3、pecification2covers seamless carbon steel pipe forhigh-temperature service (Note 1)inNPS18 to NPS 48 DN 6to DN 1200 (Note 2) inclusive, with nominal (average) wallthickness as given in ASME B 36.10M. It shall be permissibleto furnish pipe having other dimensions provided such pipecomplies with all o
4、ther requirements of this specification. Pipeordered under this specification shall be suitable for bending,flanging, and similar forming operations, and for welding.When the steel is to be welded, it is presupposed that a weldingprocedure suitable to the grade of steel and intended use orservice wi
5、ll be utilized.NOTE 1It is suggested, consideration be given to possible graphitiza-tion.NOTE 2The dimensionless designator NPS (nominal pipe size) DN(diameter nominal) has been substituted in this standard for suchtraditional terms as “nominal diameter,” “size,” and “nominal size.”1.2 Supplementary
6、 requirements of an optional nature areprovided for seamless pipe intended for use in applicationswhere a superior grade of pipe is required. These supplemen-tary requirements call for additional tests to be made and whendesired shall be so stated in the order.1.3 The values stated in either SI unit
7、s or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.4 The following precauti

20、.1.14 Special requirements.4. Process4.1 The steel shall be killed steel, with the primary meltingprocess being open-hearth, basic-oxygen, or electric-furnace,possibly combined with separate degassing or refining. Ifsecondary melting, using electroslag remelting or vacuum-arcremelting is subsequentl
21、y employed, the heat shall be definedas all of the ingots remelted from a single primary heat.4.2 Steel cast in ingots or strand cast is permissible. Whensteels of different grades are sequentially strand cast, identifi-cation of the resultant transition material is required. Theproducer shall remov
22、e the transition material by any estab-lished procedure that positively separates the grades.4.3 For pipe NPS 112 DN 40 and under, it shall bepermissible to furnish hot finished or cold drawn.4.4 Unless otherwise specified, pipe NPS 2 DN 50 andover shall be furnished hot finished. When agreed uponbe
23、tween the manufacturer and the purchaser, it is permissibleto furnish cold-drawn pipe.5. Heat Treatment5.1 Hot-finished pipe need not be heat treated. Cold-drawnpipe shall be heat treated after the final cold draw pass at atemperature of 1200 F (650 C) or higher.6. General Requirements6.1 Material f
24、urnished to this specification shall conform tothe applicable requirements of the current edition of Specifi-cation A 530/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
25、 An analysis of each heat of steel shall be made by thesteel manufacturer to determine the percentages of the ele-ments specified 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 e
26、ach primary melt. The chemical composition thus deter-mined, or that determined from a product analysis made by themanufacturer, 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
27、 7.9. Product Analysis9.1 At the request of the purchaser, analyses of two pipesfrom each lot (see 20.1) shall be made by the manufacturerfrom the finished pipe. The results of these analyses shall bereported to the purchaser or the purchasers representative andshall conform to the requirements spec
28、ified in Section 7.9.2 If the analysis of one of the tests specified in 9.1 doesnot conform to the requirements specified 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 Requireme
29、nts10.1 The material shall conform to the requirements as totensile properties given in Table 2.11. Bending Requirements11.1 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
30、 diameter (as shown in ASME B 36.10M) of the pipe,without developing cracks. When ordered for close coiling, thepipe shall 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.1
31、1.2 For pipe whose diameter exceeds 25 in. 635 mm andwhose diameter to wall thickness ratio, where the diameter towall thickness 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 roo
32、mtemperature through 180 with the inside diameter of the bendbeing 1 in. 25 mm without cracking on the outside portion ofthe 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 RequirementsComposi

Flattening Tests12.1 Although testing is not
35、 required, pipe shall be capableof meeting the flattening test requirements of SupplementaryRequirement S3, if tested.13. 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 alte
36、rnative to the hydrostatic test at the option ofthe manufacturer or where specified in the purchase order, itshall be permissible 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
37、for pipe to be furnished without the hydrostatic testand without the nondestructive electric test in Section 14;inthis case, 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 where
38、pipe without either the hydrostatic or nondestructive electrictest has been specified in the purchase order; in this case, 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 “
39、NH” pipe.13.4 Where the hydrostatic test and the nondestructiveelectric test are omitted and the lengths marked with the letters“NH,” the certification, where required, shall clearly state “NotHydrostatically Tested,” and the letters “NH” shall be ap-pended to the product specification number and ma
40、terial gradeshown on the certification.14. Nondestructive Electric Test14.1 As an alternative to the hydrostatic test at the 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 nonde
41、structive electric test inaccordance with Practice E 213, E 309,orE 570. In such cases,the marking of each length of pipe 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 t
42、han that produced by the applicablecalibration standard.14.2 Where the nondestructive electric test is performed, thelengths 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
43、,the letters “NDE” shall be appended to the product specifica-tion number and material grade shown on the certification.14.3 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 calibrati
44、on of nondestructivetesting equipment. The dimensions of such standards are not tobe construed as the minimum sizes of imperfections detectableby such equipment.14.3.2 The ultrasonic testing referred to in this specificationis capable of detecting the presence and location of significantlongitudinal
45、ly or circumferentially oriented imperfections:however, different techniques need to be employed for thedetection of such differently oriented imperfections. Ultrasonictesting is not necessarily capable of detecting short, deepimperfections.TABLE 2 Tensile RequirementsGrade A Grade B Grade CTensile
