Designation:A426/A426M13Standard Specification forCentrifugally Cast Ferritic Alloy Steel Pipe for High-Temperature Service1This standard is issued under the fixed designation A426/A426M;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 centrifugally cast alloy steelpipe intended for use in high-temperature,high-pressure ser-vice.1.2 Several grades of ferritic steels are covered.Theircompositions are given in Table 1.1.3Supplementary Requirements S1 through S12 areprovided.The supplementary requirements provide for addi-tional tests of an optional nature and when desired shall be sostated in the order(Section 4).1.4 The values stated in either inch-pound units or SI unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith 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 thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:3A370 Test Methods and Definitions for Mechanical Testingof Steel ProductsA609/A609M Practice for Castings,Carbon,Low-Alloy,and Martensitic Stainless Steel,Ultrasonic ExaminationThereofA941 Terminology Relating to Steel,Stainless Steel,RelatedAlloys,and FerroalloysA999/A999M Specification for General Requirements forAlloy and Stainless Steel PipeE94 Guide for Radiographic ExaminationE165 Practice for Liquid Penetrant Examination for GeneralIndustryE186 Reference Radiographs for Heavy-Walled(2 to 412-in.(50.8 to 114-mm)Steel CastingsE208 Test Method for Conducting Drop-Weight Test toDetermine Nil-Ductility Transition Temperature of Fer-ritic SteelsE280 Reference Radiographs for Heavy-Walled(412to 12-in.(114 to 305-mm)Steel CastingsE446 Reference Radiographs for Steel Castings Up to 2 in.(50.8 mm)in ThicknessE709 Guide for Magnetic Particle Testing2.2 ANSI Standard:4B46.1 Surface Texture2.3 ASME Boiler and Pressure Vessel Code:5Section IX Welding and Brazing Qualifications3.Ordering Information3.1 Orders for material under this specification shall 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(centrifugally cast pipe),3.1.3 Specification number,3.1.4 Grade(Table 1),3.1.5 Size(outside or inside diameter and minimum wallthickness),3.1.6 Length(specific or random)(Section on PermissibleVariations in Length of Specification A999/A999M),3.1.7 End finish(Section on Ends of Specification A999/A999M),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 Nov.1,2013.Published November 2013.Originallyapproved in 1958.Last previous edition approved in 2011 as A426/A426M-11a.DOI:10.1520/A0426_A0426M-13.2For ASME Boiler and Pressure Vessel Code applications see related Specifi-cation SA-426 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 National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.5Available from American Society of Mechanical Engineers(ASME),ASMEInternational Headquarters,Two Park Ave.,New York,NY 10016-5990,http:/www.asme.org.*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 States1Copyright by ASTM Intl(all rights reserved);3.1.8 Optional Requirements S1 through S12 and Section14.1,3.1.9 Test report required(Section on Certified Test Reportof Specification A999/A999M),3.1.10 Service temperature if over 1000F 540C(Note 1),and3.1.11 Special requirements or additions to specification.4.General Requirements for Delivery4.1 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 Heat-TreatmentThe pipe shall be furnished in theaustenitized and tempered condition(Note 1)according to therequirements of Table 2.5.1.1 Heat treatment shall be performed after the pipe hasbeen
