ASTM A587:2019 pdf download.Standard Specification for Electric-Resistance-Welded Low-Carbon Steel Pipe for the Chemical lndustry.
8.5 Undercut flash must be smoothly blended into the pipe wall.
8.6 The intent of the flash conditions as prescribed in 8.3.
8.4. and 8.5 is to oNain a surface contour suitable for hanging.
9. Number of Tests
9.1 Two tensile tests as specified in 6,1 shall be made from each heat.
9.2 The flattening test as specified in 6.2 shall be made on two lengths of pipe from each lot of 250 lengths or fraction thereof.
9.3 The reverse flattening test specified in 6.3 shall he made on I length of pipe from each lot of 250 lengths or fraction thereof.
9.4 The flange test as specified in 6.4 shall be made on specimens from 2 lengths of pipe from each lot of 250 lengths or fraction thereof.
10. Retests
10.1 If the results of the mechanical tests of any heat or lot do not conform to the requirements specified. relests may be made on additional pipe of double the original number from the same heat or lot, each of which shall conform to the requirements specified.
11. Retreatmcnl
11.1 If a heat or lot fails to conform to the test requirements. that heat or lot may be reheat treated and resubmitted for tests. Not more than one reheat treatment shall be permitted.
12. Test Speciniens and Niethods of Testing
12.1 The test specimens and the tests required by this specification shall conform to those described in Test Methods and [)elinitions A370.
12.2 Test specimens shall he taken from the ends of finished pipe prior to upsetting. swaging, expanding, or other forming operations, or being cut to length. They shall be smooth on the ends and free from burrs and flaws.
12.3 If any test specimen shows flaws or defective machining. it may be discarded and another specimen substituted.
13. ondestructie Test
13.1 The nondestructive test shall be made instead of the hydrostatic test.
13.1.1 The test shall provide a 3 inspection for sites up to and including 3½ in. (88.9 mm) outside diameter.
13.1.2 For pipe larger than 3½ in. (88.9 mm) outside diameter, nondestructive inspection of the weld and heat aIl’ected tone is required.
13.2 Each pipe shall be tested with a nondestructive lest in accordance with Practices E213. E273. E309. or E570. Except as provided in 13.6.2. it is the intent of this test to reject pipe with imperfections that produce test signals equal to or greater than that of the calibration standard. In order to accommodate the various types of nondestructive testing equipment.
