Utilities
Free · Designed for iPad. Not verified for macOS.
Drillstring Toolbox is a free calculator from Standard DS-1 that gives you the drill-stem load capacities you need! You can choose an API connection (along with the size you're interested in) to find its recommended makeup torque and tensile capacity. Tap the "Tube" tab to find the tensile and torsion capacities for drill pipe tubes as well!
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
A few small updates: we've added non-preferred connections (those weird ones that API Spec 7-2 knows exist but doesn't want to encourage), and we've updated our contact information a bit.
