A tank is a metal or non-metal structure in various dimensions that is used to store and transport various liquids and gases. Currently, polymer tanks have become popular and are widely used for storing water.
Industrial metal or steel tanks are also widely used for storing petroleum and petrochemical liquids and gases in our country.
Fixed roof tanks
The roof of this type of tank can be conical or dome-shaped and welded to the tank body
This type of tank is widely used in industries; because most products have low vapor pressure
and remain liquid at ambient temperature. Chemicals such as sodium hydroxide solutions, water, and hydrocarbons with low vapor pressure (such as diesel) are stored in this type of tank.
The selection of the diameter and height of these tanks depends on the required storage capacity and the amount of space available for installation.
In this type of tank, the tank roof floats on the liquid surface, and as the liquid surface rises and falls, the roof also moves, and the movement of the roof on the liquid surface prevents further evaporation of the liquid.
This type of tank is used for compounds that have a low flash point or high vapor pressure, such as gasoline. This type of tank is used in two forms: internal floating roof tanks and external floating roof tanks.
Spherical Tanks
Another type of tank is cylindrical tank. One of the most commonly used examples of cylindrical tanks is water tanks. Calculating the volume of these tanks is one of the most frequently asked questions for students. In the following, we will learn more about numerical calculations and the software that exists to facilitate the calculation of tank volumes:
One of the types of pressure vessels are spherical pressure vessels. As it is clear from the name of these tanks, they have a spherical appearance and are placed on the holder. Spherical tanks are mostly used to store gases. Keeping gases under pressure can turn these tanks into very dangerous bombs. For this reason, careful examination of these tanks during design and construction is of great importance. In the rest of this article, you will learn more about spherical tanks under pressure.
Stress analysis of pressure vessels is one of the requirements for the safety control of these vessels. Finite element methods have made it much easier for engineers to calculate the stress in these reservoirs. In the training course of static analysis of spherical tank under internal pressure and gravity force, you will learn about stress analysis of spherical tank under pressure in Abaqus software.
