20、idediameter18 in. (3 mm) and larger and with wall thickness of0.015 in. (0.38 mm) and over shall be tested by the manufac-turer to an internal hydrostatic pressure of 1000 psi (6.9 MPa)provided that the fiber stress calculated in accordance with thefollowing equation does not exceed the allowable fi

21、ber stress S,indicated as follows:P 5 2St/D (1)where:P = hydrostatic test pressure, psi (or MPa),S = allowable fiber stress, for material in the condition(temper) furnished as follows: Cold worked annealed:30 000 psi (242 MPa)t = minimum wall thickness, in. (or mm), equal to thespecified nominal wal

22、l minus the permissible minuswall tolerance, or the specified minimum wall thick-ness, and,D = outside diameter of the pipe or tube, in. (or mm).8.1.1 When so agreed upon by the manufacturer and thepurchaser, pipe or tube may be tested to 112 times theallowable fiber stress given in 8.1.8.2 Pneumati

23、c Test:8.2.1 With no foreign material or moisture on the internalsurface, pressurize the tube internally to 150 psi (1034 Pa)minimum with uncontaminated compressed air while submerg-ing it in water of a clarity that permits unobstructed examina-tion of the tube.8.2.2 The tube shall be well-lighted,

24、preferably by under-water illumination.8.2.3 Correct any evidence of air leakage of the pneumaticcouplings prior to testing.8.2.4 After holding the pressure for not less than 5 s after thesurface of the water has become calm, inspect the entire lengthof the tube.8.3 Nondestructive Electric Test:8.3.

25、1 Test each tube with a nondestructive electric test inaccordance with Practice E426. It is the intent of this test toreject tube containing injurious defects.8.3.2 The calibration tube shall contain, at the option of theproducer, either of the following discontinuities to establish aminimum sensiti

26、vity level for rejection.8.3.3 Drilled Hole Drill a hole not larger than 0.031 in.(0.79 mm) diameter radially and completely through the tubewall, taking care to avoid distortion of the tube while drilling.8.3.4 Transverse Tangential NotchUsing a round tool orfile with a14 in. (6.4 mm) diameter, fil
