Designation:A369/A369M11(Reapproved 2016)Standard Specification forCarbon and Ferritic Alloy Steel Forged and Bored Pipe forHigh-Temperature Service1This standard is issued under the fixed designation A369/A369M;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 reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification2covers heavy-wall carbon and alloysteel pipe(Note 1)made from turned and bored forgings and isintended for high-temperature service.Pipe ordered under thisspecification shall be suitable for bending and other formingoperations and for fusion welding.Selection will depend ondesign,service conditions,mechanical properties and high-temperature characteristics.NOTE1The use of the word“pipe”throughout the several sections ofthis specification is used in the broad sense and intended to mean pipeheaders,or leads.NOTE2The dimensionless designator NPS(nominal pipe size)hasbeen substituted in this standard for such traditional terms as“nominaldiameter,”“size,”and“nominal size.”1.2 Several grades of ferritic steels are covered.Theircompositions are given in Table 1.1.3 Supplementary requirements(S1 to S6)of an optionalnature are provided.These supplementary requirements call foradditional tests to be made,and when desired shall be so statedin the order,together with the number of such tests required.1.4 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.Within the text,theSI units are shown in brackets.The values stated in eachsystem may not be exact equivalents;therefore,each systemshall be used independently of the other.Combining valuesfrom the two systems may result in non-conformance with thestandard.The inch-pound units shall apply unless the“M”designation of this specification is specified in the order.2.Referenced Documents2.1 ASTM Standards:3A999/A999M Specification for General Requirements forAlloy and Stainless Steel PipeE290 Test Methods for Bend Testing of Material for Ductil-ityE381 Method of Macroetch Testing Steel Bars,Billets,Blooms,and Forgings2.2 ASME Boiler and Pressure Vessel Code:4Section IX2.3 ANSI Standard:5B 46.1 Surface Texture2.4 AWS Specifications:6A5.5/A5.5M Specification for Low-Alloy Steel Electrodesfor Shielded Metal Arc WeldingA5.23/A5.23M Specification for Low-Alloy Steel Elec-trodes and Fluxes for Submerged Arc WeldingA5.28/A5.28M Specification for Low-Alloy Steel Elec-trodes for Gas Shielded Arc WeldingA5.29/A5.29M Low-Alloy Steel Electrodes for Flux CoredArc Welding3.Ordering Information3.1 Orders for material to this specification should includethe following,as required,to describe the desired materialadequately:3.1.1 Quantity(feet,centimetres,or number of lengths),3.1.2 Name of material(forged and bored pipe),3.1.3 Grade(Table 1),3.1.4 Size(inside diameter and minimum wall thickness),3.1.5 Length(Permissible Variations in Length Section ofSpecification A999/A999M),3.1.6 Verification of tensile and hardness properties atmid-thickness for Grade FP91(9.2)3.1.7 End finish(13),3.1.8 Optional requirements(Sections 8,SupplementaryRequirements S1 to S6;13.2),1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.10 on Stainless and Alloy Steel Tubular Products.Current edition approved Sept.1,2016.Published September 2016.Originallyapproved in 1953.Last previous edition approved in 2011 as A369/A369M 11.DOI:10.1520/A0369_A0369M-11R16.2For ASME Boiler and Pressure Vessel Code applications see related Specifi-cation SA-369 in Section II of that Code.3For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.4Available from American Society of Mechanical Engineers(ASME),ASMEInternational Headquarters,Two Park Ave.,New York,NY 10016-5990,http:/www.asme.org.5Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.6Available from American Welding Society(AWS),550 NW LeJeune Rd.,Miami,FL 33126,http:/www.aws.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.1.9 Test report required(Certification Section of Specifi-cation A999/A999M),3.1.10 Specification designation,and3.1.11 Special requirements or exceptions to this specifica-tion.4.General Requirements4.1 Material furnished under this specification shall con-form to the applicable requirements of the current edition ofSpecification A999/A999M,unless otherwise provided herein.5.Materials and Manufacture5.1 Discard:5.1.1 A sufficient discard shall be made from each ing
