Designation:A672/A672M14Standard Specification forElectric-Fusion-Welded Steel Pipe for High-Pressure Serviceat Moderate Temperatures1This standard is issued under the fixed designation A672/A672M;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 steel pipe:electric-fusion-welded with filler metal added,fabricated from pressure-vesselquality plate of any of several analyses and strength levels andsuitable for high-pressure service at moderate temperatures.Heat treatment may or may not be required to attain the desiredproperties or to comply with applicable code requirements.Supplementary requirements are provided for use when addi-tional testing or examination is desired.1.2 The specification nominally covers pipe 16 in.400mm in outside diameter or larger with wall thicknesses up to3 in.75 mm,inclusive.Pipe having other dimensions may befurnished provided it complies with all other requirements ofthis specification.1.3 Several grades and classes of pipe are provided.1.3.1 Grade designates the type of plate used.1.3.2 Class designates the type of heat treatment performedduring manufacture of the pipe,whether the weld is radio-graphically examined,and whether the pipe has been pressuretested as listed in 1.3.3.1.3.3 Class designations are as follows(Note 1):ClassHeat Treatment on PipeRadiography,see SectionPressure Test,see Section10nonenonenone11none9none12none98.313nonenone8.320stress relieved,see 5.3.1nonenone21stress relieved,see 5.3.19none22stress relieved,see 5.3.198.323stress relieved,see 5.3.1none8.330normalized,see 5.3.2nonenone31normalized,see 5.3.29none32normalized,see 5.3.298.333normalized,see 5.3.2none8.340normalized and tempered,see 5.3.3nonenone41normalized and tempered,see 5.3.39none42normalized and tempered,see 5.3.398.343normalized and tempered,see 5.3.3none8.350quenched and tempered,see 5.3.4nonenone51quenched and tempered,see 5.3.49none52quenched and tempered,see 5.3.498.353quenched and tempered,see 5.3.4none8.3NOTE1Selection of materials should be made with attention totemperature of service.For such guidance,Specification A20/A20M maybe consulted.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:3A20/A20M Specification for General Requirements for SteelPlates for Pressure VesselsA370 Test Methods and Definitions for Mechanical Testingof Steel ProductsA435/A435M Specification for Straight-Beam UltrasonicExamination of Steel PlatesA530/A530M Specification for General Requirements forSpecialized Carbon and Alloy Steel PipeA577/A577M Specification for Ultrasonic Angle-Beam Ex-amination of Steel PlatesA578/A578M Specification for Straight-Beam UltrasonicExamination of Rolled Steel Plates for Special Applica-tionsE109 Method for Dry Powder Magnetic Particle Inspection;Replaced by E 709(Withdrawn 1981)4E138 Method for Wet Magnetic Particle Inspection;Re-placed by E 709(Withdrawn 1981)41This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.09 on Carbon Steel Tubular Products.Current edition approved May 1,2014.Published May 2014.Originallyapproved in 1972.Last previous edition approved in 2009 as A672/A672M 091.DOI:10.1520/A0672_A0672M-14.2For ASME Boiler and Pressure Vessel Code applications see related Specifi-cation SA-672 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.*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);E110 Test Method for Indentation Hardness of MetallicMaterials by Portable Hardness TestersE165 Practice for Liquid Penetrant Examination for GeneralIndustryE709 Guide for Magnetic Particle Testing2.1.1 Plate Steel Specifications(Table 1)A204/A204M Specification for Pressure Vessel Plates,AlloySteel,MolybdenumA285/A285M Specification for Pressure Vessel Plates,Car-bon Steel,Low-and Intermedi
