Orifice Flanges
An orifice flange is a disc-shaped flange designed with either a Raised Face or a Ring Type Joint facing. The standard orifice flange assembly includes a pair of flanges, an orifice plate, bolts, nuts, gaskets, jacking screws, and plugs. Jacking screws are used to facilitate the easy removal of the primary flow element.
Raj Industrials is a reliable and prominent supplier of orifice flanges in India. Orifice flanges serve as substitutes for typical pipe flanges when a stream nozzle or orifice plate is used. The primary function of an orifice flange is to provide access to a pipeline for the metering of gases or liquids. These flanges are typically used in conjunction with orifice metres to measure the flow rate of liquids and gases.
Orifice flanges are similar to standard welding neck and slip-on flanges but feature radial, tapped holes in the flange ring for metre connections and additional bolts that act as jack screws. These screws help in separating the flanges for inspection or replacement of the orifice plate. The choice between welding neck and slip-on types depends on the same considerations applied to standard flanges.
Raj Industrials ensures that its orifice flanges come with appropriate test certificates for both raw materials and finished products. When an orifice plate is installed between a pair of flanges in a pipeline, the entire assembly is referred to as an orifice flange assembly. This setup allows for precise flow measurement and is crucial for various industrial applications.
