Now many places need to use vehicle gas cylinders to transport gas, but we do not have a special understanding of what to do before and after filling vehicle gas cylinders. Next, Xiaobian will take you to understand
At the beginning, we must know what conditions should not be filled with gas. (1) Without the use registration or inconsistent with the use registration certificate; (2) exceeding the inspection period; (3) Those that fail to pass regular inspection or are scrapped; (4) New cylinders or cylinders filled after regular inspection have not been replaced or vacuum-pumped; (5) Have doubts about the safety of the gas cylinder and its gas system; (6) The crew of the gas vehicle department has not left the vehicle or there are other safety threatening circumstances.
Next, we will check the related items before filling the vehicle gas cylinder. If the problems found in the inspection must be properly handled, otherwise it is strictly prohibited to inflate the vehicle gas cylinder. (1) Whether the gas cylinder is manufactured by the manufacturing unit holding the manufacturing license, and whether the gas cylinder is required to be stopped or reinspected; (2) Whether the gas cylinder refit meets the regulations; (3) Whether the original mark of the gas cylinder meets the standards and regulations, and whether the handwriting of the steel seal is clearly visible; (4) Whether the gas cylinder is within the stipulated validity period of periodic inspection; (5) Whether the nominal working pressure marked on the gas cylinder conforms to the filling pressure specified for the gas to be filled; (6) Whether the paint color and wording of the gas cylinder comply with the provisions of the "Gas Cylinder Color Marking"; (7) Whether the gas cylinder accessories are complete and meet the technical requirements; (8) There is no residual pressure in the cylinder, and whether the residual gas is consistent with the gas to be filled; (9) Whether the valve and body of the cylinder containing oxygen or strong oxidizing gas are contaminated with grease; (10) Whether the gas cylinder newly put into use or used after regular inspection, replacement of the cylinder valve or discharge of the gas for some reason has been replaced or vacuum treated; (11) Whether the cylinder body has cracks, serious corrosion, obvious deformation, mechanical damage and other defects that can affect the strength and safe use of the cylinder. After filling, any gas cylinder must be inspected one by one by the inspector according to the specified inspection items. If it does not meet the technical requirements, it shall be properly handled. Otherwise, it is strictly prohibited to leave the station.
The basic items to be checked after filling the vehicle gas cylinder are: (1) whether the temperature of the cylinder wall is abnormal; (2) Whether there are defects of bulging, deformation, leakage or leak detection before filling of the bottle; (3) Whether the air tightness of the bottle valve and its connection with the bottle mouth is good, and whether the bottle cap and shock-proof ring are complete and intact; (4) Color marking and checking whether the color mark is complete and meets the technical requirements; (5) Sample and analyze whether the gas purity and impurity content in the bottle are within the specified range. (6) Whether the measured pressure and weight of the gas in the bottle or whether the pressure and weight are within the prescribed range.
