    1. Scope

    1.1 This specification2 covers centrifugally cast alloy steel pipe intended for use in high-temperature, high-pressure service.

    1.2 Several grades of ferritic steels are covered. Their compositions are given in Table 1.

    (A) Where ellipses appear in this table, there is no requirement, and the element need not be analyzed or reported.
    (B) All values are maximums unless a range is provided.

    1.3 Supplementary Requirements S1 through S12 are provided. The supplementary requirements provide for additional tests of an optional nature and, when desired, shall be so stated in the order (Section 4).

    1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. 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 nonconformance with the standard.

    1.4.1 Within the text, the SI units are shown in brackets.

    1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.6 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.
