3 AMERICA ATIOAL STADARD FOR WELDED AD SEAMLESS WROUGHT STEEL PIPE (ASI )1 FOREWORD In March, 1927, the American Standards Association authorized the organization of a Sectional Commit tee on Standardization of Dimensions aizd 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, Pa., on May,19. 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 (ASME Trans., vol. VIII, page 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. Increa:singly severe service demands at the time of the committee's organization, had been met by using the nearest available pipe or tubing for heavier secfions, such as casing, mechanical tubing, etc., with result ing uneconomical multiplicity of wall thicknesses. Subsequently; the committee, with the cooperation of the industry, made a survey of existing practice as the logical statting 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 Committe.e was to establish a system of Schedule umbers for pipe size/wall combinations which would have an approximately uniform relationship equal to 00 times the PIS expres sion contained in the modified Barlow formula for pipe wall thickness as defined in the Appendix to this standard. The resulting umbers departed so far from existing wall tllicknesses in common use that the original intent could not be accolilplished. The Scheoule umbers were th'e:n 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 goverils 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 approved by letter ballot of the Sectional Committee in October 19; by The American Society of Mechanic,al Engineers in ovember 19, and by the AmericaIi Society for Testing and Materials in February Formal approval was given with the designation American Stan dard' "tentative," by the American Standards Association, ovember Subsequent slight revisions to Table 1 and the footl\otes of the dimensional tables were approved in order by the Sectional Committee, the Sponsors, and the Am~rican Standards Association, The latter changed the designation to American Standard; date of approval April, Further revisions have been made by the Sectional Committee and approved by the Sponsors and the American Standards Association. The list of specifications in Table I has been revised where necessary and slight revisions in wall thicknesses of some of the large sizes of the heavy schedules have been made where PIS values were out of line. It was the hope in 1939 that the designations of pipe used commercially by all industry as standard weight, extra strong, and double extra strong would gradually be replaced by Schedule umber designation. However, owing to customs of over fifty 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 wrougllt steel and welded wrought iron pipe, were added. These changes in the Standard were approved by the Sectional Committee, the Sponsors, and the Amer ican Standards Association, and it was designated an American Standard on February

4 Subcommittee o.1 was reorganized in 1957 to revise and bring the Standard up to date. In addition to the necessary editorial.changes, a simplified format was selected for the tables of weights and dimensions so as to include and to identify the sizes and weights of API Standards and 5 LX. The decimal wall thicknesses and plain end weights were established by a uniform procedure recognized by the tubular industry, and for some sizes the decimal wall thicknesses and plain end weights shown may vary slightly from those shown in the tables of previous issues of this Standard. These changes were approved by the Sectional Committee, the Sponsors, and the American Standards Association, and it was designated an American Standard on December 21,1959. This Standard was revised in 199 to bring it up to date. 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 2 to conform to this new method. Additional sizes and thicknesses of steel pipe which have come into common use were also added to Table 2. Inasmuch as API Standard no longer included wrought iron pipe, reference to this API Standard was deleted from Table 3. These changes in the Standard were approved by the Standards Committee, the Sponsors, and the American ational Standards Institute, and it was designated an American ational Standard on February 3, Further revisions were made.(0 this Standard in Additional sizes and thickness of steel pipe which had been added to API Specifications were added to Table 2. 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 by the Standards Committee, the Secretariat, and the American ational Standards Institute, and it was designated an American ational Standard on June 5, This Standard was revised in 197 to include SI metric dimensions. The outside diameter and wall thicknesses were converted to mm by multiplying the inch dimensions by Outside diameters larger than " were rounded to' the nearest mm, and outside diameter " 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 adde.d to Table 2.' A formula to calculate the SI metric plain end mass', kg/m, using SI metric diameters and thicknesses was adde.d to SectionS. TheSI metric plain end mass was calculated for each size and thickness, and was added to Table 2. These changes in the Standard were approved by the Standards Committee. the Secretariat, and the American ational Standards Institute, and it was designed an American ational Standard on July, Reprinted by permission of the 'American Society of Mechanical Engineers, 5 East 47th St., ew York,.Y

