Scope
3、*1.1 This specification2 covers seamless carbon steel pipe for high-temperature service (Note 1) in NPS 18 to NPS 48 DN 6 toDN 1200 (Note 2) inclusive, with nominal (average) wall thickness as given inASME B 36.10M. It shall be permissible to furnishpipe having other dimensions provided such pipe co
4、mplies with all other requirements of this specification. Pipe ordered under thisspecification shall be suitable for bending, flanging, and similar forming operations, and for welding. When the steel is to bewelded, it is presupposed that a welding procedure suitable to the grade of steel and intend
5、ed use or service will be utilized.NOTE 1It is suggested, consideration be given to possible graphitization.NOTE 2The dimensionless designator NPS (nominal pipe size) DN (diameter nominal) has been substituted in this standard for such traditionalterms as “nominal diameter,” “size,” and “nominal siz
6、e.”1.2 Supplementary requirements of an optional nature are provided for seamless pipe intended for use in applications where asuperior grade of pipe is required. These supplementary requirements call for additional tests to be made and when desired shallbe so stated in the order.1.3 The values stat
7、ed in either SI units or inch-pound units are to be regarded separately as standard. The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.1.4

30、.6. General Requirements6.1 Material furnished to this specification shall conform to the applicable requirements of the current edition of SpecificationA530/A530M unless otherwise provided herein.7. Chemical Composition7.1 The steel shall conform to the requirements as to chemical composition presc
31、ribed in Table 1.8. Heat Analysis8.1 An analysis of each heat of steel shall be made by the steel manufacturer to determine the percentages of the elementsspecified in Section 7. If the secondary melting processes of 5.1 are employed, the heat analysis shall be obtained from oneremelted ingot or the
32、 product of one remelted ingot of each primary melt. The chemical composition thus determined, or thatdetermined from a product analysis made by the manufacturer, if the latter has not manufactured the steel, shall be reported to thepurchaser or the purchasers representative, and shall conform to th
33、e requirements specified in Section 7.9. Product Analysis9.1 At the request of the purchaser, analyses of two pipes from each lot (see 20.1) shall be made by the manufacturer from thefinished pipe. The results of these analyses shall be reported to the purchaser or the purchasers representative and
34、shall conformto the requirements specified in Section 7.9.2 If the analysis of one of the tests specified in 9.1 does not conform to the requirements specified in Section 7, analyses shallbe made on additional pipes of double the original number from the same lot, each of which shall conform to requ
35、irementsspecified.10. Tensile Requirements10.1 The material shall conform to the requirements as to tensile properties given in Table 2.11. Bending Requirements11.1 For pipe NPS 2 DN 50 and under, a sufficient length of pipe shall stand being bent cold through 90 around a cylindricalmandrel, the dia
36、meter of which is twelve times the outside diameter (as shown in ASME B 36.10M) of the pipe, withoutdeveloping cracks. When ordered for close coiling, the pipe shall stand being bent cold through 180 around a cylindrical mandrel,the diameter of which is eight times the outside diameter (as shown in
37、ASME B 36.10M) of the pipe, without failure.11.2 For pipe whose diameter exceeds 25 in. 635 mm and whose diameter to wall thickness ratio, where the diameter to wallthickness ratio is the specified outside diameter divided by the nominal wall thickness, is 7.0 or less, the bend test shall beconducte
38、d. The bend test specimens shall be bent at room temperature through 180 with the inside diameter of the bend being1 in. 25 mm without cracking on the outside portion of the bent portion.Example: For 28 in. 711 mm diameter 5.000 in. 127 mm thick pipe the diameter to wall thickness ratio = 28/5 = 5.6
39、 711/127= 5.6.12. Flattening Tests12.1 Although testing is not required, pipe shall be capable of meeting the flattening test requirements of SupplementaryRequirement S3, if tested.A106/A106M 13313. Hydrostatic Test13.1 Except as allowed by 13.2, 13.3, and 13.4, each length of pipe shall be subjecte
40、d to the hydrostatic test without leakagethrough the pipe wall.13.2 As an alternative to the hydrostatic test at the option of the manufacturer or where specified in the purchase order, it shallbe permissible for the full body of each pipe to be tested with a nondestructive electric test described i
41、n Section 14.13.3 Where specified in the purchase order, it shall be permissible for pipe to be furnished without the hydrostatic test andwithout the nondestructive electric test in Section 14; in this case, each length so furnished shall include the mandatory markingof the letters “NH.” It shall be
42、 permissible for pipe meeting the requirements of 13.1 or 13.2 to be furnished where pipe withouteither the hydrostatic or nondestructive electric test has been specified in the purchase order; in this case, such pipe need not bemarked with the letters “NH.” Pipe that has failed either the hydrostat
43、ic test of 13.1 or the nondestructive electric test of 13.2 shallnot be furnished as “NH” pipe.13.4 Where the hydrostatic test and the nondestructive electric test are omitted and the lengths marked with the letters “NH,”the certification, where required, shall clearly state “Not Hydrostatically Tes
44、ted,” and the letters “NH” shall be appended to theproduct specification number and material grade shown on the certification.14. Nondestructive Electric Test14.1 As an alternative to the hydrostatic test at the option of the manufacturer or where specified in the purchase order as analternative or
45、addition to the hydrostatic test, the full body of each pipe shall be tested with a nondestructive electric test inaccordance with Practice E213, E309, or E570. In such cases, the marking of each length of pipe so furnished shall include theletters “NDE.” It is the intent of this nondestructive elec
46、tric test to reject pipe with imperfections that produce test signals equalto or greater than that produced by the applicable calibration standard.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 0
