FOREWORD

(This Foreword is not part of ASME B1 6.9-1 993.)

In 1921, the American Engineering Standards Committee, later American Standards As- sociation (ASA), organized Sectional Committee B16 to unify and further develop national standards for pipe flanges and fittings (and, later, for valves, gaskets, and valve actuators). Cosponsors of the B16 Committee were the American Society of Mechanical Engineers (ASME), the Heating and Piping Contractors National Association [now the Mechanical Contractors Association of America (MCAA)], and the Manufacturers Standardization Society of the Valve and Fittings Industry (MSS). Cosponsors were later designated as cosecretariat organizations.

Standardization of welding fittings was initiated in 1937 by a subgroup (designated Sub- group 6) of Subcommittee No. 3. After consideration of several drafts, a standard was approved by the Committee, cosponsors, and ASA, and published with the designation ASA

Revisions were made in 1950 and 1955 to add sizes up to NPS 24 and to complete coverage of fittings in some sizes. These revisions were approved and published as ASA B16.9-1951 and ASA B16.9-1958. With the subgroup now designated Subcommittee No. 6 (later Sub- committee F), further revisions were begun to clarify the intent of the standard, to add an- gularity tolerances, and to include fittings of different types (long radius reducing elbows and crosses) and smaller sizes (NPS '/4 and %). This revision was published as ASA B16.9- 1964 after ASA approval.

After reorganization of ASA, first as the United States of America Standards Institute (USASI), then as the American National Standards Institute (ANSI), with the Sectional Committee being redesignated as an American National Standards Committee, another revision increasing the size range to NPS 48 and revising the text for clarity was approved and published as ANSI B16.9-1971.

In 1975, Subcommittee F began a major revision to bring the standard up to date with current practice and usage. Common fractions were expressed as decimals (but without in- tending higher precision) and metric dimensional equivalents were added. Provisions for step-wise change of radius for NPS 3/4 long radius elbows and 180 deg. returns were intro- duced. Following Standards Committee, cosecretariat, and ANSI approval, the revision was published as ANSI B16.9-1978. It was updated by a corrective addendum, B16.9a- 1981, issued in February 1982.

In 1982, American National Standards Committee B16 was reorganized as an ASME Committee operating under procedures accredited by ANSI. In this edition, the text has been revised and inch dimensions are established as the standard. Following approval by the Standards Committee and ASME, approval as an American National Standard was given by ANSI on November 12, 1986 with the new designation ASME/ANSI B16.9-1986.

In 1991 the Subcommittee reviewed the document and made a number of revisions. Di- mensions for short pattern lap joints were also added to this 1993 Edition of the Standard.

Requests for interpretation or suggestions for revision should be sent to the Secretary, B16 Committee, The American Society of Mechanical Engineers, United Engineering Cen- ter, 345 East 47th Street, New York, NY 10017.

In 1991 the Subcommittee reviewed the.document and made a number of revisions. Dimensions for short pattern lap joints were also added to this 1993 Edition. This Edition was approved by ASME, and by ANSI on January 22, 1993.

Requests for interpretations or suggestions for revision should be sent to the Secretary, B16 Committee, The American Society of Mechanical Engineers, United Engineering Center, 345 East 47th Street, New York, NY 10017.

ASME B1 6.9-1 993

FACTORY-MADE WROUGHT STEEL BUTTWELDING FITTINGS

1 SCOPE

1.1 General

This Standard covers overall dimensions, tolerances, ratings, testing, and markings for wrought carbon and alloy steel factory-made buttwelding fittings of NPS Y2 through 48. It covers fittings of any produc- ible wall thickness.

1.2 Exclusions

This Standard does not cover low pressure corro- sion resistant buttwelding fittings. See MSS SP-43, Wrought Stainless Steel Butt-welding Fittings. -

1.3 Partial Compliance Fittings

Fittings may be made to special dimensions, sizes, shapes, tolerances, or of wrought materials other than those covered by this Standard by agreement between the manufacturer and the purchaser. When such fittings meet all other stipulations of this Standard, they shall be considered as being in partial compliance therewith, provided they are appropriately marked. (See para. 4.4.)

1.4 Fabricated Fittings

Fabricated laterals and other fittings employing cir- cumferential or intersection welds are considered pipe fabrication, and shall be manufactured in accordance with the applicable section of ASME B31, Code for Pressure Piping.

