The restriction orifices are used for reducing fluid pressure and are designed somewhat different the orifice
plates that are used for meassuring flow rates.
There are some types of restriction orifices, including a single plate with a single hole, a single perforated
plate(having diffused holes), and a set of welded multi orifices (a multistage orifice) which are used for
high-pressure high-temperature fluids.
The bore edge of the restriction orifices can be surface-hardened with stellite welding or by nitrification.
