Overview
Flow-accelerated corrosion (FAC) Erosion - corrosion of carbon steel piping internals is an insidious, persistent and widespread problem in feedwater systems and steam generator circuits in conventional fossil fuel and nuclear power plants (NPPs). These processes lead to reduction in wall thickness and risk of loss of containment, hence posing a major safety concern for personnel and plant operation.
Our system monitors pipe wall thickness with a wireless connection, allowing you to gauge the effects of corrision.
How does it work?
The system consists of a novel magnetic flux leakage sensor. It can be permanently installed in areas of expected erosion/corrosion. Thickness measurements are then transmitted wirelessly and can be read with a mobile phone app.
As long as the electronics are shielded, the system can operate in temperatures up to 500° C. It is targeted at piping in locations that contain areas susceptible to wall thinning (e.g. at pipe bends) with restricted access (i.e. physical impediments or health and safety constraints) where conventional wall thickness inspection by ultrasonic thickness gauges is not feasible.
It can also run on energy harvested from its location, negating the need for running electrical wires.
