13、e and Tubing for the purpose of unifying the standards of these commodities in force in thiscountry. The American Society for Testing and Materials and The American Society of MechanicalEngineers were designated as sponsors, and the first meeting of the Sectional Committee washeld in Pittsburgh, Pen
14、nsylvania, on May 18, 1928.The dimensions of commercial pipe in general use in the United States at the time conformedrather generally to those recommended by the ASME Committee on Standard Pipe and PipeThreads published in 1886 (ASME Transactions, Vol. VIII, p. 29). On these standards an enormousin
15、dustry has been built and the satisfactory use of this product proves the soundness of theoriginal design and specification.Increasingly severe service demands at the time of the Committees organization had been metby using the nearest available pipe or tubing for heavier sections such as casing, me
16、chanicaltubing, etc., with resulting uneconomical multiplicity of wall thicknesses.Subsequently, the Committee, with the cooperation of the industry, made a survey of existingpractice as the logical starting point for the development of an American Standard. From thissurvey, a table was designed to
17、provide a selection of wall thicknesses of pipe to cover the powerpiping requirements of industry where strength to resist internal pressure governs selection andwas later expanded to include pipe diameters and thicknesses used in other industries.The original intent of the Committee was to establis
18、h a system of Schedule Numbers for pipesize/wallthicknesscombinationswhichwouldhaveanapproximatelyuniformrelationshipequalto 1000 times the P/S expression contained in the modified Barlow formula for pipe wall thicknessas definedin theAppendix* to thisstandard. Theresulting Numbers departedso farfro
19、m existingwall thicknesses in common use that the original intent could not be accomplished. The ScheduleNumbers were then adopted strictly as a convenient designation system for use in ordering.In all cases, the designer must base his selection on the rules and allowable stresses set by thecode whi
20、ch governs his particular construction. The table is dimensionally complete for all sizesand wall thicknesses within its scope, but some of the larger, heavier wall sections are beyondthe capability of seamless mill production and must be obtained from forged and bored billetsor other sources.The fi
21、rst issue of this standard was given with the designation American Standard “tentative”by the American Standards Association in November 1935. Subsequent slight revisions to Table 1and the footnotes of the dimensional tables were approved and the ASA changed the designationto American Standard; the
22、date of ASA approval was April 28, 1939.Further revisions were made by the Sectional Committee. The list of specifications in Table 1was revised where necessary and slight revisions in wall thicknesses of some of the large sizesof the heavy schedules were made where P/S values were out of line.It wa
23、s the hope in 1939 that the designation of pipe used commercially by all industry asStandardweight,Extra-Strong,andDoubleExtra-StrongwouldgraduallybereplacedbyScheduleNumberdesignation.However,owingtocustomsofover50yearsstanding,demandandproduc-tion of pipe to these traditional dimensions is undimin
24、ished. Consequently, in response to ademand from users, accepted practice for dimensions and weights of commercial wrought steelandweldedwroughtironpipewereadded.ThesechangesweredesignatedanAmericanStandardon February 23, 1950.* This Appendix, which appeared in the 1975 edition, was later removed.iv
25、Subcommittee No. 1 was reorganized in 1957. In addition to necessary editorial changes, asimplified format was selected for the tables of weights and dimensions so as to include andidentify the sizes and weights of API Standards 5L and 5LX. These changes to the standard wereapproved and it was desig
26、nated an American Standard on December 21, 1959.The standard was revised in 1969. A uniform method to calculate the plain end weight of steelpipe was included, and minor adjustments were made in the tabulated weights of steel pipe inTable 2 to conform to this new method. Additional sizes and thickne
27、sses of steel pipe that hadcome into common use were also added to Table 2. Inasmuch as API Standard 5L no longerincluded wrought iron pipe, reference to this API Standard was deleted from Table 3. Thesechanges to the standard were approved and it was designated an American National Standardon Febru
28、ary 3, 1970.Further revisions were made to the standard in 1975. Additional sizes and thicknesses of steelpipe that had been added to API specifications were added to Table 2. Table 3, Dimensions andWeights of Welded Wrought Iron Pipe, was deleted in its entirety, since wrought iron pipe is nolonger
29、produced.ThesechangesinthestandardwereapprovedanditwasdesignatedanAmericanNational Standard on June 5, 1975.The standard was revised in 1978 to include SI metric dimensions. The outside diameter andwall thicknesses were converted to millimeters by multiplying the inch dimensions by 25.4.Outsidediame

These converted and rounded SI metric dimensions were added to Table 2. AformulatocalculatetheSImetricplainendmass,inkil

The SI metric plain end mass was calculated and wasaddedtoTable2.ThesechangesinthestandardwereapprovedanditwasdesignatedanAmericanNational Standard on July 18, 1979.Further revisions were made in 1984. The ANSI designations
32、, which are no longer in use, weredeleted from Table 1, and the list of specifications was revised to agree with current ASTM andAPI specifications. Additional sizes and thicknesses which had been added to API specificationswere added to Table 2. That edition was approved as an American National Sta
33、ndard onAugust 19, 1985.The next edition included additional wall thicknesses and was approved by the AmericanNational Standards Institute on August 24, 1995.The 1996 edition contained revisions to Table 2, adding pipe sizes, changing some plain endweightsand masses,identifyingmetric pipebythe dimen

The 1996 edition was approved as an American National Standardon September 23, 1996.The 2000 edition contained revisions to Table 2 to include the revised density for steel incorpo-rated into section 5 previously. Table 1 was deleted
35、and other editorial changes to Sections 1, 2,3, 5, 8, and 9 were made. The 2000 edition was approved as an American National Standard onDecember 1, 2000.The 2004 edition contained revisions to section 5 and Table 1. It corrected the equation fornominal plain end weight. It added the missing DN sched

48、res and pressures.The word pipe is used, as distinguished from tube,toapply to tubular products of dimensions commonly usedfor pipeline and piping systems. Pipe NPS 12 (DN 300)and smaller have outside diameters numerically largerthan their corresponding sizes. In contrast, the outsidediameters of tu
49、bes are numerically identical to the sizenumber for all sizes.2 SIZEThe size of all pipe is identified by the nominalpipe size.The manufacture of pipe NPS18(DN 6) to NPS 12(DN 300), inclusive, is based on a standardized outsidediameter (O.D.). This O.D. was originally selected sothat pipe with a standard O.D. and having a wall thick-ness that was typical of the period would have an insidediameter (I.D.) approximately equal to the nominal size.Although there is no such relation between the existingstandard thickness O.D. and nominal size thesenominal sizes and stan
