ASTM A409/A409M-08a

This document is not anASTM standard and is intended only to provide the user of anASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation:A 409/A 409M–08 Designation: A409/A409M – 08a
Standard Specification for
Welded Large Diameter Austenitic Steel Pipe for Corrosive
1
or High-Temperature Service
This standard is issued under the fixed designationA409/A409M; the number immediately following the designation indicates the year
of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.
A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope*

1.1 This specification covers straight seam or spiral seam electric-fusion-welded, light-wall, austenitic chromium-nickel alloy
steel pipe for corrosive or high-temperature service. The sizes covered are NPS 14 to 30 with extra light (Schedule 5S) and light
(Schedule 10S) wall thicknesses.Table X1.1 shows the wall thickness of Schedule 5S and 10S pipe. Pipe having other dimensions
may be furnished provided such pipe complies with all other requirements of this specification.
1.2 Several grades of alloy steel are covered as indicated in Table 1.
1.3 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.
1.4 Thevaluesstatedineitherinch-poundunitsorSIunitsaretoberegardedseparatelyasstandard.Withinthetext,theSIunits
are shown in brackets.The values stated in each system aremay not be exact equivalents; therefore, each system mustshall 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.
