Safety function of carbon dioxide storage tank

Replacing the CO2 Storage Tank Level Gauge

Content

The normal inspection of the storage tank checks whether the valves are in normal condition. Check whether the indications of the pressure gauge and liquid level gauge are normal and whether the response is sensitive. Whether there is leakage in equipment, flanges, pipes, valves and joints. When the valve is frozen and difficult to operate, it should be thawed with hot air at 70 to 80 degrees or heated with hot water. It is strictly forbidden to hit with a hammer, fire or electric heating. When it is out of service for a short time, do not release all the gas in the storage tank. Depending on the length of the interruption, keep 5% to 10% of the liquid volume to reduce evaporation loss during refilling.
