Tanks should be designed and restrained to prevent damage or loss of contents, depending on the design criterion being considered. Tanks should be restrained to prevent sliding and overturning failure, without relying on friction between the tank and support pads.

Differential movement between a pipe system and storage tank needs to be accommodated. The pipe should extend radially in a single continuous length from the tank for at least 15 pipe diameters before the first restraint, connection or abrupt change in direction.
