ABSTRACT:
The present invention relates to the application of a coating to a pipeline, FPS (Fire Protection System) or to pipe stock from which a pipeline is fabricated. A composition which when applied to the inside surface of the pipe prevents either chemical corrosion or microbiologically influenced corrosion is disclosed. Also disclosed is a method for utilizing this material to protect both existing pipelines and the raw stock used to construct pipelines and various apparatus for applying a coating of the composition, cleaning, and maintenance of the passive coating. Also disclosed is a method to recycle the composition to be used in other industrial pacification processes. The composition, methods, and apparatus are environmentally friendly and eliminate the need to use poisonous, environmentally damaging biocides currently used in the prevention of microbiologically influenced corrosion (MIC) in FPS, water treatment, nuclear, petroleum and natural gas transportation pipelines, and various processing equipment within industry.
