Orifice plate is a device used for measuring flow rate, for reducing pressure or for restricting flowThe orifice plate is a metal disk with a concentric hole in it, which is inserted into the pipe carrying the flowing fluid. Orifice plates are simple and available in a wide range of sizes.
The orifice plate with flange assemblies are employed for measuring the rate of flow or quantity of moving fluids like liquids, gases or vapors. They are comprised of Gaskets, Hardware and Orifice Flanges that contain pressure sensing ports. It is designed to transfer stresses to the pipe, thereby reducing high stress concentration at the base of the flange.
Restriction orifices are used to reduce the fluid pressure or to restrict the flow rate in a pipe work. In case the target pressure drop cannot be achieved with a single plate, a multi-stage restriction orifice assembly is required. It is composed of several orifice plates, each of them reducing the fluid pressure to its maximum capacity. It allows reducing the pressure in different steps (multiple stages) to achieve the total required pressure drop while preventing problems such as noise, vibration and cavitation. Orifice sizing done for correct design by Conval sizing software.
Venturi tubes are reliable, easy to use and low-maintenance suitable for liquid, gas and steam flow measurement and designed for use where low pressure-loss is required. Venturi tubes can be installed horizontally, vertically or any angle in between and have shorter upstream piping requirements to simplify installation and reduce costs.
