Corrosion in Fire Sprinkler Systems: Increasing Your Liability, Increasing Your Costs, and Shortening System Life

Corrosion in Fire Sprinkler Systems: Increasing Your Liability, Increasing Your Costs, and Shortening System Life

A sprinkler system protects buildings, property and, most importantly, lives. But that same sprinkler system needs protection as well. Most sprinkler systems are made of steel piping, and when oxygen and water are trapped inside those pipes, corrosion will occur unless preventative measures are taken.
