The values stated in eachsystem are not exact equivalents; therefore, each system mustbe used independently of the

Chemical Composition5.1 Chemical AnalysisSamples for chemical analysis andmethod of analysis shall be in accordance with Test Methods,Practices, and Terminology A 751.5
23、.2 Heat AnalysisIf the heat analysis reported by the steelproducer is not sufficiently complete for conformance with theheat analysis requirements of the applicable product specifica-tion to be fully assessed, the manufacturer may complete theassessment of conformance with such heat analysis require
24、-ments by using a product analysis for the specified elementsthat were not reported by the steel producer, provided thatproduct analysis tolerances are not applied and the heatanalysis is not altered.5.2.1 For stainless steels ordered under product specifica-tions referencing this specification of g
25、eneral requirements, thesteel shall not contain an unspecified element, other thannitrogen, for the ordered grade to the extent that the steelconforms to the requirements of another grade for which thatelement is a specified element having a required minimumcontent. For this requirement, a grade is
26、defined as an alloydescribed individually and identified by its own UNS designa-tion in a table of chemical requirements within any specifica-tion listed within the scope as being covered by this specifi-cation.5.3 Product AnalysisProduct analysis requirements andoptions, if any, are contained in th
27、e product specification.6. Mechanical Requirements6.1 Method of Mechanical TestsThe specimens and themechanical tests required shall be in accordance with TestMethods and Definitions A 370, especially Annex A2 thereof.6.2 Specimens shall be tested at room temperature.6.3 Small or subsize specimens a
28、s described in Test Meth-ods and Definitions A 370 may be used only when there isinsufficient material to prepare one of the standard specimens.When using small or subsize specimens, the largest onepossible shall be used.7. Tensile Requirements7.1 The material shall conform to the requirements as to
29、tensile properties prescribed in the individual specifications.7.2 The yield strength corresponding to a permanent offsetof 0.2 % of the gage length or to a total extension of 0.5 % ofthe gage length under load shall be determined.7.3 If the percentage of elongation of any test specimen isless than
30、that specified and any part of the fracture is more than34 in. 19.0 mm from the center of the gage length, asindicated by scribe marks on the specimen before testing, aretest shall be allowed.8. Permissible Variation in Weight8.1 The weight of any length of pipe NPS 12 and under shallnot vary more t
31、han 10 % over or 3.5 % under that specified.For sizes over NPS 12, the weight of any length of pipe shallnot vary more than 10 % over or 5 % under that specified.Unless otherwise specified, pipe of NPS 4 and smaller may beweighed in convenient lots; pipe in sizes larger than NPS 4shall be weighed se
32、parately.9. Permissible Variations in Wall Thickness9.1 Seamless and Welded (no filler metal added)Theminimum wall thickness at any point shall be within thetolerances specified in Table 1 , except that for welded pipe theweld area shall not be limited by the over tolerance. Theminimum wall thicknes
33、s on inspection for 12.5 % is shownin Table X1.1.9.2 Forged and BoredThe wall thickness shall not varyover that specified by more than18 in. 3.2 mm.

35、. Permissible Variations in Inside Diameter10.1 Forged and Bored, and CastThe inside diametershall not vary under that specified by more than116 in. 1.6mm. There shall be no variation over the specified insidediameter.11. Permissible Variations in Outside Diameter11.1 Variations in outside diameter,
36、 unless otherwise speci-fied, shall not exceed the limits prescribed in Table 2. Thetolerances on outside diameter include ovality except asprovided for in 11.211.2 Thin-wall pipe usually develops significant ovality(out-of-roundness) during final annealing, straightening, orboth. The diameter toler
37、ances of Table 2 are not sufficient toprovide for additional ovality expected in thin-wall pipe andare applicable only to the mean of the extreme (maximum andminimum) outside diameter readings in any one cross-section.However, for thin-wall pipe the difference in extreme outsidediameter readings (ov
38、ality) in any one cross-section shall notexceed 1.5 % of the specified outside diameter.12. Permissible Variations in Length12.1 Seamless and Welded (no filler metal added)If defi-nite cut lengths are ordered, no length of pipe shall be under thelength specified and not more than14 in. 6 mm over tha
39、tspecified.12.2 Forged and Bored, Cast, and Cast Cold-WroughtIfdefinite cut lengths are ordered, no length of pipe shall beunder the length specified and not more than18 in. 3 mm overthat specified.12.3 For pipe ordered to random lengths, the lengths andvariations shall be agreed upon between the ma
40、nufacturer andpurchaser.12.4 No jointers are permitted unless otherwise agreedupon.13. Standard Weight13.1 A system of standard pipe sizes has been approved bythe American National Standards Institute as ANSI B 36.10and B 36.19. These standard sizes do not prohibit the produc-tion and use of other s
41、izes of pipe produced to the variousspecifications referenced to this Specification.13.2 For nonstandard sizes of pipe, the calculated weightper foot, shall be determined from the following equation:W 5 CD 2 t!t (1)where:C = 10.69 0.0246615,W = weight, lb/ft kg/m,D = specified or calculated (from sp
42、ecified inside diameterand wall thickness) outside diameter, in. mm, andt = specified wall thickness, in. (to 3 decimal places) mmto 2 decimal places.NOTE 2The weights given in the American National Standards andthe calculated weights given by Eq 1 are based on the weights for carbonsteel pipe. The
43、weight of pipe made of ferritic stainless steels may beabout 5 % less, and that made of austenitic stainless steel about 2 %greater than the values given.14. Ends14.1 Unless otherwise specified, the pipe shall be furnishedwith plain ends. All burrs at the ends of the pipe shall beremoved.15. Straigh
44、tness15.1 The finished pipe shall be reasonably straight.15.2 For metal-arc welded pipe, the maximum deviationfrom a 10-ft 3.0-m straightedge placed so that both ends arein contact with the pipe shall be18 in. 3.2 mm. For metal-arcwelded pipe with lengths shorter than 10 ft 3.0 m, thismaximum deviat
45、ion shall be pro-rated with respect to the ratioof the actual length to 10 ft 3.0 m.16. Repair by Welding16.1 Repair by welding of defects in seamless pipe (includ-ing centrifugally cast and forged and bored) and of platedefects in welded pipe and, when specifically stated by theproduct specificatio
46、n weld seam defects in welded pipe, shallbe permitted subject to the approval of the purchaser and withthe further understanding that the composition of the depositedfiller metal shall be suitable for the composition being welded.Defects shall be thoroughly chipped or ground out beforewelding and ea
47、ch repaired length shall be reheat treated orstress relieved as required by the applicable specification. Eachlength of repaired pipe shall be tested hydrostatically asrequired by the product specification.16.2 Repair welding shall be performed using proceduresand welders or welding operators that h
