Corrosion Testing
Corrosion studies in chemical plants and cross country pipelines and evaluate stability of
structures. In-site metallographic technique is also used independently to evaluate various
types of corrosion in equipment and components working under severe conditions.
Evaluation of pitting, crevice corrosion, corrosion fatigue, sensitization and stress
corrosion cracking in boiling MgCl2 or CaCl2 incorporates
qualitative as well as quantitative features.
