1、Designation:B653/B653M11(Reapproved 2016)Standard Specification forSeamless and Welded Zirconium and Zirconium AlloyWelding Fittings1This standard is issued under the fixed designation B653/B653M;the number immediately following the designation indicates the yearof original adoption or,in the case o
2、f revision,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.Scope1.1 This specification covers fittings,factory made fromthree grades of zirconium and zirconium alloys.
3、The 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 bracket
4、s.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,associated
5、 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.Referenced Documents2.1 ASTM Standards:2B493 Specification for Zirconium and Zirconium AlloyForgingsB523/
