In order to generally container (
Atmospheric pressure container)
Phase difference, only the container at the same time satisfy the following three conditions, is called: (pressure vessels
1)
Pressure of work,
Note 1)
Greater than or equal to 0.
1Mpa(
Work pressure refers to the pressure vessels under normal working condition, the top can reach the highest pressure (
Gauge pressure)
)
;
(
Excluding hydrostatic pressure)
(
2)
Inside diameter (
Non circular cross section refers to its maximum size)
Greater than or equal to 0.
15m。
And the volume (
V)
Greater than or equal to 0.
025 cubic (
3)
Loading medium for gas, liquefied gas and highest working temperature is higher than or equal to its standard boiling point of the liquid.
The national standard: 'special equipment safety supervision regulations' (
Japan on March 11, 2003 Chinese people republic of China, the State Council makes the 373th)
Is the supreme law, regulations, other standards under the regulations, other standards of pressure vessel using range is the expression of corresponding standards.
Regulations about the definition of pressure vessels, pressure vessels, refers to holding gas or liquid, carrying a certain pressure airtight device, the scope for the maximum working pressure is greater than or equal to 0.
1MPa(
Gage pressure)
And the product of the pressure and volume is greater than or equal to 2.
5MPa•
L the gas, liquefied gas and the highest standard of working temperature is higher than or equal to the boiling point of the mobile and stationary containers of liquid container;
All nominal working pressure is greater than or equal to 0.
2MPa(
Gage pressure)
And the product of the pressure and volume is greater than or equal to 1.
0MPa•
L standard of gas, liquefied gas and the boiling point is equal to or lower than 60 ℃ liquid cylinders;
Oxygen tank, etc.
