Wall Thickness Selection Table Dimensions and Weights of Welded and Seamless Wrought Steel Pipe iii FOREWORD In March 1927, 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 purpose of unifying the standards of these 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 May 18, 1928 The dimensions of commercial pipe in general use in the United States at the time conformed rather generally to those recommended by the ASME Committee on Standard Pipe and Pipe Threads published in 1886 (ASME Transactions, Vol VIII, p 29) On these standards an enormous industry has been built and the satisfactory use of this product proves the soundness of the original design and specification Increasingly severe service demands at the time of the Committee’s organization had been met by using the nearest available pipe or tubing for heavier sections such as casing, mechanical tubing, etc., with resulting uneconomical multiplicity of wall thicknesses Subsequently, 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 selection of wall thicknesses of pipe to cover the power piping requirements of industry where strength to resist internal pressure governs selection and was later expanded to include pipe diameters and thicknesses used 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 to 1000 times 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 thicknesses in common use that the original intent could not be accomplished The Schedule Numbers 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 the code which governs his particular construction The table is dimensionally complete for all sizes and wall thicknesses within its scope, but some of the larger, heavier wall sections are beyond the capability of seamless 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 American Standards Association in November 1935 Subsequent slight revisions to Table and the footnotes of the dimensional tables were approved and the ASA changed the designation to American Standard; the date of ASA approval was April 28, 1939 Further revisions were made by the Sectional Committee The list of specifications in Table was revised where necessary and slight revisions in wall thicknesses of some of the large sizes of the heavy schedules were made where P/S values were out of line It was the hope in 1939 that the designation of pipe used 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 over 50 years’ standing, demand and production of pipe to these traditional dimensions is undiminished Consequently, in response to a demand from users, accepted practice for dimensions and weights of commercial wrought steel and welded wrought iron pipe were added These changes were designated an American Standard on February 23, 1950 * This Appendix, which appeared in the 1975 edition, was later removed iv Subcommittee No was reorganized in 1957 In addition to necessary editorial changes, a simplified format was selected for the tables of weights and dimensions so as to include and identify the sizes and weights of API Standards 5L and 5LX These changes to the standard were approved and it was designated an American Standard on December 21, 1959 The standard was revised in 1969 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 Table to conform to this new method Additional sizes and thicknesses of steel pipe that had come into common use were also added to Table Inasmuch as API Standard 5L no longer included wrought iron pipe, reference to this API Standard was deleted from Table These changes to the standard were approved and it was designated an American National Standard on February 3, 1970 Further revisions were made to the standard in 1975 Additional sizes and thicknesses of steel pipe that had been added to API specifications were added to Table Table 3, Dimensions and Weights of Welded Wrought Iron Pipe, was deleted in its entirety, since wrought iron pipe is no longer produced These changes in the standard were approved and it was designated an American National Standard on June 5, 1975 The standard was revised in 1978 to include SI metric dimensions The outside diameter and wall thicknesses were converted to millimeters by multiplying the inch dimensions by 25.4 Outside diameters larger than 16 in were rounded to the nearest millimeter, and outside diameters 16 in and smaller were rounded to the nearest 0.1 mm Wall thicknesses were rounded to the nearest 0.01 mm These converted and rounded SI metric dimensions were added to Table A formula to calculate the SI metric plain end mass, in kilograms per meter, using SI metric diameters and thicknesses was added to section The SI metric plain end mass was calculated and was added to Table These changes in the standard were approved and it was designated an American National Standard on July 18, 1979 Further revisions were made in 1984 The ANSI designations, which are no longer in use, were deleted from Table 1, and the list of specifications was revised to agree with current ASTM and API specifications Additional sizes and thicknesses which had been added to API specifications were added to Table That edition was approved as an American National Standard on August 19, 1985 The next edition included additional wall thicknesses and was approved by the American National Standards Institute on August 24, 1995 The 1996 edition contained revisions to Table 2, adding pipe sizes, changing some plain end weights and masses, identifying metric pipe by the dimensionless designator DN, and eliminating the API Specification column The 1996 edition was approved as an American National Standard on September 23, 1996 The 2000 edition contained revisions to Table to include the revised density for steel incorporated into section previously Table was deleted and other editorial changes to Sections 1, 2, 3, 5, 8, and were made The 2000 edition was approved as an American National Standard on December 1, 2000 The 2004 edition contained revisions to section and Table It corrected the equation for nominal plain end weight It added the missing DN schedule numbers in Table This edition was approved as an American National Standard on June 23, 2004 The 2015 edition contains revisions to Table by removing Note (3) and its references The 2015 edition was approved as an American National Standard on June 16, 2015 v ASME B32 COMMITTEE Metal and Metal Alloy Wrought Mill Product Nominal Sizes (The following is the roster of

This O.D was originally selected so that pipe with a standard O.D and having a wall thickness that was typical of the period would have an inside diameter (I.D.) approximately equal to the nominal size Although there is no such relation between the existing standard thickness — O.D and nominal size — these nominal sizes and standard O.D.s continue in use as ‘‘standard.’’ The manufacture of pipe NPS 14 (DN 350) and larger proceeds on the basis of an O.D corresponding to the nominal size Variations in dimensions differ depending upon the method of manufacture employed in making the pipe to the various specifications available Permissible variations for dimensions are indicated in each specification MATERIALS The dimensional standards for pipe described here are for products covered in ASTM specifications PIPE THREADS Unless otherwise specified, the threads of threaded pipe shall conform to ANSI / ASME B1.20.1, Pipe Threads, General Purpose (Inch) Schedules and 10 wall thicknesses not permit threading in accordance with ANSI/ASME B1.20.1 WALL THICKNESS The nominal wall thicknesses are given in Table PERMISSIBLE VARIATIONS WEIGHTS The nominal weights of steel pipe are calculated
