Corrosion Testing for Hot Dry Rock Geothermal Wells in Soultz-sous Forêts-Preliminary Results |
|
|
Corrosion risk for some materials proposed for Soultz
project at 200°C was evaluated for different steels with
and without protective coating. The preliminary
experiments were performed at autoclave which could
house specimen of various geometries and which
allowed electrochemical measurements. In some cases
the testing was performed using a corrosion
inhibitor. For uncoated steels the corrosion tests
showed erosion at 2 mm/y at 200°C. The corrosion
products formed on the surface did not provide any
corrosion protection. All the tested coatings performed
very well. They effectively reduced the corrosion and
they did not deteriorate during the test.
The chosen inhibitor did not give any significant inhibitor
effect.
