Note: All data based on nominal dimensions and calculated per standard methods unless otherwise noted.
Pipe properties based on pipe body dimensions (non-upset area).
Internal Pressure calculated per API Bulletin 5C3 which includes a 12.5% knockdown.
Collapse calculated per Murphey, C. E., and Langner, C.G., “Ultimate Pipe Strength Under Bending, Collapseand Fatigue”, ASME, Proceeding 4th International Offshore Mechanics and Arctic Engineering Symposium,Dallas, February 1985. All data nominal and calculated per standard methods. Alcoa does not assumeresponsibility for results obtained through the use of this information.
