HSDM Development Observation of Corrosion in Brine
© Baker Hughes Incorporated. All Rights Reserved. | 5
HSDM I - Low Corrosion rate
<1 mg/cm2/hr
HSDM II- High corrosion rate
<300 mg/cm2/hr
Corrosion in Brine occurs at the grain boundaries.
Corrosion in Acid occurs at the boundaries and the grain itself.
