Basic classification method

The classification of pressure vessels should be based on the characteristics of the medium, and the classification diagram should be selected according to the following requirements, and then the coordinate points should be marked according to the design pressure p (unit MPa) and volume V (unit L) to determine the container category:

(1) For the first group of media, the classification of pressure vessels is shown in Figure A-1.

(2) For the second group of media, the classification of pressure vessels is shown in Figure A-2.
