Ccase histories of four fire protection systems where corrosion resulted in premature discharge/leakage causing significant property damage or facilities downtime. Tuberculation of galvanized piping. Two cases of dealloying (dezincification) corrosion of brass sprinkler heads. Microbiologically induced corrosion (MIC) corrosion.
Field observations and laboratory test results for several different fire sprinkler failure investigations conducted in the past several years in a variety of locations across the US. Field experience with assessment data, basis for diagnosis, mitigation and rehabilitation recommendations to prevent recurrence are presented.
