1 Scope

China's national safety rules for gas cylinders in transit, in store and in use. It specifies the safety technical requirements for handling, loading and unloading, storing and using cylinders in the places where those things happen, and it applies to cylinders used at ambient temperatures from minus 40 to 60 degrees C. A gas cylinder is one of the few genuinely dangerous objects that circulates through ordinary workplaces without ceremony. It is a pressure vessel holding gas at up to two hundred times atmospheric pressure, and it is carried by hand, moved on trolleys, left standing against walls and used by people with no engineering training. If it falls and the valve breaks off, the cylinder becomes a projectile capable of going through a brick wall. If it is stored next to an incompatible gas, or in the sun, or in a stairwell, the consequences of any other failure multiply. Almost everything in this standard is a rule about handling rather than about the cylinder itself, because that is where the accidents happen.

This standard specifies the basis for handling, handling, storage and use of bottled gas cylinders in the areas of use, storage, operation and storage of such places This safety technical requirement. This standard applies to the normal ambient temperature -40 °C ~ 60 °C under the use of a nominal volume of 0.4L ~ 3000L, nominal working pressure Force of 0.2MPa ~ 35MPa (gauge pressure, the same below) and the product of pressure and volume greater than or equal to 1.0MPa · L, containing compressed gas, high (Low) liquefied gas, cryogenic liquefied gas, dissolved gas, adsorbed gas, liquids having a normal boiling point equal to or lower than 60 ° C. and a mixed gas Body of seamless cylinders, welding cylinders, welding insulated cylinders, wrapped cylinders, filled with gas cylinders. This standard does not apply to only withstand instantaneous pressure in fire when stored without pressure on the fire extinguisher cylinders, fixed use Bottled pressure vessels as well as military equipment, nuclear facilities, aerospace vehicles, railway locomotives, offshore installations and ships, and specialized equipment for civilian airports Gas cylinders, car gas cylinders, long tube trailers, large volume cylinders for tube bundle vehicles.
