PureEM™ for Concrete Pressure Pipe

PureEM™ is an electromagnetic (EM) inspection technology for evaluating the current condition of Prestressed Concrete Cylinder Pipe (PCCP), Prestressed Concrete Pipe (PCP), Reinforced Concrete Cylinder Pipe (RCCP), and Reinforced Concrete Pipe (RCP).

In Concrete Pressure Pipe (CPP), the high-tension steel prestressing wires are the main structural component. As these wires begin to deteriorate and break, specific pipe sections become weaker and more likely to fail catastrophically. PureEM for CPP can effectively locate and quantify the amount ofbroken prestressing wires in large-diameter pipe.

By identifying distressed pipe sections and specifying the number of broken wire wraps in a given pipe, PureEM provides owners of CPP with vital knowledge for implementing maintenance, repair and replacement programs.

PureEM can be deployed on any of Pure’s suite of inspection platforms, including PipeDiver® technology, PureRobotics™ and manned inspection tools. Post-inspection, qualitative results are provided to the utilities, allowing the repair of highly damaged pipes in a shorter period of time.

Inspection Benefits

  • Offers a method of determining deterioration in pipe sections.
  • Can be deployed on a variety of platforms to meet operational requirements.
  • Locates and quantifies the amount of broken wire wraps in pipe section.
  • Allows utilities to create prioritized pipeline repair, replacement and monitoring programs.