1.5 Standard Units

The inch is the standard unit for linear dimensions. Values in millimeters are for information and reference only. See Annex A.

O NOTES: (1) Tolerance values shown in Table 1 in decimal inches are com-

mon fractions rounded as follows:

1

0.03 = '/32 0.12 = VI3

0.06 = 0.16 = 5/32

0.09 = 3/32 0.19 = 3/16

0.25 = '/4

0.22 = '/U 0.38 = 3/13

(2) Dimensions in Tables 2 through 9 are common fractions or dimensions from ANSVASME B36.10M, rounded to two-place decimal fractions.

1.6 References

1.6.1 Referenced Standards. Standards and specifications adopted by reference in this Standard are shown in Annex B, which is part of this Standard. It is not considered practical to identify the specific edition of each standard and specification in the individual references. Instead, the specific edition reference is identified in Annex B. A product made in conformance with a prior edition of reference standards and in all other respects conforming to this Standard will be considered to be in conformance.

1.6.2 Codes and Regulations. A fitting used under the jurisdiction of the ASME Boiler and Pressure Vessel Code, the ASME Code for Pressure Piping, or a governmental regulation is subject to any limitation of that code or regulation. This includes any maximum temperature limitation, or rule governing the use of a material at low temperature.

1.7 Service Conditions

Criteria for selection of fitting types and materials suitable for particular fluid service are not within the scope of this Standard.

1.8 Welding

Installation welding requirements are outside the scope of this Standard. Installation welding shall be done in accordance with the applicable piping code or regulation covering the piping system into which the fittings are installed.


ASME B1 6.9-1 993

2 PRESSURE RATINGS

2.1 Basis of Ratings

The allowable pressure ratings for fittings designed in accordance with this Standard may be calculated as for straight seamless pipe of equivalent material (as shown by comparison of composition and mechanical properties in the respective material specifications) in accordance with the rules established in the applicable sections of ASME B3 1, Code for Pressure Piping. For the calculation, applicable data for the NPS, wall thickness (or schedule number), and material equivalent to that of the fitting material shall be used. NPS, wall thickness (or schedule number), and material identity on the fittings are in lieu of pressure rating markings.

2.2 Design of Fittings

The design of fittings shall be established by mathematical analyses contained in nationally recognized pressure vessel or piping codes or at the manufacturer’s option by proof testing in accordance with Section 9 of this Standard. In order to meet design or manufacturing requirements it is expected that some por- tion of formed fittings may have to be thicker than the pipe wall with which the fitting is intended to be used. The mathematical analyses, if used, may take into ac- count such thicker sections. Records of mathematical analysis and/or successful proof test data shall be available at the manufacturer’s facility for inspection by the purchaser.

3 SIZE

The size of fittings in Tables 1 through 9 is identified by the corresponding nominal pipe size ( W S ) as defined in ANSUASME B36.10M.

4 MARKING

4.1 Standard Marking

Each fitting shall be permanently marked to show

(a) manufacturer’s name or trademark; (b) material and product identification (ASTM or

ASME grade symbol). Conformance to this standard is indicated by the prefix “WP” in the grade symbol;

(c) schedule number or nominal wall thickness designation; (d) NPS.

the following:

ASME B L b - S 93 O759670 053L52b T24 m


4.2 Exceptions

Where the size of the fitting does not permit complete marking, the identification marks may be omit- ted in reverse of the order presented above.

4.3 Depth of Stamping

Where steel stamps are used, care shall be taken so that the marking is not deep enough or sharp enough to cause cracks or to reduce the wall thickness of the fitting below the minimum allowed.

4.4 Partial Compliance Fittings

Fittings meeting all requirements of ASTM A 234, A 403, or A 420 except for dimensions, sizes, shapes, or tolerances shall be identified by the marking symbol of the specification followed by the applicable Supplementary Requirement number thereof. Fittings in partial compliance with the requirements of the specification shall not use the marking prefix “WP,” and shall be identified as agreed upon between manufacturer and purchaser.

5 MATERIAL

Wrought fittings covered by this Standard shall be in accordance with ASTM A 234, A403, A420, or the corresponding ASME standard except as provided in para. 1.3. The term wrought denotes fittings made of pipe, tubing, plate, or forgings. Fittings made from block forgings may only be supplied subject to agreement between manufacturer and purchaser. Such fittings need not meet the requirements of Section 7, Surface Contours.

