1、Designation: B653/B653M 11 (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 c
2、ase 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 fromthree grades of zirconium and zircon
3、ium alloys. 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 a
4、re shown in brackets. 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 con
5、cerns, if any, 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.

Supplementary Requirement S3, StressRelief Heat Treatment.6. Materia
16、ls and Manufacture6.1 Forging, forming, or shaping operations may be per-formed by hammering, pressing, piercing, extruding, upsetting,rolling, bending, fusion welding, machining, or by a combina-tion of these operations. The forming procedure shall be soapplied that it will not produce injurious de
17、fects in the fittings.6.2 Fittings containing welded seams or other joints madeby welding shall comply with the following provisions:6.2.1 Welded by welders, welding operators, and weldingprocedures qualified under the provisions of Section IX of theASME Boiler and Pressure Vessel Code.6.2.2 Filler
18、metal, when used, shall be the same grade as thebase metal.6.2.3 All welds on grade R60705 shall be stress reliefannealed within 14 days after welding to prevent delayedhydride cracking, in accordance with Supplementary Require-ments Section S3, Stress Relief Heat Treatment.7. Chemical Composition7.
19、1 The material shall conform to the requirements as tochemical composition prescribed in Table 1.8. Tensile Requirements8.1 The material shall conform to the requirements as to thetensile properties prescribed in Table 1.9. Workmanship, Finish, and Appearance9.1 For fittings covered by ANSI B16.9 or
20、 MSS SP-43, orfor fittings to be used with pipe ordered to ANSI B36.19, thesizes, shapes, and dimensions of the fittings shall be asspecified in those standards.9.2 The fittings shall be free of injurious external andinternal imperfections of a nature that will interfere with thepurpose for which th
21、e fittings are intended. Minor defects maybe removed by grinding, providing the wall thickness is notdecreased to less than the minimum thickness, and furtherprovided that the ground-out area shall be faired out.10. Hydrostatic Tests10.1 All fittings shall be capable of withstanding withoutfailure,
22、leakage, or impairment of their serviceability, a testpressure prescribed in the applicable standards in Table 1 forthe pipe or tubing with which the fitting is planned to be used.10.2 Hydrostatic tests shall be performed when required bythe purchase order.11. Inspection11.1 The manufacturer shall i
23、nspect the material covered bythis specification prior to shipment. If so specified in thepurchase order, the purchaser or his representative may witnessthe testing and inspection of the material at the place ofmanufacture. In such cases the purchaser shall state in hispurchase order which tests he
24、desires to witness. The manu-facturer shall give ample notice to the purchaser as to the timeand place of the designated tests. If the purchasers represen-tative does not present himself at the time agreed upon for thetesting, the manufacturer shall consider the requirement for thepurchasers inspect
25、ion at the place of manufacture to bewaived.11.2 The manufacturer shall afford the inspector represent-ing the purchaser, without charge, all reasonable facilities tosatisfy him that the material is being furnished in accordancewith this specification.

The results of the referees testing shall beused in determining conformance of the material to thisspecificati
32、on.15. Product Marking15.1 Unless otherwise specified, the manufacturers name ortrademark, the schedule number, material, and size shall bestamped (see Note 2), stenciled, electroetched, or otherwisesuitably marked on each fitting. In addition, each fitting shallbe marked with the identification gra
33、de symbol and suffix forthe respective specification listed in Table 1. On wall thick-nesses thinner than Schedule 40S, no stamps or other indentedmarkings shall be used. When the size does not permitcomplete marking, identification marks may be omitted in thesequence shown in MSS SP-25.NOTE 2When s
34、teel stamps are used, they should be applied prior toheat treatment and care should be taken so that the marking is not deepenough to cause cracks or to reduce the wall thickness of the fitting belowthe minimum allowed.16.
