S = Yield strength in pounds per square inch (kPa) determined in accordance with § 192.107. D = Nominal outside diameter of the pipe in inches (millimeters). T = Nominal wall thickness of the pipe in inches (millimeters). If this is unknown, it is determined in accordance with § 192.109. Additional wall thickness required for concurrent external loads in accordance with § 192.103 may not be included in computing design pressure. F = Design factor determined in accordance with § 192.111. E = Longitudinal joint factor determined in accordance with § 192.113. T = Temperature derating factor determined in accordance with § 192.115. (b) If steel pipe that has been subjected to cold expansion to meet the SMYS is subsequently heated, other than by welding or stress relieving as a part of welding, the design pressure is limited to 75 percent of the pressure determined under paragraph (a) of this section if the temperature of the pipe exceeds 900°F (482°C) at any time or is held above 600°F (316°C) for more than 1 hour.","truncated":false,"body_characters":1219}
