    1、Designation:A53/A53M10 Designation: A53/A53M 12Standard 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

    2、 case of revision, the year of last 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 Department of Defense.1. Scope*1.1 This

    3、specification2covers seamless and welded black and hot-dipped galvanized steel pipe in NPS18 to NPS 26 DN 6 toDN 650 (Note 1), inclusive, with nominal wall thickness (Note 2) as given in Table X2.2 and Table X2.3. It shall be permissibleto furnish pipe having other dimensions provided that such pipe

    4、 complies with all other requirements of this specification.Supplementary requirements of an optional nature are provided and shall apply only when specified by the purchaser.NOTE 1The dimensionless designators NPS (nominal pipe size) DN (diameter nominal) have been substituted in this specification

    5、 for suchtraditional terms as “nominal diameter,” “size,” and “nominal size.”NOTE 2The term nominal wall thickness has been assigned for the purpose of convenient designation, existing in name only, and is used to distinguishit from the actual wall thickness, which may vary over or under the nominal

    6、 wall thickness.1.2 This specification covers the following types and grades:1.2.1 Type FFurnace-butt-welded, continuous welded Grade A,1.2.2 Type EElectric-resistance-welded, Grades A and B, and1.2.3 Type SSeamless, Grades A and B.NOTE 3See Appendix X1 for definitions of types of pipe.1.3 Pipe orde

    8、ons:1.3.1 Type F is not intended for flanging.1.3.2 If Type S or Type E is required for close coiling or cold bending, Grade A is the preferred grade; however, this is notintended to prohibit the cold bending of Grade B pipe.1.3.3 Type E is furnished either nonexpanded or cold expanded at the option

    9、 of the manufacturer.1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result

    10、in non-conformance with the standard.1.5 The following precautionary caveat pertains only to the test method portion, Sections 7, 8, 9, 13, 14, and 15 of thisspecification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is theresponsibility

    11、of the user of this standard to establish appropriate safety and health practices and determine the applicability ofregulatory requirements prior to use.1.6 The text of this specification contains notes or footnotes, or both, that provide explanatory material. Such notes andfootnotes, excluding thos
