DSIR constructed a Mobile Corrosion Test Facility for short term corrosion monitoring trials at remote field sites. The facility was assembled to test the corrosivity of geothermal steam containing high levels of potentially corrosive gases, CO2, H2S and NH3. Commissioning experiments were conducted using geothermal steam derived from Broadlands well BR22 containing 2.5 percent by weight of gas in november/December 1984. Automated monitors were used to determine corrosion rates of carbon steel subjected to a range of simulated geothermal power station environments over short exposure periods. During the commissioning trials operational procedures were established for maintaining and monitoring the various test environments. The limitations of automated monitors were identified and the need for immediate, on-site assessment of corrosion results was also indicated. During these and subsequent trials a Slow Constant Extension Rate Machine was also proved capable of testing stainless steels for susceptibility to stress corrosion cracking. The commissioning results will allow a realistic comparison of the existing Broadlands database of materials results with those obtained from subsequent high gas trials. ABSTRACT. INTRODUCTION.
