1、Designation: B366 10aStandard Specification forFactory-Made Wrought Nickel and Nickel Alloy Fittings1This standard is issued under the fixed designation B366; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revisio
2、n. A number in parentheses indicates the year of last reapproval. Asuperscript 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.Threaded fittin
3、gs 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, and MSS SP-97
4、.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, B16.11.1.1.3 For each
5、 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 isgeneral summary
6、 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 requirements are
7、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 inch-pound units are to be regardedas standard. The values given in parentheses a
8、re mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.5 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 hazar
9、ds 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.
