FOREWORD
August of 1956 marked the first recorded correspondence noting the lack of standardizationfor orifice flanges. There were, and still are, several codes for the performance and calibrationof orifice flanges, but there had been no standardization of the flanges themselves. Over theensuing 3 years, correspondence continued among the Instrument Society of America, AmericanGas Association, and the B16 Standards Committee.
On December 3, 1959, Subcommittee 3 (now Subcommittee C) of B16 authorized the appoint-ment of a Task Force to undertake drafting of a standard. Although the initial work progressedsmoothly, a controversy developed over the standard size of taps to be specified for the flanges.This required many years to resolve. It was finally achieved in 1973 with the issuance of a draftfrom the Task Force. Comments and objections to this draft from members of Subcommittee Cwere resolved, and a redraft was approved by the Subcommittee late in 1974. The B16 StandardsCommittee was balloted in the spring of 1975 and approval was gained. Comments from B16members from the gas industry requested that the Class 400 orifice flange be included, and theB16 Subcommittee C agreed to consider this for a possible addendum. The Standard was approvedby ANSI on August 15, 1975.
On April 30, 1979, an addenda was issued, which added Class 400 flanges andMandatory Appendix II covering reference documents and organizations.
In 1982, American National Standards Committee B16 was reorganized as an ASME Committeeoperating under procedures accredited by ANSI. In the 1988 edition, figures were added toillustrate jack bolts and corner taps, metric units have been omitted, and references to otherstandards have been updated. Following approval by the B16 Main Committee and the ASMESupervisory Board, the Standard was approved as an American National Standard by ANSI onFebruary 18, 1988.
In 1996, several revisions were made, including the addition of angular meter taps for ringjoint flanges in sizes not previously covered. Following approval by the B16 Main Committeeand the ASME Supervisory Board, the Standard was approved as an American National Standardby ANSI on November 6, 1996.
In 2006, several revisions were made, including the use of metric units as the primary referenceunits, while maintaining U.S. Customary units in either parenthetical or separate forms. Changesto dimensions and nomenclature followed that were contained within the 2003 edition ofASME B16.5. This includes the change of minimum flange thickness from C to tf and correctionsfor Y1 and Y2. Class 400 remains in U.S. Customary tables in Mandatory Appendix II, but is notgiven in the metric dimensional tables. There are numerous requirement clarifications and editorialrevisions. Following the approvals of the Standards Committee and ASME, approval for the newedition was granted by the American National Standards Institute on November 6, 2006.
In the 2009 edition, Mandatory Appendix III was revised and updated. Also, section 4, thematerials section, has been revised to cover requirements of material specification editions otherthan those listed in Appendix III of ASME B16.5.
Requests for interpretations or suggestions for revisions should be sent to the Secretary,B16 Committee, Three Park Avenue, New York, NY 10016-5990. As an alternative, inquiries maybe submitted via e-mail to: [email protected].
This revision was approved by the American National Standards Institute on August 13, 2009.

ASME B16.36-2009
ORIFICE FLANGES
1 SCOPE
This Standard covers flanges (similar to those coveredin ASME B16.5) that have orifice pressure differentialconnections. Coverage is limited to the following:
(a) welding neck flanges Classes 300, 600, 900, 1500,and 2500. U.S. Customary units are presented inMandatory Appendix I.
(b) slip-on and threaded Class 300.(c) welding neck flanges Class 400 in U.S. Customary
units in Mandatory Appendix II.
2 GENERAL
2.1 References
Codes, standards, and specifications containing provi-sions to the extent referenced herein constitute require-ments of this Standard. These reference documents arelisted in Mandatory Appendix III.
2.2 Quality Systems
Nonmandatory requirements relating to the productmanufacturer’s Quality System Program are describedin Nonmandatory Appendix A.
