Vertical Storage Tanks

Horizontal Storage Tanks

Horizontal Diked Tanks

Overview

Diked Tanks

These cylindrical aboveground tanks 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. Diked containments can either be open top or closed top construction. Each tank is sized with the appropriate normal and emergency vent openings as defined in the tank's standard of construction.

The primary containment aboveground storage tank is housed within a rectangular steel dike which contains the product should a spill, tank leak or rupture occur. Tanks are built to Underwriters Laboratories specification standard UL-142.

Horizontal 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.

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

Each tank is sized with the appropriate normal and emergency vent openings as defined in the tank's standard of construction. Horizontal tanks may be single or double wall construction. If the tank is a double wall configuration, then it has interstitial monitoring capabilities. Tanks may also be built with or without multiple compartments for multiple fuel storage. Tanks are built to Underwriters Laboratories specification standard UL-142.

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.
