1、Designation:A214/A214M96(Reapproved 2012)Standard Specification forElectric-Resistance-Welded Carbon Steel Heat-Exchangerand Condenser Tubes1This standard is issued under the fixed designation A214/A214M;the number immediately following the designation indicates the yearof original adoption or,in th
2、e 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.This standard has been approved for use by agencies of the Department of Defense.1.Scope1.1 This speci
3、fication2covers minimum-wall-thickness,electric-resistance-welded,carbon steel tubes to be used forheat exchangers,condensers,and similar heat-transfer appara-tus.1.2 The tubing sizes usually furnished to this specificationare to 3 in.76.2 mm in outside diameter,inclusive.Tubinghaving other dimensio
4、ns may be furnished,provided suchtubes comply with all other requirements of this specification.1.3 Mechanical property requirements do not apply totubing smaller than18in.3.2 mm in inside diameter or 0.015in.0.4 mm in thickness.1.4 The purchaser shall specify in the order the outsidediameter and mi
5、nimum wall thickness.The inside diametershall not be specified.1.5 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 mustb
6、e used independently of the other.Combining values from thetwo systems may result in nonconformance with the specifi-cation.The inch-pound units shall apply unless the“M”designation of this specification is specified in the order.2.Referenced Documents2.1 ASTM Standards:3A450/A450M Specification for

15、n requested on the purchase order,a product analy-sis shall be made by the supplier from 1 tube per 250 pieces;when tubes are identified by heat,one tube per heat shall beanalyzed.The chemical composition thus determined shallconform to the requirements specified.8.2 If the original test for product
16、 analysis fails,retests oftwo additional lengths of flat-rolled stock,or tubes shall bemade.Both retests,for the elements in question,shall meet therequirements of the specification;otherwise all remainingmaterial in the heat or lot(Note 1)shall be rejected or,at theoption of the producer,each length of flat-rolled stock or tubemay be individually tested for acceptance.Lengths of flat-rolled stock or tubes which do not meet the requirements of thespecification shall be rejected.NOTE1A lot consis
