2、se 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 spe
3、cification2covers nominal (average) wall seamless and welded carbon and alloy steel pipe intended for use at lowtemperatures. Several grades of ferritic steel are included as listed in Table 1. Some product sizes may not be available under thisspecification because heavier wall thicknesses have an a
4、dverse affect on low-temperature impact properties.1.2 Supplementary Requirement S1 of an optional nature is provided. This shall apply only when specified by the purchaser.1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI
5、 unitsare shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be usedindependently of the other. Combining values from the two systems may result in non-conformance with the standard. Theinch-pound units shall apply unless the “M” designatio
6、n of this specification is specified in the order.NOTE 1The dimensionless designator NPS (nominal pipe size) has been substituted in this standard for such traditional terms as “nominal diameter,”“size,” and “nominal size.”2.
