Fromthis survey, a table was designed to provide a selectionofwall thicknesses ofpipe to cover the power piping requirements of industry where strength to resist internal pressure governsselection andwas later expandedtoincludepipe diameters and thicknesses used in other industries.
The resulting Numbersdeparted so far from existing wall thicknesses in commonusethattheoriginal intent could not beaccomplished. The Schedule Numberswerethen adopted strictly as a convenient designationsystemfor use in ordering. Inall cases, the designer mustbasehisselection on the rules and allowable stresses set by the code which governs his particular construction. The table is dimensionally complete for all sizes andwallthicknesseswithinits scope, but some ofthe larger, heavier wall sections arebeyond the capability of seamlessmillproductionandmustbeobtainedfrom forged andboredbillets or othersources.
Subsequent slight revisionsto Table 1 andthe footnotes of thedimensional tables wereapprovedand the ASA changedthedesignation toAmerican Standard; the date ofASA approval wasApril 28, Further revisions weremade by theSectional Committee. It wasthehope in thatthedesignation of pipeused commercially by all industry as Standard weight, Extra-Strong, and Double Extra-Strong would gradually be replaced by Schedule Numberdesignation.
Consequently, in responseto a demandfromusers,acceptedpractice for dimensionsandweightsof commercialwroughtsteelandweldedwroughtironpipewereadded. Thesechangeswere SubcommitteeNo. In additiontonecessaryeditorialchanges, a simplifiedformat was selected for thetables of weightsand dimensions so astoinclude andidentifythe sizes andweights ofAPI Standards 5L and 5LX. These changestothe standard were approved and it was designated an American Standard on December 21, The standardwasrevised in A uniformmethodto calculate theplainendweight ofsteel pipe wasincluded,andminoradjustmentsweremade in the tabulatedweights of steelpipeinTable 2 toconformtothis newmethod.
Additional sizes andthicknesses of steelpipethathadcomeintocommon use were also addedto Table 2. These changesto the standardwereapprovedanditwasdesignated an AmericanNationalStandardonFebruary 3, Furtherrevisionsweremadetothestandard in Additional sizes andthicknesses ofsteelpipethathadbeenaddedtoAPIspecificationswereaddedto Table 2.
Table3, DimensionsandWeightsofWeldedWroughtIronPipe, was deleted in its entirety, since wroughtironpipeisnolongerproduced.

Theseconvertedandrounded SI metricdimensions wereaddedtoTable2. A formulatocalculatethe SI metricplainendmass, in kilograms per meter, using SI metric diameters and thicknesses was added to section 5. The SI metric plain end masswascalculatedand wasaddedto Table 2.
These changes in thestandard wereapprovedanditwasdesignatedanAmericanNationalStandardonJuly18, Furtherrevisionsweremade in Additional sizes and thicknesses of steel pipe that 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 and it was designated an American National Standard on June 5, The standard was revised in to include SI metric dimensions. The outside diameter and wall thicknesses were converted to millimeters by multiplying the inch dimensions by Outside diameters larger than 16 in.
Wall thicknesses were rounded to the nearest 0. These converted and rounded SI metric dimensions were added to Table 2. A formula to calculate the SI metric plain end mass, in kilograms per meter, using SI metric diameters and thicknesses was added to section 5. The SI metric plain end mass was calculated and was added to Table 2.
These changes in the standard were approved and it was designated an American National Standard on July 18, Further revisions were made in Additional sizes and thicknesses which had been added to API specifications were added to Table 2. That edition was approved as an American National Standard on August 19, The next edition included additional wall thicknesses and was approved by the American National Standards Institute on August 24, The 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 edition was approved as an American National Standard on September 23, The edition contained revisions to Table 2 to include the revised density for steel incorporated into Section 5 previously. Table 1 was deleted and other editorial changes to Sections 1, 2, 3, 5, 8, and 9 were made. The edition was approved as an American National Standard on December 1, The current edition contains revisions to Section 5 and Table 1.
It corrects the equation for nominal plain end weight.
It adds the missing DN schedule numbers in Table 1. This edition was approved as an American National Standard on June 23, Gruber, Chair J.

The word pipe is used, as distinguished from tube, to apply to tubular products of dimensions commonly used for pipeline and piping systems.
Pipe NPS 12 DN and smaller have outside diameters numerically larger than their corresponding sizes. In contrast, the outside diameters of tubes are numerically identical to the size number for all sizes. The manufacture of pipe NPS 1?
This OD was originally selected so that pipe with a standard OD and having a wall thickness that was typical of the period would have an inside diameter ID approximately equal to the nominal size. Permissible variations for dimensions are indicated in each specification. The dimensional standards for pipe described here are for products covered in ASTM specifications.
The nominal plain end weight, in pounds per foot, is calculated using the following formula: Wpe p As explained in the Foreword, the Schedule Numbers were subsequently added as a convenient designation for use in ordering pipe.
All larger sizes of Extra-Strong have 1?
