Corrosion is a significant issue in pipelines and aboveground storage tanks used in a wide range of Canadian industry settings requiring heating/cooling and the transportation/storage of petrochemical products. This project is centered on the development of state-of-the-art guided wave ultrasound nondestructive testing (NDT) systems for detection of corrosion in pipes and above ground storage tank floors. Such systems will provide early warning of a lack of integrity in pipes and tank floors and prevent extensive delays in industrial processes.The ultrasonic guided wave (NDT) methods developed in the project will use electromagnetic acoustic transducers (EMAT) to generate shear horizontal waves within steel pipes and plates. The methods are envisioned to be rapid and low cost screening techniques which complement more traditional NDT approaches such as through thickness ultrasonic testing. The project will focus on coupled numerical/experimental studies of factors that affect wave generation and propagation within test specimens containing corrosion type defects. This will include identifying the underlying contributions from both Lorentz force and magnetostrictive transduction mechanisms. The understanding developed through these studies will be applied within the project to design EMAT based NDT system prototypes with high reproducibility and low signal-to-noise. A successful conclusion to the project will enable our industry partner, Labratoire d'essai Mequaltech Inc., to translate the findings into fully operational EMAT based ultrasonic guided wave NDT instruments and compete more successfully in the international market for non-destructive testing contracts. Additional benefits include the training of engineering students on the use of technical NDT equipment and software packages.

腐蚀是管道和地上储罐的重要问题，在需要加热/冷却的加拿大行业环境中，以及石化产品的运输/储存。该项目集中在最先进的引导波超声超声非破坏性测试（NDT）系统的开发中，以检测管道和地面储罐上方的腐蚀。这样的系统将提供预警，以预警管道和储罐地板缺乏完整性，并防止工业过程中的广泛延迟。在项目中开发的超声波引导波（NDT）方法将使用电磁声传感器（EMAT）在钢管中产生剪切水平波。这些方法被认为是快速和低成本的筛选技术，可以补充更多传统的NDT方法，例如通过厚度超声测试。该项目将集中于影响含有腐蚀类型缺陷的测试样品中波浪产生和传播的因素的数值/实验研究。这将包括识别洛伦兹力和磁引诱的转导机制的基本贡献。通过这些研究获得的理解将在项目中应用于设计基于EMAT的NDT系统原型，具有高可重现性和低信噪比。 该项目的成功结论将使我们的行业合作伙伴Labratoire d'Essai Mequaltech Inc.将发现转化为基于EMAT的完全运行的超声波指导Wave Wave Wave NDT工具，并在国际市场上更成功地竞争非毁灭性测试合同。其他好处包括培训工程专业的技术NDT设备和软件包的使用。
