Designation: A 671 – 06 Standard Specification for Electric-Fusion-Welded Steel Pipe for Atmospheric and Lower Temperatures1 This standard is issued under the fixed designation A 671; the number immediately following the designation indicates the year of original 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 (e) indicates an editorial change since the last revision or reapproval. 1. Scope* 1.1 This specification2 covers electric-fusion-welded steel pipe with filler metal added, fabricated from pressure vessel quality plate of several analyses and strength levels and suitable for high-pressure service at atmospheric and lower temperatures. Heat treatment may or may not be required to attain the desired properties or to comply with applicable code requirements. Supplementary requirements are provided for use when additional testing or examination is desired. 1.2 The specification nominally covers pipe 16 in. (405 mm) in outside diameter or larger and of 1⁄4 in. (6.4 mm) wall thickness or greater. Pipe having other dimensions may be furnished provided it complies with all other requirements of this specification. 1.3 Several 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 performed during manufacture of the pipe, whether the weld is radio- graphically examined, and whether the pipe has been pressure tested as listed in 1.3.3. 1.3.3 Class designations are as follows (Note 1): Class Heat Treatment on Pipe Radiography, see Section Pressure Test, see: 10 none none none 11 none 9 none 12 none 9 8.3 13 none none 8.3 20 stress relieved, see 5.3.1 none none 21 stress relieved, see 5.3.1 9 none 22 stress relieved, see 5.3.1 9 8.3 23 stress relieved, see 5.3.1 none 8.3 30 normalized, see 5.3.2 none none 31 normalized, see 5.3.2 9 none 32 normalized, see 5.3.2 9 8.3 33 normalized, see 5.3.2 none 8.3 40 normalized and tempered, see 5.3.3 none none 41 normalized and tempered, see 5.3.3 9 none 42 normalized and tempered, see 5.3.3 9 8.3 43 normalized and tempered, see 5.3.3 none 8.3 50 quenched and tempered, see 5.3.4 none none 51 quenched and tempered, see 5.3.4 9 none 52 quenched and tempered, see 5.3.4 9 8.3 53 quenched and tempered, see 5.3.4 none 8.3 60 normalized and precipitation heat treated none none 61 normalized and precipitation heat treated 9 none 62 normalized and precipitation heat treated 9 8.3 63 normalized and precipitation heat treated none 8.3 70 quenched and precipitation heat treated none none 71 quenched and precipitation heat treated 9 none 72 quenched and precipitation heat treated 9 8.3 73 quenched and precipitation heat treated none 8.3 NOTE 1—Selection of materials should be made with attention to temperature of service.

The results of the analyses shall be reported to the purchaser. 8. Mechanical Requirements 8.1 Tension Test: 8.1.1 Requirements——Transverse tensile properties of the welded joint shall meet the minimum requirements for ultimate tensile strength of the specified plate material. In addition for Grades CD and CJ, when these are of Class 3x, 4x, or 5x, and Grade CP of Class 6x and 7x, the transverse tensile properties of the base plate shall be determined on specimens cut from the heat-treated pipe. These properties shall meet the mechanical test requirements of the plate specification. 8.1.2 Number of Tests—One test specimen of weld metal and one specimen of base metal, if required by 8.1.1, shall be made and tested to represent each lot of finished pipe. 8.1.3 Test Specimen Location and Orientation—The test specimens shall be taken transverse to the weld at the end of the finished pipe and may be flattened cold before final machining to size. 8.1.4 Test Method—The test specimen shall be made in accordance with QW-150 in Section IX of the ASME Boiler and Pressure Vessel Code. The test specimen shall be tested at room temperature in accordance with Test Methods and Defi- nitions A 370. 8.2 Transverse Guided Weld Bend Test: 8.2.1 Requirements—The bend test shall be acceptable if no cracks or other defects exceeding 1⁄8 in. (3.2 mm) in any direction are present in the weld metal or between the weld and the base metal after bending. Cracks that originate along the edges of the specimen during testing, and that are less than 1⁄4 in. (6.4 mm) measured in any direction shall not be considered. 8.2.2 Number of Tests—One test (two specimens) shall be made to represent each lot of finished pipe. 8.2.3 Test Specimen Location and Orientation—Two bend test specimens shall be taken transverse to the weld at the end of the finished pipe. As an alternative, by agreement between the purchaser and the manufacturer, the test specimens may be taken from a test plate of the same material as the pipe, the test plate being attached to the end of the cylinder and welded as a prolongation of the pipe longitudinal seam. 8.2.4 Test Method—The test requirements of A 370, S9.1.7 shall be met. For wall thicknesses over 3⁄8 in. (9.5 mm) but less than 3⁄4 in. (19.0 mm) side-bend tests may be made instead of the face and root-bend tests. For wall thicknesses 3⁄4 in. and over both specimens shall be subjected to the side-bend test. 8.3 Pressure Test—Classes X2 and X3 pipe shall be tested in accordance with Specification A 530/A 530M, Section 6. 9. Radiographic Examination 9.1 The full length of each weld of Classes X1 and X2 shall be radiographically examined in accordance with and meet the requirements of ASME Boiler and Pressure Vessel Code, Section VIII, Paragraph UW–51. 9.2 Radiographic examination may be performed prior to heat treatment. 10. Rework 10.1 Elimination of Surface Imperfections—Unacceptable surface imperfections shall be removed by grin
