Typical Type of Systems installed

• “Dry” Systems in Northern and Cold Climates

• Either “Wet” or “Dry” in more temperate climates

Types of Corrosion Witnessed

• External Corrosion caused by road salt or and other airborne factors

• Internal Corrosion caused by trapped moisture located in “sagging” areas specifically in “dry” Systems. Wet systems may see electro-chemical corrosion and/or a buildup of sludge causing MIC deterioration

Why testing for corrosion is important

• Facility downtime due to system failure during an “event” caused by undetected corrosion.

• Loss of property or persons due to system failure during an “event” caused by undetected corrosion.

• Overall system integrity verified instead of assumed during standard testing procedures.

• Lifecycle of piping can be severely reduced due to airborne contaminants, unable to assume useful life is valid
