1、Designation: B 710 04Standard Specification forNickel-Iron-Chromium-Silicon Alloy Welded Pipe1This standard is issued under the fixed designation B 710; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A n
2、umber in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) 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-resistingapplications and genera
3、l-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 SpecificationB 775 is based on Table A1 of ANSI B36.19 and gives thenominal dimension of these sizes. Table 3 of Specificat
4、ionB 775 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 the standard. The values given in parentheses are forin
5、formation only.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to become familiarwith all hazards including those identified in the appropriateMaterial Safety Data Sheet for this product/ma
6、terial as pro-vided by the manufacturer, to establish appropriate safety andhealth practices, and determine the applicability of regulatorylimitations prior to use.2.