6 FITTINGS DIMENSIONS

6.1 General

This Standard provides for a fixed position for the welding ends with reference to either the center line of the fittings or the overall dimensions. Dimensional standards for these fittings will be found in Tables 2 through 9 and Tables A2 through A9 of Annex A.

6.2 Special Dimensions

For applications where fatigue loading is a concern, required minimum dimensions shall be furnished by the purchaser.

7 SURFACE CONTOURS

Where adjacent openings in fittings are not in paral- lel planes, they shall be joined by a circular arc on the external surfaces. The arc may be terminated in tangents.

8 END PREPARATION

The standard welding bevels and root face are shown in Fig. l . Transitions from the welding bevel to outside surface of the fitting and from the root face to the inside surface of the fitting lying within the maxi- 0 mum envelope shown in Fig. 2 are at the manufacturer’s option except as covered in Note ( 5 ) of Fig. 2 or unless otherwise specifically ordered.

9 DESIGN PROOF TEST

9.1 Required Tests

Proof tests shall be made as set forth herein when the manufacturer chooses proof testing to qualify the fitting design. Unless otherwise agreed upon between manufacturer and purchaser, the only required type of proof test is a bursting strength test.

9.2 Test Assembly

9.2.1 Representative Components. Fittings that are representative of production and selected for test shall be identified as to material, grade, and lot, in- cluding heat treatment. They shall be inspected for dimensional compliance to this Standard.

9.2.2 Other Components. Straight seamless or welded pipe sections whose calculated bursting strength is at least as great as the proof test pressure as calculated in para. 9.3 shall be welded to each end of 0 the fitting to be tested. Any internal misalignment greater than 0.06 in. (1.6 mm) shall be reduced by taper boring at a slope not over 1:3: Length of pipe sections for closures shall be as follows.

(a) Minimum length of pipe shall be one pipe O.D. for NPS 14 and smaller.

(b) Minimum length of pipe shall be one-half pipe O.D. for NPS greater than 14 in.

9.3 Test Procedure

Test fluid shall be water or other liquid used for hydrostatic testing. Hydrostatic pressure shall be applied to the assembly. The test is successful if the assembly

ASME 616.9-1993

withstands, without rupture, 105% of the computed proof test pressure defined below.

2 st p = - D

where P = computed proof of test pressure S = actual tensile strength of the test fitting, de-

termined on a specimen representative of the test fitting, which shall meet the tensile strength requirements of the applicable material of para. 5.0

t = nominal pipe wall thickness of the pipe that the fitting marking identifies

D = specified outside diameter of pipe

9.4 Applicability of Test Results

It is not necessary to conduct an individual test of fittings with all combinations of sizes, wall thick- nesses, and materials. A successful proof test on one representative fitting may represent others to the ex- tent described herein.

9.4.1 Size Range. One test fitting may be used to qualify similarly proportioned fittings with an NPS range from one-half to twice that for the tested fitting. The test of a non-reducing fitting qualifies reducing fittings of the same pattern. The test of a reducing fitting qualifies reductions to smaller sizes.

9.4.2 Thickness Range. One test fitting may be used to qualify similarly proportioned fittings with t / D ranges from one-half to three times that for the tested fitting.

9.4.3 Material Grades. The pressure retaining ca- ,

pacity of a geometrically identical fitting made of various grades of steel will be directly proportional to the tensile properties of the various grades. Therefore, it is necessary to test only a single material grade in a representative fitting to prove the design of the fitting.

1 O PRODUCTION TESTS

Hydrostatic testing of wrought fittings is not required by this Standard. All fittings shall be capable of withstanding, without leakage or impairment of serv- iceability, a hydrostatic test pressure required by the applicable piping code for seamless pipe of material equivalent to the fitting material and of the NPS and wall thickness the fitting marking identifies.

11 TOLERANCES

Tolerances for fittings are shown in Tables 1 and Al, and apply to the nominal dimensions given in Ta- bles 2 through 9 and A2 through A9. Where given in the tables, the minimum and maximum dimensions are based on these tolerances. The listings with decimals do not imply precision measurement such as use of vernier, micrometer, electronic readout equipment, etc.

