Documented field corrosion performance of various titanium alloy materials exposed to geothermal wellhead brines and separated fluids is reviewed. Extensive laboratory testing in hot synthetic geothermal and natural brine media confirms titanium’s overall excellent suitability for geothermal brine service with respect to general, pitting, crevice, and stress corrosion. Recommendations and guidelines for successful, cost-effective applications, involving direct geothermal brine contact, are presented with emphasis on proper titanium alloy selection.
