ASTM B546-04 pdf free.Standard Specification for Electric Fusion-Welded Ni-Cr-Co-Mo Alloy (UNS N06617),Ni-Fe-Cr-Si Alloys (UNS N08330 and UNS N08332), Ni-Cr-Fe-Al Alloy (UNS N06603), Ni-Cr-Fe Alloy (UNS N06025), and Ni-Cr-Fe-Si Alloy (UNS N06045) Pipe.
Two bend test specimens shall be taken transverselyfrom the pipe.One shall be subject to a face guided-bend testand the second to a root guided-bend test.The bend test shall be acceptable if no cracks or otherdefects exceeding !/s in. (3.2 mm) in any direction be present inthe weld metal or between the weld and the pipe metal afterbending. Cracks which originate along the edges of thespecimen during testing and that are less than 1/4 in. (6.4 mm)measured in any direction, shall not be considered.Any pipe that shows leaks duringhydrostatic testing shall be rejected.
Grain Size Annealed alloy UNS N08332 shall con-form to an average grain size of ASTM No. 5 or coarser.9.5 Annealing Temperature-Alloy UNS N08330 shall beannealed at 1900°F (1040°C) minimum. Alloy UNS N08332shall be annealed at 2100°F (1150°C) minimum. Alloy UNSN06617 shall be annealed at 2050°F (1121C) minimum.AlloyUNS N06025 shall be annealed at 2100°F (1150°C) minimum.Alloy UNS N06603 and UNS N06045 shall be annealed at2120°F (1160°C) minimum.Permissible Variations in Dimensions:The dimensions at any pointin a length of pipe shall not exceed the following:
Straightness,Using a 10 ft. (3.05m) straightedgeplaced so that both ends are in contact with the pipe; !s in. (3.2mm).The minimum wall thickness at anypoint in the pipe shall not be more than 0.01 in. (0.25 mm)under the nominal thickness.
Circumferentially welded joints of the same qualityas the longitudinal joints shall be permitted by agreementbetween the manufacturer and the purchaser.
Pipe shall be furnished with oxide removed.When final test treatment is performed in a protective atmosphere, descaling is not necessary.
Transverse tension and bend-test specimens shall betaken from the end of the finished pipe; the transverse tensionand bend-test specimens shall be flattened cold before finalmachining to size. As an alternative to the requirements of 13.1, the testspecimens may be taken from a test plate of the same materialas the pipe, which is attached to the end of the cylinder andwelded as a prolongation of the pipe longitudinal seam.13.3 Tension specimens shall be the full thickness of thematerial and shall be machined to the form and dimensionsshown for large diameter products in Specification B 775.13.4 The test specimens shall not be cut from the pipe or testplate until after final anneal.ASTM B546 pdf download.
