User-friendly Tool Joint - The XT is a conventional shoulder and thread connection. The XT spins up freely until shouldered, then is bucked up to the make-up torque. Make-up, running and break-out speeds of XT are similar to API connections.
High Torsional Limit - The XT connection offers significantly higher torsional capacity than standard API and NOV Grant Prideco's HI TORQUE® connections. This additional strength provides the required torque for the most extreme drilling applications.
Slim Profile - The XT's increased torsional strength allows for the use of a streamlined tool joint that is suitable for the pipe's torsional strength. XT connections can be configured with a smaller OD and larger ID compared to standard API connections without sacrificing torsional capacity. This allows a larger diameter drill pipe to be used for improved hydraulic performance.
True Flush Inside Diameter - There is no gap or change in the inside diameter from the box to the pin, creating a smoother flow with less turbulence. This also eliminates the recess in other connections where cement and solids can be trapped.
Rugged Durability - The robust XT design incorporates more steel in the critical areas of the connection resulting in less refacing and fewer recuts. In addition, because of the increased torional capacity, the XT connection greatly extends the life of the joint by tolerating more OD wear.
Field Repairable - The XT can be refaced in an inspection yard or at the rig site with a portable refacing tool. This can save time and expenses by eliminating shipping and handling costs.
