Multistage Restriction Orifice Plate Assembly

We are prominent manufacturer and supplier of Multistage Restriction Orifice Plate Assembly in Bhosari, Maharashtra, India. This is the next version of single stage restriction orifice plate. When the pressure is dropped across the orifice plate, the velocity is increased by large. For gas service, when the drop is nearer to 50% or more, this velocity approaches the velocity of sound or becomes more than that of sound velocity. The point at which the velocity is equal to the sound velocity is called as the Sonic condition. The sonic condition is not favorable for process line since it creates noise & vibrations. Also, more velocity causes erosion of plate bore. To avoid all these, the pressure is dropped in the number of plates arranged in series. The assembly of all these plates combined is called as multistage restriction orifice plate assembly. The selection of multistage depends upon the application or location where the pressure reduction is desired. If the application is venting in an atmosphere, exhaust to flare tank etc.
