Orifice flanges are used instead of the standard pipe flanges when orifice plate or flow nozzle is used. The basic purpose for this is to measuring the flow rate of either gases or liquids in the respective pipeline.
These Fitting & Flange are used in various industrial applications and are available in various sizes and materials.
The range of orifice flanges covers all standard sizes and ranges, and all common flange materials. Flanges are available in Welding Neck Flange, Slip On Flange, and Threaded Flange, and are typically supplied with two 1/2" NPT tappings in each flange.
ASME B16.36 covers Dimensions and dimensional tolerances from orifice flanges (similar to those covered in Asme B16.5) that have orifice pressure differential connections.
Orifice flange for run installation should be so constructed, machined and attached to the that the inner surface of the passage extends through the orifice flange so that there is no recess at the orifice plate.
The Flanged Outlet bore and the section of pipe shall be of the same internal diameter.
Weldneck and Slip-On Orifice Runs
Weld Neck Orifice Run
Slip-on Orifice Run
1. End of Steel Flange should be reamed after cutting to ensure a perfectly smooth bore and should enter the flange as shown, for raised face flanges. For ring type joints the ends of the pipe should be a maximum of 3 mm from flange face.
2. The pipe should be drilled through each flange pressure tapping using a 12 mm drill for 4" bore pipe and over, a 10 mm drill for 3" bore pipe and a 6 mm drill for 2½" bore pipe and smaller.
Two Orifice Flanges are called an orifice flange union. Each flange comes with two pipe taps for measuring the pressure drop of the flow through an orifice plate.. Orifice plates do not come with the flanges and are sized based on the requirements of the process. Two jack screws are used to spread the flanges apart in order to change the orifice plate. This flange is normally available in weld neck, slip-on, and threaded flanges.
These flanges have a raised face. |
Orifice Flanges are installed in a straight run of pipe in order to avoid turbulence at the plate. As a rule of thumb, an orifice flange has ten diameters of straight pipe upstream and five diameters of pipe downstream.
Orifice flanges are used instead of the standard pipe flanges when orifice plate or flow nozzle is used. The basic purpose for this is to measuring the flow rate of either gases or liquids in the respective pipeline. These flanges are used in various industrial applications and are available in various sizes and materials.
