1、Designation:A671/A671M16aStandard Specification forElectric-Fusion-Welded Steel Pipe for Atmospheric andLower Temperatures1This standard is issued under the fixed designation A671/A671M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision
2、,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 electric-fusion-welded steelpipe with filler metal added,fabricated from pressure
3、vesselquality plate of several analyses and strength levels andsuitable for high-pressure service at atmospheric and lowertemperatures.Heat treatment may or may not be required toattain the desired properties or to comply with applicable coderequirements.Supplementary requirements are provided forus
4、e when additional testing or examination is desired.1.2 The specification nominally covers pipe 16 in.400mm in outside diameter or larger and of14in.6 mm wallthickness or greater.Pipe having other dimensions may befurnished provided it complies with all other requirements ofthis specification.1.3 Se
5、veral grades and classes of pipe are provided.1.3.1 Grade designates the type of plate used as listed in 5.1.1.3.2 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
