2022年11月5日 · An Orifice Flange is used in combination with orifice meters to measure the flow rate of oil, gas and other liquids conveyed by the pipeline. Orifice flanges are manufactured to ASME B16.36 in multiple sizes and, material grades.

Available for Class 300 applications and designed for easy assembly without welding. For larger sizes exceeding 24 inches, Texas Flange supplies orifice flange manufactured to the MSS SP-44 standard, ensuring superior performance even in the most demanding environments.

General installation instructions to install (or remove) the orifice plate are as follows: 1. Make certain the pipeline is not under pressure and has been drained or purged. 2. Loosen all studs and nuts. 3. Remove the studs in one half of the flange union. 4. Spread flange union by turning jackscrews clockwise. 5.

An Orifice flange is a disc-shaped flange, engineered with either a Raised Face or a Ring Type of Joint facing. The traditional orifice flange assembly consists of a pair of flanges, orifice plates, bolts, nuts, gaskets, jacking screws, and plugs.

The Rosemount 1496 Orifice Flange Union holds orifice plates in place for reliable flow measurement. This flange union is designed with a threaded tap connection (180-degrees apart) and engineered to withstand high temperatures and pressures of up to ANSI Class 2500#.

2024年12月13日 · An orifice flange assembly begins with matched flange pairs, which securely house the orifice plate, ensuring stability and accuracy. The orifice plate design, featuring critical orifice dimensions, is key in determining flow characteristics.

An orifice flange is a special type of flange used in piping systems to measure the flow rate of liquids or gases. It is part of an orifice meter setup, which also includes a pair of flanges, an orifice plate, gaskets, and pressure taps. The orifice plate, inserted between the two flanges, has a precisely measured hole through which the fluid ...

Install assembly in pipeline so that the Flow Directional Arrow is orientated in the direction of fluid flow and “Inlet” stamped on the orifice plate faces towards inlet flange. Assembly should be handled from the outside only. Do not damage inside. Flanges must be parallel and properly aligned to prevent cracking.

The traditional orifice flange assembly consists of a pair of flanges, orifice plate, bolts, nuts, gaskets, jacking screws and plugs, (where requested). The flanges are generally weld neck design. Other options are available such as Slip-on and threaded, although careful consideration should be taken in the location of the orifice tappings with ...

2024年12月20日 · Orifice Flange Assembly: Components, Installation, and Maintenance. An orifice flange assembly plays a crucial role in accurately measuring flow rates in pipelines by creating a controlled pressure differential. This system is widely used in industrial applications to ensure efficient and precise monitoring of fluid or gas flow.
