Pressure vessels belong to special equipment.
Special equipment, involving life safety, dangerous boilers, pressure vessels, pressure piping, elevators, cranes, passenger ropeways, large amusement rides and on-site special motor vehicles. Among them, boilers, pressure vessels, pressure piping for pressure class special equipment; elevators, lifting machinery, passenger ropeways, large amusement rides for electromechanical special equipment.
For each category of pressure vessels in the design, manufacturing process, as well as the inspection program, content and mode made different provisions. Pressure vessels have been implemented in the import of goods safety and quality licensing system, without obtaining import safety and quality license certificate of goods are not allowed to import. Pressure vessels are extremely wide range of uses, it is in industry, civil, military and many other sectors as well as many areas of scientific research have an important position and role.
Expanded information:
Specialty equipment because of its specificity and danger, should be strictly implemented safety Management system, the implementation of strict inspection and quarantine system and strengthen the control of production enterprises, the need for professional production qualifications can be produced, at the same time, the production and use of units need to strictly implement the maintenance system to ensure that the use and maintenance of safety, special equipment operators and maintenance personnel need to be professionally trained and assessed, and obtain the appropriate qualifications and then licensed to work.
The scope of the pressure vessel is provided for the maximum working pressure greater than or equal to 0.1MPa gas, liquefied gas and the maximum working temperature is higher than or equal to the standard boiling point of the liquid, the volume is greater than or equal to 30L and the inner diameter of greater than or equal to 150mm of the stationary and mobile containers; containers Nominal working pressure greater than or equal to 0.2MPa, and the product of pressure and volume greater than or equal to 1.0MPa?L gas, liquefied gases and standard boiling point equal to or less than 60 ℃ liquid cylinders; Oxygen tank.
