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?
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.
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.
