2、sion, 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 specification2covers three grades of seamless andwelded zirconium pipe.1.2 Unless a single unit
3、 is used, for example corrosion massgain in mg/dm2, the values stated in either inch-pound or SIunits are to be regarded separately as standard. The valuesstated in each system are not exact equivalents; therefore eachsystem must be used independently of the other. SI valuescannot be mixed with inch
4、-pound values.1.3 The following precautionary caveat pertains only to thetest methods portions of this specification: This standard doesnot purport to address all of the safety concerns, if any,associated with its use. It is the responsibility of the user of thisstandard to establish appropriate saf

Thin-wall pipe is defined as having a wall t
29、hickness of3 % or less of the outside diameter. The diameter tolerances ofTable 4 are not sufficient to provide for additional ovalityexpected in thin-wall pipe and are applicable only to the meanof the extreme (maximum and minimum) outside diameterreadings in any one cross section. However, for thi
30、n-wall pipethe difference in extreme outside diameter readings (ovality) inany one cross section shall not exceed 1.5 % of the specifiedoutside diameter.9.2 ThicknessThe variation in thickness at any point shallnot be more than 612.5 % of the nominal wall thicknessspecified.9.3 Length:9.3.1 Pipe sha
