A

2、number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification2covers two grades of electric-resi

3、stance-welded steel pipe in NPS 2 to NPS 30 DN 50 to DN750 inclusive, with nominal (average) wall thickness up to0.500 in. 12.70 mm, inclusive, and in nominal sizes NPS34to NPS 5 DN 20 to DN 125 inclusive with nominal (average)wall thickness 0.083 in. 2.11 mm to 0.134 in. 3.40 mm,depending on size.

4、Pipe having other dimensions (Note 1) maybe furnished provided such pipe complies with all otherrequirements of this specification. The pipe is intended forconveying gas, vapor, water or other liquid; only Grade A isadapted for flanging and bending (Note 2). The suitability ofpipe for various purpos

5、es is somewhat dependent upon itsdimensions, properties, and conditions of service, so that thepurpose for which the pipe is intended should be stated in theorder. The pipe may be furnished either nonexpanded or coldexpanded at the option of the manufacturer. When pipe is coldexpanded, the amount of

6、 expansion shall not exceed 1.5 % ofthe outside diameter pipe size.NOTE 1A comprehensive listing of standardized pipe dimensions iscontained in ASME B36.10M.NOTE 2This provision is not intended to prohibit the cold bending ofGrade B pipe.1.2 The values stated in either SI units or inch-pound unitsar

29、er on samplesof pipe selected at random and shall conform to the require-ments specified in Table 2. Methods and Practices relating tochemical analysis shall be in accordance with Test Method,Practices, and Terminology A751.8. Mechanical Properties Requirements8.1 Tensile Properties:8.1.1 The materi

30、al shall conform to the requirements as totensile properties prescribed in Table 1.8.1.2 The yield strength shall be determined by the offsetmethod utilizing 0.2 % of the gage length or by the totalextension under load method using 0.5 % of the gage length.8.1.3 Longitudinal test specimens shall be

31、full-size longitu-dinal test specimens (see Figure A2.1 of Test Methods andDefinitions A370) or longitudinal strip test specimens (seeSpecimen No. 4 in Fig. A2.3 of Test Methods and DefinitionsA370).8.2 The test specimen taken across the weld shall show atensile strength not less than the minimum te

32、nsile strengthspecified for the grade of pipe ordered. This test will not berequired for pipe under NPS 8 DN 200.9. Flattening Test9.1 A specimen at least 4 in. 100 mm in length shall beflattened cold between parallel plates in three steps with theweld located either 0 or 90 from the line of directi

33、on of forceas required in 9.2. During the first step, which is a test forductility of the weld, no cracks or breaks on the inside oroutside surfaces shall occur before the distance between theplates is less than two thirds of the original outside diameter ofthe pipe. As a second step, the flattening

34、 shall be continued.During the second step, which is a test for ductility exclusiveof the weld, no cracks or breaks on the inside or outsidesurfaces shall occur before the distance between the plates isless than one third of the original outside diameter of the pipebut is not less than five times th

35、e wall thickness of the pipe.During the third step, which is a test for soundness, theflattening shall be continued until the specimen breaks or theopposite walls of the pipe meet. Evidence of laminated orunsound material or of incomplete weld that is revealed duringthe entire flattening test shall

36、be cause for rejection.9.2 For pipe produced in single lengths, the flattening testspecified in 9.1 shall be made on both crop ends cut from eachlength of pipe. The tests from each end shall be madealternately with the weld at 0 and at 90 from the line ofdirection of force. For pipe produced in mult

37、iple lengths, theflattening test shall be made on crop ends representing the frontand back of each coil with the weld at 90 from the line ofdirection of force, and on two intermediate rings representingeach coil with the weld 0 from the line of direction of force.9.3 Surface imperfections in the tes

38、t specimen before flat-tening, but revealed during the first step of the flattening test,shall be judged in accordance with the finish requirements inSection 13.9.4 Superficial cracks as a result of surface imperfectionsshall not be cause for rejection.10. Hydrostatic Test10.1 Except as provided for

39、 in 10.3, each length of pipeshall be hydrostatically tested at the mill, without leakagethrough the wall, to a pressure calculated from the followingequation:P 5 2St/Dwhere:P = minimum hydrostatic test pressure, psi, kPa. The testpressure need not exceed 2500 psi 1700 kPa,S = allowable fiber stress

40、 18 000 psi 124 000 kPa forGrade A and 21 000 psi 144 000 kPa for Grade B.This does not prohibit testing at higher pressure at themanufacturers option,t = specified wall thickness, in. mm, andD = specified outside diameter, in. mm.Plain end pipe may be tested at the discretion of themanufacturer in

41、single lengths or in multiple lengths.10.2 The hydrostatic pressure shall be maintained for notless than 5 s.10.3 When specified in the order, pipe may be furnishedwithout hydrostatic testing, and each length so furnished shallinclude with the mandatory marking the letters “NH.”NOTE 3This provision

42、is not intended to apply to light wall (Schedule10) pipe listed in Table X1.1.10.4 When certification is required by the purchaser and thehydrostatic test has been omitted, the certification shall clearlystate “Not Hydrostatically Tested.” The specification numberand material grade, as shown on the

43、certification, shall befollowed by the letters “NH.”11. Nondestructive Examination Requirements11.1 As an alternate to the hydrostatic test, and whenaccepted by the purchaser, each pipe shall be tested with anondestructive electric test. Except for pipe produced on ahot-stretch reducing mill, the we

44、ld seam of each length of pipeshall be tested with a nondestructive test in accordance withPractices E213, E273, E309,orE570. Each length of pipeproduced on a hot-stretch-reducing mill shall be tested with anondestructive electric test that inspects the full volume of thepipe in accordance with Prac

45、tices E213, E309,orE570.11.2 Recognized methods for meeting this test are electro-magnetic (eddy current) or ultrasonic.11.3 The following information is for the benefit of the userof this specification:11.3.1 The ultrasonic examination referred to in this speci-fication is intended to detect longit

47、orientedimperfections of short, deep imperfections.11.3.2 The eddy-current examination referenced in thisspecification has the capability of detecting significant imper-fections, especially of the short, abrupt type.11.3.3 The hydrostatic test referred to in Section 10 is a testmethod provided for i

48、n many product specifications. This testhas the capability of finding imperfections of a size permittingthe test fluid to leak through the tube wall and may be eithervisually seen or detected by a loss of pressure. This test maynot detect very tight, through-the-wall imperfections or imper-fections

49、that extend an appreciable distance into the wallwithout complete penetration.11.3.4 A purchaser interested in ascertaining the nature(type, size, location, and orientation) of imperfections that canbe detected in the specific application of these examinationsshould discuss this with the manufacturer of the tubularproduct.11.4 In order to accommodate the various types of nonde-structive electric testing equipment and techniques in use, thecalibration pipe shall contain, at the option of the producer,
