What is a Pressure Tank?
Have you heard of a pressure tank? This contraption is a closed vessel that holds liquid chemicals. But the pressure inside a this tank is different from the pressure outside the tank. This is because the tank is created to manage and control the pressure inside the tank. Industries and private sectors use pressure tanks to store chemicals like water, chlorine, ammonia and LPG.
Handling pressure tanks can be dangerous. There were people who got involved in accidents while handling the development and operation of pressure tanks. So a person must be knowledgable about the science and mechanics of pressure tank technology before he or she can operate it. Safety precautions are in order.
A pressure tank can have many shapes. A vessel shaped like a cylinder is a common design. There are complicated designs. Some are shaped like sections of spheres and cones. Other designs are possible but they were harder to analyze and more complicated and more expensive to construct. A cylindrical pressure tank has twice the strength of a cylindrical pressure tank; however the spherical tank is more difficult and more expensive to manufacture. So most pressure tanks are shaped like a cylinder. It is easier to build and maintain than other shapes.
Steel is commonly used to construct a pressure tank. Parts would have to be wielded together to shape the pressure tank. There are also standards for vessels that are used in either low or high temperatures or in special cases. For example: If the pressure tank will be used where the carbon steel would be susceptible to corrosion, a corrosion resistant material should be used to prevent the corrosion. Some pressure tanks are made of composite materials. Some tanks include polymers.
Pressure tanks have build in safety features to prevent unnecessary leakage from happening. Safety valves are installed to ensure that the pressure inside the pressure tank does not except in operation. There are also leak before burst features. This feature guarantees that a crack in the vessel will grow through the wall, allowing the pressure to be reduced at a manageable speed.
What are its uses? Pressure tanks are used in a variety of applications in industrial and private sectors. Homes use pressure tanks to store water. Industrial factories use pressure tanks to store and observe different chemicals like ammonia, propane, butane, chlorine and LPG. The passenger cabin of airplanes are even based from technologies found on pressure tanks. There are many more uses. These are just some of the most common applications.
There are more to know about pressure tanks and the technology behind it. Given its real world applications, the pressure tank has become one of the most used tanks in various industries.
