1、Designation: A 409/A 409M 08Standard Specification forWelded Large Diameter Austenitic Steel Pipe for Corrosiveor High-Temperature Service1This standard is issued under the fixed designationA 409/A 409M; the number immediately following the designation indicates the yearof original adoption or, in t
2、he case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification2covers straight seam or spiral seamelectric-fusion-welded, light
3、-wall, austenitic chromium-nickelalloy steel pipe for corrosive or high-temperature service. Thesizes covered are NPS 14 to 30 with extra light (Schedule 5S)and light (Schedule 10S) wall thicknesses. Table X1.1 showsthe wall thickness of Schedule 5S and 10S pipe. Pipe havingother dimensions may be f
4、urnished provided such pipe com-plies with all other requirements of this specification.1.2 Several grades of alloy steel are covered as indicated inTable 1.1.3 Optional supplementary requirements are provided.These call for additional tests to be made, and when desiredshall be stated in the order,
5、together with the number of suchtests required.1.4 The values stated in either inch-pound units or SI unitsare to be regarded separately as standard. Within the text, theSI units are shown in brackets. The values stated in eachsystem are not exact equivalents; therefore, each system mustbe used inde
6、pendently of the other. Combining values from thetwo systems may result in nonconformance with the specifi-cation. The inch-pound units shall apply unless the “M”designation of this specification is specified in the order.NOTE 1The dimensionless designator NPS (nominal pipe size) hasbeen substituted
7、 in this standard for such traditional terms as nominaldiameter, size, and nominal size.2.
