Manage Corrosion to Extend
Your System's Life

Corrosion is a silent threat to fire sprinkler systems that's difficult to detect without an inconvenient inspection for building tenants. When left unmanaged, it can cause anything from a minor leak to serious danger for building occupants and property.

Water + Air + Metal = Corrosion

Fire sprinkler systems are the perfect environment for corrosion due to the presence of water, air, and metal. In a wet system, trapped air combines with the pipe and water already present. In dry systems, condensation pools inside the pipe and combines with the pressurized air there.

Preventing and monitoring corrosion allows you to extend your system's life and avoid the consequences of this silent threat.

Signs of Corrosion

in a Fire Sprinkler System

  • Visible corrosion at pipe joints
  • Pin-hole leaks
  • Increased water delivery times
  • Evidence of spot repairs
  • System impairment

Vent to Prevent Corrosion

Releasing trapped air in wet pipe sprinkler systems has been proven by the National Fire Prevention Association (NFPA) to help prevent corrosion. Since the 2016 edition of NFPA 13, air vents have been required on all wet systems.

PURGEnVENT automatic air vents include easy installation options for new or pre-existing systems. They continuously release trapped air while the system operates to prevent corrosion with no extra effort.

Monitor Corrosion to Stay Informed

Monitoring corrosion in both wet and dry systems gives you the time to properly plan and address it. If you know the pipe is corroding and the rate of corrosion before a costly leak or other dangerous damage occurs, you have time to plan to mitigate the corrosion or replace the system.

CORRinSITE corrosion monitors require now power and are compatible with both wet and dry fire sprinkler systems. The plug corrodes at the same rate as the system's piping. When it corrodes through, the indicator turns from white to fluorescent orange.

CORRinSITE's rate of corrosion tells you the system's corrosion rate. That gives you time to decide how to address the issue rather than an expensive leak or tragic system failure being the first indication.

Meet Code Requirements

NFPA has required air vents in wet pipe fire sprinkler systems since the 2016 edition of NFPA 13. Long-term studies proved that releasing trapped air from systems helped to prevent corrosion.

Jurisdictions across the country are adopting NFPA 13 (2016) and later editions. Even if your area doesn't require air vents currently, they're still an effective way to prevent corrosion.

New Trends in Corrosion
and Freeze Protection for Resilient
Fire Sprinkler Systems

Corrosion and freezing temperatures threaten the stability of wet and dry fire sprinkler systems in facilities around the world. Luckily, new innovations are bringing solutions like air vents and auxiliary drain accessories to the market. Many of these products are easy to retrofit onto existing systems, so the benefits are not limited to future systems. Although corrosion and freezing temperatures are nothing new, these innovations could bring a new chapter of simplified maintenance and increased reliability to wet and dry fire sprinkler systems.
