PipeDiver® Condition Assessment The PipeDiver® tool is an innovative, free-swimming condition assessment platform for water and wastewater pipelines that operates while a main remains in service. The PipeDiver platform is ideal for critical large-diameter pipelines that cannot be removed from service due to lack of redundancy or operational constraints. It can be effectively deployed for long inspections on several types of pipe to determine baseline condition. On concrete pressure pipe, the tool can identify and locate broken prestressing wire wraps, which are the main indication that this type of pipe will eventually fail. For metallic pipes that utilize a steel cylinder as the main structural component, the tool can locate and detect broad areas of cylinder corrosion. When inserted into a live pipeline through a hot tap connection, an existing access or a submerged tank, the tool travels with the product flow and is able to navigate most butterfly valves and bends in the pipeline.
