As for application, while floating roof tanks can hold most liquids, they are primarily used in the petroleum industry. Horizontal storage tanks can be installed underground or above ground and are used in a variety of industries for the storage of light and heavy petroleum products, chemical solutions, water, food products, and other liquid products.
If intended for underground storage, horizontal steel tanks are given a number of coatings and insulations to prevent corrosion. These robust fuel tanks are impervious to nearly all disasters, making them ideal for military or remote fuel facilities. Pressure vessels are used across most industries and store a variety of products, including petroleum products, liquified gasses, and water.
Vessels are built in accordance with the ASME Boiler and Pressure Vessel Code, which regulates pressure vessel design, fabrication, materials, testing, and certification. Pressurized storage vessels come in many shapes, but the most common shape is a cylinder with end caps heads. The shape of the vessel and the end caps are designed to meet the requirements of the product being stored.

If you are looking for an industrial storage tank, then there are certain things you may consider before buying it in order to fulfill your business requirements.
One of the most important things that you need to look at is the purpose of the storage tank. Actually, storage tanks come in different shapes and sizes. These storage tanks are made of different materials which includes polythene, fiberglass, and steel. Some of the tanks are used to store oil, some are used for chemicals, water, and gases. Make it sure to buy your industrial storage tanks from a reputed company. You might have been thinking that what storage tanks are. From the very name it is clear that the storage tanks are used to store gases, liquids or other inflammable items.
Gross capacities can range from bbl to over 1. Corresponding tank sizes range from approximately 10 ft in diameter to over ft in diameter for some of the largest floating-roof tanks ever constructed. The photograph was taken during construction and shows the single deck, pontoon-style external floating roof. The type of construction selected for a storage tank depends on the size of tank required and might be dependent on the type of product being stored, the location and space available for storage, prevailing weather or site-specific conditions, and local safety or environmental considerations.
Although the earliest storage tanks used by the petroleum industry were constructed from various types of wood, we will concern ourselves with tanks fabricated from steel or optional nonmetallic materials.
Before the development and perfection of welding processes, petroleum storage tanks used either bolted or riveted construction techniques. The tanks would be designed and supplied as segmental elements for final assembly on site. Riveted tanks dating back to the early s can still be found around the world—many still in service. It is safe to say, however, that recurring maintenance costs and increased environmental and safety concerns dictate that older riveted tanks be replaced with new, state-of-the-art storage tanks.
However, bolted tanks are still used, especially in the smaller sizes typical of produced liquid storage. Current suppliers of bolted tanks can provide capacities up to 40, bbl or more depending on the storage application. Generally, bolted tanks are fabricated either from or gauge steel or several nonmetallic materials. If not galvanized or furnished with a protective coating for corrosion protection, bolted steel construction might not have the expected service life provided by welded-steel tanks.
Welded-steel tanks are constructed of thicker plate materials that can be designed to provide some corrosion allowance. One alternative to bolted construction is the shop welded storage tank.
The size and capacities of this type of tank are limited primarily by the method of transportation used to transfer the shop built tank to the final production site. The eleventh edition of API Spec. Table 1 presents a partial listing of the standard sizes specified in API Spec. In this table, "working capacity" refers to the maximum amount of oil that can be stored between the oil outlet and the overflow connection.
Shop-welded storage tanks provide the production industry with tanks of adequate safety and reasonable economy for use in the storage of crude petroleum and other liquids commonly handled by the production segment of the industry. A shop-fabricated tank is tested for leaks in the shop, so it is ready for use once it arrives on site. Tanks are transferred from the truck to the final location on site; completed piping connections and the tank is then ready to be brought on line.
A second alternative for bolted construction is the shop fabricated or field assembled nonmetallic storage tank.
