1、Designation:A691/A691M09(Reapproved 2014)Standard Specification forCarbon and Alloy Steel Pipe,Electric-Fusion-Welded forHigh-Pressure Service at High Temperatures1This standard is issued under the fixed designation A691/A691M;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.Scope1.1 This specification2covers carbon and alloy steel pipe,electric-fusio
3、n-welded with filler metal added,fabricated frompressure-vessel-quality plate of several analyses and strengthlevels and suitable for high-pressure service at high tempera-tures.Heat treatment may or may not be required to attain thedesired mechanical properties or to comply with applicablecode requ
4、irements.Supplementary requirements are providedfor use when additional testing or examination is desired.1.2 The specification nominally covers pipe 16 in.400mm in outside diameter and larger with wall thicknesses up to3 in.75 mm inclusive.Pipe having other dimensions may befurnished provided it co
5、mplies 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 as listed inTable 1.1.3.2 Class designates the type of heat treatment performedin the manufacture of the pipe,whether the weld is radio-graphicall
