Accoustic emission testing

Needs

Extension of service life, anticipating aging and optimizing maintenance of structures + Maximizing Profitability

Solution

Safe Life Extension

Gilles Lhuillier — Boilerwork section, preparator on the Dampierre site

This stainless steel pipe (diameter 160 mm) discharges cooling system waters, among other effluents. Thus, the pipe must be inspected on a regular basis in order to check for any leak into the environment before discharge into the Loire River. Approximately fifty sensors were installed along the pipe. After running tests, no leak were detected. Acoustic emission testing is flexible and accurate. This method resulted particularly safe and cost-saving, compared to the cost of a shutdown in case of leak.
