Learn More About Oil Tanks

By Essie Craft


Oil tanks refer to the containers that are used for carrying refined petroleum liquid products. They can either be used for short terms storage reasons or long term storage reasons. This name can also be used in reference to the reservoirs for the same products.

These facilities are found near the refineries for the petrochemical products. Besides, they can also be found where the marine containers usually discharge their petroleum products. A number of them are also connected to the various pipelines. The pipelines do transmit the raw materials and can therefore be supplied by the means of the road as well as the rail transport.

The containers found next the depots have various exposures. Some are covered under ground and are known as underground containers. Others are left above the ground though they are covered so they are referred to as covered or aboveground vessels. They all serve the same role whether they are sheltered or not.

The containers are majorly used to keep both the crude plus refined petrochemical liquids. They may also be used for carrying the products. This therefore shows that the vessels are found and applied in the reservoirs and also during their transportation.

The containers operate under different mechanisms. Some operate without any pressure application in order to discharge the products. Others use little pressure for the same purpose. This therefore clearly distinguishes from other pressure containers. Furthermore, it makes them easy to use.

They are produced in several different forms. These forms are dictated by the producers. They might be rectangular, cylindrical, cone shaped, spherical and square. As much as the installation is considered, they might either be cylindrically or uprightly installed.

They are also available in different sizes. This is determined by the amount of the petrochemical product that each of them would store or carry. It might also be determined by the types of the trucks that would be carrying them during transportation.

A number of regulations are usually applied to regulate the manufacture, installation and the use of these containers. Most of these regulations are usually environmental. This helps in limiting any chances of releasing harmful gases or products to the environment.

They all need bunding. This refers to a containment dike surrounding the tank. It aids in preventing the leaking of the products into the environment.

Some bear floating roofs. Those roofs keep moving by the levels of liquids contained. This greatly helps in reducing space for vaporization for the liquid thus lowering environmental pollution.

The metal ones need thorough insulation. This is important because it prevents them from getting corroded. The main insulating technique usually used is cathodic protection.

Many substances are used to produce these containers. The commonest substances applied are steel as well as concrete. This is owing to their strength and also durability in resisting numerous stresses.

The cost of oil tanks vary from place to place. They are also readily available in the market. Therefore, they are containers which are really important in keeping such petrochemical products with limited risks of environmental pollution.
