Basic Info

Model No.: Orifice Flanges

Product Description

Orifice Flanges

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.
Orifice flange

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.

DATASHEETS AND DIMENSIONAL INFORMATION of Pipe Fitting
Orifice Flange manufacturer supplies Orifice Flanges, Plate Flanges,
  • ANSI 300 Flange - Orifice, Weld Neck, ANSI Class 300, B16.36 (in)
  • ANSI 400 Flange - Orifice, Weld Neck, ANSI Class 400, B16.36 (in)
  • ANSI 600 Flange - Orifice, Weld Neck, ANSI Class 600, B16.36 (in)
  • ANSI 900 Flange - Orifice, Weld Neck, ANSI Class 900, B16.36 (in)
  • ANSI 1500 Flange - Orifice, Weld Neck, ANSI Class 1500, B16.36 (in)
  • ANSI 2500 Flange - Orifice, Weld Neck, ANSI Class 2500, B16.36 (in)

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.

Coverage is limited to the following flanges:
  • WELDING NECK CLASSES 300, 400, 600, 900, 1500, 2500
  • SLIP ON CLASS 300
  • THREADED CLASS 300
Drawing of Orifice Flanges
Orifice Flanges generally come with either Raised Faces or RTJ (Ring Type Joint) facings. They are, for all intensive purposes, the same as weld neck and slip on flanges with extra machining.

Drawing of Orifice Flanges

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.

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.

Orifice flange union

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.

Orifice Flange manufacturer supplies Orifice Flanges, Plate Flanges, Orifice Plates Fittings in alloy steel, forged steel, ductile iron, Stainless Steel etc.

ASME B1.20.1 covers dimensions and gaging of NPT pipe threads for general purpose applications.

Orifice Flanges cover all standard sizes and ranges, and all common Flange materials

orifice unions come complete with gaskets, nuts, bolts and jack screws

Our orifice unions come complete with gaskets, nuts, bolts and jack screws and are made to b16.36 specifications.

Orifice Weld Neck Flanges
Orifice Weld Neck Flanges

Orifice Weld Neck Flanges are used instead of the standard pipe flanges when orifice plate or flow nozzle is used.

Advantages of Orifice Flanges:
  • It is used for measuring the fluid flow rate in the pipe.
  • It eliminates drilling and making bores on the pipes for inserting instrumentation probes.
  • These are cost saving devices to measure flow rate compared to other expensive methods.
  • Gives accurate readings of flow rate and very reliable.
