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 been 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.
The first issue of this standard was given with the designation American Standard“tentative”by the A
merican 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.
天蝎座和双子座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,accepted 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
