Is the negative pressure vessel a pressure vessel?
Greater than -0.02 MPa is a pressure vessel designed and manufactured under gb150-1998 rules but is not regulated by the rules
Don't be misleading, as long as the containers designed by GB150 belong to the pressure vessel, the negative pressure vessel is not regulated by the container
Is defined in the special equipment safety supervision regulations, please refer to the pressure vessel, refers to holding gas or liquid, carrying a certain pressure airtight device, the range of maximum working pressure is greater than or equal to 0.1 MPa (table), and the product of the pressure and volume of greater than or equal to 2.5 MPa, L 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 0.2 MPa pressure (table), and the product of the pressure and volume greater than or equal to 1.0 MPa, L standard of gas, liquefied gas, and the boiling point is equal to or lower than 60 ℃ liquid cylinders; Oxygen tank, etc.
This problem has been discussed a lot of times on BBS, which is just a few of the concepts, the pressure vessel, the GB150 pressure vessel, the pressure vessel. The pressure vessel we commonly refer to is the pressure vessel that is referred to as the containment vessel of all the pressure media. Under the GB150 design, the pressure vessel created should be called the GB150 pressure vessel. The pressure vessel, which is governed by a tolerance, is called a tolerance pressure vessel. When you are discussing, you should take these questions first, so as not to say that you are wrong.
