For compressed gas or liquefied gas cylinders, the main purpose is to prevent the outside gas from being poured into the cylinder after the cylinder is cold, thus causing safety hazards of the cylinder.
For inert gas cylinders, if the gas is poured after the gas is exhausted, the air, oxidizing or flammable gas is not dangerous to inject itself. However, when the inert gas is filled, the cylinder is usually not washed if the process used is oxidizing or flammable. Sexual gases are extremely sensitive and are highly prone to accidents when used.
For oxidizing gas cylinders, if the flammable gas is poured into the cylinder after the gas is exhausted (for example, if there is paint or flammable gas in the environment), it is extremely prone to accidents after returning to the filling factory;
For flammable gas cylinders, if the gas is poured after the gas is exhausted, the air and oxidizing gas are poured into the gas cylinder, and the accident is extremely prone to accidents during the later filling and use.
Gas cylinder with dissolved properties
For gas cylinders with dissolved properties, it is more forbidden to use up.
For example, an acetylene cylinder with a mixture of diatomaceous earth and acetone is used to dissolve acetylene to reduce the cylinder pressure and increase the total amount of acetylene contained in the cylinder. If the pressure is too low, it will cause the volatilization of acetone or other solvents, which will result in the failure to obtain the filling pressure and the filling amount next time. If it is used after forced filling, it will be prone to explosion.
Electronic special industry gas cylinder
For the electronic special gas industry
No gas supplier can guarantee that the gas at the bottom of the bottle (or low pressure section) is acceptable.
Preventing other gas from being polluted, it can eliminate safety hazards and eliminate quality hazards.www.wxytgas.com
