Modern Tank
Modern Welding Company, is the largest underground and aboveground steel tank manufacturer in the United States.

Aboveground Vertical Tanks
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.

Aboveground Horizontal Tanks
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.

Tanks can be furnished with stationary support saddles, anti roll supports or structural skids. Only new steel materials are used in tank constructions.
