A pressure vessel is a pressurized container that can withstand pressure
Apr 13, 2018

A pressure vessel is a pressurized container that can withstand pressure. Pressure vessels are extremely versatile and have important roles and roles in many sectors, such as industry, civil and military, and in many areas of scientific research. The pressure vessels used in the chemical industry and the petrochemical industry, which are used only in the petrochemical industry, account for about 50% of the total pressure vessels. The pressure vessel is used in chemical and petrochemical industry, mainly for heat transfer, mass transfer, reaction and other technological processes, as well as storage and transportation of pressurized gas or liquefied gases. There are also extensive applications in other industrial and civil fields, such as air compressors. All kinds of auxiliary machines (coolers, buffers, oil and water separators, storage tanks, evaporators, liquid refrigerants, etc.) are all pressure vessels.

Pressure vessel: pressure vessel is a sealed device that carries a certain amount of pressure. In order to more effectively implement scientific management and safety inspection, "pressure vessel safety supervision regulations" of our country according to the working pressure, medium hazard and its role in the production of pressure vessel can be divided into three categories.

Different requirements for the design, manufacturing process, and inspection items, contents and methods of pressure vessels of each category are made. The pressure vessel has implemented the import safety quality license system, and the goods that have not obtained the import safety quality license certificate are not allowed to be imported. Should be in accordance with the latest TSG21-2016 "stationary pressure vessels safety technology supervision regulation in the division, according to the first medium is divided into the first group of medium and a second group of medium, and then according to the pressure and volume category Ⅰ class, Ⅱ class, Ⅲ classes, old let rules called the first, second, third class is no longer applicable.
