2、ional dimensions is undiminished.Consequently,in response to a demand from users,accepted practice for dimensions and weights ofcommercial wrought steel and welded wrought iron pipe were added.These changes weredesignated an American Standard on February 23,1950.Subcommittee No.I was reorganized in
3、1957.In addition to necessary editorial changes,a simplified format was selected for the tables of weights and dimensions so as to includeand identify the sizes and weights of API Standards 5L and 5LX.These changes to thestandard were approved and it was designated an American Standard on December 2
4、1,1959.The standard was revised in 1969.A uniform method to calculate the plain end weightof steel pipe was included,and minor adjustments were made in the tabulated weights ofsteel pipe in Table 2 to conform to this new method.Additional sizes and thicknesses ofsteel pipe that had come into common
5、use were also added to Table 2.Inasmuch as APIStandard 5L no longer included wrought iron pipe,reference to this API Standard wasdeleted from Table 3.These changes to the standard were approved and it was designatedan American National Standard on February 3,1970.Further revisions were made to the s
6、tandard in 1975.Additional sizes and thicknessesof 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,sincewrought iron pipe is no longer produced.These changes in the standard were approve
7、dand it was designated an American National Standard on June 5,1975.The standard was revised in 1978 to include SI metric dimensions.The outside diameterand wall thicknesses were converted to millimeters by multiplying the inch dimensions by25.4.Outside diameters larger than 16 in.were rounded to th
8、e nearest millimeter.andoutside diameters 16 in.and smaller were rounded to the nearest 0.I mm.Wall thicknesseswere rounded to the nearest 0.01 mm.These converted and rounded SI metric dimensionswere added to Table 2.A formula to calculate the SI metric plain end mass,in kilogramsper meter,using SI
9、metric diameters and thicknesses was added to section 5.The SI metricplain end mass was calculated and was added to Table 2.These changes in the standardwere approved and it was designated an American National Standard on July 18,1979.Further revisions were made in 1984.The ANSI designations,which a
10、re no longer inuse,were deleted from Table 1,and the list of specifications was revised to agree withcurrent ASTM and API specifications.Additional sizes and thicknesses which had beenadded to API specifications were added to Table 2.That edition was approved as anAmerican National Standard on Augus
11、t 19,1985.The next edition included additional wall thicknesses and was approved by the AmericanNational Standards Institute on August 24,1995.The 1996 edition contained revisions to Table 2,adding pipe sizes,changing some plainend weights and masses,identifying metric pipe by the dimensionless desi
12、gnator DN,andeliminating the API Specification column.The 1996 edition was approved as an AmericanNational Standard on September 23,1996.The current edition contains revisions to Table 2 to include the revised density for steelincorporated into Section 5 previously.Table 1 was deleted and other editorial changes toSections 1,2,3,5,8,and 9 were made.This edition was approved as an American NationalStandard on December 1,2000.ivCOPYRIGHT American Society of Mechanical EngineersLicensed by Information Handling Services
