Designation:A660/A660M11(Reapproved 2016)Standard Specification forCentrifugally Cast Carbon Steel Pipe for High-TemperatureService1This standard is issued under the fixed designation A660/A660M;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.Scope*1.1 This specification2covers carbon steel pipe made by thecentrifugal casting process intended for use in high-temperature,high-pressure service.Pipe ordered under thisspecification shall be suitable for fusion welding,bending,andother forming operations.1.2 Several grades of carbon steels are covered.Theircompositions are given in Table 1.1.3 Supplementary requirements(S1 to S9)of an optionalnature are provided.The 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 inch-pound units or SI unitsare to be regarded separately as standard.Within the text,theSI units are shown in brackets.The values stated in eachsystem are not exact equivalents;therefore,each system mustbe used independently of each other.Combining values fromthe two systems may result in nonconformance with thespecification.2.Referenced Documents2.1 ASTM Standards:3A530/A530M Specification for General Requirements forSpecialized Carbon and Alloy Steel PipeE94 Guide for Radiographic ExaminationE114 Practice for Ultrasonic Pulse-Echo Straight-BeamContact TestingE125 Reference Photographs for Magnetic Particle Indica-tions on Ferrous CastingsE142 Method for Controlling Quality of Radiographic Test-ing(Withdrawn 2000)4E186 Reference Radiographs for Heavy-Walled(2 to 412in.(50.8 to 114 mm)Steel CastingsE381 Method of Macroetch Testing Steel Bars,Billets,Blooms,and ForgingsE446 Reference Radiographs for Steel Castings Up to 2 in.(50.8 mm)in Thickness2.2 ANSI Standards:B36.10 American Standard for Welded and SeamlessWrought Steel Pipe5B46.1 Surface Texture52.3 MSS Standards:SP-54 Quality Standard for Steel Castings for Valves,Flanges,and Fittings and Other Piping Components-Radiographic Examination Method63.Ordering Information3.1 Orders for material under this specification shouldinclude the following,as required,to describe the desiredmaterial adequately:3.1.1 Quantity(feet,metres,or number of lengths),3.1.2 Name of material(centrifugally cast pipe),3.1.3 Grade(Table 1),3.1.4 Size(outside or inside diameter and minimum wallthickness),3.1.5 Length(specific or random),(Permissible Variationsin Length Section of Specification A530/A530M),3.1.6 End finish(Ends Section of Specification A530/A530M),3.1.7 Optional Requirements(Sections 7.2,8.2,8.3,11.1,Section 12 and S1 to S9(Supplementary Requirements),3.1.8 Test report required(Certification Section of Specifi-cation A530/A530M),3.1.9 Specification designation,and3.1.10 Special requirements.1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.18 on Castings.Current edition approved Sept.1,2016.Published September 2016.Originallyapproved in 1972.Last previous edition approved in 2011 as A660/A660M 11.DOI:10.1520/A0660_A0660M-11R16.2For ASME Boiler and Vessel Code applications see related SpecificationSA-660 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.4The last approved version of this historical standard is referenced onwww.astm.org.5Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.6Available from Manufacturers Standardization Society of the Valve and FittingsIndustry(MSS),127 Park St.,NE,Vienna,VA 22180-4602,http:/www.mss-.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.General Requirements4.1 Material furnished under this specification shall con-form to the applicable requirements of the current edition ofSpecification A530/A530M unless otherwise provided herein.5.Materials and Manufacture5.1 Machining:5.1.1 All centrifugally cast pipe shall have both the innerand outer surfaces machined.5.1.2 After heat treatment,the pipe shall be machined to afinish with a roughness value no greater than 250 in.6.35m arithmetical average deviation(AA),terms as defined inANSI B46.1 unless otherwise specified.5.2 Heat Treatment:5.2.1 All pipe shall receive a heat treatment proper for itsdesign and chemical composition.5.2.2 Castings shall be heat treated after they have beena
