ASME B16.36 OWN RF Flange ASTM A182 F316L Stainless Steel Orifice Weld Neck Flange
Orifice flanges are designed with a specific bore size or orifice plate installed between the flanges. The orifice plate creates a restriction in the pipeline, causing a pressure drop that is directly related to the flow rate of the fluid passing through the orifice. There are different types of orifice flanges, such as weld neck orifice flanges, slip-on orifice flanges, and threaded orifice flanges. The choice of type depends on the specific application requirements and installation preferences. The primary function of stainless steel orifice flanges is to accurately measure the flow rate of liquids or gases in a piping system. By measuring the pressure drop across the orifice, the flow rate can be calculated using established formulas.
