Workmanship, Finish and Appearance
1.The pipe manufacturer shall explore a sufficient num- ber of visual surface imperfections to provide reasonable assurance that they have been properly evaluated with respect to depth.
2.Surface imperfections that penetrate more than 12½ % of the nominal wall thickness or encroach on the minimum wall thickness shall be considered defects.
2.Surface imperfections that penetrate more than 12½ % of the nominal wall thickness or encroach on the minimum wall thickness shall be considered defects.
3.The pipe manufacturer shall remove by grinding the following:
Mechanical marks, abrasions and pits, any of which imperfections are deeper than 1⁄16 in. [1.6 mm], and
Visual imperfections commonly referred to as scabs, seams, laps, tears, or slivers found by exploration
4.When imperfections or defects are removed by grind- ing, a smooth curved surface shall be maintained, and the wall thickness shall not be decreased below that permitted by this specification. The outside diameter at the point of grinding may be reduced by the amount so removed.
5.The finished pipe shall be reasonably straight.
4.When imperfections or defects are removed by grind- ing, a smooth curved surface shall be maintained, and the wall thickness shall not be decreased below that permitted by this specification. The outside diameter at the point of grinding may be reduced by the amount so removed.
5.The finished pipe shall be reasonably straight.
Mechanical Testing
The impact test is not required for Grade 11.
The impact test is not required for Grade 11.
Sampling—For mechanical testing
1.Transverse or Longitudinal Tensile Test and Flattening Test
2..Hydrostatic Test—Each length of pipe shall be sub- jected to the hydrostatic test.
Hydrostatic or Nondestructive Electric Test
Nondestructive Electric Test—Nondestructive electric tests shall be in accordance with Specification A 999/A 999M, with the following addition:
If the test signals were produced by visual imperfec- tions (listed in D), the pipe may be accepted based on visual examination, provided the imperfection is less than 0.004 in. (0.1 mm) or 12½ % of the specified wall thickness(whichever is greater).
