2、ision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1NOTEEditorially corrected Table 3 in April 2015.1.Scope*1.1 This specification covers two classes of flanged andcold-bending quality cold-wo
3、rked straight-seam single ordouble welded austenitic steel pipe intended for high-temperature and general corrosive services.NOTE1When the impact test criterion for a low-temperature servicewould be 15 ftlbf 20 J energy absorption or 15 mils 0.38 mm lateralexpansion,some of the austenitic stainless
4、steel grades covered by thisspecification are accepted by certain pressure vessel or piping codeswithout the necessity of making the actual test.For example,Grades 304,304L,and 347 are accepted by the ASME Pressure Vessel Code,SectionVIII Division 1,and by the Chemical Plant and Refinery Piping Code
5、,ANSI B31.3 for service at temperatures as low as 425 F 250 Cwithout qualification by impact tests.Other AISI stainless steel grades areusually accepted for service temperatures as low as 325 F 200 Cwithout impact testing.Impact testing may,under certain circumstances,be required.For example,materia
6、ls with chromium or nickel contentoutside the AISI ranges,and for material with carbon content exceeding0.10%,are required to be impact tested under the rules of ASME SectionVIII Division 1 when service temperatures are lower than 50 F 45C.1.2 Grades TP304H,TP304N,TP316H,TP316N,TP321H,TP347H,and TP3
7、48H are modifications of Grades TP304,TP316,TP321,TP347,and TP348,and are intended forhigh-temperature service.1.3 Two classes of pipe are covered as follows:1.3.1 Class SWPipe,single-welded with no addition offiller metal and1.3.2 Class DWPipe,double-welded with no addition offiller metal.1.4 Optio
8、nal supplementary requirements are provided forpipe where a greater degree of testing is desired.Thesesupplementary requirements call for additional tests to be madeand,when desired,one or more of these may be specified in theorder.1.5 Table 1 lists the dimensions of cold-worked single-ordouble-weld
9、ed stainless steel pipe.Pipe having other dimen-sions may be furnished provided such pipe complies with allother requirements of this specification.1.6 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.
10、The values stated in eachsystem are not exact equivalents;therefore,each system mustbe used independently 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 specifie
