Typical Type of Systems installed

• “Wet” systems within the building

• “Dry” systems may be installed in moisture critical areas

Types of Corrosion Witnessed

• External Corrosion caused by airborne factors created during manufacturing or industrial processes

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

Why testing for corrosion is important

• Fumes or processes performed could cause expedited corrosion concerns reducing lifecycle of the installed system

• Protection of process/manufacturing equipment due to leaks caused by undetected corrosion or equipment loss due to fire during an “event” and sprinkler system failure

• Personnel protection during an “event” in which sprinkler system needs to activate but fails to do so properly due to undetected system deficiency

• Loss of valuable production time due to equipment or process area downtime due to leaking pipe or failure of system during an “event” caused by undetected corrosion.

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

• UT could be implemented as part of the facility “Turn Down” process to stay ahead of costly and untimely repairs.
