14、velop standards for pipeflanges and fittings. Cosponsors of the B16 Committee were The American Society of MechanicalEngineers (ASME), the Heating and Piping Contractors National Association now MechanicalContractors Association of America (MCAA), and the Manufacturers Standardization Societyof the

15、Valve and Fitting Industry (MSS). Cosponsors were later designated as Co-Secretariatorganizations.Threaded fittings were also included in the scope of the B16 Committee, and Subcommittee 2(now Subcommittee B) was made responsible for threaded fittings other than steel.The American Standard for Pipe

16、Plugs was originally published as ASA B16e2-1936. It hadbeen developed by Subcommittee 2 from material assembled and published by MSS as a standardpractice in April 1929.From the beginning, pipe plugs have been made with the American Standard Taper Pipe Threadbut the design of the square heads neces

17、sary to screw them into fittings or any tapped hole hasbeen a matter of manufacturers and users individual design. However, the use of pipe plugs soonbroadened, and they came to be employed in many other service applications, e.g., automotive andindustrial machinery. Accordingly, it was natural for

18、the dimensions of the square heads and thesockets to conform to standard open wrench sizes and to maximum dimensions of standard hot-rolled steel bars.Pipe bushing and locknut dimensions were originally included in ASA B16c-1939, AmericanStandard for 150 lb Malleable Iron Screwed Fittings. ASA B16c-

19、1939 was adapted from informationassembled and published by MSS in 1929.In response to a demand for inclusion under one cover, B16.14-1943, American Standardfor Ferrous Plugs, Bushings, Locknuts, and Caps, was developed from ASA B16c-1939 andASA B16d-1941, American Standard for Cast Iron Screwed Fit

20、tings, 125 lb and 250 lb, andapproved by ASA in October 1943. The section of B16.14 covering pipe caps was later removedbecause of differences in pressure ratings between caps made of cast iron and malleable iron.This Standard was revised in 1948 and was approved by letter ballot vote of the Section

21、alCommittee and, following the approval of the sponsor bodies, it was presented to ASA, now theAmerican National Standards Institute (ANSI), with recommendations for approval as anAmerican Standard. This approval and designation was given on April 6, 1949.Subcommittee 2 began a review of the documen

22、t in 1963 and completed its work in 1964. TheSectional Committee approved a number of minor changes in format and wording. Followingapproval by the sponsor organizations, ANSI approval was granted on November 12, 1965.In 1970, a review was initiated by Subcommittee 2 that resulted in the proposal to

23、 revise thedocument in several minor areas and update referenced standards. Following approvals by theStandards Committee and Co-Secretariat, ANSI granted approval on November 1, 1971.In 1975, review was again initiated by Subcommittee B (formerly Subcommittee 2), and it wasdetermined that the only

24、significant changes needed were the updating of referenced standardsand the addition of metric equivalents. Approvals were granted by the Standards Committee,Co-Secretariat, and ANSI, the latter on February 4, 1977.In 1982, the American National Standards Committee was reorganized as an ASME Committ

25、eeoperating under procedures accredited by ANSI. That same year, Subcommittee B once againbegan review of the Standard. The only changes made were the dates of the referenced standards.After approval by the Standards Committee and ASME, final approval was granted by ANSI inJuly 1983.In the 1991 edit

26、ion of B16.14, U.S. customary units were established as the standard and updateswere made to the referenced standards and minimum specifications for steel fittings. Followingapproval by the Standards Committee and ASME, approval as an American National Standardwas given by ANSI on January 4, 1991, w

27、ith the new designation ASME B16.14-1991.ivIn the 2010 edition of B16.14, metric dimensions became the primary units, and inch dimensionswere incorporated into the Standard as secondary units and shown in parentheses. Followingapproval by the Standards Committee and the ASME Board, the revision to t

28、he 1991 edition ofthe Standard was approved as an American National Standard by ANSI on April 1, 2010, anddesignated as ASME B16.14-2010.In this 2013 edition, section 8 was revised and now requires threads and gaging practices tobe as per, and identical with, ASME B1.20.1 and other B16 standards. Fo

29、llowing approval by theASME B16 Standards Committee, approval as an American National Standard was given byANSI on July 29, 2013, with the new designation ASME B16.14-2013.vASME B16 COMMITTEEStandardization of Valves, Flanges, Fittings, and Gaskets(The following is the roster of the Committee at the

