The 100,000 square foot data center was originally built and opened in 2002 with double interlock preacon fire sprinkler systems to protect the data halls. Galvanized steel piping was used for all of the preacon fire sprinkler systems. AŌer 8 years of service leaks began to develop in the 3” galvanized schedule 10 main piping. All of the leaks occurred within the main line piping under accumulaons of trapped water. The metal loss was characterized by highly localized aƩack with many deep singular round boƩomed pits beneath the trapped pools of water.Based on the history of leaks occurring in the facility, Engineered Corrosion Solutions was contracted to identify the root cause of the corrosion and develop a corrosion control strategy to prevent future leaks.
