6.2.6 Fracture Toughness Tests 6.2.6.1 Charpy Impact Tests for PSL 1 For PSL 1 pipe, Charpy impact testing is not required. 6.2.6.2 Charpy Impact Tests for PSL 2 For pipe sizes and specified wall thicknesses as given in Table 14 (pipe in size and drop-weight test and wall thickness combinations not covered by this table are not required to be tested), the manufacturer shall conduct Charpy V-notch tests that meet the following requirements. (Refer to 9.8.4 for guidance pertaining to subsize specimens.) a. The test temperature shall be +32°F (0°C); however, pipe tested at a lower temperature is also acceptable if it meets all other applicable fracture toughness requirements below. b. For all grades, the required minimum average (set of three specimens) absorbed energy for each heat based on full size specimens shall be 20 ft-lb (27 J) for transverse specimens or 30 ft-lb (41 J) for longitudinal specimens, whichever is appli- cable per Table 14. c. For X80 only, the required minimum all-heat average absorbed energy for the entire order item, based on full size Charpy specimens shall be 50 ft-lb (68 J) for transverse spec- imens; or 75 ft-lb (101 J) for longitudinal specimens, whichever is applicable per Table 14. If the all-heat average of the order does not meet the applicable requirement, the manufacturer shall be responsible for the replacement of heats to bring the average up to the required level. d. For X80 only, the required minimum shear area shall be either 40% for each heat and 70% for the all-heat average of the order based on the Charpy test, or 40% for each heat and 60% for the all-heat average based on the drop-weight tear test. The drop-weight tear test option only applies for welded pipe in sizes 20 or larger. If the all-heat average of the order does not meet the required percentage of shear area, the man- ufacturer shall be responsible for the replacement of heats as necessary to bring the average up to the required level.
7 Dimensions, Weights, Lengths, Defects, and End Finishes 7.1 SPECIFIED DIMENSIONS Line pipe shall be furnished in the outside diameters and wall thicknesses specified on the purchase order; such dimen- sions shall be in accordance with one of the following: a. As given in Table 4, 5, 6A, 6B, 6C, E-6A, E-6B, or E-6C, whichever is applicable. b. By agreement between the purchaser and the manufac- turer, intermediate to the values given in Table 6A, 6B, 6C, E-6A, E-6B, or E-6C, whichever is applicable. 7.2 DIAMETER The outside diameter shall be within the tolerances speci- fied in Tables 7 and 8. For threaded pipe, the outside diameter at the threaded ends shall be such that the thread length, L 4 , and the number of full-crest threads in that length are within the applicable dimensions and tolerances specified in API Standard 5B. Pipe of sizes 20 and smaller shall permit the passage over the ends, for a distance of 4 in. (101.6 mm), of a ring gage that has a bore diameter not larger than the pipe’s specified outside diameter plus the applicable plus tolerance shown in Table 8. For submerged-arc welded pipe, ring gages may be slotted or notched to permit passage of the gage over the weld reinforcement. Ring gage measurements shall be made at least once per 4 hours per operating shift. Diameter measurements of pipe larger than size 20 shall be made with a diameter tape. Diameter measurements of pipe sizes 20 and smaller shall be made with a snap gage, caliper, or other device that measures actual diameter across a single plane, except that the manufacturer shall have the option of using a diameter tape. Diameter measurements shall be made at least once per 4 hours per operating shift.