36、dopted by reference areshown in Mandatory Appendix II. It is not consideredpractical to identify the edition of each referenced stan-dard and specification in the text. Instead, the editionsof the referenced standards and specifications are listedin Mandatory Appendix II.2.2 Quality SystemsRequireme

37、nts relating to the product manufacturersquality system programs are described inNonmandatory Appendix A.2.3 Relevant UnitsThis Standard states values in both SI (Metric) unitsand U.S. Customary units. These systems of units areto be regarded separately as standard. Within the text,the U.S. Customar

38、y units are shown in parentheses orin separate tables that appear in Mandatory Appendix I.The values stated in each system are not exact equiva-lents; therefore, it is required that each system of unitsbe used independently of the other. Combining valuesfrom the two systems constitutes nonconformanc

39、e withthe Standard.2.4 Service ConditionsCriteria for selection of materials suitable for particu-lar fluid service are not within the scope of this Standard.2.5 ConventionFor determining conformance with this Standard, theconvention for fixing significant digits where limits(maximum and minimum val

40、ues) are specified shall be1as defined in ASTM E29. This requires that an observedor calculated value be rounded off to the nearest unitin the last right-hand digit used for expressing the limit.Decimal values and tolerances do not imply a particularmethod of measurement.2.6 Denotation2.6.1 Pressure

41、 Rating Designation. Class followedby a dimensionless number is the designation forpressuretemperature ratings.2.6.2 Size. Nominal pipe size (NPS) followed by adimensionless number is the designation for nominalflange or flange fitting size. NPS is related to the refer-ence nominal diameter, DN, use

42、d in international stan-dards. The relationship is, typically, as follows:NPS DN12511432112402502126538312904 100For NPS 4, the related DN p 25 H11547 (NPS)3 PRESSURETEMPERATURE RATINGS(a) Pressuretemperature ratings for plugs and bush-ings shall be in accordance with ASME B16.4 if madeof cast iron,

43、 or ASME B16.3 if made of malleable iron,ductile iron, or steel. Use of cored plugs or hexagonhead bushings should be limited to Class 125 cast ironand Class 150 malleable iron threaded fittings. Solidplugs and face bushings are recommended for use withClass 250 cast iron fittings and Class 300 mall

44、eable ironfittings.(b) Locknuts are not pressuretemperature rated.4 NOMINAL PIPE SIZEAs applied in this Standard, the use of the phrase“nominal pipe size” or the designation NPS followedby a dimensionless number is for identifying the endconnection of fittings. The number is not necessarily thesame

45、as the fitting inside diameter.(13)ASME B16.14-20135 MARKINGEach fitting shall be marked for identification withthe manufacturers name or trademark, except where amarking is impractical.6 MATERIALS(a) These fittings are furnished in gray iron, malleableiron, ductile iron, or steel as indicated in th

46、e individualtables.(b) The chemical and mechanical properties of castmaterial shall equal or exceed those properties listed inASTM A126, as applicable. Steel castings, forgings, ormachined bar properties shall correspond to the compa-rable ASTM casting material specifications. The fittingsmanufactur

47、er shall be prepared to certify conformancebased on test data.7 DIMENSIONS AND TOLERANCES(a) Dimensions in metric units are given in Tables 1through 5 for various types of fittings. CorrespondingU.S. Customary values are given in Tables I-1 throughI-5 in Mandatory Appendix I.(b) At no point in the c

48、omponent wall shall the metalthickness be less than 90% of the values listed in thetables.8 THREADS8.1 Thread FormAll threads shall be in accordance with ASME B1.20.1.8.1.1 Countersinks and Chamfers. All internal taperpipe threads shall be countersunk or chamfered a dis-tance of not less than one-ha

49、lf the pitch of the threadat an angle of approximately 45 deg with the axis of thethread. External taper pipe threads shall be chamferedat an angle between 30 deg and 45 deg with the axis,2for easier entrance in making a joint and protection ofthe thread. Countersinking and chamfering shall be con-centric with the threads. The length of threads specifiedin all tables shall be measured to include the countersinkor chamfer.8.1.2 Alignment. The maximum allowable variationin the alignment of threads of all openings shall be5.0 mm/m (0.06 in./ft).8.1.3 Internal Threadin
