Standard Specification for Seamless and Welded Steel Pipe for Low-Temperature Service
|Publication Date:||1 March 2005|
|ICS Code (Iron and steel pipes):||23.040.10|
Supplementary Requirement S1 of an optional nature is provided. This shall apply only when specified by the purchaser.
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-333 in Section II of that Code.
