Corrosion is an inherent risk of every fire sprinkler system, regardless of its age. Sprinkler system piping is susceptible to natural forms of corrosion as it is comprised of unprotected metal interacting with oxygen and water or moisture. Microbiologically influenced corrosion, or MIC, is an electrochemical process that involves bacteria which can accelerate corrosive conditions in fire sprinkler systems. If left untreated, corrosion can ultimately erode the lining of steel pipe, causing leaks to develop. Not only do leaks comprise the integrity of your fire sprinkler system, they also are disruptive, costly to repair and can potentially cause damage to your property.

Experts in implementing proactive corrosion solutions, Fireguard helps facilities all over the Mid-Atlantic region protect their systems from the damaging effects of corrosion.

5-year Inspections

NFPA standards require comprehensive inspections of piping systems every five years. This includes an inspection of internal valves and piping for obstructions. The obstruction inspection can show signs of MIC, which, if not caught early, can cause enough damage to require complete replacement of the system’s pipes. The internal inspection of valves includes opening the valves to inspect their strainers, filters and restriction orifices for visible evidence of blockage.

Scheduling a 5-year Inspection of your system is required by NFPA-25 standards. Fireguard can conduct a 5-year Inspection to keep you facility in compliance with code and save you money in the long term by catching signs of blockage or corrosion early.
