A number in parentheses indicates the year of last reapproval.A superscript epsilon (e) 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 nom

3、inal (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-t

4、emperature 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 inch-pound units or SI unitsare to be regarded separately as standard. Within the text, theSI units are shown in brac

5、kets. The values stated in eachsystem are not exact equivalents; therefore, each system mustbe used independently of the other. Combining values from thetwo systems may result in nonconformance with the specifi-cation. The inch-pound units shall apply unless the “M”designation of this specification

Workmanship, Finish and Appearance10.1 The pipe manuf

44、acturer shall explore a sufficient num-ber of visual surface imperfections to provide reasonableassurance that they have been properly evaluated with respectto depth. Exploration of all surface imperfections is notrequired but may be necessary to ensure compliance with 10.2.10.2 Surface imperfection

45、s that penetrate more than 12 %of the nominal wall thickness or encroach on the minimumwall thickness shall be considered defects. Pipe with suchdefects shall be given one of the following dispositions:10.2.1 The defect may be removed by grinding providedthat the remaining wall thickness is within s

46、pecified limits.10.2.2 Repaired in accordance with the repair weldingprovisions of 10.5.10.2.3 The section of pipe containing the defect may be cutoff within the limits of requirements on length.10.2.4 The defective pipe may be rejected.10.3 To provide a workmanlike finish and basis for evalu-ating

47、conformance with 10.2, the pipe manufacturer shallremove by grinding the following:10.3.1 Mechanical marks, abrasions and pits, any of whichimperfections are deeper than116 in. 1.6 mm, and10.3.2 Visual imperfections commonly referred to as scabs,seams, laps, tears, or slivers found by exploration in

48、 accor-dance with 10.1 to be deeper than 5 % of the nominal wallthickness.10.4 At the purchasers discretion, pipe shall be subject torejection if surface imperfections acceptable under 10.2 are notscattered, but appear over a large area in excess of what isconsidered a workmanlike finish. Dispositio

49、n of such pipe shallbe a matter of agreement between the manufacturer and thepurchaser.10.5 When imperfections or defects are removed by grind-ing, a smooth curved surface shall be maintained, and the wallthickness shall not be decreased below that permitted by thisspecification.The outside diameter at the point of grinding maybe reduced by the amount so removed.10.5.1 Wall thickness measurements shall be made with amechanical caliper or w
