Minimum Pipeline Velocity of Brine?

Minimum Pipeline Velocity of Brine?

Minimum Pipeline Velocity of Brine?

(OP)
Hello,
Is there an industry standard for a minimum pipeline velocity for brine? For sewage, I've heard anything from 2-3 fps. Is there a required minimum pipeline velocity for brine?

RE: Minimum Pipeline Velocity of Brine?

None I'm aware of.

Normally min velocities are to ensure "solid material" still moves.

Brine is all liquid no?

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

RE: Minimum Pipeline Velocity of Brine?

In most brine service erosion/corrosion is a major concern.
If there are solids in the brine then you have a lot of issues to deal with.

RE: Minimum Pipeline Velocity of Brine?

"Brine" is a rather vague term and can be anywhere from 3.5% to 25% salt to water.

Warm aerated brine eats most metals...

Any more information you can supply?

RE: Minimum Pipeline Velocity of Brine?

Water treatment brine is 26% concentration and completely dissolved. One can use the same velocities as that used for water (3-5 ft/sec).

RE: Minimum Pipeline Velocity of Brine?

The cravat to Bimr's comment is 'are you allowing for any corrosion?'
If so then lower velocities are in order so that you don't scour corrosion products off of the surface and accelerate corrosion.
That said if your material does not tolerate 5ft/sec then in truth you have the wrong material.

RE: Minimum Pipeline Velocity of Brine?

IMHO... I agree with all of the comments above .... Once more we do not know enough about the specifics of the problem

But it also sounds like the OP is confused and does not know if he has a slurry system or not ....

The design of slurry piping systems is COMPLETELY different than other systems

This would be a better question for a process chemical forum .... or perhaps the "Pipelines, piping and Fluid Mechanics" forum

There should be better and more knowledgable eyeballs there

RE: Minimum Pipeline Velocity of Brine?

Any piping and valves that are in direct contact with either 10% to 26% salt should preferably be constructed of Schedule 80 CPVC, Schedule 80 CPVC, polypropylene, or piping lined with a non-metallic.
