What is Oriface Flanges?
An Oriface Flange is a specialized type of flange used in conjunction with orifice plates to measure the rate of flow of liquids or gases in a pipeline. These flanges come with pressure tap holes and are installed as a pair—upstream and downstream of the flow—to precisely monitor differential pressure. As one of the trusted Oriface Flanges Suppliers, Metafit Piping Industries produces flanges that are engineered to align perfectly with flow meters, ensuring minimal loss and maximum efficiency in pipeline systems.
Advantages of Oriface Flanges?
The advantages of using Oriface Flanges are substantial. They offer a simple and reliable method for flow measurement without complex machinery. Installation is straightforward, and maintenance is minimal compared to inline flow devices. Our position as experienced Oriface Flanges Exporters means our products are designed with global end-users in mind, offering compatibility with major international pipeline systems. With cost-effective fabrication and long operational life, Oriface Flanges are a smart investment for flow regulation in demanding environments.
