Temper7.1 Drawn Tempers, HThe tempers of drawn tube shall bedesignated as light-drawn (H55), drawn (H58), and hard-drawn(H80) (s
19、ee Table 2). Light-drawn (bending) temper is usedonly when a tube of some stiffness but yet capable of beingbent is needed. Drawn temper is for general purposes and ismost commonly used where there is no specific requirement forhigh strength on the one hand or for bending qualities on theother. Hard
20、-drawn temper is used only where there is need fora tube as strong as is commercially feasible for the sizesindicated. For any combination of diameter and wall thicknessnot covered under hard-drawn temper, the values given fordrawn temper shall be used. Rectangular including squaretubes shall normal
21、ly be supplied only in drawn (generalpurpose) temper. When there is a need for light-drawn orhard-drawn tempers these are to be supplied as agreed uponbetween the manufacturer and the purchaser.7.2 Annealed Tempers, OThe tempers of annealed tubeshall be designated as light anneal (O50) and soft anne
22、al (O60)(Table 3).NOTE 1Tube of Copper Alloy UNS No. C23000, when specified tomeet the requirements of the ASME Boiler and Pressure Vessel Code, shallhave in the annealed condition a minimum tensile strength of 275 MPaand a minimum yield strength of 80 MPa at 0.5 % extension under load,in which case
23、 the provisions for grain size and Rockwell hardness in 8.2do not apply.8. Mechanical Properties8.1 Drawn TemperTube shall conform to the mechanicalproperties prescribed in Table 2. Tension tests are required fortubes with a wall thickness under (0.508 mm) and for roundtubes having an inside diamete
24、r under 8.0 mm and forrectangular including square tubes having a major distancebetween inside parallel surfaces under 5.0 mm. The tension testfor other sizes of tubes need not be made except whenindicated by the purchaser at the time of placing the order. Aconvenient method of indicating that the t
25、ension test is requiredis to specify that “Test procedure T is required” (see 4.1.3).When agreement on the Rockwell hardness tests cannot bereached, the tensile strength requirements of Table 2 shall bethe basis for acceptance or rejection.8.2 Annealed TemperTube shall conform to the grain sizeand R
26、ockwell hardness limits prescribed in Table 3.9. Expansion Test for Round Tube9.1 Tube ordered in the annealed (O) condition, selected fortest, shall be capable of withstanding in accordance with TestMethod B153 an expansion of the outside diameter by thefollowing amount:Outside Diameter, mmExpansio

30、ure visibleto the unaided eye. Tube ordered in the drawn (H) condition isnot subject to this test.NOTE 2The term “unaided eye,” as used herein, permits the use ofcorrective spectacles necessary to obtain normal vision.9.2 As an alternative to the expansion test for tube over 102mm in diameter in the
31、 annealed condition, a section 102 mm inlength shall be cut from the end of one of the lengths for aflattening test. This 102-mm test specimen shall be flattened sothat a gage set at three times the wall thickness will pass overthe tube freely throughout the flattened part. The tube so testedshall d
32、evelop no cracks or flaws visible to the unaided eye(Note 2) as a result of this test. In making the flattening test, theelements shall be slowly flattened by one stroke of the press.9.3 Drawn temper tube shall not be required to withstandthese tests.10. Mercurous Nitrate Test10.1 WarningMercury is
33、a definite health hazard. Useequipment for the detection and removal of mercury vapor.Wear rubber gloves when conductiong the test.10.2 When specifically required, test specimens 152 mm inlength of both annealed and drawn tempers shall withstand,after proper cleaning, an immersion for 30 min without
34、cracking in the standard mercurous nitrate solution prescribedin Test Method B154. Immediately after removal from thesolution, the specimen shall be wiped free of excess mercuryand examined for cracks.11. Nondestructive Testing11.1 Unless nondestructive testing has been waived, tubesshall be subject
35、ed to a nondestructive test. The manufacturershall select the nondestructive test that is most suitable for thetube size and the application.11.1.1 Eddy-current testing is the standard nondestructivetest, and all tubes of appropriate size shall be eddy-currenttested in accordance with 11.2.11.1.2 Tu
36、bes that are not of a size suitable for eddy-currenttest capabilities shall be tested by the hydrostatic test asdescribed in 11.3.1, or by the pneumatic test as described in11.3.2.11.2 Eddy-Current TestEach tube up to 79 mm in outsidediameter shall be subjected to an eddy-current test. Testingshall
37、follow the procedure of Practice E243, except thedetermination of “end effect” is not required. Tubes shall bepassed through an eddy-current test unit adjusted to provideinformation on the suitability of the tube for the intendedapplication.TABLE 2 Mechanical Property Requirements of Drawn Temper Tu
