1 Designation: A 53/A 53M 02 Standard Specification forPipe, steel , Black and Hot-Dipped, Zinc-Coated, Welded andSeamless1 This Standard is issued under the fixed designation A 53/A 53M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last superscript epsilon (e) indicates an editorial change since the last revision or Standard has been approved for use by agencies of the Department of Scope * This specification2covers seamless and welded blackand hot-dipped galvanized steel pipe in NPS1 8to NPS 26 [DN6 to DN 650] (Note 1), inclusive, with nominal wall thickness(Note 2) as given in Table and Table It shall bepermissible to furnish pipe having other dimensions (Note 2)provided such pipe complies with all other requirements of The dimensionless designators NPS (nominal pipe size) [DN(diameter nominal)] have been substituted in this specification for suchtraditional terms as nominal diameter, size, and nominal size.

2 NOTE2 The 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 This specification covers the following types F Furnace-butt welded, continuous weldedGrade A, E Electric-resistance welded, Grades A and B, S seamless , Grades A and See Appendix X1 for definitions of types of Pipe ordered under this specification is intended formechanical and pressure 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- Type F is not intended for When Types S and E are required for close coiling orcold bending, Grade A is the preferred grade. This provision isnot intended to prohibit the cold bending of Grade B Type E is furnished either nonexpanded or coldexpanded at the option of the The values stated in either SI units or inch-pound unitsare to be regarded separately as Standard .

Materials and The steel for both seamless and welded pipe shall bemade by one or more of the following processes: open-hearth,electric-furnace, or When steels of different grades are sequentially strandcast, identification of the resultant transition material is re-quired. The producer shall remove the transition material byany established procedure that positively separates the The weld seam of electric-resistance welded pipe inGrade B shall be heat treated after welding to a minimum of1000 F [540 C] so that no untempered martensite remains, orotherwise processed in such a manner that no untemperedmartensite When pipe is cold expanded, the amount of expansionshall not exceed 11 2% of the outside diameter pipe Book of ASTM Standards, Vol Book of ASTM Standards, Vol Book of ASTM Standards, Vol from American National Standards Institute (ANSI), 25 W. 43rd St.,4th Floor, New York, NY from American Society of Mechanical Engineers (ASME), ASMEI nternational Headquarters, Three Park Ave.
