caustic solution piping

caustic solution piping

(OP)
I have to design piping system for 40% caustic solution at 25C,i take caustic solution from mixing vessel at 2m^3/h with the velocity of 1m/s,then diameter of pipe become 2.6cm which is i very small i guess.What is recommended velosity and diameter for this process ?

RE: caustic solution piping

2.6 cm ~ 1 inch pipe.

Good luck,

Technically, the glass is always full - 1/2 air and 1/2 water.

RE: caustic solution piping

What you are using (velocity of 1m/s, diameter 2.6cm) is appropriate.

with this values flow becomes laminar,will it make problems/errors during pump design ?

RE: caustic solution piping

No problems with laminar flow. The caustic will be dissolved as long as the temperature does not drop.

The 1m/sec is a typical flow rate for chemicals. You want to keep the flow rate between 1 to 2.5 m/sec. If you want, move down to the next pipe size.

RE: caustic solution piping

Spot on. 1 m/sec recommended for CS and up to 2.5 m/sec for SS in company guidelines for Caustic lines.
