19、Temper7.1 Drawn Tempers, HThe tempers of drawn tube shall bedesignated as light-drawn (H55), drawn (H58), and hard-drawn(H80) (see Table 2). Light-drawn (bending) temper is used onlywhen a tube of some stiffness but yet capable of being bent isneeded. Drawn temper is for general purposes and is most

20、commonly used where there is no specific requirement for highstrength on the one hand or for bending qualities on the other.Hard-drawn temper is used only where there is need for a tubeas strong as is commercially feasible for the sizes indicated.For any combination of diameter and wall thickness no

21、tcovered under hard-drawn temper, the values given for drawntemper shall be used. Rectangular including square tubes shallnormally be supplied only in drawn (general-purpose) temper.When there is a need for light-drawn or hard-drawn tempersthese are to be supplied as agreed upon between the manufac-

22、turer and the purchaser.7.2 Annealed Tempers, OThe tempers of annealed tubeshall be designated as light anneal (O50) and soft anneal (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

23、 condition a minimum tensile strength of 40 ksi anda minimum yield strength of 12 ksi at 0.5 % extension under load, inwhich case the provisions for grain size and Rockwell hardness in 8.2 donot apply.8. Mechanical Properties8.1 Drawn TemperTube shall conform to the mechanicalproperties prescribed i

24、n Table 2. Tension tests are required fortubes with a wall thickness under 0.020 in. and for round tubeshaving an inside diameter under516 in. and for rectangularincluding square tubes having a major distance between insideparallel surfaces under316 in. The tension test for other sizes oftubes need

25、not be made except when indicated by the purchaserat the time of placing the order. A convenient method ofindicating that the tension test is required is to specify that“Test procedure T is required” (see 4.1.3). When agreementon the Rockwell hardness tests cannot be reached, the tensilestrength req

26、uirements of Table 2 shall be the basis for accep-tance or rejection.8.2 Annealed TemperTube shall conform to the grain sizeand Rockwell 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 withsta

27、nding in accordance with TestMethod B153 an expansion of the outside diameter in thefollowing amount:Outside Diameter, in.Expansion of OutsideDiameter, %34 and under 20Over34 15The expanded tube shall show no cracking or rupture visibleto the unaided eye.

32、times the wall thickness will pass over the tube freely through-out the flattened part.