2.3 Relevant Units
This Standard states values in both metric and U.S.Customary units. As an exception, diameter of bolts andflange bolt holes are expressed in inch units only. Thesesystems of units are to be regarded separately as stan-dard. Within the text, the U.S. Customary units areshown in parentheses or in separate tables. The valuesstated in each system are not exact equivalents; there-fore, it is required that each system of units be usedindependently of the other. Except for diameter of boltsand flange bolt holes, combining values from the twosystems constitutes nonconformance with the standard.Except for Class 400, the values in U.S. Customary unitsare in Mandatory Appendix I. The main text of thisStandard does not contain requirements for Class 400welding neck flanges; however, Mandatory Appendix IIdoes contain requirements for this class, expressed inU.S. Customary units only.
2.4 Convention
For the purposes of determining conformance withthis Standard, the convention for fixing significant digitswhere limits and maximum and minimum values are
1
specified, shall be rounded as defined in ASTM PracticeE 29. This requires that an observed or calculated valueshall be rounded off to the nearest unit in the lastright-hand digit used for expressing the limit. Decimalvalues and tolerances do not imply a particular methodof measurement.
2.5 Denotation
2.5.1 Pressure Rating Designation(a) Class, followed by a dimensionless number, is the
designation for pressure–temperature ratings as follows:Classes 300 600 900 1500 2500.
(b) Class 400 is retained in the U.S. Customary tables.
2.5.2 Sizes. NPS, followed by a dimensionlessnumber, is the designation for the nominal flange size.NPS is related to the reference nominal diameter, DN,used in international standards. The relationship is, typi-cally, as follows:
NPS DN
1 2511⁄2 402 50
21⁄2 653 804 100
GENERAL NOTE: For NPS ≥ 4, the related DN p 25 (NPS).
2.6 Service Conditions
Criteria for selection of materials suitable for the par-ticular fluid service are not within the scope of thisStandard.
3 PRESSURE–TEMPERATURE RATINGS
The pressure–temperature ratings, including all userecommendations and limitations, and the method ofrating given in ASME B16.5 apply to these flanges.
4 MATERIAL
4.1 General
Flange materials shall be in accordance with therequirements of ASME B16.5. For materials manufac-tured to editions of the material specification other thanthose listed in Appendix III of ASME B16.5, refer topara. 4.3.

Bolting material recommendations are given inASME B16.5. For materials manufactured to editionsof the material specification other than those listed inAppendix III of ASME B16.5, refer to para. 4.3.
4.3 Materials Manufactured to Other Editions
Materials may meet the requirements of material spec-ification editions other than those listed in Appendix IIIof ASME B16.5, provided
(a) the materials are the same specification, e.g.,grade, type, class, or alloy, and heat-treated conditions,as applicable
(b) the flange manufacturer certifies that the require-ments of the edition of the specification listed inAppendix III of ASME B16.5 have been met
4.4 Plugs
Pressure-retaining plugs shall conform toASME B16.11, unless otherwise agreed between pur-chaser and manufacturer. Plug material shall be at leastas corrosion resistant as the corresponding flangematerial.
5 SIZE
Orifice flange sizes are indicated by the nominal pipesize to which they are attached. Only those listed inTables 1 through 5, Tables I-1 through I-5, andMandatory Appendix II are considered standard.
6 MARKING
Flanges shall be marked as required in ASME B16.5.For welding neck flanges only, the bore diameter shallbe marked.
7 FLANGE FACING FINISH
The finish of contact faces shall conform to the require-ments of ASME B16.5.
8 GASKETS FOR RAISED FACE FLANGES
8.1 Gasket Thickness
Flange dimensions are based on the use of 1.5 mm(0.06 in.) thick gaskets.
8.2 Flange Gaskets Requiring Dimensional Changes
When the location of the pressure tap with respect tothe orifice plate is critical to the service and meteringconditions, its location may be altered to accommodateother than 1.5 mm (0.06 in.) thick gaskets or ring-typejoint gaskets whose thickness may vary from that listedin Tables 2, 3, 4, and 5 or those listed in Tables I-2, I-3,I-4, and I-5 or Mandatory Appendix II.
