1、Designation: B 710 04 (Reapproved 2009)Standard 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
2、last 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-resistingapplic
3、ations 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 SpecificationB 775 is based on Table A1 of ANSI B36.19 and gives thenominal dimension of these sizes. Tabl
4、e 3 of SpecificationB 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 standard. The values given in parenthe
5、ses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.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
6、hazards including those identified in the appropriateMaterial Safety Data Sheet (MSDS) for this product/materialas provided by the manufacturer, to establish appropriatesafety and health practices, and determine the applicability ofregulatory limitations prior to use.2.

Materials and Manufacture6.1 The pipe shall be made from flat-rolled alloy conform-ing to Specification B 536, by an automatic welding process
16、with no addition of filler metal. Subsequent to welding andprior to final heat treatment, the material shall be cold workedeither in both weld and base metal or in weld metal only.6.2 Heat TreatmentPipe of UNS N08330 alloy shall beannealed at 1900F (1040C), minimum. Pipe of UNS N08332alloy shall be
17、annealed at 2100F (1150C), minimum.7. Chemical Composition7.1 The material shall conform to the composition limitsspecified in Table 1. One test is required for each lot as definedin Specification B 775.7.2 If a product analysis is performed, it shall meet thechemistry limits prescribed in Table 1,
