Ordering Information5.1 It is the responsibility of the purchaser to specify all requirements that are necessary for the safe and satisfactoryperformance of material ordered under this specification. Examples of such requirements include, but are not limited to, thefollowing:5.1.1 Al
17、loy name or UNS number,5.1.2 ASTM designation,5.1.3 Dimensions:5.1.3.1 Pipe size,5.1.3.2 Length (specific or random),5.1.4 Class (see Section 3),5.1.5 Grade if UNS N06625 is specified. If neither grade of N06625 is specified, grade 1 will be supplied.5.1.6 Quantity (feet or number of pieces),5.1.7 C

19、r must so state indicating which tests or inspections are to be witnesses.6. Material and Manufacture6.1 Pipe shall be made from flat-rolled alloy by an automatic welding process with no addition of filler metal. Subsequent towelding and prior to final annealing, the material shall be cold-worked in
20、 either the weld metal only or both weld and base metal.6.2 Pipe shall be furnished with oxide removed. When bright annealing is used, descaling is not necessary.7. Chemical Composition7.1 The material shall conform to the composition limits specified in Table 1. One test per lot shall be performed.
21、7.2 If a product (check) analysis is performed by the purchaser, the material shall conform to the product (check) analysisvariations per Specification B880.8. Mechanical Properties and Other Requirements8.1 Mechanical PropertiesThe material shall conform to the mechanical properties specified in Ta

(102 mm) in length shall be capable of withstanding, without cracking,flattening under a load applied gradually at room temperature until the distance between the platens is five times the wall thickness
23、.The weld shall be positioned 90 from the direction of the applied flattening force. One pipe per lot shall be examined.8.2.1 Superficial ruptures resulting from surface imperfections shall not be a cause for rejection.8.3 Transverse Guided Bend Test:TABLE 1 Chemical RequirementsComposition Limits,

26、 bend specimens shall be taken transversely from pipe or the test specimens may be taken from a test plate of the same materialand heat as pipe, which is attached to the end of the cylinder and welded as a prolongation of the pipe longitudinal seam. Exceptas provided in 8.3.2, one shall be subjected
27、 to a face guided bend and a second to a root guided bend test. One specimen shall bebent with the inside surface of the pipe against the plunger and the other with the outside surface of the pipe against the plunger.Guided bend test specimens shall be prepared and tested in accordance with Section
28、IX, Part QW 160 of the ASME Boiler andPressure Vessel Code and shall be one of the types shown in QW462.2 and QW462.3 of that code. One bend test (two bendspecimens) per lot shall be examined.8.3.2 For specified wall thicknesses 38 in. (9.5 mm) and over, but less than 34 in. (19 mm) side bend tests
29、may be made insteadof the face and root bend tests. For specified wall thicknesses 34 in. (19) and over, both specimens shall be subjected to the sidebend tests. Side bend specimens shall be bent so that one of the side surfaces becomes the convex surface of the bend specimen.8.3.3 The bend test sha
30、ll be acceptable if no cracks or other defects exceeding 18 in. (3 mm) in any direction be present in theweld metal or between the weld and the pipe or plate metal after bending.

Nondestructive Testing9.1 Class 1Each piece in each lot shall be subjected to one of the following four tests: hydrostatic, pneumatic (air underwater),eddy current, or ultrasonic.9.2 Class 2Each piece in each lot shall be subjected to a leak test and an electric t
32、est as follows:9.2.1 Leak TestHydrostatic or pneumatic (air underwater).9.2.2 Electric TestEddy current or ultrasonic.9.3 The manufacturer shall have the option to test to Class 1 or 2 and select the nondestructive test methods, if not specifiedby the purchaser.10.
