Given new 2.5 inch 6X19 Extra Improved Plow Steel wire rope, what is the maximum tension that can be applied to the fast line while remaining below the API recommended design factor: for a) stuck pipe, b) hoisting, or c) casing, respectively?
This can be quickly solved without leaving 1 RIG 5. What I like about this break strength table is that I combine data from multiple sources most likely needed in real life, and merely ignore the rest. Remember, you can always interpolate for a quick, rough check on the rarer sizes, and this table meets this need.
The break strength is shown to be 604M lbf. Next, see the note: Design Factor API recommends a minimum 3 for hoisting, 2 for casing or stuck pipe, respectively. So: 604M/2, 604M/3, 604M/2, or (A).
