Pressure vessel refers to holding gas or liquid, carrying a certain pressure airtight device.And chemical machinery, is in the process of chemical industry production and manufacturing, the use of all machinery and equipment, such as chemical machinery, chemical equipment, chemical components and so on all belongs to the chemical machinery.
Good, the so-called container, it is a closed device, and pressure vessel, is carrying certain pressure airtight device, the device of the pressure, can from liquid, can also come from the pressure of the gas. And chemical machinery, is in the process of chemical industry production and manufacturing, the use of all machinery and equipment, such as chemical machinery, chemical equipment, chemical components and so on all belongs to the chemical machinery.
Chemical machinery is greater than the limits of the scope of the pressure vessel and, because of the pressure vessel equipment commonly used in the petroleum chemical industry, energy industry, scientific research and military industry and other industries, so most of the pressure vessel is belong to the scope of chemical machinery. However, whether all the pressure vessel are chemical machinery, let us analysis the, want to think about this question, first of all we need to know accurate definition of chemical machinery: chemical machinery is used in the production of chemical industry machinery and equipment. In the chemical production in order to raw materials processed into certain specifications of the finished product, often takes raw material pretreatment, chemical reaction and separation of reaction products and refined a series of chemical process, implement these processes used in machinery, are often classified as chemical machinery. Ok, we can learn from the definition of the above chemical machinery, chemical raw material pretreatment, reaction, separation of reactants and refined a series of related equipment, chemical equipment.
