1.
The classification of pressure vessels according to the category of pressure vessel, is divided into: Ⅰ class pressure vessel, Ⅱ class pressure vessel, Ⅲ class pressure vessel.
The category of the pressure vessel, according to the dielectric properties or harmful to the medium (
With medium degree of toxicity and explosive damage)
, the design pressure p (
Unit MPa)
And volume V (
Unit L)
Factors such as the division.
Pressure vessel category should be indicated on the general layout design of pressure vessels.
Belong to Ⅰ class pressure vessel are: non flammable or toxic medium low pressure container.
Belong to Ⅱ class pressure vessel are: medium pressure vessel;
Low pressure container: extreme and highly toxic medium low pressure vessel;
Flammable or moderate toxicity medium low pressure low storage containers and reaction containers;
Low pressure tube shell type waste heat boiler;
Low pressure glass lining container.
2.
According to the classification of the pressure piping pressure piping installation license categories and its level is divided into: long distance,
Oil and gas)
Pipeline: GA class pressure pipeline, divided into GA1, GA2 stage;
Utility piping: GB class pressure pipeline, divided into gas pipeline (
GB1 level)
, heat pipe (
GB2 level)
；
Industrial pipeline: GC class pressure pipeline, divided into GC1, GC2, GC3 level;
Power pipeline: GD type of pressure pipeline, divided into GD1, GD2 level.
