1.1 This specification covers nominal wall and mini- mum wall seamless frritic lloy-steel pipe intended for high-temperature service. Pipe ordered to this specification shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding. Selec- tion will depend upon design, service conditions, mechani- cal properties, and high-temperature characteristics.
1.2 Several grades of ferritic steels (see Note 1) are covered. Their compositions are given in Table 1. NOTE 1一Ferritie steels in this specification are defined as low- and intermediate- alloy steels containing u to and including 10% chromium.
1.3 Supplementary requirements (S1 to S7) of an optional nature are provided. These supplementary require- ments call for additional tests to be made, and when desired, shall be so stated in the order together with the number of such tests required.
1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the“M” designation of this specification is specified in the order. NOTE 2一The dimensionless designator NPS (nominal pipe size) has been substituted in this standard for such traditional terms as “nominal diameter,” “size,” and“nominal size.”
