Other Requirements9.1 Nondestructive Testing:9.1.1 Unless otherwise agreed upon between the supplier and

40、the purchaser, the pipe or tube shall be tested for defects eitherin the final drawn, annealed, or specified temper or in the drawn temper before the final anneal. Unless otherwise specified, themanufacturer shall have the option of testing the pipe or tube by one of the following tests:9.1.2 Electr

41、omagnetic Examination (Eddy Current)Each tube or pipe in nominal sizes from 18 in. (3.2 mm) up to andincluding 212 in. (63.5 mm), regular and extra-strong, shall be subjected to an eddy-current test. Tests shall follow the proceduresof Practice E243 except for the determination of “end effect.” The

42、pipe or tube shall be passed through an eddy-current testing unitadjusted to detect an artificial defect of a size and shape defined as follows:NOTE 4End effect is that length of the pipe or tube that travels through the coil until the testing unit has stabilized and is able to detect flaws. Themagn

43、itude of the spike generated when an end passes through the test coils is such that it disrupts testing momentarily.9.1.2.1 Artificial DefectsRound bottom-notch standards with a profile as defined in Practice E243, rounded to the nearest0.001 in. (0.025 mm) shall be 10 % of the specified wall thickn

44、ess. Notch-depth tolerances shall be 60.0005 in. (0.013 mm).Alternatively, when a manufacturer uses speed-insensitive equipment that can select a maximum unbalance signal, a maximumunbalance signal of 0.3 % shall be used.9.1.2.2 RetestingPipes or tubes that do not activate the signaling device of th

45、e eddy-current tester shall be considered asconforming to the requirements of this test. Lengths with discontinuities, indicated by the testing unit, at the option of themanufacturer, may be reexamined or retested to determine whether the discontinuity is cause for rejection. Signals that are foundt

46、o have been caused by soil, moisture, or minor mechanical damage shall not be cause for rejection, provided the pipe or tubedimensions are still within the prescribed limits and the pipe or tube is suitable for its intended application.9.1.3 Pressure TestsEach pipe or tube selected in accordance wit

47、h 13.313.1.3 shall withstand the pressure test of either 9.1.3.1or 9.1.3.2.9.1.3.1 Hydrostatic TestEach pipe or tube shall withstand, without showing evidence of leakage, an internal hydrostaticpressure sufficient to subject the material to a fiber stress of 7000 psi (48 mPa). The pipe or tube need

48、not be tested at a hydrostaticpressure of over 1000 psi (6.9 MPa) unless so specified. At the option of the manufacturer, annealed pipe with wall thickness upto 0.083 in. (2.11 mm), inclusive, may be tested in the drawn condition, before annealing. Fiber stress shall be determined by thefollowing eq

49、uation for thin, hollow cylinders under tension:P 52St/D 20.8t! (1)where:P = hydrostatic pressure, psi (MPa);t = thickness of pipe or tube wall, in. (mm);D = outside diameter of the pipe or tube, in. (mm); andS = allowable fiber stress of the material, psi (MPa).9.1.3.2 Pneumatic TestEach pipe or tube shall be pressurized to a minimum of 60 psi (415 kPa), air for 5 s, without showingevidence of leakage. The test method used shall permit easy visual detection of any leakage, such as by submerging the tube underwater or by pressure differential met
