What is a Slip On Orifice Flange Union?
A Slip-On Orifice Flange Union is a type of flow measurement device used in piping systems to measure the rate of fluid flow. It consists of a slip-on flange, which slides over the pipe and is then welded in place, and an orifice plate, which is inserted between the flanges to create a pressure drop that can be measured to determine flow rate. This design allows for easy installation, inspection, and replacement of the orifice plate, making it a practical and cost-effective solution for flow measurement in various industrial applications, including oil and gas, water treatment, and power generation.
