29、 IIA TubesEach finished tube shall be subjected to the hydrostatic test, the pneumatic test, or the eddycurrent test at the manufacturers option.4.2.2 Class III TubesEach finished tube shall be subjected to the pneumatic test and the eddy current test. Tubes larger than112 in. (38.1 mm) in outside d

30、iameter may be subjected to the hydrostatic test in lieu of the pneumatic test at the manufacturersoption.5. Ordering Information5.1 It is the responsibility of the purchaser to specify all requirements that are necessary for material ordered under thisspecification. Examples of such requirements in

31、clude, but are not limited to the following:5.1.1 Alloy (Table 1),5.1.2 Class (see 4),5.1.3 Quantity (feet or number of lengths),5.1.4 Size (outside diameter and average wall thickness),5.1.5 Length (cut or random),5.1.6 CertificationState if certification or a report of test results is required,5.1

32、.7 Purchaser InspectionState which tests or inspections are to be witnessed,5.1.8 EndsPlain ends cut and deburred will be furnished, unless otherwise specified, and5.1.9 Samples for Product (Check) AnalysisState whether samples shall be furnished.6. Materials and Manufacture6.1 The tubes shall be ma

33、de from flat-rolled alloy by an automatic welding process with no addition of filler metal.6.2 Subsequent to welding and prior to final heat treatment, Class II and Class III tubes shall be cold worked either in both weldand base metal or in weld metal only. The method and amount of cold working may

34、 be specified by the purchaser. When colddrawn, the purchaser may specify the minimum amount of reduction in cross-sectional area or wall thickness, or both.6.3 All tubes shall be furnished in the solution annealed and descaled condition. When atmosphere control is used, descalingis not necessary.7.
