(Specification)Standard Specification for Seamless and Welded Zirconium and Zirconium Alloy Welding Fittings
Standard Specification for Seamless and Welded Zirconium and Zirconium Alloy Welding Fittings
ABSTRACT
This specification covers fittings, factory made from three grades of zirconium and zirconium alloys. The term welding fittings applies to butt-welding parts such as 45 and 90° elbows, 180° returns, caps, tees, reducers, lap-joint stub ends, and other types. The fittings are furnished in three grades as follows: Grade R60702 or PZ 2 which is unalloyed zirconium, Grade R60704 or PZ4 which is zirconium-tin, and Grade R60705 or PZ5 which is zirconium-niobium. Forging, forming, or shaping operations may be performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining, or by a combination of these operations. The forming procedure shall be so applied that it will not produce injurious defects in the fittings. Filler metal, when used, shall be the same grade as the base metal. The material shall conform to the requirements as to chemical composition and tensile properties specified.
SCOPE
1.1 This specification covers fittings, factory made from three grades of zirconium and zirconium alloys. The term welding fittings applies to butt-welding parts such as 45 and 90° elbows, 180° returns, caps, tees, reducers, lap-joint stub ends, and other types.
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 SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently 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 the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