GENERAL NOTES: (a) Dimensions are in inches. (bl See Table 1 for tolerances.

NOTES: (1 The lap thickness T shall not be less than nominal pipe wall thickness. (2) When short pattern stub ends are used with larger flanges in Classes 300 and 600, and with most

sizes in Classes 900 and higher, and when long pattern stub ends are used with larger flanges in Classes 1500 and 2500, it may be necessary to increase the length of the stub ends in order to avoid covering the weld with the flange. Such increases in length shall be a matter of agreement between the manufacturer and the purchaser.

(3) When special facings such as tongue and groove, male and female, etc., are employed, additional lap thickness must be provided and such additional thickness shall be in addition to (not included in) the basic length F.

(4) These dimensions conform to the radius established for lap joint flanges in ASME/ANSI 816.5. Pipe Flanges and Flanged Fittings.

(5) This dimension conforms to standard machine facings shown in ASME/ANSI B16.5. The back face of the lap shall be machined to conform to the surface on which it seats. Where ring joint facings are to be applied use dimension Kas given in ASME/ANSI B1 6.5.

(6) Gasket face finish shall be in accordance with ASME/ANSI B16.5 for raised face flanges. (7) The long pattern shall be the standard when not specified by the purchaser. The short pattern

shall be specified by the purchaser.

ANNEX A

METRIC (SI) TABLES

(This Annex is an integral part of ASME 816.9-1993 and is placed after the main text for convenience.)

ASME B1 6.9-1 993

O The technique of rounding the metric conversions of the inch dimensions recognized two basic categories of dimensions occurring in this Standard, based upon the function or safety significance of variations in the dimensions.

Where-some slight shift of the absolute value of the minimum and maximum dimensions permitted by the inch dimensions and those provided by the converted metric dimensions do not unacceptably affect the functional or safety characteristics of the fitting, the metric conversions have been rounded to whole millimeter values in order to facilitate ease of measurement by ordinary measuring tapes or rulers with nonmagnified vision. Furthermore, the rounding has not always been made to the nearest whole millimeter. In some cases it has been made to the whole millimeter, which would facilitate tables manifesting logical incre- ments in both the dimensions and their tolerances. It is recognized that the introduction of such variances will create a conflict in the acceptance dimensions or gaging between the inch and metric data. Experience indicates a probability that no serious difficulties will result from this conflict. Hence it is the intent of this Standard that any dimension that is within tolerance by either metric or inch measurement is considered to be in conformance with this Standard.

Where it was considered advisable to limit the variance between the minimum and maximum dimensions permitted by the existing tolerances and those permitted by the converted metric dimensions, closer rounding was utilized.

The metric dimensions shown in Tables Al through A9 are for information and reference. They are not exact equivalents of the dimensions in Tables 1 through 9. If used by agreement between manufacturer and purchaser, complete dimensional interchangeability with standard components cannot be assured. Use of a combination of standard and metric values is contrary to the intent of this Standard.

NOTES TO TABLE A7

ASME 816.9-1993

GENERAL NOTES: (a) Dimensions are in millimeters. (b) See Table A l for tolerances.

NOTES: (1 The lap thickness Tshall not be less than nominal pipe wall thickness. (2) When short pattern stub ends are used with larger flanges in Classes 300 and 600, and with most sizes in Classes 900 and higher,

and when long pattern stub ends are used with largerflanges in Classes 1500 and 2500, it may be necessary to increase the length of the stub ends in order to avoid covering the weld with the flange. Such increases in length shall be a matter of agreement between the manufacturer and purchaser.

(3) When special facings such as tongue and groove, male and female, etc., are employed, additional lap thickness must be provided and such additional thickness shall be in addition to (not included in) the basic length F.

(4) These dimensions conform to the radius established for lap joint flanges in ASME/ANSI B1 6.5, Pipe Flanges and Flanged Fittings. (5) This dimension conforms to standard machined facings shown in ASME/ANSI B1 6.5. The back face of the lap shall be machined to

conform to the surface on which it seats. Where ring joint facings are to be applied, use dimension Kas given in ASME/ANSI B I 6.5. (6) Gasket face finish shall be in accordance with ASME/ANSI B16.5 for raised face flanges. ( 7 ) The long pattern shall be the standard when not specified by the purchaser. The short pattern shall be specified by the purchaser.
