1、Designation: A312/A312M 11Used in USDOE-NE standardsStandard Specification forSeamless, Welded, and Heavily Cold Worked AusteniticStainless Steel Pipes1This standard is issued under the fixed designation A312/A312M; the number immediately following the designation indicates the yearof original adopt
2、ion 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.This standard has been approved for use by agencies of the Department of Defense.1. S
3、cope*1.1 This specification2covers seamless, straight-seamwelded, and heavily cold worked welded austenitic stainlesssteel pipe intended for high-temperature and general corrosiveservice.NOTE 1When the impact test criterion for a low-temperature servicewould be 15 ftlbf 20 J energy absorption or 15
4、mils 0.38 mm lateralexpansion, some of the austenitic stainless steel grades covered by thisspecification are accepted by certain pressure vessel or piping codeswithout the necessity of making the actual test. For example, GradesTP304, TP304L, and TP347 are accepted by the ASME Pressure VesselCode,
5、Section VIII Division 1, and by the Chemical Plant and RefineryPiping Code, ANSI B31.3, for service at temperatures as low as 425 F250 C without qualification by impact tests. Other AISI stainless steelgrades are usually accepted for service temperatures as low as 325 F200 C without impact testing.
6、Impact testing may, under certaincircumstances, be required. For example, materials with chromium ornickel content outside the AISI ranges, and for material with carboncontent exceeding 0.10 %, are required to be impact tested under the rulesof ASME Section VIII Division 1 when service temperatures
7、are lowerthan 50 F 45 C.1.2 Grades TP304H, TP309H, TP309HCb, TP310H,TP310HCb, TP316H, TP321H, TP347H, and TP348H aremodifications of Grades TP304, TP309Cb, TP309S, TP310Cb,TP310S, TP316, TP321, TP347, and TP348, and are intendedfor service at temperatures where creep and stress ruptureproperties are
8、 important.1.3 Optional supplementary requirements are provided forpipe where a greater degree of testing is desired. Thesesupplementary requirements call for additional tests to be madeand, when desired, it is permitted to specify in the order one ormore of these supplementary requirements.1.4 Tabl
9、e X1.1 lists the standardized dimensions of weldedand seamless stainless steel pipe as shown in ANSI B36.19.These dimensions are also applicable to heavily cold workedpipe. Pipe having other dimensions is permitted to be orderedand furnished provided such pipe complies with all otherrequirements of
10、this specification.1.5 Grades TP321 and TP321H have lower strength require-ments for pipe manufactured by the seamless process innominal wall thicknesses greater than38 in. 9.5 mm.1.6 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. Within the text,
11、theSI units are shown in brackets. The values stated in eachsystem may not be exact equivalents; therefore, each systemshall be used independently of the other. Combining valuesfrom the two systems may result in non-conformance with thestandard. The inch-pound units shall apply unless the “M”designa
12、tion of this specification is specified in the order.NOTE 2The dimensionless designator NPS (nominal pipe size) hasbeen substituted in this standard for such traditional terms as “nominaldiameter,” “size,” and “nominal size.”2.
