Designation:A376/A376M14Used in USDOE-NE standardsStandard Specification forSeamless Austenitic Steel Pipe for High-TemperatureService1This standard is issued under the fixed designation A376/A376M;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 seamless austenitic steel pipeintended for high-temperature service.Among the gradescovered are H grades and nitrogen grades that are specificallyintended for high-temperature service.NOTE1This specification was originally developed for use for pipingin the central stations of electric-power generating thermal plants.However,its use is not restricted to such applications and it may be usedin other applications for which the attributes of the materials,as defined bythis specification,are appropriate.1.2 Optional supplementary requirements(S1 through S10)are provided.These supplementary requirements specify addi-tional tests that will be made only when stated in the order,together with the number of such tests required.1.3 Grades TP321 and TP321H have lower strength require-ments for nominal wall thicknesses greater than38in.9.5mm.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 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.NOTE2The dimensionless designators NPS(nominal pipe size)andDN(Diametre Nominel)have been substituted in this standard for suchtraditional terms as“nominal diameter,”“size,”and“nominal size.”2.Referenced Documents2.1 ASTM Standards:3A262 Practices for Detecting Susceptibility to IntergranularAttack in Austenitic Stainless SteelsA999/A999M Specification for General Requirements forAlloy and Stainless Steel PipeE112 Test Methods for Determining Average Grain SizeE213 Practice for Ultrasonic Testing of Metal Pipe andTubingE381 Method of Macroetch Testing Steel Bars,Billets,Blooms,and ForgingsE426 Practice for Electromagnetic(Eddy-Current)Examina-tion of Seamless and Welded Tubular Products,Titanium,Austenitic Stainless Steel and Similar Alloys2.2 Other Standards:SNT-TC-1A Personnel Qualification and Certification inNondestructive Testing43.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(seamless austenitic steel pipe),3.1.3 Grade(Table 1),3.1.4 Size(nominal size,or outside diameter and schedulenumber or average wall thickness),3.1.5 Lengths(specific or random),(Permissible Variationsin Length Section of Specification A999/A999M),3.1.6 End finish(Ends Section of Specification A999/A999M),3.1.7 Optional requirements(Section 8)(see HydrostaticTest Requirements Section and the Permissible Variation inWeight for Seamless Pipe Section for weighing individuallengths,of Specification A999/A999M),(see 9.6,repairing bywelding;13.3,die stamping),3.1.8 Test report required(Certification Section of Specifi-cation A999/A999M),3.1.9 Specification designation,and3.1.10 Special requirements or any supplementary require-ments selected,or both.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 Oct.1,2014.Published November 2014.Originallyapproved in 1954.Last previous edition approved in 2013 as A376/A376M13.DOI:10.1520/A0376_A0376M-14.2For ASME Boiler and Pressure Vessel Code applications see related Specifi-cation SA-376 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 fromAmerican Society for Nondestructive Testing(ASNT),P.O.Box28518,1711 Arlingate Ln.,Columbus,OH 43228-0518.*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);4.General Requirements4.1 Material furnished to this specification shall conform tothe applicable requirements of the current edition of Specifi-cation A999/A999M unless otherwise provided herein.5.Materials and Manufacture5.1 ManufactureAt the manufacturers option
