1、Designation: B366/B366M 17Standard Specification forFactory-Made Wrought Nickel and Nickel Alloy Fittings1This standard is issued under the fixed designation B366/B366M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of l
2、ast revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers wrought welding fittings forpressure piping, factory-made from nickel and nickel alloys.Thre
3、aded fittings as covered in ASME B16.11 are also coveredby this specification. The term welding applies to butt-weldingor socket-welding parts such as 45 and 90 elbows, 180 bends,caps, tees, reducers, lap-joint stub ends, and other types, ascovered by ASME B16.9, ASME B16.11, MSS SP-43, MSSSP-95, an
4、d MSS SP-97.1.1.1 Several grades of nickel and nickel alloys are includedin this specification. Grades are designated with a prefix, WPorCR, based on the applicable ASME or MSS dimensional andrating standards.1.1.2 Class WP fittings are those manufactured to therequirements of ASME B16.9, B16.11.1.1
5、.3 For each of the WP nickel and nickel alloy grades,several classes of fittings are covered to indicate whetherseamless or welded construction was utilized. Class designa-tions are also utilized to indicate the nondestructive test methodand extent of nondestructive examination (NDE). Table 1 isgene
6、ral summary of the fitting classes applicable to all WPgrades of nickel and nickel alloys covered by this specification.There are no classes for the CR grades. Specific requirementsare covered elsewhere.1.2 This specification does not apply to cast welding fit-tings.1.3 Optional supplementary requir
7、ements are provided forfittings where a greater degree of examination is desired. Thesesupplementary requirements call for additional tests. Whendesired, one or more of these may be specified in the order.1.4 The values stated in either SI units or inch-pound unitsare to be regarded separately as st
8、andard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.5 This standard does not purport to address all of thesafety concerns, if any, a
