Designation: A814/A814M −15 (Reapproved 2019)
Standard Specification for
Cold-Worked Welded Austenitic Stainless Steel Pipe
1
This standard is issued under the fixed designation A814/A814M; 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 two classes of flanged and
cold-bending quality cold-worked straight-seam single or
double welded austenitic steel pipe intended for high-
temperature and general corrosive services.
NOTE 1—When the impact test criterion for a low-temperature service
would be 15 ft·lbf [20 J] energy absorption or 15 mils [0.38 mm] lateral
expansion, some of the austenitic stainless steel grades covered by this
specification are accepted by certain pressure vessel or piping codes
without the necessity of making the actual test. For example, Grades 304,
304L, and 347 are accepted by the ASME Pressure Vessel Code, Section
VIII Division 1, and by the Chemical Plant and Refinery Piping Code,
ANSI B31.3 for service at temperatures as low as −425 °F [−250 °C]
without qualification by impact tests. Other AISI stainless steel grades are
usually accepted for service temperatures as low as −325 °F [−200 °C]
without impact testing. Impact testing may, under certain circumstances,
be required. For example, materials with chromium or nickel content
outside the AISI ranges, and for material with carbon content exceeding
0.10 %, are required to be impact tested under the rules of ASME Section
VIII Division 1 when service temperatures are lower than −50 °F [−45
°C].
1.2 Grades TP304H, TP304N, TP316H, TP316N, TP321H,
TP347H, and TP348H are modifications of Grades TP304,
TP316, TP321, TP347, and TP348, and are intended for
high-temperature service.
1.3 Two classes of pipe are covered as follows:
1.3.1 Class SW—Pipe, single-welded with no addition of
filler metal and
1.3.2 Class DW—Pipe, double-welded with no addition of
filler metal.
1.4 Optional supplementary requirements are provided for
pipe where a greater degree of testing is desired. These
supplementary requirements call for additional tests to be made
and, when desired, one or more of these may be specified in the
order.
1.5 Table 1 lists the dimensions of cold-worked single- or
double-welded stainless steel pipe. Pipe having other dimen-
sions may be furnished provided such pipe complies with all
other requirements of this specification.
1.6 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 specifi-
cation. The inch-pound units shall apply unless the “M”
designation of this specification is specified in the order.
1.7 This international standard was developed in accor-
dance with internationally recognized principles on standard-
ization established in the Decision on Principles for the
Development of International Standards, Guides and Recom-
mendations issued by the World Trade Organization Technical
Barriers to Trade (TBT) Committee.
