Scope范围

1.1 This specification2 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 provided that such pipe 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.

1.1本规范2涵盖NPS 1/8至NPS 26[DN 6至DN 650]（含）的无缝焊接黑色热浸镀锌钢管，公称壁厚（注2）如表X2.2和表X2.3所示。允许提供具有其他尺寸的管道，前提是此类管道符合本规范的所有其他要求。提供了可选性质的补充要求，仅在买方指定时适用。

NOTE 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.”

注1：本规范中用无量纲指示符NPS（公称管道尺寸）[DN（公称直径）]代替了“公称直径”、“尺寸”和“公称尺寸”等传统术语

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.

注2：术语“标称壁厚”是为了便于命名而指定的，仅存在于名称中，用于将其与实际壁厚区分开来，实际壁厚可能在标称壁厚之上或之下变化。

1.2 This specification covers the following types and grades: 本规范涵盖以下类型和等级：

1.2.1 Type F—Furnace-butt-welded, continuous welded Grades A and B,  F型——炉对接焊接，A级和B级连续焊接，

1.2.2 Type E—Electric-resistance-welded, Grades A and B, and E型——电阻焊，A级和B级，以及

1.2.3 Type S—Seamless, Grades A and B.  S型——无缝，A级和B级。

NOTE 3: See Appendix X1 for definitions of types of pipe.  注3：管道类型的定义见附录X1。

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根据本规范订购的管道适用于机械和压力应用，也可用于蒸汽、水、气体和空气管线的普通用途。它适用于焊接，也适用于涉及卷取、弯曲和翻边的成型操作，但须符合以下资格：

1.3.1 Type F is not intended for flanging.F型不适用于翻边。

1.3.2 When pipe 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.

1.3.2当管道需要进行密卷或冷弯时，A级是首选等级；然而，这并不是为了禁止B级管道的冷弯。

1.3.3 Type E is furnished either nonexpanded or cold expanded at the option of the manufacturer.

1.3.3 E型可由制造商选择非膨胀或冷膨胀。

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.

1.4以国际单位制或英寸-磅单位表示的值应单独视为标准值。每个系统中所述的值可能不是完全等效的；因此，每个系统都应独立使用。将两个系统的值结合起来可能会导致不符合标准。

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.

1.5以下预防性警告仅适用于本规范第7、8、9、13、14和15节的测试方法部分：本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管要求的适用性。

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.

1.6本规范的文本包含注释或脚注，或两者兼而有之，提供解释性材料。此类注释和脚注（不包括表格和图表中的注释和脚注）不包含任何强制性要求。
