Abstract
The present invention relates to a method of fumigating closed systems susceptible to microbially influenced corrosion (MIC). The method is particularly useful in a method for mitigating MIC in fire protection sprinkler systems.
Claims22
A method of fumigating a closed system susceptible to microbially influenced corrosion, said closed system comprising an inner surface and one or more openings providing for the introduction and elimination of fluids into said closed system, said method comprising evacuating said system under subatmospheric pressure and introducing an effective amount of a fumigant into said system through at least one of said one or more openings to expose only said inner surface to said fumigant for an effective time of exposure.
A method of fumigating a closed fire protection sprinkler system, said system comprising at least one inner surface and one or more openings providing for the introduction and elimination of fluids into said system, said method comprising evacuating said system under subatmospheric pressure and introducing an effective amount of a fumigant into said system through at least one of said one or more openings to expose said at least one surface to said fumigant for an effective time of exposure.
