Mechanical Property Requirements8.1 Tensile, Yield, and Elongation:8.1.1 Product furnished under this specifica
30、tion shall con-form to the tensile, yield, and elongation requirements pre-scribed in Table 2, for the alloy specified in the orderinginformation, when tested in accordance with Test Methods E8.8.1.1.1 Only tensile, yield, or elongation test results shall bea basis for rejection based upon mechanica
31、l properties.8.2 Rockwell Hardness:8.2.1 Product furnished fromAlloy C63020 in TQ30 tempershall have a minimum hardness of 26 on the Rockwell C scalewhen tested in accordance with Test Methods E18.8.2.1.1 The approximate Rockwell hardness values givenare for general information and assistance in tes
32、ting and shallnot be used as a basis for product rejection.9. Other Requirements9.1 Nondestructive Testing:9.1.1 Unless otherwise agreed upon between the supplierand the purchaser, the pipe or tube shall be tested for defectseither in the final drawn, annealed, or specified temper or in thedrawn tem
33、per before the final anneal. Unless otherwise speci-fied, the manufacturer shall have the option of testing the pipeor tube by one of the following tests:9.1.2 Electromagnetic Examination (Eddy Current)Eachtube or pipe in nominal sizes from18 in. (3.2 mm) up to andincluding 212 in. (63.5 mm), regula
34、r and extra-strong, shall besubjected to an eddy-current test. Tests shall follow theprocedures of Practice E 243 except for the determination of“end effect.” The pipe or tube shall be passed through aneddy-current testing unit adjusted to detect an artificial defectof a size and shape defined as fo
35、llows:NOTE 3End effect is that length of the pipe or tube that travelsthrough the coil until the testing unit has stabilized and is able to detectflaws. The magnitude of the spike generated when an end passes throughthe test coils is such that it disrupts testing momentarily.9.1.2.1 Artificial Defec
36、tsRound bottom-notch standardswith a profile as defined in Practice E 243, rounded to thenearest 0.001 in. (0.025 mm) shall be 10 % of the specifiedwall thickness. Notch-depth tolerances shall be 60.0005 in.(0.013 mm). Alternatively, when a manufacturer uses speed-insensitive equipment that can sele
37、ct a maximum unbalancesignal, a maximum unbalance signal of 0.3 % shall be used.9.1.2.2 RetestingPipes or tubes that do not activate thesignaling device of the eddy-current tester shall be consideredas conforming to the requirements of this test. Lengths withdiscontinuities, indicated by the testing
38、 unit, at the option of themanufacturer, may be reexamined or retested to determinewhether the discontinuity is cause for rejection. Signals that arefound to have been caused by soil, moisture, or minormechanical damage shall not be cause for rejection, providedthe pipe or tube dimensions are still
39、within the prescribed limitsand the pipe or tube is suitable for its intended application.9.1.3 Pressure TestsEach pipe or tube selected in accor-dance with 13.3 shall withstand the pressure test of either9.1.3.1 or 9.1.3.2.9.1.3.1 Hydrostatic TestEach pipe or tube shall withstand,without showing ev
40、idence of leakage, an internal hydrostaticpressure sufficient to subject the material to a fiber stress of7000 psi (48 mPa). The pipe or tube need not be tested at ahydrostatic pressure of over 1000 psi (6.9 MPa) unless sospecified.At the option of the manufacturer, annealed pipe withwall thickness
41、up to 0.083 in. (2.11 mm), inclusive, may betested in the drawn condition, before annealing. Fiber stressshall be determined by the following equation for thin, hollowcylinders under tension:P 5 2St/D 2 0.8t! (1)where:P = hydrostatic pressure, psi (MPa);t = thickness of pipe or tube wall, in. (mm);D
42、 = 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 pressur-ized to a minimum of 60 psi (415 kPa), air for 5 s, withoutshowing evidence of leakage. The test method used shallpermit easy visual de
43、tection of any leakage, such as bysubmerging the tube under water or by pressure differentialmethod.10. Dimensions, Mass, and Permissible Variations10.1 General:10.1.1 The standard method of specifying wall thicknessshall be in decimal fractions of an inch.10.1.2 For the purpose of determining confo
44、rmance with thedimensional requirements prescribed in this specification, anymeasured value outside the specified limiting values for anydimension may be cause for rejection.10.1.3 Tolerances on a given tube may be specified withrespect to any two, but not all three, of the following: outsidediamete
45、r, inside diameter, wall thickness.NOTE 4Blank spaces in the tolerance tables indicate either that theproduct is not generally available or that no tolerances have beenestablished.10.2 DimensionsDimensions and theoretical weights ofnominal pipe sizes shall be in accordance with Table 3.10.3 Wall Thi
