1、Designation: B464 10B464/B464M 15Standard Specification forWelded UNS N08020 Alloy Pipe1This standard is issued under the fixed designation B464;B464/B464M; the number immediately following the designation indicates theyear of original adoption or, in the case of revision, the year of last revision.

2、 A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification2 covers welded UNS N08020 alloy pipe for general corrosion-resisting and low- or high-temperatureservice.1.2 The

3、 pipe covered is nominal pipe sizes up to and including NPS 6, 6 168 mm with the nominal wall thicknesses givenas Schedules 5S, 10S, and 40S and nominal pipe sizes up to and including NPS 2, 2 60 mm also including Schedule 80S. Table 2of Specification B775 is based on Table A1 of ANSI B36.19 and giv

4、es the nominal dimensions of these sizes. Table 3 ofSpecification B775 lists the dimensional requirements of these sizes. Pipe having other dimensions may be furnished provided suchpipe complies with all other requirements of this specification.1.3 The values stated in either SI units or inch-pound

5、units are to be regarded separately as standard. The values given inparentheses are mathematical conversions to SI units that are provided for information only and are not considered stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. C

6、ombining values from thetwo systems may result in non-conformance with the standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to become familiar with all hazards including those iden
