1.1?This specificationNote 1:?The dimensionless designators 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 the nominal 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, and 1.2.3?Type SSeamless, Grades A and B. Note 3:?See Appendix X1
for definitions of types of pipe.
1.3?Pipe ordered under this specification is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas, and air lines. It is suitable for welding, and suitable for forming operations involving coiling, bending, and flanging, subject to the following qualifications: 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 not intended to prohibit the cold bending of Grade B pipe. 1.3.3?Type E is furnished either nonexpanded or cold expanded at the option 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 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 7, 8, 9, 13, 14, and 15 of this specification: This standard does not purport to address 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, health, and environmental practices and determine the applicability of regulatory requirements 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 tables and figures, do not contain any mandatory requirements. 1.7?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
