2、 yearof 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.This standard has been approved for use by agencies of the U.S.

3、 Department of Defense.1. Scope*1.1 This specification2 covers nominal-wall-thickness welded tubes and heavily cold worked welded tubes made from theaustenitic steels listed in Table 1, with various grades intended for such use as boiler, superheater, heat exchanger, or condensertubes.1.2 Grades TP3

4、04H, TP309H, TP309HCb, TP310H, TP310HCb, TP316H, TP321H, TP347H, and TP348H are modificationsof Grades TP304, TP309S, TP309Cb, TP310S, TP310Cb, TP316, TP321, TP347, and TP348, and are intended for high-temperature service such as for superheaters and reheaters.1.3 The tubing sizes and thicknesses us

5、ually furnished to this specification are 18 in. 3.2 mm in inside diameter to 12 in. 304.8mm in outside diameter and 0.015 to 0.320 in. 0.4 to 8.1 mm, inclusive, in wall thickness. Tubing having other dimensions maybe furnished, provided such tubes comply with all other requirements of this specific

6、ation.1.4 Mechanical property requirements do not apply to tubing smaller than 18 in. 3.2 mm in inside diameter or 0.015 in. 0.4mm in thickness.1.5 Optional supplementary requirements are provided and, when one or more of these are desired, each shall be so stated inthe order.1.6 The values stated i

7、n either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI unitsare shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be usedindependently of the other. Combining values from the two systems ma

8、y result in non-conformance with the standard. Theinch-pound units shall apply unless the “M” designation of this specification is specified in the order.1.7 The following safety hazards caveat pertains only to the test method described in the Supplementary Requirements of thisspecification. This st

9、andard does not purport to address all of the safety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appropriate safety safety, health, and healthenvironmental practices anddetermine the applicability of regulatory limitations prior to use
