What is Microbiologically Influenced Corrosion (MIC)?

MIC accounts for less than 5% of leaks in fire sprinkler systems.

Bacteria are always present in fire sprinkler piping. If you look for bacteria in fire sprinkler systems, you will ALWAYS find them. They are introduced to the fire sprinkler systems during the initial installation of the piping and they flourish in the warm confines of the fire sprinkler system.

Some bacteria do participate in the process of accelerating the corrosion of steel. However, in fire sprinkler systems Microbiologically Influenced Corrosion accounts for less than 5% of the leaks that occur. Oxygen-related corrosion accounts for 95% of the leaks that occur.

Read our white paper for more information: MIC is NOT the primary cause of corrosion in fire sprinkler systems.
