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.

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。绝大多数管道由铸铁制成，建于上个世纪。加拿大Pure Technologies公司开发了管道检测仪PipeDiver，用于在线检测泄漏和测量管壁厚度。Pure Technologies将与École de technology supsamrieure合作开展一项为期三年的研究计划，开发下一代在线管道检测仪表。本课题的目的是在PipeDiver中加入超声相控阵成像技术，以检测大直径铸铁管的轴向裂纹。
