Solution

Safe Life Extension

Gilles Lhuillier — Boilerwork section, preparator on the Dampierre site

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.

Customer needs
