Optional supplementary requirements (S1 through S10) are provided. These supplementary requirements specify additional tests that will be made only when stated in the order, together with the number of such tests required.
Grades TP321 and TP321H have lower strength requirements for nominal wall thicknesses greater than ⅜ in. [9.5 mm].
The values stated in either inch-pound units or SI units are to be regarded separately as 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. The inch-pound units shall apply unless the "M" designation of this specification is specified in the order.
NOTE 1 - The dimensionless designator NPS (nominal pipe size) has been substituted in this standard for such traditional terms as "nominal diameter," "size," and "nominal size."
Footnote * - A Summary of Changes section appears at the end of this standard.
Footnote 2 - For ASME Boiler and Pressure Vessel Code applications see related Specification SA-376 in Section II of that Code.
