It contains barite powder and the density is about 2.4. During operation, first raise the pressure in the tank to 0.2MPa (during which the air supply is uninterrupted), then open the ash discharge valve to carry out ash discharge operations. According to the definition of pressure vessel, it should not be classified as a pressure vessel. However, because there is a period of solid-gas mixing during work, and the pressure of the tank is about 0.2MPa. The user requires proof that it is not a pressure vessel. How to prove it? Please give your answers. attached: According to the definition of pressure vessels in the latest Special Equipment Catalog (2015), equipment that meets the following conditions of use is called a pressure vessel: 1. Container. Refers to a container that holds gas or liquid that carries a certain pressure. The specific situation is divided into the following two types: a) Fixed or mobile containers of gases and liquefied gases with a maximum working pressure greater than or equal to 0.1MPa (gauge pressure) ; b) Liquids with a maximum working temperature higher than or equal to the standard boiling point, fixed containers and mobile containers with a volume greater than or equal to 30L and an inner diameter (non-circular cross-section refers to the maximum geometric size of the inner boundary of the cross-section) greater than or equal to 150mm. 2. Gas cylinder. According to the performance of the holding medium, it is divided into two types:: a) Cylinders containing gases and liquefied gases whose nominal working pressure is greater than or equal to 0.2MPa (gauge pressure), and the product of pressure and volume is greater than or equal to 1.0MPa·L ; b) Liquid gas cylinders with standard boiling point equal to or lower than 60℃. 3.Oxygen chamber.
Why doesn't it belong? Of those three, which one is the one you mentioned?
According to the definition of pressure vessel, which one does it not meet? It is judged not to be a pressure vessel.
It must be a pressure vessel. The inlet and outlet of materials are not completed instantly, and a certain pressure needs to be maintained for a long time.
I have made dozens of sets before, and there is no objection that they are pressure vessels!
Why is it a pressure vessel? Could you please give me a detailed explanation.
Meet three conditions for pressure vessels
When the container is working normally, the pressure of the compressed air exceeds 0.1, let alone the volume, so it must be managed as a pressure container.
It must be a pressure vessel if it meets the three conditions of a pressure vessel. What we often do is managed by pressure vessels.
