Number of Tests10.1 Two test specimens for the determination of weight ofcoating shall be taken, one from each end of one length ofgalvanized pipe, selected at random from each lot of 50
28、0lengths or fraction thereof of each size.10.1.1 For purposes of testing, a lot shall consist of not morethan 500 lengths of pipe of the same type, grade, size, andweight.10.1.2 For electric-resistance welded pipe, one tensile testshall be made on one length of pipe from each lot of 500lengths, or f
29、raction thereof, of each size. A length is defined asthe length as ordered, except that in the case of orders for cutlengths shorter than single random, the term lot shall apply tothe lengths as rolled, prior to cutting to the required shortlengths.10.1.3 For continuous-welded pipe, one tensile test
30、 shall bemade on one length of pipe from each lot of 25 tons, or fractionthereof, of pipe NPS 112 and smaller, and from each lot of 50tons, or fraction thereof, of pipe NPS 2 and larger.11. Retests11.1 If the weight of coating of any lot does not conform tothe requirements specified in Section 7, re
31、tests of two addi-tional pipes from the same lot shall be made, each of whichshall conform to the requirements specified.12. Standard Weights12.1 The standard weights with the corresponding wallthickness for pipe of various nominal outside diameters areprescribed in Table 1 and Table 2.NOTE 3A syste
32、m of standard pipe sizes has been approved by theAmerican National Standards Institute as B 36.10 that dispenses with thedouble-extra-strong weight and reclassifies the standard and extra-strongweights, substituting, therefore, schedules of wall thicknesses based onminimum pressure-stress ratios. Wa
33、ll thicknesses corresponding to mostof these now listed as standard weight and extra-strong are incorporated inSchedules 40 and 80, respectively, of B 36.10.13. Dimensions, Mass, and Permissible Variations13.1 WeightThe weight of the pipe covered by Table 1and Table 2 shall not vary by more than 610
34、 % from thatprescribed.NOTE 4The weight tolerance of 610 % is determined from theweights of the customary lifts of pipe as produced for shipment by themill, divided by the number of feet of pipe in the lift. On pipe sizes overNPS 4 where individual lengths may be weighed, the weight tolerance isappl
35、icable to the individual length.13.2 DiameterFor pipe NPS 112 and under, the outsidediameter at any point shall not vary more than164 in. 0.4 mmover nor more than132 in. 0.8 mm under the standardspecified. For pipe NPS 2 and over, the outside diameter shallnot vary more than 61 % from the standard s
36、pecified.13.3 ThicknessThe minimum wall thickness at any pointshall not be more than 12.5 % under the nominal wall thicknessspecified.14. Lengths14.1 Lengths of toprail may be of random lengths, forexample, 16 ft 4.9 m to 24 ft 7.3 m, unless otherwisespecified. Post lengths shall be as noted in the
37、purchase orderor producer plans and specifications with a tolerance of 61 in.25.4 mm.15. Workmanship, Finish, and Appearance15.1 The finished pipe shall be galvanized and reasonablystraight and free of defects. Any imperfection that is deeperthan 1212 % of the wall thickness or violates the minimumw
38、all shall be considered a defect. All burrs at the ends of thepipe shall be removed.15.2 The zinc coating shall be free of voids or excessiveroughness.15.3 End finish shall be plain end square cut.15.4 Posts and rails shall be one piece free of weldedsections.16. Inspection and Certification16.1 All
39、 tests and inspection shall be made at the place ofmanufacture prior to shipment, unless otherwise specified, andshall be so conducted as not to interfere unnecessarily with theoperation of the works.16.2 Responsibility for inspection, unless otherwise speci-fied in the contract or purchase order, r
40、ests upon the producer.This includes performance of all inspection and test require-ments specified herein. Except as otherwise specified in thecontract order, the producer may use their own or any othersuitable facilities for the performance of the inspection and testrequirements specified herein u
41、nless disapproved by the pur-chaser. The purchaser shall have the right to perform any of theinspections and tests set forth in this specification where suchinspections are deemed necessary to ensure that materialconforms to prescribed requirements.17. Rejection17.1 Each length of pipe received from
42、 the manufacturermay be inspected by the purchaser and, if it does not meet therequirements of this specification based on the inspection andtest method as outlined in this specification, the length may berejected and the manufacturer shall be notified. Disposition ofrejected pipe shall be a matter
43、of agreement between themanufacturer and the purchaser.17.1.1 Pipe found in fabrication or installation to be unsuit-able for the intended use, under the scope and requirements ofthis specification, may be set aside and the manufacturernotified. Such pipe shall be subject to mutual investigation ast
44、o the nature and severity of the deficiency and the forming orinstallation, or both, conditions involved. Disposition shall bea matter for agreement.18. Certification18.1 The producer or supplier shall, upon request, furnish tothe purchaser a certificate of inspection stating that the materialhas be
45、en sampled, tested, and inspected in accordance with thisspecification, and has been found to meet the requirements.19. Product Marking19.1 Except as allowed by 19.6 and 19.7, each length ofpipe shall be legibly marked in the following sequence byrolling, stamping, or stenciling to show:F108306319.1
46、.1 Manufacturers name or mark,19.1.2 Country of origin,19.1.3 Method of manufacture (electric-resistance weldedor furnace welded),19.1.4 Specification number (year of issue not required),andNOTE 5Pipe that complies with multiple compatible specificationsmay be marked with the appropriate designation
47、 for each specification.19.1.5 Size (NPS and weight class, schedule number, ornominal wall thickness; or specified outside diameter andnominal wall thickness).19.2 Unless another marking format is specified in thepurchase order, length shall be marked in feet and tenths of afoot, or metres to two de
48、cimal places, dependent upon the unitsto which the pipe was ordered. The location of such markingshall be at the option of the manufacturer.19.3 Heat number, lot number, run number, or a combina-tion thereof shall be marked at the option of the manufacturer,unless specific marking is specified in th
