tool-joint tapered thread

Influence of the Technological Gap Value of the Tool-Joint Tapered Thread on the Drilling Mud Flow Rate in Its Screw Coupling

Tightness is one of the parameters of the quality of pipe drill string. Consequently, the reduction of hydraulic costs and wear of the tool-joint tapered thread of the drill string can be achieved by changing the cutting part of the cut tools.

About the Functional Dependence of the Tool-joint Tapered Thread Half-angle Profile From the Back Rake Angle Value, Side Rake Angle Value and Half Angle Of the Profile of the Cutting Edge of the Tool

The proposed application concerns exactly tool-joint tapered thread of all sizes. The application through which you can get half— angle cutting edge profile of the tool through which the required accuracy of the tool-joint tapered thread profile is provided.