2
The alteration of location may also be accomplishedby the removal of 2 mm (0.06 in.) from the raised faceof the flange. If an original 2 mm (0.06 in.) high raisedface is removed, the user is cautioned to limit the outsidediameter of the gasket or orifice plate to the tabulatedR dimension.
9 PRESSURE TAPS
9.1 General
Each orifice flange shall be provided with two pres-sure tap holes extending radially from the outside diam-eter of the flange to the inside diameter of the flange.Corner taps may be used on NPS 11⁄2 and smaller ifspace permits. See Fig. 1.
For ring joint flanges listed in Tables 2 through 5,Tables I-1 through I-5, and Mandatory Appendix II,where radial taps will interfere with the ring groove,angular meter taps, as illustrated in Fig. 2, will berequired. Each pressure tap hole shall be equipped witha pipe plug.
9.2 Location
9.2.1 Measurement. The 24 mm (0.94 in.) dimensionfor raised face and 19 mm (0.75 in.) for ring joint shallbe measured at the bore.
9.2.2 Identification. For ring joint flanges requiringalteration of pressure tap location due to interferencewith the ring groove other than methods provided inthis Standard, such alteration shall be identified peragreement between purchaser and manufacturer.
9.3 Pipe Connection
Unless otherwise specified, pressure tap holes may beeither tapped 1⁄2 NPT in accordance with ASME B1.20.1or 1⁄2 NPS socket connection in accordance withASME B16.11.
10 JACK SCREW PROVISION
10.1 Location
Each flange shall have a machine bolt mounted in ahole drilled on the flange bolt circle centerline at 90 degfrom the pressure taps, for use as a jack screw. Themachine bolt shall be regular with one heavy hex nut.See Fig. 3.
10.2 Slot for Nut
A slot shall be provided in the flange 2 mm (0.06 in.)wider than the width across flats of the nut. The depth ofthe slot shall admit the nut so that there is no interferencewith the joining of the flanges when bolted togetherwithout orifice plate.
ASME B16.36-2009
10.3 Tapped Hole
As an alternative to para. 10.2, a tapped hole maybe provided and the hex nut omitted when agreed onbetween the purchaser and the manufacturer.
11 FLANGE DIMENSIONS
Dimensions are listed in Tables 1, 2, 3, 4, and 5 formetric, and Tables I-1, I-2, I-3, I-4, and I-5, andMandatory Appendix II for U.S. Customary.
12 FLANGE THREADS
Threaded flanges shall have an American NationalStandard taper pipe thread conforming toASME B1.20.1.
(a) The thread shall be concentric with the axis of theflange. Variations in alignment shall not exceed 5 mm/m(0.06 in./ft).
(b) The flanges are made with counterbores at theback of the flange and the threads shall be chamferedto the diameter of the counterbore at an angle of approxi-mately 45 deg with the axis of the thread to afford easyentrance in making a joint. The counterbore and chamfershall be concentric with the thread.
(c) In order to permit the pipe to be inserted to theface of the flange, the threads should have full root
3
diameters through to the face of the flange, or shall havea counterbore at the face of the flange.
(d) The gaging notch of the working gage shall comeflush with the bottom of the chamfer in all threadedflanges and shall be considered as being the intersectionof the chamfer cone and the pitch cone of the thread.This depth of chamfer is approximately equal to one-halfthe pitch of the thread.
(e) The maximum allowable thread variation is oneturn large or small from the gaging notch.
13 TOLERANCES
Tolerances on all dimensions shall be as shown inASME B16.5 except for those shown below.
13.1 Pressure Tap Location
Tolerance on location of center of pressure tap hole1
from flange face shall be(a) ±0.5 mm (±0.02 in.) for flanges smaller than NPS 4(b) ±0.8 mm (±0.03 in.) for flanges NPS 4 and larger
13.2 Bore Diameter
Bore diameter tolerance (welding neck flanges only)is ±0.5% of nominal value.
