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)]

2 ] have been substituted in this specification for suchtraditional terms as nominal diameter, size, and nominal size. 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.

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 . 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 The following precautionary caveat pertains only to thetest method portion, Sections 9, 10, 11, 15, 16, and 17 of thisspecification:This Standard does not purport to address all ofthe safety concerns, if any, associated with its use.
