Materials and Manufacture5.1 The pipe shall be made by the electric-fusion (arc)welded process. All seams of welded pipe shall be butt jointsand girth, longitudinal, or helical orientatio
17、n made usingcomplete joint penetration welds.5.2 The longitudinal edges of the steel shall be shaped togive the most satisfactory results by the particular weldingprocess employed. The weld shall be of reasonably uniformwidth and height for the entire length of the pipe.5.3 The steel from which the

For purposes of testing,marking, and certification when required, the requi
19、rements forthe pipe grade of material shall be established by the Specifi-cation A1097 steel specification designation and grade, whenapplicable.6. Qualification of Welding and Welding Procedures6.1 Welding operators and procedures shall be qualified inaccordance with the AWS D1.1/D1.1M or other wel
20、ding codeacceptable by the purchaser.7. Weights Per Unit Length7.1 For pipe the weight per unit length shall be calculated asfollows:W 5 10.69D 2 t!t (1)where:W = weight per unit length, lb/ft,D = specified outside diameter, in., andt = specified nominal wall thickness, in.8. Permissible Variations
21、in Weights and Dimensions8.1 WeightEach length of pipe weight when measuredshall not vary more than 5 % under its theoretical weight,calculated using its length and its weight per unit length (seeSection 7).8.2 Outside DiameterThe outside diameter of casing pipemeasured circumferentially shall not v
22、ary more than the lesserof 61 % from the specified outside diameter, or 634 in. (19mm) in circumference.8.3 RoundnessThe pipe diameter as measured along anysingle plane shall not vary more than 1 % from the specifieddiameter.8.4 StraightnessThe maximum deviation from a straightline, over the entire
23、pipe length, shall be 0.1 % of the pipelength.8.5 ThicknessThe pipe wall thickness when inspectedshall not be less than 87.5 % of the nominal thickness at anylocation. Pipe wall thickness shall not be in excess of 112.5 %of the nominal thickness unless approved by the purchaser.Thickness requirement
24、s are independent of the weight require-ments of 8.1.NOTE 1The minimum permissible wall thickness on inspection isshown in Table X1.1 (see Appendix X1) for various nominal wallthicknesses.9. Lengths9.1 The lengths shall be as specified on the order with atolerance of 612 in. (13 mm), except that the
25、 shorter lengthsfrom which test coupons have been cut may also be shipped.10. Ends10.1 Casing pipe shall be furnished with interlocking jointends, beveled ends, or plain ends. The pipe end shall not varyby more than 618 in. (3 mm) from a plane perpendicular to thepipe axis.10.2 Casing pipe specified
26、 with plain ends shall have eitherflame-cut or machine-cut ends, with the burrs at the endsremoved.10.3 For ends specified to be beveled, the bevel angle shallbe 30 +5, -0, measured from a line drawn perpendicular tothe axis of the pipe.10.4 For ends specified with interlocking joints, the jointshal
27、l be machined either directly on the pipe end or on a ringthat is butt welded to the end of the pipe section.Attached ringsmay be thicker than the pipe wall and may be made from anysteel compliant with 5.3.11. Number of Tests11.1 One reduced-section weld tension test shall be made,representing each
28、lot of 1000 ft (300 m) of pipe or fractionthereof of each diameter and thickness.11.2 It shall be permissible to discard any test specimen thatshows defective machining or develops imperfections andsubstitute another test specimen from the same lot.12. Retests12.1 If the results of the tension test
29、representing any lot failto conform to the applicable requirements, the lot shall berejected or retested using two additional lengths from the lot,with each such test being required to conform to such specifiedrequirements.13. Test Specimens and Test Methods13.1 The weld-test specimens for the reduc
30、ed-section ten-sion test shall be taken perpendicularly across the weld andfrom the end of the pipe or, alternatively, from flat test piecesof material conforming to the requirements in the specificationsused in the manufacture of the pipe. The alternative weld-testspecimens shall be welded with the
31、 same procedure and by thesame operator and equipment, and in sequence with thewelding of the longitudinal joints in the pipe. The test piecesshall have the weld approximately in the middle of thespecimen.A1097 16213.2 Reduced-section tension test specimens shall be pre-pared in accordance with Fig.
32、 21 of Test Methods andDefinitions A370.13.3 Reduced-section tension test specimens, taken perpen-dicularly across the weld with the weld shall show a tensilestrength not less than 95 % of the specified minimum strengthof the grade of steel.At the manufacturers option, the test maybe made without re
33、moving the weld reinforcement, or withalternative weld test specimens as defined in 13.1, in whichcase the tensile strength shall be not less than the specifiedminimum tensile strength for the grade of steel used.13.4 Specimens shall be tested at room temperature.14. Workmanship, Finish, and Appeara
34、nce14.1 The finished pipe shall not contain imperfections insuch number or of such character as to render the pipeunsuitable for casing pipe.14.2 Surface imperfections having a depth not in excess of25 % of the specified nominal wall thickness shall be accept-able. It shall be permissible to establi
35、sh the depth of suchimperfections by grinding or filing.14.3 Surface imperfections having a depth in excess of 25 %of the specified nominal wall thickness shall be considered tobe defects. It shall be permissible for defects not deeper than3313 % of the specified nominal wall thickness to be repaire
36、dby welding, provided that the defect is completely removedprior to welding.15. Inspection15.1 The inspector representing the purchaser shall haveentry, at all times while work on the contract of the purchaseris being performed, to all parts of the manufacturers worksthat concern the manufacture of
37、the material ordered. Themanufacturer shall afford the inspector all reasonable facilitiesto satisfy the inspector that the material is being furnished inaccordance with the requirements of this specification and anyother requirements specified in the purchase order.All tests andinspections shall be

39、ot meet the requirementsof this specification, based upon the applicable inspection andtest methods of the standard. The purchaser shall notify themanufacturer of any pipe that has been rejected, and thedisposition of such pipe shall be subject to agreement betweenthe manufacturer and the purchaser.
40、16.2 Pipe found in fabrication or installation to be unsuit-able for the intended end use within the scope of thisspecification, based on the requirements of this specificationshall be set aside. The purchaser shall notify the manufacturerof any pipe that has been set aside. Such pipe shall be subje
41、ctto mutual investigation as to the nature and severity of thedeficiency and conditions involved. The disposition of suchpipe shall be subject to agreement between the manufacturerand the purchaser.17. Certification17.1 Where specified in the purchase order, the manufac-turer shall furnish a certifi
42、cate of compliance stating that thecasing pipe was manufactured, tested, and inspected in accor-dance with the requirements of this specification (includingyear date) and any requirements specified in the purchaseorder, and was found to meet such requirements.17.2 Where specified in the purchase ord
43、er, the manufac-turer shall furnish a test report containing the results of theapplicable heat analyses, product analyses, and tension tests asdefined in theASTM standard for steel used in the manufactureof the pipe.18. Product Marking18.1 Each length of casing pipe shall be legibly marked bystencil
44、ing, stamping, or rolling to show: the name or brand ofthe manufacturer, the outside diameter, nominal wall thickness,length, the specification designation (year date not required),and the specified minimum yield strength.18.2 Bar CodingIn addition to the requirements in 18.1,itshall be permissible
45、for bar coding to be used as a supplemen-tary identification method.19.
