FOREWORD
In March1927,the American Standards Association authorized the organization of a Sectional Committee on Standardization of Dimensions and Material of Wrought Steel and Wrought Iron Pipe and Tubing for the purpo of unifying the standards of the commodities in force in this country.The American Society for Testing and Materials and The American Society of Mechanical Engineers were designated as sponsors,and the first meeting of the Sectional Committee was held in Pittsburgh,Pennsylvania,on May18,1928.
The dimensions of commercial pipe in general u in the United States at the time conformed rather generally to tho recommended by the ASME Committee on Standard Pipe and Pipe Threads published in1886(ASME Transactions,Vol.VIII,p.29).On the standards an enormous industry has b
een built and the satisfactory u of this product proves the soundness of the original design and specification.
Increasingly vere rvice demands at the time of the Committee’s organization had been met by using the nearest available pipe or tubing for heavier ctions such as casing,mechanical tubing,etc.,with resulting uneconomical multiplicity of wall thickness.
Subquently,the Committee,with the cooperation of the industry,made a survey of existing practice as the logical starting point for the development of an American Standard.From this survey,a table was designed to provide a lection of wall thickness of pipe to cover the power piping requirements of industry where strength to resist internal pressure governs lection and was later expanded to include pipe diameters and thickness ud in other industries.
The original intent of the Committee was to establish a system of Schedule Numbers for pipe size/wall thickness combinations which would have an approximately uniform relationship equal to1000times the P/S expression contained in the modified Barlow formula for pipe wall thickness as defined in the Appendix to this standard.The resulting Numbers departed so far from existing wall thickness in common u that the original intent could not be accomplished.The Schedule Numbers were then adopted strictly as a convenient designation system for u in ordering.
In all cas,the designer must ba his lection on the rules and allowable stress t by the code which governs his particular construction.The table is dimensionally complete for all sizes and wall thickness within its scope,but some of the larger,heavier wall ctions are beyond the capability of amless mill production and must be obtained from forged and bored billets or other sources.
我喜欢的一种植物The first issue of this standard was given with the designation American Standard“tentative”by the American Standards Association in November1935.Subquent slight revisions to Table 1and the footnotes of the dimensional tables were approved and the ASA changed the designation to American Standard;the date of ASA approval was April28,1939.
Further revisions were made by the Sectional Committee.The list of specifications in Table1 was revid where necessary and slight revisions in wall thickness of some of the large sizes of the heavy schedules were made where P/S values were out of line.
It was the hope in1939that the designation of pipe ud commercially by all industry as Standard weight,Extra-Strong,and Double Extra-Strong would gradually be replaced by Schedule Number designation.However,owing to customs of over50years’standing,demand and produc-tion of pipe to the traditional dimensions is undiminished.Conquently,in respon to a demand from urs,acc
epted practice for dimensions and weights of commercial wrought steel and welded wrought iron pipe were added.The changes were designated an American Standard on February23,1950.
Subcommittee No.1was reorganized in1957.In addition to necessary editorial changes,a simplified format was lected for the tables of weights and dimensions so as to include and identify the sizes and weights of API Standards5L and5LX.The changes to the standard were approved and it was designated an American Standard on December21,1959.
The standard was revid in1969.A uniform method to calculate the plain end weight of steel pipe was included,and minor adjustments were made in the tabulated weights of steel pipe in
iv
Table2to conform to this new method.Additional sizes and thickness of steel pipe that had come into common u were also added to Table2.Inasmuch as API Standard5L no longer included wrought iron pipe,reference to this API Standard was deleted from Table3.The changes to the standard were approved and it was designated an American National Standard on February3,1970.
Further revisions were made to the standard in1975.Additional sizes and thickness of steel pipe th
at had been added to API specifications were added to Table2.Table3,Dimensions and Weights of Welded Wrought Iron Pipe,was deleted in its entirety,since wrought iron pipe is no longer produced.The changes in the standard were approved and it was designated an American National Standard on June5,1975.
The standard was revid in1978to include SI metric dimensions.The outside diameter and wall thickness were converted to millimeters by multiplying the inch dimensions by25.4. Outside diameters larger than16in.were rounded to the nearest millimeter,and outside diameters 16in.and smaller were rounded to the nearest0.1mm.Wall thickness were rounded to the nearest0.01mm.The converted and rounded SI metric dimensions were added to Table2.A formula to calculate the SI metric plain end mass,in kilograms per meter,using SI metric diameters and thickness was added to ction5.The SI metric plain end mass was calculated and was added to Table2.The changes in the standard were approved and it was designated an American National Standard on July18,1979.
Further revisions were made in1984.The ANSI designations,which are no longer in u,were deleted from Table1,and the list of specifications was revid to agree with current ASTM and API specifications.Additional sizes and thickness which had been added to API specifications were ad
ded to Table2.That edition was approved as an American National Standard on August 19,1985.狂人日记主要内容>清贫的反义词
The next edition included additional wall thickness and was approved by the American National Standards Institute on August24,1995.

The1996edition contained revisions to Table2,adding pipe sizes,changing some plain end weights and mass,identifying metric pipe by the dimensionless designator DN,and eliminating the API Specification column.The1996edition was approved as an American National Standard on September23,1996.
The2000edition contained revisions to Table2to include the revid density for steel incorpo-rated into Section5previously.Table1was deleted and other editorial changes to Sections1,2, 3,5,8,and9were made.The2000edition was approved as an American National Standard on December1,2000.
The current edition contains revisions to Section5and Table1.It corrects the equation for nominal plain end weight.It adds the missing DN schedule numbers in Table1.This edition was approved as an American National Standard on June23,2004.
