The DS-1 team has created this Drillstring Toolbox Premium! It's an advance 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. - Recommended makeup torques for many popular proprietary connections.
