1、Designation:B653/B653M06 Designation: B653/B653M 11Standard 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, i
2、n the case of 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 from three grades of zirconium an
3、d zirconium alloys. The term weldingfittings applies to butt-welding parts such as 45 and 90 elbows, 180 returns, caps, tees, reducers, lap-joint stub ends, and othertypes.1.2 The values stated in either inch-pound units or SI units are to be regarded separately as the standard. Within the text, the
4、SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be usedindependently of the other. Combining values from the two systems may result in nonconformance with the specification.1.3 This standard does not purport to address all of th
5、e safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use.2.
