Numbe
28、r 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 500lengths or fraction thereof of each size.10.1.1 For purposes of testing, a lot shall consist of not morethan 500 lengt
29、hs 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 fraction thereof, of each size. A length is defined asthe length as ordered, except that in the case of orders for cutle
30、ngths 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 shall bemade on one length of pipe from each lot of 25 tons, or fractionthereof, of pipe NPS 112 and smaller, and from
31、 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, retests of two addi-tional pipes from the same lot shall be made, each of whichshall conform to the requirements specifie
32、d.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 system of standard pipe sizes has been approved by ANSIas B 36.10 that dispenses with the double-extra-strong weight andrecl
33、assifies the standard and extra-strong weights, substituting, therefore,schedules of wall thicknesses based on minimum pressure-stress ratios.Wall thicknesses corresponding to most of these now listed as standardweight and extra-strong are incorporated in Schedules 40 and 80,respectively, of B 36.10
34、.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 % from thatprescribed.NOTE 4The weight tolerance of 610 % is determined from theweights of the customary lifts of pipe as produced for shipment by themill,
35、 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 isapplicable 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 mor
36、e 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 specified.13.3 ThicknessThe minimum wall thickness at any pointshall not be more than 12.5 % under the nominal wall thicknessspecified.14. Lengths14.1 Length
37、s 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 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
38、galvanized and reasonablystraight and free of defects. Any imperfection that is deeperthan 1212 % of the wall thickness or violates the minimumwall 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
39、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 tests and inspection shall be made at the place ofmanufacture prior to shipment, unless otherwise specified, andshall be so conducted as not to interfere u
40、nnecessarily with theoperation of the works.16.2 Responsibility for inspection, unless otherwise speci-fied in the contract or purchase order, rests upon the producer.This includes performance of all inspection and test require-ments specified herein. Except as otherwise specified in thecontract ord
41、er, the producer may use their own or any othersuitable facilities for the performance of the inspection and testrequirements specified herein unless disapproved by the pur-chaser. The purchaser shall have the right to perform any of theinspections and tests set forth in this specification where suc
42、hinspections are deemed necessary to ensure that materialconforms to prescribed requirements.17. Rejection17.1 Each length of pipe received from the manufacturermay be inspected by the purchaser and, if it does not meet therequirements of this specification based on the inspection andtest method as
43、outlined in this specification, the length may berejected and the manufacturer shall be notified. Disposition ofrejected pipe shall be a matter 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 sc
44、ope and requirements ofthis specification, may be set aside and the manufacturernotified. Such pipe shall be subject to mutual investigation asto the nature and severity of the deficiency and the forming orinstallation, or both, conditions involved. Disposition shall bea matter for agreement.18. Cer
45、tification18.1 The producer or supplier shall, upon request, furnish tothe purchaser a certificate of inspection stating that the materialhas been sampled, tested, and inspected in accordance with thisspecification, and has been found to meet the requirements.F108308319. Product Marking19.1 Except a
