BTC-compatible design providing more torque and improved performance widely used in Shale applications and for drilling with casing

DWC/C is a very cost competitive product providing higher performance than API-BTC threads, thanks to its optimized thread profile and pin-to-pin shoulder (or coupling shoulder option).
It provides higher compression, bending resistance and higher torque capacity than BTC, making it the perfect solution for onshore applications such as shale plays and geothermal wells, and for drilling with casing challenges.
DWC/C is available with many options to meet operator challenges: higher torque design, internal shoulder coupling, seal ring feature, optimal coupling OD size, and more.
