1、Designation:A694/A694M16Standard Specification forCarbon and Alloy Steel Forgings for Pipe Flanges,Fittings,Valves,and Parts for High-Pressure Transmission Service1This standard is issued under the fixed designation A694/A694M;the number immediately following the designation indicates the yearof ori
2、ginal 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 forged or rolled steel pipeflanges,forged
3、 fittings,valves,and parts suitable for use withhigh-strength transmission-service pipe.Included are flanges,fittings,and similar parts ordered either to dimensions specifiedby the purchaser or to ASME or MSS dimensional standardsreferenced in Section 2.1.2 Several grades of material,based on minimu
4、m yieldstrength requirements,are covered,as indicated in Table 1.1.3 Supplementary Requirements are provided.Supplemen-tary Requirement S1 is provided for use when purchaserapproval is required for repair welding.1.4 This specification is expressed in both inch-pound unitsand in SI units.However,unl
5、ess the order specifies theapplicable“M”specification designation(SI units),the mate-rial shall be furnished to inch-pound units.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 i
