Carbon Steel Orifice Flange

REQUEST A QUOTE

Carbon Steel Orifice Flange A carbon steel orifice flange is a specific type of flange designed for use in orifice metering applications. Orifice flanges are used to measure the flow rate of fluids within a piping system. They are commonly employed in industries such as oil and gas, petrochemical, and process engineering. When installing a carbon steel orifice flange, it is important to follow proper procedures, including accurate placement of the orifice plate and the use of appropriate gaskets. Additionally, selecting the correct orifice plate size and ensuring the flange is compatible with the process conditions are crucial for accurate flow measurement.