5 ASI AMERICA ATIOAL STADARD WELDED AD SEAMLESS WROUGHT STEEL PIPE 1. SCOPE This Standard covers the standardization of dimensions of welded and seamless wrought steel pipe, for high or low temperatures and pressures. The word pipe is used as distinguished from tube to apply to tubular products of dimimsions commoil1y used for pipelin.e and piping systems. Pipe dimensions of sizes inch and smaller have ou'tside diameters numerically larger than corresponding sizes. In contrast, the outside diameters of tubes are numerically identical to the size number for all sizes. :1. SIZE The size of all pipe is iden tified by the nominal pipe size. The manufacture of pipe in the nominal sizes of 1/ inch to inches inclusive is based on a standardized outside diameter (OD). This OD was originally selected so that pipe with a standard OD and having a wall thickness which was typical of the period would have an inside diameter (ID) approximately equal to the nominal size. Although there is no such relation between the existing standard thickness-od and nominal size-these nominal sizes and standard ODs continue in use as "standard." The manufacture of pipe in nominal sizes of 14 inch OD and larger. proceeds on the basis of an OD corresponding to the nominal size. 3. MATERIALS The dimensional standards for pipe described here arc for products covered in the ASTM and API specifi cations listed in Table WALL THICKESS The nominal wall thicknesses are given in Table 2. Table 2 also indicates wall thicknesses listed in API Standards, X and S. 5. WEIGHTS The nominal weights of steel pipe are calculated values and are tabulated in Table 2. The nominal plain end weights, lbs./ft., are cal culated using the following formula: where Wpe =. (D - t) t Wpe = nominal plain end weight rounded to the nearest 0.01 lb./ft. D = outside diameter to the nearest in.. (The symbol D is to be used for 00 only in h1athematical equations or fomulas.) = specified wall thickness rounded to the nearesfd.ool in: The nominal plain _end mass, kg/m, is calculated using the following formula: where Wpe = (D - /) / Wpe = nominal plain end mass rounded to the nearest kg/m D = outside diameter (0 the nearest 0.1 mm for outside diameters which are in. and smaller and 1.0 mm for outside diameter larger than in. (The symbol D is to be used for OD only in mathematical equations or formulas). specified wall thickness rounded to the ncarest 0.0 I mm.. PERMISSIBLE VARIATIOS Variations in dimensions differ depending upon the method of manufacture cmployed in maldng the pipe to the various specifications listed in Table 1. Permis' sible variations for dimensions are indicated in each specification. 70

6 AMERICA ATIOAL STADARD WELDED AD SEAMLESS WROUGHT STEEL PIPE ASI PIPE THREADS Unless otherwise specified, the threads of threaded pipe shall conform to ASI B2.l Pipe Threads (Ex cept Drysea/).. WALL THICKESS DESIGATIOS The wall thickness designations "Standard", "Extra Strong", and Double Extra Strong" have been commercially used designations for many years. As ex plained in the Foreword, the Schedule umbers were subsequently added as a convenient designation for use in ordering pipe. Standard and Schedule are iden tical for nominal pipe sizes up to inch inclusive. All larger sizes of Standard have 3/ inch wall thickness. Extra Strong and Schedule are identical for nom inal pipe sizes up to inch inclusive. All larger sizes of Extra Strong have 1/2 inch wall thickness. Pipe'of sizes and wall thickness other than those of Standard, Extra Strong, Double Extra Strong, and Schedule umber were adopted from API Standards, X and S. It was not considered practical to establish Schedule umbers nor new designations for them. 9. WALL THICKESS SELECTIO When the selection of wall thickness depends primarily upon capacity to resist internal pressure under given conditions, the designer shall compute the exact value of wall thickness suitable for conditions for which the pipe is required as prescribed in detail in the ASME Boiler and Pressure Vessel Code, ASI B3l Code for Pressure Piping, or other similar codes, whichever governs the construction. A thickness shall be selected from Table 2 to suit the value computed to fulflll the conditions for which the pipe is desired. / 71
