(1) high-pressure vessels;
(2) medium-pressure vessels (only the degree of toxicity for the extreme and highly hazardous media);
(3) medium-pressure storage containers (only the degree of flammability or toxicity for the medium hazards of the media, and the pV multiplier is greater than or equal to
10 MPa-m3); (Note 2)
(4) medium-pressure reaction vessels (only the degree of flammability or toxicity for the medium hazards of media, and pV multiplication greater than or equal to
(4) medium pressure pressure containers (only the degree of toxicity for the medium hazardous media) ) medium-pressure reaction vessel (only flammable or toxicity degree of medium hazardous media, and pV product is greater than or equal to
0.5 MPa-m3);
(5) low-pressure vessel (only toxicity degree of extreme and high hazardous media, and pV product is greater than or equal to
0.2 MPa-m3);
(6) high-pressure, medium-pressure shell and tube type Waste heat boilers; (Note 4)
(7) Medium-pressure glass-lined pressure vessels;
(8) Pressure vessels made of materials with a high strength level (meaning that the lower limit of the specified value of the tensile strength in the corresponding standard is greater than or equal to 540 MPa)
;
(9) Mobile pressure vessels, including railroad tankers (the medium of which is liquefied gas, cryogenic liquids) , tank cars
[liquefied gas transportation (semi-trailer) cars, cryogenic liquid transportation (semi-trailer) cars, permanent gas transportation (semi-trailer) cars] and tank
type containers (medium for liquefied gases, cryogenic liquids), etc.;
(10) Spherical tanks (volume greater than or equal to 50 m3);
(11) cryogenic liquids storage containers (volume greater than or equal to 5 m3).
2. One of the following cases, for the second category of pressure vessels (except for the provisions of paragraph 1 of this article):
(1) medium-pressure vessels;
(2) low-pressure containers (toxicity level for the extreme and highly hazardous media);
(3) low-pressure reaction vessels and low-pressure storage containers (flammable media or toxicity level of medium hazardous media)
(3) low-pressure reaction vessels and low-pressure storage containers (flammable media or toxicity level of moderate hazardous media)
(4) low-pressure containers (toxicity level of medium hazardous media).
Mass);
(4) low-pressure shell-and-tube waste heat pots and pans;
(5) low-pressure glass-lined pressure vessels.
3. Low-pressure vessels for the first category of pressure vessels (except for paragraph 1, paragraph 2 of this article)
Transferred from the pressure vessel safety and technical supervision regulations, and therefore there is no strict classification.
