A small question regarding the catalog of special equipment
Thread Content
The definition of pressure vessels in the catalog of special equipment states: \"Cylinders used to contain gases, liquefied gases, and liquids with a standard boiling point of 0°C or lower, where the nominal working pressure is 0.2 MPa (gauge pressure) or higher, and the product of pressure and volume is 1.0 MPa•L or higher.\"； ”What does the pressure referred to as the \"product of pressure and volume\" for this gas cylinder mean? Is it the design pressure? Work stress? Is there any official documentation outlining this? I hope those with more experience can share their insights. Thank you all
“\"Nominal working pressure greater than or equal to 0.2 MPa for full-pressure equipment\" refers to the working pressure.
It refers to the \"nominal working pressure\".....
The previous sentence mentions it: nominal operating pressure
OP, the answer is in the question itself: the nominal working pressure of the pressure vessel is greater than or equal to 0.2 MPa (gauge pressure)
It can also be called “filling pressure” when used on gas cylinders.
