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. Alternatively, solid SCI compounds can be used in combination with VCI compounds. The corrosion protection system is designed to be used with aboveground storage tanks. This includes, but is not limited to, single bottom tanks: newly installed or existing tanks undergoing bottom replacement or installation of double bottoms. These tanks are located on substrates such as the compacted soil/sand or hard substrates such as concrete, bitumen mixtures and asphalt where channels can be cut into the substrate for installation of the pipe system.

Storage tank bottom corrosion protection system

A method and apparatus for the corrosion protection of tank soil side bottoms is achieved by providing equipment to an existing storage tank as by installing a chime delivery system about the perimeter of the storage tank bottom plate, and introducing an appropriate amount of a corrosion inhibitor into the chime delivery system, whereby the corrosion inhibitor is readily admitted into the spaces between the substrate and the tank bottom plate. The system avoids any refurbishment of the tank and allows for easy introduction and replenishment of inhibitor without interruption of tank operations. The system also does not require any renovation of the tank, and does not require any replacement of the tank bottom plate panels.
