Pressure vessels, refers to contain gas or liquid, carrying some pressure on the enclosed equipment, the extent of provisions for a maximum working pressure greater than or equal to 0.1 MPa (gauge), and the pressure and the product of more than cellar or the equivalent of 2.5 MPa.L gas, liquefied petroleum gas and maximum working temperature is higher than or equal to the boiling point of liquid standard fixed containers and mobile containers; costumes nominal working pressure greater than or equal to 0.2 MPa (gauge), and the pressure and volume greater than or equal to the product of 1.0MPa.L gas, liquefied petroleum gas and standards equivalent to or lower than the boiling point of liquid cylinder 60 degrees Celsius; chamber, etc..
The pressure vessel, is refers to the splendid attire gas or the liquid, the load bearing certain pressure sealed--n unit, its scope stipulated that is bigger than or is equal to 0.1MPa for the highest working pressure (super atmospheric pressure), and the pressure and the cellar product is bigger than or was equal to that 2.5MPa.L the gas, the liquefying gas and the highest operating temperature is higher than or is equal to the standard boiling point the liquid stationary vessel and the mobile vessel; The splendid attire nominal working pressure is bigger than or is equal to 0.2MPa (super atmospheric pressure), and the pressure and the volume product is bigger than or was equal to that 1.0MPa.L the gas, the liquefying gas and the standard boiling point are equal to or are lower than 60 degrees Celsius liquids the air bottles; Oxygen cabin and so on.
