LPG Tank

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.

The process of installing the water mains outlet of the LPG storage tank
The water pump is connected to the fire water pipe and the fire water tank to ensure the continuity and reliability of the water supply. The pump outlet of the two pipelines must be equipped with check valves, once the pressure of the LPG pipeline is large, LPG will not reverse into the fire water pipeline.

LPG is a dangerous and explosive gas and when a leak occurs, a process solution of water injection and plugging can be adopted
Firstly because of the nature of LPG

The tank area is poorly protected against flammable gases and cannot be detected in time. If an ignition source is found, it may cause fire or explosion.Container explosion Ambient temperature rises in summer.

Storage tanks under normal temperature conditions have the characteristic that the storage pressure changes depending on the ambient temperature.

Classification of storage tanks: Storage tanks can be divided into full pressure storage tanks. Semi-refrigerated storage tanks Cooling tanks are filled according to the liquefaction method.

filling job
1. Open all valves in the liquid phase pipe between the liquid outlet and the dispenser. and open all valves in the return pipe.
2. Supply air to the fluid port pneumatic isolating valve to the open position, so that the liquefied petroleum gas in the storage tank communicates with the filling pump.
