For low-pressure liquefied gas cylinders, the charging unit should first perform a calibration to confirm that the gas to be replaced can be modified only after the saturated vapor pressure at the temperature of the cylinder is not greater than the allowable pressure of the cylinder.

　　3. When the gas cylinder is refitted, the inside of the cylinder should be thoroughly cleaned and inspected, the corresponding accessories should be replaced, and the sample, color circle and color mark of the gas cylinder should be changed according to the GB7144 gas cylinder color labeling regulations.
