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.
