Pressure Vessels of Various Pressure

The concept of pressure vessels of various pressure

1, the working pressure: in normal operating conditions, the container at the top of the highest possible pressure. That is "content regulation" in the title of the maximum working pressure.
2, pressure vessel the maximum allowable working pressure: refers to the design temperature, thecontainer at the top of the table are the maximum allowed under the pressure. Thepressure vessel is based on the calculated effective thickness of the shell, and take the minimum.
3, nominal pressure: a pressure by the normalized value, that value by a large number of pressure levels grouped into a certain number of series, the series known as thenominal value of the pressure. Nominal pressure to PN said.
4, the design pressure vessel: refers to the top of the container set the maximum pressure,working pressure of not less than its value. Equipped with a safety relief devicepressure vessel, the design pressure of not less than the safety valve opening pressure or bursting disc burst pressure.
5, calculated pressure vessel: refers to the corresponding design temperatures, to determine the thickness of the pressure components, including liquid column static pressure.
Description: pressure vessel The design pressure of the working pressure is set based on the originalvessel design pressure is not the pressure of work. Working pressure is required by the process operating conditions, design pressure is the design temperaturetogether with the corresponding design of a container load conditions.
