Designation:A928/A928M14Standard Specification forFerritic/Austenitic(Duplex)Stainless Steel Pipe ElectricFusion Welded with Addition of Filler Metal1This standard is issued under the fixed designation A928/A928M;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 specification covers electric-fusion-welded steelpipe suitable for corrosive service.NOTE1The dimensionless designator NPS(nominal pipe size)hasbeen substituted in this specification for traditional terms such as nominaldiameter,size,and nominal size.1.2 This specification covers grades of ferritic/austeniticsteel as indicated in Table 1.The selection of the proper alloyand requirements for heat treatment shall be at the discretion ofthe purchaser,dependent on the service conditions to beencountered.1.3 Five classes of pipe are covered as follows:1.3.1 Class 1Pipe shall be double welded by processesusing filler metal in all passes and shall be radiographedcompletely.1.3.2 Class 2Pipe shall be double welded by processesusing filler metal in all passes.No radiograph is required.1.3.3 Class 3Pipe shall be single welded by processesusing filler metal in all passes and shall be radiographedcompletely.1.3.4 Class 4Same as Class 3,except that the weld passexposed to the inside pipe surface is permitted to be madewithout the addition of filler metal(see 6.2.2.1 and 6.2.2.2).1.3.5 Class 5Pipe shall be double welded by processesusing filler metal in all passes and shall be spot radiographed.1.4 Supplementary requirements covering provisions rang-ing from additional testing to formalized procedures formanufacturing practice are provided.Supplementary Require-ments S1 through S4 are included as options to be specified inthe purchase order when desired.1.5 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 Mdesignation of the specification is specified in the order.2.Referenced Documents2.1 ASTM Standards:2A240/A240M Specification for Chromium and Chromium-Nickel Stainless Steel Plate,Sheet,and Strip for PressureVessels and for General ApplicationsA480/A480M Specification for General Requirements forFlat-Rolled Stainless and Heat-Resisting Steel Plate,Sheet,and StripA941 Terminology Relating to Steel,Stainless Steel,RelatedAlloys,and FerroalloysA999/A999M Specification for General Requirements forAlloy and Stainless Steel PipeE426 Practice for Electromagnetic(Eddy-Current)Examina-tion of Seamless and Welded Tubular Products,Titanium,Austenitic Stainless Steel and Similar Alloys2.2 ASME Boiler and Pressure Vessel Code:3Section IIISection VIIISection IX2.3 AWS Specifications:4A 5.4 Corrosion-Resisting Chromium and Chromium-Nickel Steel Covered Welding ElectrodesA 5.9 Corrosion-Resisting Chromium and Chromium-Nickel Steel Welding Rods and Bare ElectrodesA 5.11 Nickel and Nickel-Alloy Covered Welding Elec-trodesA 5.14 Nickel and Nickel-Alloy Bare Welding Rods andElectrodes1This 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 October 2014.Originallyapproved in 1994.Last previous edition approved in 2013 as A928/A928M13.DOI:10.1520/A0928_A0928M-14.2For 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.3Available from American Society of Mechanical Engineers(ASME),ASMEInternational Headquarters,Two Park Ave.,New York,NY 10016-5990,http:/www.asme.org.4Available from American Welding Society(AWS),550 NW LeJeune Rd.,Miami,FL 33126,http:/www.aws.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);A 5.22 Flux Cored Corrosion-Resisting Chromium andChromium-Nickel Steel ElectrodesA 5.30 Consumable Weld Inserts for Gas Tungsten ArcWelding3.Terminology3.1 Definitions:3.1.1 The definitions in Specification A999/A999M andTerminology A941 are applicable to this specification.4.Ordering Information4.1 It shall be the responsibility of the purchaser to specifyall requirements that are necessary for product under thisspecification.Such require
