The pressure vessels are divided into three categories, which are applicable to the three types of pressure vessels
The Angle of understanding is biased, and the three categories are classified from the perspective of safety management, which is to say the extent of danger, the scope of application is from the technical point of view!
He's a new method of dividing the old tolerance rules.
Pressure vessels safety technology supervision regulation by both pressure and volume of container product size, and medium risk as well as the role of containers in the production process of comprehensive classification method, for safety and technical supervision and management. The method divides pressure vessels into three types: The third type of pressure vessel, with one of the following conditions, is the third type of pressure vessel: High pressure vessel; Medium pressure vessel (only toxic level is extreme and highly hazardous); Medium pressure storage containers (only inflammable or toxic to moderate hazard media, and the pV product is greater than or equal to 10MPa m3); The medium pressure reaction vessel (which is only moderately hazardous to the flammable or toxic level, and the pV product is greater than or equal to 0.5 Pa m3); Low pressure vessel (limited toxicity to extreme and highly hazardous medium, and the product is greater than or equal to 0.2 MPa m3);
