1、Designation: A 814/A 814M 08Standard Specification forCold-Worked Welded Austenitic Stainless Steel Pipe1This standard is issued under the fixed designationA 814/A 814M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of l
2、ast 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 specification covers two classes of flanged andcold-bending quality cold-worked straight-seam single ordouble we
3、lded austenitic steel pipe intended for high-temperature and general corrosive services.NOTE 1When 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 steel grades covered by thisspecifi
4、cation 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,ANSI B31.3 for service at tem
5、peratures 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, materials with chromium or nicke
6、l 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 TP348H are modificat
7、ions 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 Optional supplem
8、entary 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-welded stai
9、nless 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. The
10、 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 specif
