1、Designation: B 653/B 653M 06Standard Specification forSeamless and Welded Zirconium and Zirconium AlloyWelding Fittings1This standard is issued under the fixed designation B 653/B 653M; the number immediately following the designation indicates the yearof original adoption or, in the case of revisio
2、n, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers fittings, factory made fromthree grades of zirconium and zirconium alloys. T
3、he termwelding fittings applies to butt-welding parts such as 45 and90 elbows, 180 returns, caps, tees, reducers, lap-joint stubends, and other types.1.2 The values stated in either inch-pound units or SI unitsare to be regarded separately as the standard. Within the text,the SI units are shown in b
4、rackets. The values stated in eachsystem are not exact equivalents; therefore, each system mustbe used independently of the other. Combining values from thetwo systems may result in nonconformance with the specifi-cation.1.3 This standard does not purport to address all of thesafety concerns, if any
5、, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
