See Pipe Tables @ cell I5 for tubular data... Review the User Notes starting @ cell

If the Max Pull Calculation exceeds 80% of the Tensile Rating for the pipe that extends to the surface, then and only then will 80% ofthis pipe's Tensile Rating plus the weight of the Traveling Equipment be considered the MAX PULL FOR THIS STRING. If the pipein use is classified as 'Used API Premium Class', a Tensile Safety Factor of 1.0 is acceptable.
