Multistage Orifice Assemblies consist of several orifice plates installed in the same
pipe. This allows the pressure to gradually be reduced to the desired pressure. Compared
to a single orifice, a multistage assembly reduces the pressure in smaller increments
which reduces cavitation and noise. A typical application would be to reduce the pressure
from 2500 psi down to atmospheric pressure. The assembly could consist of five stages
(orifices) each causing a 500 psi pressure drop. Imperial Flange will manufacture custom
assemblies to meet your needs.
The images below show a multistage orifice assembly at various stages of manufacture.
