Pressure vessels are quite dangerous and have occurred much accident in history of its department. That is why these are designed and operated by quality engineers and have involved parameters such as safe operating system and temperature.
Pressure vessels can be made from variety of materials and of any shapes. These shapes are spheres, cylinders, and cones that are usually employed. Mostly used design is cylinder with end caps called heads. These head shapes are frequently either hemispherical or torispherical. More complicated shapes have been much harder to analyze and are usually far more difficult to build.
Theoretically, a sphere could be best shape of pressure vessel. Unhappily spherical shape is tough to construct and more expensive that is the reason why cylindrical vessels are mostly used.
Now we talk about its material, pressure vessels are made of steel, concretes frail nature steel cabling is used to reinforce it. Same method is employed for other materials that are weak in tension.
Technically, any material with good tensile could be used. Codes and regulations are used to govern manufacture and operations so as to avoid potential loss of life and accidents.
Transportable containers are most commonly used. Steel pressure vessels are designed to perform dual purpose air storage as well as partial separation of moisture. Container should be free of any cracks and leakages, thereby ensuring complete safety to surrounding environment.
The safe design, operation, maintenance and installation with appropriate code and standard are compulsory for employee’s safety and health. So Pressure vessels are storage tanks that have been designed to held and maintained liquid and gases.
