A number in parentheses indicates the year of last reapproval. A superscript epsilon ( e ) 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 This specification is under the jurisdiction of Committee A01 on Steel, Stainless Steel and Related Alloys and is the direct responsibility of Subcommittee A01.09 on Carbon Steel Tubular Products. Current edition approved Dec. 10, 2002. March 1, 2004. Published December 2002. April 2004. Originally approved in 1926. Last previous edition in 2002 as A 106 – 02a. 1 This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version of the standard as published by ASTM is to be considered the official document.

Scope* 1.1 This specification 2 covers seamless carbon steel pipe for high-temperature service (Note 1) in NPS 1 / 8 to NPS 48 [DN 6 to DN 1200] inclusive, with nominal (average) wall thickness as given in ANSIME B 36.10M. It shall be permissible to furnish pipe having other dimensions provided such pipe complies with all other requirements of this specification. Pipe ordered under this specification shall be suitable for bending, flanging, and similar forming operations, and for welding. When the steel is to be welded, it is presupposed that a welding procedure suitable to the grade of steel and intended use or service will be utilized (Note 2). utilized. N OTE 1—It is suggested, consideration be given to possible graphitization. N OTE 2—The purpose for which the dimensionless designator NPS (nominal pipe is to be used should be stated size) [DN (diameter nominal)] has been substituted in the order. Grade A rather than Grade B or Grade C is the preferred grade this standard for close coiling or cold bending. This note is not intended to prohibit the cold bending of Grade B seamless pipe. such traditional terms as “nominal diameter,” “size,” and “nominal size.” 1.2 Supplementary requirements (S1 to S7) of an optional nature are provided for seamless pipe intended for use in applications where a superior grade of pipe is required. These supplementary requirements call for additional tests to be made and when desired shall be so stated in the order.shall be so stated in the order....
