Typical Type of Systems installed

• Double interlock pre-action systems or “Dry” systems due to moisture critical area not wanting water sitting above equipment

Types of Corrosion Witnessed

• Internal Corrosion caused by electro-chemical reaction or moisture located in “sagging” pipe areas

Why testing for corrosion is important

• Corrosion inside the piping is undetectable with naked eye which can cause pipe failure during an “event” which could cause areas of the facility not “activated” to have water damage.

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