Use of Nitrogen Purging 1

[Shane33-Simba]

Can someone tell me, if nitrogen purging is required for hydrocarbon lines only or if it also required for fire water lines / tanks as well?

In general you only need nitrogen purging if there is a risk of otherwise getting an explosive or flammable atmosphere in the pipe either when you're emptying the pipe or filling it.

Fire water is not flammable so therefore no, however you could use it to preserve the lines after testing and drying if commissioning is going to be a long way away or if you mothball it.

Bro,
V Good article, thanks a lot for your help.

Water is not flammable, so the obvious answer is 'no'. But...

Here you can find a video how a water tank exploded and launched, accounted for 1 killed
Here you can find a report how a water pump station exploded and collapsed, accounted for 16 killed and 28 injured
Here you can find a record how a water tank exploded and launched, accounted for 2 killed (see para. 11.4.2.f)
Here you can find a record how a water sewer system (containing only the negligible traces of hydrocarbons of the order of ppm) exploded, accounted for 1 killed (see case 1.3)
And such stories are not sporadic. You can find more just by googling.

It is up to you to decide whether those are irrelevant to your particular case or not.
