Definition of pressure vessels

Thread Content

We need to design a container with a pressure of 0.75 MPa, internal dimensions of 1.8 meters * 0.8 meters * 1 meter, and a volume of 1.44 cubic meters. According to the \"Catalogue of Special Equipment\", a pressure vessel is a sealed device used to hold gases or liquids and withstand certain pressures; it is defined as a fixed or mobile vessel whose maximum working pressure is greater than or equal to 0.1 MPa (gauge pressure) for gases and liquefied gases, and whose maximum working temperature is greater than or equal to its standard boiling point, with a volume of 30 L or more and an inner diameter (for non-circular cross-sections, this refers to the largest geometric dimension of the cross-section) of 150 mm or more; Gas cylinders, liquefied gas cylinders, and cylinders for liquids with a standard boiling point of 60°C or lower, whose nominal working pressure at full charge is greater than or equal to 0.2 MPa (gauge pressure), and whose product of pressure and volume is greater than or equal to 1.0 MPa•L ; Oxygen chamber. Does my gas fall under the category of \"gases whose product of pressure and volume is greater than or equal to 1.0 MPa•L\"? Is this the latest regulation?

It belongs to the category of pressure vessels, but why isn’t it designed in a cylindrical shape?

Isn’t it easy to calculate whether the product of pressure and volume is greater than or equal to 1.0 MPa•L?

If the pressure is 0.1 MPa, then for 30 L it would be 0.1*30=3 MPa*L, right?

This refers to gas cylinders. Pressure vessels do not have this requirement...

Containers to be inspected. It is best to design it as circular, as it has a low cost.

Based on the provided information and the \"Regulations on Safety Inspection of Gas Cylinders,\" this container is rectangular in shape, and therefore it should not be designed, manufactured, or used as a \"gas cylinder\" as listed in the catalog of special equipment. If it is used in a fixed location, it is considered a \"fixed (pressure) vessel\"; otherwise, it should be a \"mobile (pressure) vessel\". For reference

It refers to gas cylinders. Pressure vessels are the first three conditions. Is this a rectangular device? It will be difficult to design.
