Pipe into tank

[tranduyquang]

Hi,

On an P&ID, I saw that distance between the end of inlet pipe and the tank bottom is 200mm. So, can anyone tell me why we have to do that? And, can I adjust this parameter, e.g. 150mm or 300mm? Thank a lot!

The question become too difficult when you hide all related info. such as Nozzle services (In or outlet, flushing,...), and contained fluid info.

There're some reason to install the inner pipe as your sketch. Please inform further information as I mentioned so SO can help you in quick

Thank for your attention. The full P&ID is as below:

There are two reasons for doing it this way:

1) Splash filling any liquid is best to be avoided as it can generate static sparks which may cause fire/explosions. Extending the fill pipe into the tank will allow you to fill into the bulk liquid rather than free-falling from the top. Additionally, if you look at the liquid outlet to the injection pumps, you will see that this is 150 mm above the bottom of the tank. This means that even when the tank has been emptied to it's minimum operating level, there is only a 50 mm gap between the liquid level and the fill pipe, this is probably sufficient to prevent the generation of significant static charge

2) Terminating the fill pipe at a level above the tank bottom will also help prevent erosion of the tank shell from being impacted by the liquid entering. This is especially important when the liquid is entering under pressure (I presume that the tote tank is located a deck or two above the main storage tank). This is of more importance if you are filling a tank that has been previously drained.

@gtaa: thank you for helping me.
