General Requirements4.1 Material furnished under this specification shall con-fo
26、rm to the applicable requirements of the current edition ofSpecification A1016/A1016M, unless otherwise providedherein.5. Manufacture5.1 The tubes shall be made by the seamless or weldedprocess.5.2 At the manufacturers option, tubing may be furnishedeither hot finished or cold finished.6. Heat Treat
27、ment6.1 All material shall be furnished in the solution heat-treated condition. Except as provided in 6.2, the heat-treatmentprocedure shall consist of heating the material to a minimumtemperature or temperature range as specified for the grade inTable 2, followed by quenching in water or rapidly co
28、oling byother means. Alternatively, for seamless tubes, immediatelyfollowing hot forming while the temperature of the tubes is notless than the specified minimum solution treatmenttemperature, tubes may be individually quenched in water orrapidly cooled by other means.6.2 Controlled structural or sp
29、ecial service characteristicsshall be specified as a guide for the most suitable heattreatment. If the final heat treatment is at a temperature under1900 F 1040 C and is so specified on the order, each tubeshall be stenciled with the final heat treatment temperature indegrees Fahrenheit degrees Cels
30、ius after the suffix “HT”.6.3 A solution annealing temperature above 1950 F 1065C may impair the resistance to intergranular corrosion aftersubsequent exposure to sensitizing conditions in TP321,TP347, and TP348. When specified by the purchaser, a lowertemperature stabilization or re-solution anneal
31、 shall be usedsubsequent to the initial high temperature solution anneal (seeSupplementary Requirement S3).7. Chemical Composition7.1 The steel shall conform to the requirements as tochemical composition as prescribed in Table 1.8. Product Analysis8.1 An analysis of either one billet or one length o
32、fflat-rolled stock or one tube shall be made from each heat. Thechemical composition thus determined shall conform to therequirements specified.8.2 A product analysis tolerance of Table number A1.1 inSpecification A480/A480M shall apply. The product analysistolerance is not applicable to the carbon
33、content for materialwith a specified maximum carbon of 0.04 % or less.8.3 If the original test for product analysis fails, retests oftwo additional billets, lengths of flat-rolled stock, or tubes shallbe made. Both retests for the elements in question shall meetthe requirements of the specification;
34、 otherwise all remainingmaterial in the heat or lot shall be rejected or, at the option ofthe producer, each billet, length of flat-rolled stock, or tubemay be individually tested for acceptance. Billets, lengths offlat-rolled stock, or tubes which do not meet the requirementsof the specification sh
35、all be rejected.9. Mechanical Tests Required9.1 Flaring Test (Seamless Tubes)One test shall be madeon specimens from one end of one tube from each lot offinished tubes.TABLE 2 Heat Treatment and Hardness RequirementsGrade UNS NumberAustenitizingTemperature, min orrange F CHardness, maxTP201 S20100 1

When final heat trea
42、tment is in a batch-typefurnace, a heat-treatment lot shall include only those tubes ofthe same size and from the same heat that are heat treated in thesame furnace charge. When the final heat treatment is in acontinuous furnace or when the heat-treated condition isobtained directly by quenching aft
43、er hot forming, the numberof tubes of the same size and from the same heat in aheat-treatment lot shall be determined from the size of thetubes as prescribed in Table 3.9.4 Hardness TestBrinell or Rockwell hardness determi-nation shall be made on specimens from two tubes from eachlot. The term lot a
44、pplies to all tubes prior to cutting, of the samenominal diameter and wall thickness that are produced fromthe same heat of steel. When final heat treatment is in abatch-type furnace, a lot shall include only those tubes of thesame size and the same heat which are heat treated in the samefurnace cha
45、rge. When the final heat treatment is in a continuousfurnace or when the heat-treated condition is obtained directlyby quenching after hot forming, a lot shall include all tubes ofthe same size and heat, heat treated in the same furnace at thesame temperature, time at heat, and furnace speed, or all
46、 tubesof the same size and heat, hot formed and quenched in the sameproduction run.9.5 When more than one heat is involved, the flaring,flanging, and hardness test requirements shall apply to eachheat.9.6 Reverse Flattening TestFor welded tubes, one reverseflattening test shall be made on a specimen
47、 from each 1500 ft460 m of finished tubing. Coiled tubing greater than 1500 ft450 m in length shall be sampled at both ends. A coil must becontinuous without any circumferential butt welds.10. Hydrostatic or Nondestructive Electric Test10.1 Each tube shall be subjected to the nondestructiveelectric
48、test or the hydrostatic test. The type of test to be usedshall be at the option of the manufacturer, unless otherwisespecified in the purchase order.11. Hardness Requirements11.1 Tubes shall have a hardness number not exceeding thevalues shown for the grade in Table 2.11.2 For tubing less than 0.065 in. 1.65 mm in wallthickness, it is permiss
