Standard Specification for Welded Large Diameter Austenitic Steel Pipe for Corrosive or High-Temperature Service
|Publication Date:||1 November 2019|
|ICS Code (Iron and steel pipes):||23.040.10|
This specification2 covers straight seam or spiral seam electric-fusion-weld
Several grades of alloy steel are covered as indicated in Table 1.
Optional supplementary requirements are provided. These call for additional tests to be made, and when desired shall be stated in the order, together with the number of such tests required.
The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 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.
This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
