What type of material cushion should be used when installing a new bottom plate over an existing one?

• A. Drainage
• B. Compacted
• C. Non-conductive
• D. Non-corrosive

Answer: (D)

When installing a new bottom plate over an existing one, it is crucial to use a material cushion that is non-corrosive. This is important because the bottom plate of an aboveground storage tank is typically exposed to various environmental factors and substances that can lead to corrosion if inappropriate materials are used. A non-corrosive cushion will help to ensure that neither the new bottom plate nor the existing one will degrade due to chemical reactions or physical wear. The use of materials that are non-corrosive protects both the structural integrity of the tank and prevents contaminants from leaching into the stored substances, thus maintaining safety and compliance with regulatory standards. Selecting non-corrosive materials also contributes to the longevity of the tank and reduces the need for premature maintenance or replacement. In contrast, while drainage, compacted, and non-conductive materials may have their specific uses in tank installation or maintenance, they do not directly address the corrosion risk associated with the cushioning material between two plates. Thus, they do not provide the same level of protection that a non-corrosive cushion would offer in this context.
