continuous furnace or when the heat-treated condition is obtained directly by quenching after hot forming, the number of tubes of the same size and from the same heat in a heat-treatment lot shall be determined from the size of the tubes as prescribed in Table 2.

注2：这项适用于切割前同一炉钢生产的同一公称尺寸和壁厚的所有管子。当最终热处理是在周期式炉中进行的，一批包括同一尺寸，同一炉号是在相同热处理炉内装料下进行热处理的那些管子。当最终热处理在连续炉中进行时，一批中同一炉号和同一尺寸的管于根数应按表2中的规定确定。

9.2 Flange Test (Welded Tubes)—One test shall be made on specimens from one end of one tube from each lot (Note 2) of finished tubes.

9.2 卷边试验（焊接钢管），其测试应从每批（注2）一支成品管的端部取一个试样。

9.3 Hardness Test—Brinell or Rockwell hardness determination shall be made on specimens from two tubes from each lot. The term lot applies to all tubes prior to cutting, of the same nominal diameter and wall thickness that are produced from the same heat of steel. When final heat treatment is in a batch-type furnace, a lot shall include only those tubes of the same size and the same heat which are heat treated in the same furnace charge. When the final heat treatment is in a continuous furnace or when the heat-treated condition is obtained directly by quenching after hot forming, a lot shall include all tubes of the same size and heat, heat treated in the same furnace at the same temperature, time at heat, and furnace speed, or all tubes of the same size and heat, hot formed and quenched in the same production run.

9.3 硬度试验布氏或洛氏硬度测定应在从每批成品管取两个试样。这项适用于切割前同一炉钢生产的同一公称尺寸和壁厚的所有管于。当最终热处理是在周期式炉中进行的，一批包括同一尺寸，同一炉号是在相同热处理炉内装料下进行热处理的那些管子。当最终热处理是在连续炉中进行时，一批应包括同一尺寸、同一炉号及在相同热处理炉内以相同温度、相同加热时间及炉速作热处理的所有管子。

TABLE 2 Number of Tubes in a Lot Heat Treated by the Continuous Process or by Direct Quench After Hot Forming

表2：通过连续热处理或固溶处理的批量钢管支数 Size of Tube 钢管尺寸 Size of Lot批量 2 in. and over in outside diameter

and 0.200 in.(5.08 mm) and over in wall thickness tubes 外径≥2英寸（50.8㎜）和壁厚≥0.200不超过50根钢管 英寸（5.08㎜）

Less than 2 in. but over 1 in. in outside diameter or over 1 in. in

outside diameter and under 0.200 in. (5.08 mm) in wall thickness tubes

外径＞1英寸（25.4㎜），＜2英寸不超过75根钢管 （50.8㎜），壁厚＜0.200英寸（5.08㎜）

tubes 外径≤1英寸（25.4㎜）

不超过125根钢管

9.4 When more than one heat is involved, the flaring,flanging, and hardness test requirements shall apply to each heat. 9.4 当包含一个以上的炉号时，扩口、卷边和硬度测试要求每个炉号进行试验。

9.5 Reverse Flattening Test—For welded tubes, one reverse flattening test shall be made on a specimen from each 1500 ft (460 m) of finished tubing. Coiled tubing greater than 1500 ft (450 m) in

length shall be sampled at both ends. A coil must be continuous without any circumferential butt welds. 9.5 反向压扁试验—对于焊接管，扭转压扁试验应从每1500英尺（460米）的成品管取一个试样。螺旋焊管大于1500英尺（450米）的长度应在两端取样，螺旋焊必须连续无任何环对接焊缝。

10. Hydrostatic or Nondestructive Electric Test

水压或涡流检测

10.1 Each tube shall be subjected to the nondestructive electric test or the hydrostatic test. The type of test to be used shall be at the option of the manufacturer, unless otherwise specified in the purchase order.

10.1 每根钢管必须经无损电测（涡流）试验或水压试验。测试类型由制造商选择，除非采购订购单另有指定。

11. Hardness Requirements 硬度要求

11.1 Grades TPXM-29, S34565, N08367, and N08926 tubes shall have a hardness number not exceeding 256 HB/270 HV or 100 HRB. Grades TPXM-10, TPXM-11, and TPXM-19 tubes shall have a hardness number not exceeding 269 HB/285 HV or 25 HRC. S20100 and S31254 shall have a hardness number not exceeding 220 HB/230 HV or 96 HRB. S20153 and S32654 shall have a hardness number not exceeding 250 HB/263 HV or 100 HRB. Tubes made from all other grades shall have a hardness number not exceeding 192 HB/200 HV or 90 HRB. 11.1 TPXM - 29，S34565，N08367和N08926钢种的钢管硬度不超过256 HB/270HV或100HRB。TPXM-10，TPXM-11，和TPXM–19钢种的钢管硬度不超过269 HB/285HV或25HRC。 S20100和S31254的硬度不超过220 HB/230HV或96HRB。 S20153和S32654的硬度不超过250 HB/263HV或100HRB。所有其他钢种的硬度不超过192 HB/200HV或90HRB。

11.2 For tubing less than 0.065 in. (1.65 mm) in wall thickness, it is permissible to use the Rockwell superficial hardness test or the Vickers hardness test. When the Vickers test is used, the values of 11.1 will apply. The superficial hardness number for Grade TPXM-29 and S20153 tubes shall not exceed 80 on the 30 T scale or 92 on the 15 T scale. The hardness number for Grades TPXM-10, TPXM-11, and TPXM-19 tubes shall not exceed 46 on the 30 N scale or 73 on the 15 N scale. The hardness number for S20100 and S31254 shall not exceed 79 on the 30 T scale or 91 on the 15 T scale.
