NOTES:
(1) Any carbon steel material may be used to a minimum temperature of-29°C(-20°0 for Category D Fluid Service.
(2) X Grades of API 5L, and ASTM A381 materials, may be used in accordance with Curve B if normalized or quenched and tempered.
(3) The following materials may be used in accordance with Curve D if normalized:
(a) ASTM A516 plate, all grades
(b) ASTM A671 pipe made from A516 plate, all grades
(c) ASTM A672 pipe made from A516 plate, all grades
(4) A welding procedure for the manufacture of pipe or components shall include impact testing of welds and HAZ for any design
minimum temperature below-29°C(-20°0, except as provided in Table 323.2.2,A-3(b).
(5) Impact testing in accordance with para. 323.3 is required for any design minimum temperature below-48°C (-55°0, except as
permitted by Note (3) in Table 323.2.2.
(6) For blind flanges and blanks, T shall be of the flange thickness.
