Single Stage Restriction Orifice Plate

IPS Automation supplies restriction orifice plates in India for controlled pressure reduction and flow limitation in liquid, gas and steam services. Each requirement should be reviewed using the actual process conditions because pressure ratio, fluid phase, noise, velocity, cavitation and flashing can affect the correct design.

Restriction Orifice Selection in India

A single-stage restriction orifice can suit duties where the required pressure reduction remains within acceptable operating limits. Multihole or multistage arrangements can be reviewed when the pressure drop should be distributed to manage noise, vibration, velocity, cavitation or flashing. Final selection requires an engineering review of complete process data.

Calculation and Quotation Inputs

Please provide fluid composition and phase, minimum normal and maximum flow rate, upstream and downstream pressure, operating and design temperature, pipe size and schedule, piping material, required orifice material, flange standard, allowable noise limit and inspection documentation.

Common Configurations

Project requirements can be reviewed for single-hole, multihole, single-stage and multistage arrangements. Material, bore configuration, thickness, tapping arrangement and assembly details must follow the approved calculation and project specification.

Frequently Asked Questions

What is the difference between a measurement orifice plate and a restriction orifice? A measurement orifice is used as a primary flow element with differential pressure measurement. A restriction orifice is mainly selected to limit flow or reduce pressure.

When is a multistage restriction orifice considered? It can be considered when the total pressure reduction should be divided into stages to control operating risks.
