Mechanical Tests Required8.1 Tension TestOne transverse tension test of the weldshall be made on each lot (Note 2) of finished
44、 pipe.NOTE 2The term “lot” applies to each 200 ft 60 m or less of pipe ofthe same NPS and wall thickness (or schedule number) which is producedfrom the same heat of steel and subjected to the same finishing treatmentin a continuous furnace. When final heat treatment is in a batch-typefurnace, the lo
45、t shall include only that pipe which is heat treated in thesame furnace charge. When no heat treatment is performed following finalforming operations, the lot shall include each 200 ft 60 m or less of pipeof the same NPS and wall thickness (or schedule number) which isproduced from the same heat of
46、steel.8.2 Transverse Guided-Bend Weld TestOne test (twospecimens) of the weld shall be made on each lot (Note 2)offinished pipe.8.3 Pressure or Nondestructive Electric TestEach lengthof pipe shall be subjected to a pressure test or a nondestructiveelectric test as prescribed in Section 5.9. Permissi
47、ble Variations in Wall Thickness9.1 The minimum wall thickness at any point shall not bemore than 0.018 in. 0.46 mm under the specified wallthickness. (This tolerance is slightly more than commercialtolerances on sheet and plate to allow for possible loss ofthickness caused by manufacturing operatio

Wherethe specified wall thickness is 0.188 in. 4.8 mm and heavier,the actual outside diameter, based on circumferentialmeasurement, may vary a maximum of 60.40 % from thespecified outside diameter. (Outside diameter tolerances closerthan shown above may be obtained by agreement between thepipe manufacturer and purchaser.)10.1.2 Out-of-RoundnessThe difference be
