Therefore, eachsystem is to be used independently of the other.1.4 The following precautionary caveat pertains only to thetest method portion, Sections 11, 12, and 13 of th

8、is specifica-tion: This standard does not purport to address all of the safetyconcerns, if any, associated with its use.

General Requirements6.1 Material furnished to this specification shall conform tothe applicable requirements of the current edition of Specifi-cation A 530/

24、A 530M unless otherwise provided herein.7. Chemical Composition7.1 The steel shall conform to the requirements as tochemical composition prescribed in Table 1.8. Heat Analysis8.1 An analysis of each heat of steel shall be made by thesteel manufacturer to determine the percentages of the ele-ments sp

25、ecified in Section 7. If the secondary melting pro-cesses of 5.1 are employed, the heat analysis shall be obtainedfrom one remelted ingot or the product of one remelted ingotof each primary melt. The chemical composition thus deter-mined, or that determined from a product analysis made by themanufac

26、turer, if the latter has not manufactured the steel, shallbe reported to the purchaser or the purchasers representative,and shall conform to the requirements specified in Section 7.9. Product Analysis9.1 At the request of the purchaser, analyses of two pipesfrom each lot (see 20.1) shall be made by

27、the manufacturerfrom the finished pipe. The results of these analyses shall bereported to the purchaser or the purchasers representative andshall conform to the requirements specified in Section 7.9.2 If the analysis of one of the tests specified in 9.1 doesnot conform to the requirements specified

28、in Section 7,analyses shall be made on additional pipes of double theoriginal number from the same lot, each of which shallconform to requirements specified.10. Tensile Requirements10.1 The material shall conform to the requirements as totensile properties given in Table 2.11. Bending Requirements11

29、.1 For pipe NPS 2 DN 50 and under, a sufficient lengthof pipe shall stand being bent cold through 90 around acylindrical mandrel, the diameter of which is twelve times theoutside diameter (as shown in ASME B 36.10M) of the pipe,without developing cracks. When ordered for close coiling, thepipe shall

30、 stand being bent cold through 180 around acylindrical mandrel, the diameter of which is eight times theoutside diameter (as shown in ASME B 36.10M) of the pipe,without failure.11.2 For pipe whose diameter exceeds 25 in. 635 mm andwhose diameter to wall thickness ratio, where the diameter towall thi

31、ckness ratio is the specified outside diameter divided bythe nominal wall thickness, is 7.0 or less, the bend test shall beconducted. The bend test specimens shall be bent at roomtemperature through 180 with the inside diameter of the bendbeing 1in. 25 mm without cracking on the outside portion ofth

32、e bent portion.Example: For 28 in. 711 mm diameter 5.000 in. 127 mmthick pipe the diameter to wall thickness ratio = 28/5 = 5.6711/127 = 5.6.TABLE 1 Chemical RequirementsComposition, %Grade A Grade B Grade CCarbon, maxA0.25 0.30 0.35Manganese 0.270.93 0.291.06 0.291.06Phosphorus, max 0.035 0.035 0.0

Flattening Tests12.1 Although testing is not required, pipe shall be capableof meeting the flattening test requirements of SupplementaryRequirement S3, if tested.13.

35、Hydrostatic Test13.1 Except as allowed by 13.2, 13.3, and 13.4, each lengthof pipe shall be subjected to the hydrostatic test withoutleakage through the pipe wall.13.2 As an alternative to the hydrostatic test at the option ofthe manufacturer or where specified in the purchase order, itshall be perm

36、issible for the full body of each pipe to be testedwith a nondestructive electric test described in Section 14.13.3 Where specified in the purchase order, it shall bepermissible for pipe to be furnished without the hydrostatic testand without the nondestructive electric test in Section 14;inthis cas

37、e, each length so furnished shall include the mandatorymarking of the letters “NH.” It shall be permissible for pipemeeting the requirements of 13.1 or 13.2 to be furnished wherepipe without either the hydrostatic or nondestructive electrictest has been specified in the purchase order; in this case,

38、 suchpipe need not be marked with the letters “NH.” Pipe that hasfailed either the hydrostatic test of 13.1 or the nondestructiveelectric test of 13.2 shall not be furnished as “NH” pipe.13.4 Where the hydrostatic test and the nondestructiveelectric test are omitted and the lengths marked with the l

39、etters“NH,” the certification, where required, shall clearly state “NotHydrostatically Tested,” and the letters “NH” shall be ap-pended to the product specification number and material gradeshown on the certification.14. Nondestructive Electric Test14.1 As an alternative to the hydrostatic test at t

40、he option ofthe manufacturer or where specified in the purchase order as analternative or addition to the hydrostatic test, the full body ofeach pipe shall be tested with a nondestructive electric test inaccordance with Practice E 213, E 309,orE 570. In such cases,the marking of each length of pipe

41、so furnished shall includethe letters “NDE.” It is the intent of this nondestructive electrictest to reject pipe with imperfections that produce test signalsequal to or greater than that produced by the applicablecalibration standard.14.2 Where the nondestructive electric test is performed, thelengt

42、hs shall be marked with the letters “NDE.” The certifica-tion, where required, shall state “Nondestructive ElectricTested” and shall indicate which of the tests was applied. Also,the letters “NDE” shall be appended to the product specifica-tion number and material grade shown on the certification.14

43、.3 The following information is for the benefit of the userof this specification:14.3.1 The reference standards defined in 14.4 through 14.6are convenient standards for calibration of nondestructivetesting equipment. The dimensions of such standards are not tobe construed as the minimum sizes of imp

44、erfections detectableby such equipment.14.3.2 The ultrasonic testing referred to in this specificationis capable of detecting the presence and location of significantlongitudinally or circumferentially oriented imperfections:however, different techniques need to be employed for thedetection of such

45、differently oriented imperfections. Ultrasonictesting is not necessarily capable of detecting short, deepimperfections.TABLE 2 Tensile RequirementsGrade A Grade B Grade CTensile strength, min, psi MPaYield strength, min, psi MPa48 000 33030 000 20560 000 41535 000 24070 000 48540 000 275Longitu-dina
