Pressure vessel classification
Thread Content
The medium is the first group of media, with a working pressure of 9MPa and a design pressure of 9.9MPa. Because an air tightness test is required, the maximum allowable working pressure is 10.5MPa. Which category is this equipment classified into (Class II or Class III)?
Without volume, it is impossible to judge. Classification is determined by design pressure.
Classification according to design pressure.
Check the 5th floor diagram according to your own volume, which category should you look at?
According to the large capacity regulations, they are classified according to the design pressure. There is no need to consider the maximum allowable working pressure. They can be classified according to Figure A-1. No one can find faults.
The volume is greater than 30L, thank you for your answers.
Not only the container is larger than 30L, but also whether the inner diameter of the equipment is greater than or equal to 150mm. If it is larger, it will be classified according to the figure. If it is not larger, it will not fall under the jurisdiction of the regulations.
