Product Overview
Restriction Orifice (Pressure-Reducing Orifice)
Restriction orifices are used to reduce fluid pressure and are designed somewhat differently from orifice plates for flow measurement.
Restriction orifices come in several types: a plate with a single hole, a multi-hole plate with several distributed holes, and a multi-stage orifice (Multistage Orifice) with several orifice plates welded together for high-pressure, high-temperature fluids.
The bore edge of a restriction orifice can be surface-hardened by Stellite (Stellite) welding or nitriding (Nitrification).
English description
The restriction orifices are used for reducing fluid pressure and are designed somewhat different the orifice plates that are used for measuring 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.
