Standard Specification for Seamless and Welded Zirconium and Zirconium Alloy Pipe

ABSTRACT
This specification covers seamless and welded zirconium and zirconium alloy pipe. The pipe is furnished in three grades as follows; grade R60702- unalloyed zirconium, grade R60704- zirconium-tin alloy, and grade R60705- zirconium-niobium alloy. Seamless pipe shall be made from any seamless method that will yield a product meeting the requirements prescribed. Pipe containing welded seams or other joints made by welding shall comply with the given provisions. The pipe shall be furnished in the annealed or stress-relieved condition. The material shall conform to the requirements as to chemical composition prescribed. The material, as represented by the test specimens, shall conform to the tensile properties prescribed.
SCOPE
1.1 This specification2 covers three grades of seamless and welded zirconium pipe.  
1.2 Unless a single unit is used, for example corrosion mass gain in mg/dm2, the values stated in either inch-pound or SI units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore each system must be used independently of the other. SI values cannot be mixed with inch-pound values.  
1.3 The following precautionary caveat pertains only to the test methods portions of this specification: 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 and health practices and determine the applicability of regulatory limitations prior to use.

6. Materials and Manufacture
6.1 Seamless pipe shall be made from any seamless method that will yield a product meeting this specification.
6.2 Pipe containing welded seams or other joints made by welding shall comply with the following provisions:
6.2.1 Welded by welders, welding operators, and welding procedures qualified under the provisions of Section IX of the ASME
Boiler and Pressure Vessel Code.
6.2.2 Filler metal, when used, shall be the same grade as the base metal.
6.2.3 Welds in grade R60705 shall be stress relief annealed within 14 days after welding to prevent delayed hydride cracking.
The heat treatment shall be as follows:
6.2.3.1 The stress-relieving treatment shall consist of holding the pipe at a minimum temperature of 1100°F [600°C] for not less
than 30 min per inch [25mm] of the maximum thickness in a nonreducing atmosphere. The minimum time at this temperature is

7.1 The material shall conform to the requirements as to chemical composition prescribed in Table 1.
7.2 The manufacturer’smanufacturer’s ingot analysis shall be considered the chemical analysis for piping, except for hydrogen
and nitrogen, which shall be determined on the finished product.
7.3 When requested by the purchaser and stated in the purchase order, a product analysis for any elements listed in Table 1 shall
be made on the finished product.
7.3.1 The manufacturer’s analysis shall be considered as verified if the check analysis confirms the manufacturer’s reported

9.1.2 Thin-wall pipe usually develops significant ovality (out-of-roundness) during final annealing, straightening, or both.
Thin-wall pipe is defined as having a wall thickness of 3 % or less of the outside diameter. The diameter tolerances of Table 4 are
not sufficient to provide for additional ovality expected in thin-wall pipe and are applicable only to the mean of the extreme
(maximum and minimum) outside diameter readings in any one cross section. However, for thin-wall pipe the difference in extreme
outside diameter readings (ovality) in any one cross section shall not exceed 1.5 % of the specified outside diameter.
9.2 Thickness—The variation in thickness at any point shall not be more than 612.5 % of the nominal wall thickness specified.
9.3 Length:
9.3.1 Pipe shall be furnished in lengths as specified in the purchase order. No pipe shall be under the specified length and not
more than ⁄4 in. [6.4 mm] over that specified.
