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Engage Grants for Universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : Pure Technologies is a world leader in the development and application of innovative technologies for_x000D_
inspection, monitoring and management of critical infrastructure. Non-destructive testing (NDT), such as_x000D_
ultrasound techniques, can be used to estimate the wall thickness for identifying the specific areas along a_x000D_
pipeline that requires the immediate renewal. Compared to other conventional NDTs, ultrasound techniques_x000D_
have accurate location detection, high sensitivity and efficiency, and low cost. It has received a significant_x000D_
attention from the industrial point of view. The signal received by the conventional ultrasound thickness_x000D_
measurement device contains abundant information such as that related to the corrosion either on the coating or_x000D_
on the surface of the metal pipe ._x000D_
A key issue of measuring wall thickness with ultrasound is that the cement coating around the pipeline affects_x000D_
the accuracy of the measurement. If the distance between reflected signals is shorter than half of the spatial_x000D_
span of the incident pulse, the echoes from various interfaces might overlap. It is often difficult to distinguish_x000D_
the signals due to the coating from those due to the wall. The goal of this project is to develop an advanced_x000D_
ultrasound thickness measurement system integrating with effective signal processing methods for identifying_x000D_
the reflected signals of interest to accurately assess the pipe wall. We will also assess if an ultrasound array_x000D_
system can improve the detectability of the coating layer., program purpose french : Pure Technologies is a world leader in the development and application of innovative technologies for_x000D_
