2、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 specification2covers nominal
3、 (average) wall seam-less and welded carbon and alloy steel pipe intended for use atlow temperatures. Several grades of ferritic steel are includedas listed in Table 1. Some product sizes may not be availableunder this specification because heavier wall thicknesses havean adverse affect on low-tempe
4、rature impact properties.1.2 Supplementary Requirement S1 of an optional nature isprovided. This shall apply only when specified by the pur-chaser.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. Within the text, theSI units are shown in brackets
5、. The values stated in eachsystem may not be exact equivalents; therefore, each systemshall be used independently of the other. Combining valuesfrom the two systems may result in non-conformance with thestandard. The inch-pound units shall apply unless the “M”designation of this specification is spe
