Liquefied gas storage tank production and manufacturing

LPG is a volatile, colourless liquid obtained by liquefying natural gas or petroleum under pressure or reduced pressure in refining plants. It is highly spontaneous and can explode when exposed to open flame if its concentration in the air exceeds a certain level. The density of LPG in the liquid state, which decreases as the temperature increases, increases as the temperature decreases.

LPG cylinder is a kind of pressurised container, which should be well maintained and regularly inspected.

The Liquid Fill System reduces product losses by preventing overfilling the liquid cylinders. Every minute of overfilling results in a 30% reduction of the container’s capacity.Issues with the Department of Weight and Measures over the overfull containers

As liquid LPG is lighter than water, the water injected into the tank will hold the LPG to the water surface, isolating the LPG from the leak. At this point, the main spray from the leak is water rather than pure LPG, and then other methods are used to plug the leak. In the process of plugging the leak, the release valve at the top of the tank can be opened to release the gaseous LPG, which is less likely to form a hazard and reduces the pressure in the tank.

Common LPG tank materials include carbon steel and low-temperature alloy steel.
