What is an Duplex Steel Orifice Plate Flanges?

An Duplex Steel Orifice Plate Flanges is a disc-shaped flange, engineered with either a Raised Face or a Ring Type Joint facing. The traditional Duplex Steel Orifice Plate Flanges assembly consists of a pair of flanges, orifice plate, bolts, nuts, gaskets, jacking screws and plugs. Jacking screws ensure the easy removal of the primary flow element.

An Duplex Steel Orifice Plate Flanges is used in combination with orifice meters to measure the flow rate of oil, gas and other liquids conveyed by the pipeline. Duplex Steel Orifice Plate Flanges are manufactured to ASME B16.36 in multiple sizes and, material grades.
An Duplex Steel Orifice Plate Flanges is used to measure the flow of the fluid conveyed by the pipeline via a flow nozzle positioned on the flange itself. Pairs of pressure tappings are machined onto the Duplex Steel Orifice Plate Flanges, making separate tappings on the pipe wall unnecessary.
An Duplex Steel Orifice Plate Flanges is a disc-shaped flange, engineered with either a Raised Face or a Ring Type Joint facing.

How does an Duplex Steel Orifice Plate Flanges work?

The function of the Duplex Steel Orifice Plate Flanges is to measure the rate of the flow of the commodity through the piping system. Duplex Steel Orifice Plate Flanges are easy to recognize because they have a hole drilled through the face of the flange perpendicular to the pipe. They also have an additional set of bolts called jack screws.

What is the function of an orifice?

An orifice plate is a device used for measuring flow rate, for reducing pressure or for restricting flow (in the latter two cases it is often called a restriction plate ).

Tolerances

D1 & D2 = ± 1%
D3 = ± 1 mm
D4 = 0/-0.4 mm
L = ± 0.1 mm
N = see note 6
P = ± 0.1 mm
S = ± 0.1 mm
T = see note 2
Notes:
  1. Marking
    The Upstream side of the orifice tab shall be stamped at the indicated locations with:
    - the word UPSTREAM
    - the Tag Number
    - the ASME flange class, followed by RF
    - the nominal pipe size (NPS)
    - the measured orifice D1 (in mm)
    - the material of the orifice plate
    - the type of orifice plate (Square, Restriction etc.)
    Letter height approx. 4 mm
  2. Welding of tab
    Tab may be integral with orifice plate up to and including 7 mm plate thickness.
    In other cases full penetration joint to be applied.
  3. Finish of plate
    The upstream and downstream faces of the orifice plate to a diameter equal to D3 shall have a surface roughness Ra ≤ 0.8 µm ASME B46.1.
    The remaining annular part (between D4 & D3) of upstream and downstream faces shall have a surface roughness Ra between 3.2 and 3.6 µm ASME B46.1. This finish shall be obtained by machining with a round nosed cutting tool having a 0.8 mm radius at a feed rate between 0.35 and 0.45 mm per revolution.
  4. Concentricity
    The centre of the orifice shall not differ from the centre of the plate by more than 0.1 mm for ≤ NPS 8 and 0.2 mm for > NPS 8.
  5. Finish of throat
    The throat and outlet cone shall have a surface roughness Ra ≤ 0.4 µm ASME B46.1.
    All edges shall be sharp and free from burrs, so that when viewed with the naked eye no light is reflected by the corners.
  6. Plate thickness
    The difference between any two measurements of plate thickness, for annular part D1-D3, shall not differ by more than 0.001 DN in mm.
    The plate shall not depart from flatness along any diameter by more than 0.01 D3.
    Tolerance for N shall be:
    N ≤ 6 mm +0.1/-0.25 mm
    N > 6 mm +0/-1.5 mm
    Thickness for annular part D3-D4, may be slightly less, max 0.05 mm, due to surface finishing difference between D1-D3 & D3-D4. (see note 3)

General notes:

  • Dimensions are in millimeters unless otherwise indicated.
  • Allowable pressure difference 20 bar for temperatures up to 400 °C and D1/D3 ≥ 0.1. The thickness of the plate needs to be verified for strength in case the pressure difference is higher than 20 bar and/or the temperature is beyond 400 °C. Based on the outcome of the calculation the thickness of the plate needs to be adjusted.
  • DIA D1 & DIA D2 - to be specified by purchaser.
  • Material to be specified by purchaser.
