An American National Standard

Standard Specification for

Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless1
This standard is issued under the fixed designation A 53/A 53M; thenumber immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense.

1. Scope 1.1 Thisspecification2 covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 1⁄8 to NPS 26 [DN 6 to DN 650] (Note 1), inclusive, with nominal wall thickness (Note 2) as given in Table X2.2 and Table X2.3. It shall be permissible to furnish pipe having other dimensions (Note 2) provided such pipe complies with all other requirements of this specification.
NOTE 1—The dimensionlessdesignators NPS (nominal pipe size) [DN (diameter nominal)] have been substituted in this specification for such traditional terms as “nominal diameter,” “size,” and “nominal size.” NOTE 2—The term nominal wall thickness has been assigned for the purpose of convenient designation, existing in name only, and is used to distinguish it from the actual wall thickness, which may vary over or under thenominal wall thickness.

1.2 This specification covers the following types and grades: 1.2.1 Type F—Furnace-butt welded, continuous welded Grade A, 1.2.2 Type E—Electric-resistance welded, Grades A and B, and 1.2.3 Type S—Seamless, Grades A and B.
NOTE 3—See Appendix X1 for definitions of types of pipe.

1.4 The values stated in either SI units or inch-pound units are to be regarded separately asstandard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.5 The following precautionary caveat pertains only to the test method portion, Sections 9, 10, 11, 15, 16, and 17 of this specification: This standard does not purport toaddress all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1.6 The text of this specification contains notes or footnotes, or both, that provide explanatory material. Such notes and footnotes, excluding those in tablesand figures, do not contain any mandatory requirements. 2.
