Drillstring Toolbox Premium

The same lovable engineers behind the DS-1 standard have created this Drillstring Toolbox Premium! It's an advanced calculator that does everything the free Drillstring Toolbox does and more! With it you can find:

- API-recommended makeup torques for drill-stem connections with whatever sizes you want to plug in.

- The "T4" (maximum tensile capacity) torque for those connections, too.

- Adjusted makeup torques when you want to optimize away from the standard numbers.

- Tensile and torsion capacities for standard, thick-walled, and custom drill pipe tubes.

- A combined load curve for whatever combination you come up with, which you can email to your colleagues.
