What Is Microbiologically Influenced Corrosion (MIC)?

Microbiologically Influenced Corrosion (MIC) occurs when microorganisms contribute to corrosion processes affecting metal surfaces and industrial infrastructure.

Although corrosion can occur from chemical or physical causes, microbial activity can significantly accelerate deterioration.

MIC may affect:

Pipelines
Cooling water systems
Boiler systems
Storage tanks
Heat exchangers
Process equipment
Water distribution systems
Industrial infrastructure

Results help organizations understand whether microbial activity may be contributing to corrosion problems.
