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 coseeretariat 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 ap- proved by the Committee, cosponsors, and ASA, and published with the designation ASA. B16.9-1940. Revisions were made in 1950 and 1955 to add sizes upto 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 clarity 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 % and 4). 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 (USASH, then as the American National Standards Institute (ANSD, with the Sectional Committee being redesignated as an American National Standards Committee, another re~ vision increasing the size range to NPS 48 and revising the text for clarity was approved and published as ANSI BI6.9-197L 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 ¥ 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, BL6.9a- 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 mad 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 Bast 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 B16 COMMITTEE Standardization of Valves, Flanges, Fittings, and Gaskets (The following ls th ros of the Committaa at the time of approval ofthis Standard.)

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 fit- tings meet all other stipulations of this Standard, they shall be considered as being in partial compliance therewith, provided they are appropriately marked. (ee 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, 1.8 Standard Units ‘The inch is the standard unit for linear dimensions. Values in millimeters are for information and refer- ence only. See Annex A. Notes: ) Tolerance valuss shown in Tab | in decimal inches aro com mon fractions rounded #8 follows 0.03 = Ya 0.06 = vie 0.409 = 022 = 7 025 = (2) Dimensions in Tables 2 through 9 are common fractions or di- ‘mensions from ANSI/ASME B36.10M, rounded to two-place ‘decimal fractions 1.6 References 1.6.1 Referenced Standards. Standards and spec- ifications adopted by reference in this Standard are shown in Annex B, which is part of this Standard. [tis ‘not considered practical to identify the speciticedition of each standard and specification in the individual references. Instead, the specific edition reference is identified in Annex B. A product made in conform- ance 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 un- dec the jurisdiction of the ASME Boiler and Pressure Vessel Code, the ASME Code for Pressure Piping, of a governmental regulation is subject ro any limitation of that code or cegulation, This includes any maxi- ‘mum 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 B16.9-1993 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 B31, Code for Pressure Piping. For the calculation, applicable data for the NPS. wall thickness (or schedule number), and material equiva- lent to that of the fitting material shall be used. NPS, wall thickness (or schedule number), and material identity on the fittings are in liew of pressure rating markings. 2.2 Design of Fittings ‘The design of fittings shall be established by mathe- matical analyses contained in nationally recognized pressure vessel or piping codes or at the manufactur- ‘e's option by proof testing in accordance with Section 9 of this Standard, In order to meet design or manu: facturing 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 analysig 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 | through 9 is identified. by the corresponding nominal pipe size (NPS) as de- fined in ANSI/ASME B36.10M. 4 MARKING 4.1. Standard Marking Fach fitting shall be permanently marked to show the following: (@) 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; (©) schedule number or nominal wall thickness des- ignation; (d) NPS. FACTORY-MADE WROUGHT STEEL BUTTWELDING FITTINGS: 4.2 Exceptions Where the size of the fitting does not permit com- plete 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 oF 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, A403, or A 420 except for dimensions, sizes, shapes, or tolerances shall be identified by the marking sym- bol 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 manu facturer and purchaser. 5 MATERIAL Wrought fittings covered by this Standard shall be in accordance with ASTM A 234, A 403, A 420, 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 agree ‘ment between manufacturer and purchaser. Such fit- tings 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.FACTORY. MADE WROUGHT STEEL BUTTWELDING FITTINGS. 7 SURFACE CONTOURS Where adjacent openings in fittings are not in paral fel 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. 1. 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- mum envelope shown in Fig. 2 are at the manufactur- er’s option except as covered in Note (5) of Fig. 2 of 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 di- ‘mensional compliance to this Standard. 9.2.2 Other Components. Straight seamless or welded pipe sections whose calculated bursting strength isat feast as great as the proof test pressure as calculated in para. 9.3 shall be welded to each end of 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. (2) Minimum length of pipe shall be one pipe 0.D. for NPS 14 and smaller. (®) Minimum length of pipe shall be one-talf pipe ©.D. for NPS greater than 14 in, 9.3 Test Procedure ‘Test fluid shall be water o other liquid used for hy- drostatic testing. Hydrostatic pressure shall be applied. to the assembly. The test is successful if the assembly ASME 816.9-1993, withstands, without rupture, 105% of the computed proof test pressure defined below. 2st Petoe where ‘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 ma- terial of para. 5.0 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 fit- ting qualifies reductions to smaller sizes. 9.4.2 Thickness Range. One test fitting may be used to qualify similarly proportioned fittings with 1/D ranges fcom 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 vari- us grades of steel will be directly proportional to the tensile properties of the various grades. Therefore, it is necessary to test only asingle material gradein a rep- resentative fitting to prove the design of the fitting, 10 PRODUCTION TESTS Hydrostatic testing of wrought fittings is not re- quired 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 mnarking identifies.ASME B16.9-1993 FACTORY-MADE WROUGHT STEEL BUTTWELDING FITTINGS, 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.

ASME 816,9-1993. ANNEX A. METRIC (SI) TABLES [This Annox is an integral part of ASME B16,9-1893 and is placed after the main text for convaniones-) ‘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 ofthe fitting, the metric con- versions have been rounded to whole millimeter values in order to facilitate ease of measure- ment 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. Iti recogaized that the introduction of such variances will create a conflict ia 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 itis 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 maxi- ‘mum dimensions permitted by the existing tolerances and those permitted by the converted metric dimensions, closer rounding was utilized. ‘The metric dimensions showa in Tables Al through A9 are for information and refer- ence, They are not exact equivalents of the dimensions in Tables 1 through 9. If used by agreement between manufacturer and purchaser, complete dimensional interctangeability with standard components cannot be assured. Use of a combination of standard and metric values is contrary to the intent of this Standard. 1FACTORY.

The procedure for requesting an interpretation is described in the follow- ing paragraphs. ‘The interpretations include all replies which have been approved by the BI6 Main Committee in, response to inquiries concerning interpretation of this Standard, ‘An interpretation applies either to the Edition and Addenda in effect on the date of issuance of the interpretation or the Edition and Addenda stated in the interpretation. Subsequent revisions to this ‘Standard may supersede the interpretation. PROCEDURE FOR REQUESTING INTERPRETATIONS On request, the B16 Committee will render an interpretation of any requirement of this Standard Interpretations can only be rendered in response to a written request, which should be addressed to: Secretary, B16 Main Committee ‘The American Society of Mechanical Engincers United Engineering Center 345 East 47th Street New York, NY 10017 ‘The request for interpretation should be clear and unambiguous. It is further recommended that the inquiger submit his request using the following format: fa) Subject. Cite the applicable paragraph number(s) and/or give a concise description of the subject, () Question, Phrase the question as a request for an interpretation of a specific requirement suitable for general understanding and use, not as a request for an approval of a proprietary design or situation. The inquirer may also include any plans or drawings which are necessary to explain the question; however, they should not contain proprietary names or information. ‘Requests which are not in this format may be rewritten in this format prior to being answered, which may inadvertently change the original intent of the request "ASME procedutes provide for reconsideration of an interpretation when or if additional informa- tion is available which the inquirer believes might affect the interpreration. Further, persons aggrieved by an interpretation may appeal to the cognizant ASME committee or subcommittee.
