1、Designation: B710 04 (Reapproved 2015)Standard Specification forNickel-Iron-Chromium-Silicon Alloy Welded Pipe1This standard is issued under the fixed designation B710; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of la
2、st revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification2covers alloys UNS N08330 and UNSN08332 in the form of welded pipe intended for heat-resistingapplicat
3、ions and general-corrosive service.1.2 The pipe covered is nominal pipe sizes up to andincluding size 12, with the nominal wall thicknesses given asSchedules 5S, 10S, 40S, and 80S. Table 2 of SpecificationB775 is based on Table A1 of ANSI B36.19 and gives thenominal dimension of these sizes. Table 3
4、 of SpecificationB775 lists the dimensional requirements of these sizes. Pipehaving other dimensions may be furnished provided such pipecomplies with all other requirements of this specification.1.3 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses
