1、Designation:A53/A53M12Standard Specification forPipe,Steel,Black and Hot-Dipped,Zinc-Coated,Welded andSeamless1This standard is issued under the fixed designation A53/A53M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of l
2、ast revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This specification2covers seamless an
3、d welded blackand hot-dipped galvanized steel pipe in NPS18to NPS 26 DN6 to DN 650(Note 1),inclusive,with nominal wall thickness(Note 2)as given in Table X2.2 and Table X2.3.It shall bepermissible to furnish pipe having other dimensions providedthat such pipe complies with all other requirements of
4、thisspecification.Supplementary requirements of an optional na-ture are provided and shall apply only when specified by thepurchaser.NOTE1The dimensionless designators NPS(nominal pipe size)DN(diameter nominal)have been substituted in this specification for suchtraditional terms as“nominal diameter,
5、”“size,”and“nominal size.”NOTE2The term nominal wall thickness has been assigned for thepurpose of convenient designation,existing in name only,and is used todistinguish it from the actual wall thickness,which may vary over orunder the nominal wall thickness.1.2 This specification covers the followi
6、ng types andgrades:1.2.1 Type FFurnace-butt-welded,continuous weldedGrade A,1.2.2 Type EElectric-resistance-welded,Grades A and B,and1.2.3 Type SSeamless,Grades A and B.NOTE3See Appendix X1 for definitions of types of pipe.1.3 Pipe ordered under this specification is intended formechanical and press
7、ure applications and is also acceptable forordinary uses in steam,water,gas,and air lines.It is suitablefor welding,and suitable for forming operations involvingcoiling,bending,and flanging,subject to the following quali-fications:1.3.1 Type F is not intended for flanging.1.3.2 If Type S or Type E i
8、s required for close coiling orcold bending,Grade A is the preferred grade;however,this isnot intended to prohibit the cold bending of Grade B pipe.1.3.3 Type E is furnished either nonexpanded or coldexpanded at the option of the manufacturer.1.4 The values stated in either SI units or inch-pound un
9、itsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.5 The following precautionary caveat pertains
