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

Thin-wall pipe is defined as having a wall t

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.
