1、Designation:A672/A672M14Standard Specification forElectric-Fusion-Welded Steel Pipe for High-Pressure Serviceat Moderate Temperatures1This standard is issued under the fixed designation A672/A672M;the number immediately following the designation indicates the yearof original adoption or,in the case
2、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 specification2covers steel pipe:electric-fusion-welded with filler metal added,fabricated fr
3、om pressure-vesselquality plate of any of several analyses and strength levels andsuitable for high-pressure service at moderate temperatures.Heat treatment may or may not be required to attain the desiredproperties or to comply with applicable code requirements.Supplementary requirements are provid
4、ed for use when addi-tional testing or examination is desired.1.2 The specification nominally covers pipe 16 in.400mm in outside diameter or larger with wall thicknesses up to3 in.75 mm,inclusive.Pipe having other dimensions may befurnished provided it complies with all other requirements ofthis spe
5、cification.1.3 Several grades and classes of pipe are provided.1.3.1 Grade designates the type of plate used.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
