1.1 This specification covers two classes of fit-up and alignment quality straight-seam single- or double-welded austenitic steel pipe intended for high-temperature and general corrosive service. 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 welded stainless steel pipe as shown in ANSI B36.19. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specification. 1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 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 accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
