Abstract: A system for protecting storage tank soil side bottoms against corrosion includes a pipe system comprising non-perforated inlet pipes and perforated pipes connected thereto. A sleeve container having solid VCI compounds therein is inserted into the perforated pipes. The sleeves are permeable to vapors emitted by the solid VCI compounds and flow through the pipe to a perforation where they are admitted into an area beneath a storage tank so that they can contact the tank bottom (soil side) and protect the same from corrosion.
