Domed external floating roofing tanks: They are similar to the external floating roof tanks except that the roof is lighter in structure.They have a cylindrical shell made of steel on top which remains open and floats on the surface of the fluid stored inside the vessels. External floating roof tanks: Such tanks are designed to store crude oil and petroleum products safely in bulk quantities.Such tanks are specially designed to weather severe weather conditions likes lashing of the rain or the hazards of strong winds. Internal floating roof tanks: These tanks are equipped with floating roofs which in turn are covered with fixed roofs.

They are primarily used for storing water. Fixed-roof tanks: These are designed to have a cone or domed shaped roof permanently attached to its cylindrical shell.Let’s take a look at the different types of industrial aboveground storage tanks: Pump cut-off devices that prevent spilling of liquid by 95%.Digital computers, telepulse, discrete vision gauges that offer fast response to regulate the level of liquid in the tanks.Audible or code signals to communicate between container gauge and pumping station directly.Audible or visual high liquid level or surveillance station for constantly continuous monitoring of liquid flow in the vessels.They are also equipped with secondary containment vessel to prevent spilling and leakage of liquids.īuilt to counter corrosion, these tanks also come armed with overfill prevention mechanism to prevent releases and can identify leaks.Īdvanced storage aboveground tanks for industries are fabricated to prevent discharge of liquids with the following features: Modern units have huge storing capacities and can hold up to 30,000,000 gallons of industrial petroleum products safely. They’re placed on surface of the earth on stable platforms giving them the name and are usually made of stainless steel, fiberglass or polyethylene. 10 Aboveground Fuel Tank Electrical Requirements What are Above Ground Storage Tanks?Īboveground storage tanks are large vessels and containers used for storing water, chemicals, crude oil, gases, gasoline and petroleum products in bulk quantities.
