Implementing phase array ultrasonic testing on a water pipeline inspection gauge

供水网络代表着世界各地数百万公里的老化管道。这些管道通常埋在地下，并不断受到腐蚀、地面移动和挖掘工程的影响。绝大多数管道是由铸铁制成的，并且是在上个世纪建造的。Pure Technologies是一家加拿大公司，开发了PipeDiver，这是一种管道检测仪（PIG），用于在线检测泄漏和管道壁厚测量。Pure Technologies将与巴黎高等技术学院合作开展一项为期三年的研究计划，以开发下一代在线管道检测仪。该项目的目的是将超声相控阵成像技术添加到PipeDiver中，以检测大直径铸铁管道的轴向裂纹。

Water supply networks represent millions of kilometres of aging pipelines around the world. Those pipelines are typically buried and are continuously exposed to corrosion, ground movements and excavation works. The vast majority of the pipelines are made of cast iron and were built during the last century. Pure Technologies, a Canadian company, developed PipeDiver, a pipeline inspection gauge (PIG) for in-line detection of leaks and pipe wall thickness measurements. Pure Technologies will collaborate with École de technologie supérieure on a three-year research program to develop the next generation of in-line pipe inspection gauge. The aim of the project is to add ultrasonic phased array imaging technology to PipeDiver so as to detect axial cracks in large diameter cast-iron pipes.
