1、Designation: B366/B366M 16B366/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,
2、the year of last 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 for pressure piping, factory-made from nickel and nick
3、el alloys. Threadedfittings as covered in ASME B16.11 are also covered by this specification. The term welding applies to butt-welding orsocket-welding parts such as 45 and 90 elbows, 180 bends, caps, tees, reducers, lap-joint stub ends, and other types, as coveredby ASME B16.9, ASME B16.11, MSS SP-
4、43, MSS SP-95, and MSS SP-97.1.1.1 Several grades of nickel and nickel alloys are included in this specification. Grades are designated with a prefix, WP orCR, based on the applicable ASME or MSS dimensional and rating standards.1.1.2 Class WP fittings are those manufactured to the requirements of A
5、SME B16.9, B16.11.1.1.3 For each of the WP nickel and nickel alloy grades, several classes of fittings are covered to indicate whether seamless orwelded construction was utilized. Class designations are also utilized to indicate the nondestructive test method and extent ofnondestructive examination
6、(NDE). Table 1 is general summary of the fitting classes applicable to all WP grades of nickel andnickel alloys covered by this specification. There are no classes for the CR grades. Specific requirements are covered elsewhere.1.2 This specification does not apply to cast welding fittings.1.3 Option
7、al supplementary requirements are provided for fittings where a greater degree of examination is desired. Thesesupplementary requirements call for additional tests. When desired, one or more of these may be specified in the order.1.4 The values stated in either SI units or inch-pound units are to be
8、 regarded separately as standard. The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.1.5 This standard does not purport to address all of t
9、he safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to become familiar with all hazards including those identified in the appropriate Safety Data Sheet(SDS) for this product/material as provided by the manufacturer, to establish appropriate safet
10、y and health practices, anddetermine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardizationestablished in the Decision on Principles for the Development of International Standa
