Attachment: Safety valves and pressure gauges are mandatory for rigorous inspection. It is essential to report for inspection at the local quality supervision bureau to ensure better user experience. If the pressure gauge fails, you won't know the exact pressure used by your terminal, and you cannot use it with peace of mind, fearing issues with the liquefied gas storage tank. Both the air compressor and the storage tank itself have safety valves. When pressure exceeds the safe setting of the safety valve, it will automatically release pressure, and the pressure gauge plays a significant role. Therefore, daily accessories of special equipment must be used with caution. If any issues arise, first confirm whether the steel plate thickness of the storage tank meets the standard, and if not, determine the cause of the steel plate corrosion. Also, reconfirm that the safety valve, pressure gauge, and other auxiliary equipment meet the requirements. After all judgments are deemed不合格, the local technical supervision bureau of the enterprise issues an inspection不合格 notice, and the enterprise is required to replace the new pressure vessel upon receiving the notice.

1、Liquefied Petroleum Gas Storage TankSafe Operation: The pressure and temperature of the liquefied gas storage tank should be controlled to prevent overheating and overpressure. The causes of overheating and overpressure in the storage tank include the following:
(1) Operational Mistakes - To prevent operational mistakes, warning signs should be affixed to critical operational devices, clearly indicating the opening and closing directions of valves, their open/close states, and precautions, etc.
(2) Excessive Filling of Liquefied Gases Preventive measures against overfilling include: strictly filling according to the specified storage capacity; upon discovery of overfilling, immediately attempt to remove the excess; all instruments used for filling must be regularly inspected; the liquid level gauge should be periodically flushed; any residual liquid in the container should be included in the filling volume; its weight should not be ignored; when the surrounding temperature rises, spray cooling should be conducted.
