Stand pipe applications

Stand pipe applications

Stand pipe applications

(OP)
Hi,
What is the reason for using "Satand pipe"?
Does the "providing NPSHA" is only application for stand pipe?
What is "Stand pipe's" definition?

Thanks for replies

RE: Stand pipe applications

It shouldn't necessarily be a pipe. It is generally a vertical open (generally large) reservoir filled with material, for example water to provide for constant downstream pressure, or as in FCC units in petroleum refineries filled with aereated catalyst serving also as a seal between high- and low-pressure parts of the process equipment.

RE: Stand pipe applications

It might help to indicate what you are looking at exactly.

In the water tank industry, a standpipe is any tank taller than it is wide.  In many cases, it is just the equivalent of an elevated tank or water tower.  In other cases, just a ground storage tank that happens to have dimensions that fall into that category.

In building construction, it is a piping arrangement- but I'm not really familiar with those.

The petroleum application above indicates a third usage with which I'm also not familiar.

thank you.
It is just my ciriosity. I like to know other's opinion and experience in this matter.

Thank you again for sharing your knowledge.

RE: Stand pipe applications

Definition of standpipe from Websters:

"A vertical pipe, open at the top, between a hydrant and a reservoir, to equalize the flow of water; also, a large vertical pipe, near a pumping engine, into which water is forced up, so as to give it sufficient head to rise to the required level at a distance".

Probably relates to NPSHA (sufficient head) on your pump.
