Orifice plate showing vena contracta. An orifice plate is a thin plate with a hole in it, which is usually placed in a pipe. When a fluid (whether liquid or gaseous) passes through the orifice, its pressure builds up slightly upstream of the orifice [1] but as the fluid is forced to converge to pass through the hole, the velocity increases and the fluid pressure decreases.
Stainless steel has the material strength to withstand high pressures and resists chemical corrosion. Flow limiters are also capable of being designed out of nylon and fluoropolymers. For the connections to the flow limiter, there are a variety of ends featuring plain ends, pipe clamp ends, flanges, and compression fittings.
An orifice plate is a plate with a hole through it, placed perpendicular to the flow; it constricts the flow, and measuring the pressure differential across the constriction gives the flow rate. It is basically a crude form of Venturi meter, but with higher energy losses. There are three type of orifice: concentric, eccentric, and segmental. [7 ...
An orifice is any opening, mouth, hole or vent, as in a pipe, a plate, or a body Body orifice, any opening in the body of a human or animal; Orifice plate, a restriction used to measure flow or to control pressure or flow, sometimes given specialised names: Calibrated orifice, used to control pressure or flow

corrosion-resistant [steel] Largely synonymous with stainless steel, unless specific grades, specs, and distinctions are made on the drawing. Some people treat CRES as a subset of the stainless steels. CRS: cold rolled steel; on centres: Defines centre-to-centre distance of two features, such as two holes.

Stainless steel, also known as inox, corrosion-resistant steel (CRES), and rustless steel, is an iron-based alloy containing a minimum level of chromium that is resistant to rusting and corrosion. Stainless steel's resistance to corrosion results from the 10.5%, or more, chromium content which forms a passive film that can protect the material ...
