Oriface Flanges

Use :

Orifice Flanges by Tirupati Enterprises

Orifice Flanges are specifically designed for use with orifice meters, allowing for accurate measurement of fluid or gas flow rates in pipelines. These flanges come with pressure tappings—typically positioned on two opposite sides—eliminating the need for separate orifice carriers or tappings in the pipe wall.

Design & Features

Orifice Flanges are available in Raised Face (RF) and Ring Type Joint (RTJ) facings. Structurally, they resemble weld neck and slip-on flanges, but with additional machining to accommodate pressure tappings.

The image illustrates a typical Orifice Flange assembly, where an Orifice Plate is mounted, along with a jack screw. This jack screw is crucial in separating the flanges for easy inspection or replacement of the Orifice Plate and gaskets.

Material & Specifications

Our Orifice Flange range includes various sizes, pressure ratings, and materials to meet industry standards. These flanges are available in:

  • Welding Neck Flanges (Classes 300, 400, 600, 900, 1500, 2500)
  • Slip-On Flanges (Class 300)
  • Threaded Flanges (Class 300)

Each Orifice Flange is typically supplied with two ½” NPT tappings, ensuring compatibility with industry requirements.

Standards & Compliance

Our Orifice Flanges conform to ASME B16.36, which specifies dimensions and tolerances similar to ASME B16.5 but with additional provisions for orifice pressure differential connections.
