1 Designation: A 106/A 106M 06aUsed in USDOE-NE standardsStandard Specification forSeamless Carbon Steel Pipe for High-Temperature Service1 This Standard is issued under the fixed designation A 106/A 106M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last superscript epsilon (e) indicates an editorial change since the last revision or Standard has been approved for use by agencies of the Department of Scope* This specification2covers Seamless Carbon Steel pipe forhigh-temperature service (Note 1)inNPS1 8to NPS 48 [DN 6to DN 1200] (Note 2) inclusive, with nominal (average) wallthickness as given inASME B It shall be permissibleto furnish pipe having other dimensions provided such pipecomplies with all other requirements of this specification. Pipeordered under this specification shall be suitable for bending,flanging, and similar forming operations, and for the Steel is to be welded, it is presupposed that a weldingprocedure suitable to the grade of Steel and intended use orservice will be It is suggested, consideration be given to possible The dimensionless designator NPS (nominal pipe size) [DN(diameter nominal)] has been substituted in this Standard for suchtraditional terms as nominal diameter, size, and nominal size.

2 Supplementary requirements of an optional nature areprovided for Seamless pipe intended for use in applicationswhere a superior grade of pipe is required. These supplemen-tary requirements call for additional tests to be made and whendesired shall be so stated in the The values stated in either SI units or inch-pound unitsare to be regarded separately as Standard . The values stated ineach system may not be exact equivalents. Therefore, eachsystem is to be used independently of the The following precautionary caveat pertains only to thetest method portion, Sections11,12, and13of this specifica-tion:This Standard does not purport to address all of the safetyconcerns, if any, associated with its use.

5 Ifsecondary melting, using electroslag remelting or vacuum-arcremelting is subsequently employed, the heat shall be definedas all of the ingots remelted from a single primary Steel cast in ingots or strand cast is permissible. Whensteels of different grades are sequentially strand cast, identifi-cation of the resultant transition material is required. Theproducer shall remove the transition material by any estab-lished procedure that positively separates the For pipe NPS 11 2[DN 40] and under, it shall bepermissible to furnish hot finished or cold Unless otherwise specified, pipe NPS 2 [DN 50] andover shall be furnished hot finished. When agreed uponbetween the manufacturer and the purchaser, it is permissibleto furnish cold-drawn Heat Hot-finished pipe need not be heat treated. Cold-drawnpipe shall be heat treated after the final cold draw pass at atemperature of 1200 F (650 C) or General Material furnished to this specification shall conform tothe applicable requirements of the current edition of Specifi-cationA 530/A 530 Munless otherwise provided Chemical The Steel shall conform to the requirements as tochemical composition prescribed inTable Heat An analysis of each heat of Steel shall be made by thesteel manufacturer to determine the percentages of the ele-ments specified in Section7.

The chemical composition thus deter-mined, or that determined from a product analysis made by themanufacturer, if the latter has not manufactured the Steel , shallbe reported to the purchaser or the purchaser s representative,and shall conform to the requirements specified in Product At the request of the purchaser, analyses of two pipesfrom each lot ( ) shall be made by the manufacturerfrom the finished pipe.

In such cases,the marking of each length of pipe so furnished shall includethe letters NDE. It is the intent of this nondestructive electrictest to reject pipe with imperfections that produce test signalsequal to or greater than that produced by the applicablecalibration Where the nondestructive electric test is performed, thelengths shall be marked with the letters NDE.
