Vertical Configurations: These are
steel atmospheric tanks intended for aboveground storage of
non-corrosive, stable, flammable, and combustible liquids
that have a specific gravity not exceeding that of water.
Maximum allowable working pressure is 0.5 psig as measured
from top of tank. Vertical tanks may be of single or double
wall construction. If the tank is a double wall
configuration, then it has interstitial monitoring
capabilities.
These tanks may also be built with or without multiple
compartments for multiple fuel storage. Tanks generally
have flat bottoms and conical roofs.
Special fabrication can incorporate dished tops, dished and
coned bottoms all supported on skirts or legs. Only new
materials are used in tank construction. Each tank is sized
with the appropriate normal and emergency vent openings as
defined in the tank’s standard of construction. Tanks are
built to Underwriters Laboratories specification standard
UL-142. For special applications, such as products that
have a larger specific gravity than water, Modern offers
American Petroleum Institute, API, designed tanks in the
API-620 or API-650 design configurations.
